An HVAC system is an essential part of any home or building. The HVAC system is made to help control the temperature conditions within a building to create a comfortable environment through heating and cooling the space. Energy-efficient HVAC units require less energy to work, which means they’ll spend less money on energy bills in the short and long run. Learn how Aeroseal can help they achieve significant energy savings when it comes to the home's heating and air conditioning systems. What Makes an HVAC System Energy Efficient? When it comes to devices and machines, energy efficiency is the first thing people look for When it comes to devices and machines, energy efficiency is the first thing people look for. It is no different for HVAC systems, which can take up a significant portion of a home's energy costs. Different factors will make an HVAC system energy efficient. The type of system they have can have a major impact on energy efficiency. Because of this, even small changes to an existing system can help make it more energy efficient. Energy-Efficient HVAC Rating Systems When it comes to finding the most energy-efficient HVAC system, it helps to have an understanding of the science behind them. Here are some of the different scientific ratings that most energy-efficient HVAC systems will be rated with: Seasonal Energy Efficiency Ratio (SEER): SEER is the measured ratio of cooling output, which is measured in British Thermal Units (BTU) and then divided by usage, measured in kilowatt hours. For the SEER rating, the higher the number, the more energy efficient the HVAC ducting they have. The SEER HVAC rating uses seasonal cooling conditions rather than lab-created conditions. Energy Efficiency Ratio (EER): Another rating that most energy-efficient residential HVAC systems will have is an EER rating. The EER rating does not use seasonal averages to get its ratios. Instead, it uses strict laboratory conditions for its testing. Like with the SEER rating, the higher the EER number, the more energy efficient the HVAC system is. Heating Seasonal Performance Factor (HSPF): The HSPF rating is the ratio for how efficient the HVAC’s heat pump is, which cycles in both directions to produce hot and cold air. The HSPF rating measures exactly how much total space heating is necessary, using the BTU measurement divided by the total amount of electricity used by the pump in kilowatt-hours. The higher the HSPF ratio, the more efficient the heat pump is. 18 Tips to Make the HVAC Unit More Energy Efficient So, do I need to invest in a whole new system to increase energy efficiency? Not at all. Just read these 18 tips for some energy-saving adjustments that can make a huge difference in the utility bills and reduce energy consumption. 1. Retrofit An Old Heating and Cooling System Updating the HVAC system is a great option for large, energy-intensive systems that have been well-maintained through their lifetime. They can replace the system’s compressor, add condenser fan controls, and add air side economizers that help take advantage of the cool air outside. 2. Invest in a New Energy-Efficient HVAC System for the Home Alternatively, if they plan on staying in the same home for a long time, they may want to consider purchasing a new HVAC system with more efficient ducting. This is especially helpful if they have an old system. Check for high-efficiency units with high SEER and Energy Star ratings that adhere to strict energy efficiency guidelines. 3. Increase the Insulation of the Space To have the most energy-efficient residential HVAC system possible, they also want to ensure the home itself is well insulated. Insulating the home and the unit’s ducting properly will prevent air from escaping. So, the unit will not have to work as hard to heat and cool the home overall. 4. Use Aeroseal Duct Sealing to Avoid Duct Leakage When they hook up an energy-efficient HVAC unit to a leaky duct system, it completely defeats the purpose by allowing the air to escape before it reaches the inside of the home. This is a costly issue that, unfortunately, is easy for HVAC technicians to overlook. And because of that, it can cost they a lot of money. By using a product like Aeroseal, any cracks and holes can easily be filled, preventing any more air leakage. 5. Install Programmable Controls and Thermostats Programmable thermostats and controls also help to make the most of energy-efficient HVAC units. These systems allow temperatures to be automated, so they can change depending on the time of day. This helps take some of the heavy workload off the HVAC system. A simple change of temperature during the day, when nobody is home, can drastically decrease the amount they spend on the utility bills. So, save some extra dough by installing a programmable or smart thermostat. 6. Preserve the System Airflow Keeping the HVAC unit free from dust and debris is essential in maintaining an energy-efficient unit. Dust, dirt, and debris can all clog a system and force it to work harder to push out hot and cold air. Also, they want to ensure that the furniture and curtains are not blocking any of the air vents or ducts, which could prevent air from flowing smoothly and efficiently. 7. Make Use of Curtains and Blinds During summer months, keeping curtains closed during the day will help block out some of the summer heat, allowing the home to maintain a cooler temperature. Alternatively, opening the curtains during winter will allow even the smallest amount of sunlight to come through and naturally warm the home, so the HVAC system works less. 8. Perform Regular Maintenance to Save Energy It may seem like common sense, but people surprisingly overlook the importance of performing regular maintenance on their unit. At both the start and end of every season, they want to get the system inspected to make sure everything is working to its fullest potential. By having regular maintenance checks, they can avoid being caught by a surprise system failure and costly repairs. 9. Watch the Thermostat If they set the thermostat closer to the outside temperature, then the HVAC system will not have to work nearly as hard to heat or cool the home. This is another reason why installing a programmable thermostat is an outstanding, money-saving idea. That way, it will change the temperature automatically, without they having to constantly watch it. 10. Change Air Filters Regularly As the HVAC system is used, the air filter inside of it gets clogged with dirt, dust, and other types of debris. The dirtier the filter gets, the harder the system is forced to work to do its job, making it use more energy and costing they more on their utility bill. By changing the filter regularly, they can ensure the HVAC system always has a clean air filter, so it can function at its best. 11. Watch When They Run the Dryer and Oven When a dryer is used, it draws warm air into the home while an oven simply creates additional heat. So, when these appliances are used during the hottest point of the day in summer, they increase the home’s temperatures. This forces the HVAC system to work harder in cooling the home, which runs up the utility bills. 12. Take Advantage of Fans to Cool the Home Fans are instrumental in improving the HVAC energy efficiency. No matter if the system is set to cooling or heating, fans will help better circulate the air throughout the house. That way, all areas of the home are getting evenly distributed hot and cold air, and the system doesn’t have to use as much energy. 13. Clean the Drain Line Keeping the drain line clean will help with creating the most energy-efficient home HVAC system setup possible. To clean this line, they can flush a cup of chlorine bleach through the drain, followed by a gallon of water to help rinse it through. Doing this will help keep the drain clean all summer and will help make sure the basement doesn’t flood from a blocked drain. 14. Trim Plants and Clean Gutters Another thing they can do to create better conditions for energy efficiency is to trim the plants and clean out the gutters. These things hold moisture, and if moisture gets onto or into the HVAC system, it can reduce its functionality. Keeping it free from fallen foliage and moisture is vital. 15. Place the Outdoor Unit in a Shaded Area If an HVAC unit is placed in an area with excessive sunlight, it can cause it to overheat and use more energy to cool the home. Placing it against the home in an area that doesn’t get excessive amounts of sunlight will allow it to maintain a consistent temperature, so it doesn’t have to use more energy to cool the home. 16. Have the Right HVAC System Size Having a system that’s too small for the home can force the system to work harder to heat and cool the space. Alternatively, a system that’s too big may be overkill and put out too much energy. Talk to a professional to figure out what size HVAC unit is best for the home. 17. Get Proper Duct Sizing The ductwork of the HVAC system runs throughout the home, helping to distribute heated and conditioned air throughout. Because of that, it is essential to ensure they choose their ductwork in the correct size. If ducting is too small, it will reduce the overall airflow and minimize the HVAC’s performance. Alternatively, if the ducting is too large, the air may get lost, and the HVAC would have to work even harder to heat and cool the entire house. 18. Consider Duct Design When they’re trying to reach the entire house with the HVAC system, the design of the ductwork is critical. Beyond the sizing, the shape, number of bends, and overall layout of the ducting affect how the air flows through the system. With longer distances to travel or more bends in the design, the HVAC system will have to work harder to move air throughout the home, and some air may end up lost in its path to the different rooms. Achieve Greater HVAC Efficiency with Aeroseal Whether they’re trying to lower utility bills or be more green when it comes to energy usage, these 18 tips can help they use their HVAC’s energy more efficiently. Sealing duct leaks with Aeroseal is one simple way to keep the HVAC running efficiently and effectively.

Rooter Hero Plumbing & Air, a plumbing and HVAC company serving residential and commercial locations in California and Arizona, says that the high cost of a four-year university and the ability to earn a good living quickly are two reasons graduating high school seniors should consider a career in the skilled trades industry. “A series of international trade agreements that moved factories abroad, a stigma against blue-collar workers, and authority figures pushing college over trade school motivated young people to steer clear of the skilled trades,” said Rooter Hero CEO John Akhoian. “That led a whole generation into believing there was either no future in the trades or that you could not earn a living wage as an HVAC technician or plumber. Neither of those myths are true, and we should do a better job of explaining that to graduating seniors.” Rising costs of college As more high school graduates opted to go to universities in the 1970s, the cost of attending college also began its steep incline. Beginning in the late 1980s and continuing today, the price tag of a college degree has skyrocketed so much that most students are forced to take out thousands of dollars in student loans to get an education. Akhoian said that many careers also require a bachelor’s or master’s degree, which means four to six years in school, while most trade schools take only 18 to 24 months to graduate. “That means that you can get started on your career—and start earning a paycheck—earlier in life,” he said. “If you get an apprenticeship, you can even earn a living while you learn. These jobs are also stable and pay well. Plumbing and HVAC jobs cannot be outsourced or moved to another part of the country.” Choosing a Career in the Trades Akhoian personally knows the benefits of choosing a career in the skilled trades industries at a young age. When he was a teenager, his father died, leaving Akhoian with the arduous task of providing for his family. With no skills to lean on, the Rooter Hero founder became an apprentice plumber at 17 years old, where he learned the ropes before starting his first plumbing company at 19 years old. “The trades are great careers that workers can take pride in,” he said. “If you like working with your hands, solving problems and want to start a lucrative career quickly, you can’t go wrong by choosing to be a plumber, an HVAC technician or an electrician.”

Rooter Hero Plumbing & Air, a plumbing and HVAC company serving residential and commercial locations in California and Arizona, says that the high cost of a four-year university and the ability to earn a good living quickly are two reasons graduating high school seniors should consider a career in the skilled trades industry. “A series of international trade agreements that moved factories abroad, a stigma against blue-collar workers, and authority figures pushing college over trade school motivated young people to steer clear of the skilled trades,” said Rooter Hero CEO John Akhoian. “That led a whole generation into believing there was either no future in the trades or that you could not earn a living wage as an HVAC technician or plumber. Neither of those myths are true, and we should do a better job of explaining that to graduating seniors.” Rising costs of college As more high school graduates opted to go to universities in the 1970s, the cost of attending college also began its steep incline. Beginning in the late 1980s and continuing today, the price tag of a college degree has skyrocketed so much that most students are forced to take out thousands of dollars in student loans to get an education. Akhoian said that many careers also require a bachelor’s or master’s degree, which means four to six years in school, while most trade schools take only 18 to 24 months to graduate. “That means that you can get started on your career—and start earning a paycheck—earlier in life,” he said. “If you get an apprenticeship, you can even earn a living while you learn. These jobs are also stable and pay well. Plumbing and HVAC jobs cannot be outsourced or moved to another part of the country.” Choosing a Career in the Trades Akhoian personally knows the benefits of choosing a career in the skilled trades industries at a young age. When he was a teenager, his father died, leaving Akhoian with the arduous task of providing for his family. With no skills to lean on, the Rooter Hero founder became an apprentice plumber at 17 years old, where he learned the ropes before starting his first plumbing company at 19 years old. “The trades are great careers that workers can take pride in,” he said. “If you like working with your hands, solving problems and want to start a lucrative career quickly, you can’t go wrong by choosing to be a plumber, an HVAC technician or an electrician.”

As demand continues to grow for sustainable, energy-efficient solutions in refrigeration and heating, both Europe and North America are navigating a rapid transition toward natural refrigerants. There is a strong demand for new CO2 systems, including heat pumps and various other applications. Higher capacity compressors with larger operating envelope, such as Danfoss’ Bock HGX56 CO2 T series, will play a critical role in supporting this growing need. Air to water heat pumps As shown in Figure 1 and Figure 2 below, the larger operating envelope of up to 77°F and 65 bar on the suction side can improve the COP by approximately 15% for applications with higher heat source temperatures – for example, air to water heat pumps in summer conditions. Transcritical CO2 figure. Larger operating envelope of up to 77°F and 65 bar on the suction side. Figure 3 below shows a typical layout of a CO2 transcritical air-to-water heat pump for large systems, designed with features to boost efficiency. Such systems are already being built in Europe, with the largest compressor options, and used in heating capacities of up to 2.5 MW per rack. Layout of a CO2 transcritical air-to-water heat pump for large systems. Cooling and Heating Working Together Transcritical supermarket applications with heat reclaim are very suitable for improving the version Transcritical supermarket applications with heat reclaim are very suitable for improving the overall refrigeration system performance. It is a highly efficient and resilient solution that provides simultaneous heating and cooling by recycling waste heat energy within the store. More than 2,000 installations across Europe and in other parts of the world have shown that the traditional CO2 weaknesses in refrigeration applications, such as high temperatures and pressures, can be turned into profitable advantages when adding heat reclaim to the system. In fact, the operational costs can be reduced by more than 20% by replacing conventional heating sources with heat reclaim, and the pay-back time of the heat reclaim installation is typically short, less than 2.5 years. At the same time, huge carbon savings can be made when the system is installed and maintained correctly. Additional Applications Transitioning to CO2 CO2 is increasing in popularity for cold storage and food processing, due to some challenges of using ammonia in states with a large number of regulations, as well as the desire for distributed systems when expanding plants and the advent of larger CO2 compressors. Some estimates show a 10% market transition to CO2 from ammonia and HFCs for systems up to 250 tons (880 kW). An example would be a cold storage facility requiring variable temperatures with stability/efficiency at partial load for garlic processing, storage and pre-cooling. The requirements for pre-cooling are 40°C/39.20°F, but for processing and final storage, −100°C/140°F is required. CO2 System Examples Single-stage transcritical CO2 applications are used in the field of medium temperature refrigeration Single-stage transcritical CO2 applications are used in the field of medium temperature refrigeration. They can be operated very efficiently, if the high pressure is operated in the subcritical range over a long period. Using the high-pressure side, it is appropriate to use the application in the transcritical range in combination with refrigeration, due to a large temperature glide and a relatively high discharge end temperature for specific heat pumps and the heat recovery. In CO2 applications in low and medium temperature refrigeration, so-called booster systems are used. High-pressure CO2 gas from the low-temperature compressor is discharged directly to the suction side of the second compressor stage. Different plant constructions of these Booster applications are used, for example, in supermarket applications. In a cascade system, different refrigerants are used in an application. They are combined in two refrigerating circuits that are separated from each other. The high temperature stage is used as a condenser in the CO2 application. It is possible to use different refrigerants like hydrocarbons, ammonia, and HFCs like R-134A. Keys to a Successful Installation Proper oil levels, adequate space for maintenance and ventilation, environmental conditions and surface setup with sufficient load-bearing capacity are all critical initial items to consider. Once these items have been considered and addressed properly, then you need to take extreme care during the soldering - cooling the valve body during and after and only using inert gas to inhibit oxidation products. The actual required pipe cross-section must be matched to the output. The tube must be sawed at a right angle with the angular tolerance being ±10. Pipes and system components must be clean and dry inside and free of scale, swarf and layers of rust and phosphate. Only use hermetically sealed parts. Lay pipes correctly. Suitable vibration compensators must be provided to prevent pipes being cracked and broken by severe vibrations. Ensure a proper oil return and keep pressure loss to an absolute minimum. Suction and discharge should be depressurized prior to connecting to the refrigerant system. Proper layout of the suction and pressure lines directly after the compressor is integral to the smooth running and vibration behavior of the system. Oil return function To ensure the oil return function will work reliably no matter what kind of system configuration you are using, Danfoss recommends incorporating oil separators or oil level monitoring equipment. For systems with long pipes and higher degree of contamination, a filter on the suction-side is recommended. When attaching accessories with an electrical cable, a minimum bending radius of 3x the cable diameter must be maintained for laying the cable. Voltage and frequency values Compare the voltage and frequency values with the data for the mains power supply Connect the compressor motor in accordance with the circuit diagram (see inside of terminal box). Compare the voltage and frequency values with the data for the mains power supply. Only connect the motor if these values are the same compressors marked in this way are suitable for direct or part winding start. The motor winding is divided into two parts: part winding 1 = 50 % and part winding 2 = 50 %. This winding division reduces the start-up current during a part winding start to approx. 50 % of the value for a direct start. Reversed fields of rotation In the factory, as shown below in Figure 4, the motor is switched for direct starting (YY). For part winding start (Y/YY), remove the bridges and connect the motor feed cable according to the circuit diagram. The motor is switched for direct starting (YY). Failure to comply results in reversed fields of rotation and can cause motor damage. After the motor has started up with part winding 1, part winding 2 must be switched on after a maximum 1-second delay. Failure to do so can be detrimental to the service life of the motor. Ensure that power is supplied via QA2 to winding 1 (50%) (1U1/1V1/1W1) and via QA3 to winding 2 (50 %) (2U1/2V1/2W1). The motor contactors (QA2/QA3) are each to be rated for approx. 50% of the maximum operating current. Danfoss BOCK compressors Transcritical CO2 compressors, like the Danfoss BOCK product line, offer a wide span of capacities with up to 162 kW of cooling capacity (14°F/95°F/18R/60 Hz) and 420 kW of heating capacity (41°C/77°C (100 bar)/18R/60 Hz) for many different product applications, including food retail, heat pumps, district heating, industrial refrigeration and process heating, reversible chiller/heat pumps for HVAC, cold storage, chillers, and data centers. Low and medium temperature levels are available, with high stand still pressures. This high capacity reduces the need for multiple compressors, simplifying system design and reducing investment costs. The Danfoss BOCK compressors also feature a high-pressure rating of 130 bar in operation/150 bar at stand still on the high side and 65 bar in operation/100 bar at stand still on the low side.
Although energy efficiency continues to be a focus of home renovation, HVAC professionals are sometimes hesitant to work on older homes. The potential costs and complexities of replacing outdated HVAC systems or installing a solution where one doesn’t exist can make them nervous. However, installing all-electric, all-climate heat pumps in homes built decades ago, even a century ago, is an everyday occurrence in the northeastern U.S. Heating and cooling systems A sizable portion of Jay Moody Heating & Air Conditioning consists of installing and servicing energy-efficient heating and cooling systems, especially heat pumps, in older homes in central Massachusetts. Updating older homes with heat pump solutions is more feasible than many think — it’s a matter of overcoming common barriers and being the right, experienced HVAC professional for the job. Common barriers when heating and cooling an older home In Massachusetts, it’s common to have one or more 275-gallon tanks of oil in the basement to heat homes Barriers to renovating older homes are surmountable. Commonly, older homes lack adequate filtration and insulation and are equipped with older electrical panels that might need upgrading or replacing. In Massachusetts, it’s common to have one or more 275-gallon tanks of oil in the basement to heat homes. However, whether an older home is heated with oil or gas, outside air infiltration occurs because these structures generally lack a tight building envelope. More recently built homes have these systems to prevent outside air and water from penetrating the structure. Similarly, many older homes are insufficiently insulated. Size of the structure and other electrical loads As a first step, owners of older homes should get an energy audit and find out what can be done to eliminate infiltration, such as having air sealing performed and having more insulation blown into their houses. Once weatherization is complete, installing an all-electric heat pump system becomes more feasible. Another important requirement would be an appropriately sized electrical panel. Older homes might have 100 amps of service, for example, when it will need 200 amps for the new heat pump, depending on the size of the structure and other electrical loads such as electric stoves/ovens, water heaters, and electric vehicles. In some cases, an electrical panel upgrade may be required. Attributes homeowners look for in an HVAC company HVAC companies that specialize in heat pumps should ensure their HVAC technicians are shared and ongoing training When upgrading an older home with a heat pump system, it’s a best practice for homeowners to get multiple quotes from experienced contractors in their service area. To stand out and offer more value during this process, my business conducts monthly heat pump workshops that help educate customers. Additionally, I recommend that any experienced, reputable HVAC company should post online reviews, have a professional website and online presence, and show relevant work examples to help familiarize homeowners with their work. HVAC companies that specialize in heat pumps should ensure their HVAC technicians are experienced and undergo ongoing training. In fact, the Jay Moody team is part of the Mitsubishi Electric Diamond Contractor® program, which provides in-depth training on heat pump solutions. Homeowner’s comfort preferences During the in-home consultation, the salesperson should discuss the homeowner’s comfort preferences, HVAC concerns, and short- and long-term plans for the home and its HVAC system. The contractor should conduct an in-house Manual J to calculate the heating and cooling loads of the home, ensuring proper HVAC equipment sizing for efficient and comfortable performance. Lastly, the HVAC salesperson should make suggestions for keeping the aesthetics of an older home intact. For instance, my team would not use mini-splits in certain rooms in a Victorian home because they might detract from the style. Instead, they would likely suggest a ducted heat pump system with air handlers and stylish vents. HVAC salesperson should make suggestions for keeping the aesthetics of an older home intact. Heat pumps offer the right fit for homes of all ages In the Northeast, many of the homes are older – whether that means built in the 1960s, the 1860s, or the 1760s. There’s little reason that any HVAC contractor should shy away from installing heat pump systems in older homes. Further, contractors can learn how to teach homeowners about heat pumps, train their teams, and recommend the right system for the character of the house. Refurbishing these beautiful houses is a challenge well worth tackling to create homes as energy-efficient and comfortable as they are charming.

Data centers play a pivotal role in supporting the flow of information across our digital economy. However, the transmission of large amounts of data also requires a lot of energy. Viewing data centers as potential heat sources offers an opportunity to use this otherwise wasted heat to warm nearby homes and businesses using technologies like heat pumps and heat networks. The approach will lower the environmental impact of these buildings filled with computer servers, and it will support the transition to renewable heating as we look toward net zero. Heat recovery systems Heat recovery systems are designed to facilitate the re-use of heat energy via technologies like heat pumps Heat recovery systems are designed to facilitate the re-use of heat energy via technologies like heat pumps and heat networks, says Simon Prichard, EMEA ITC Business Leader, Mitsubishi Electric, within the Living Environmental Systems division. The heat generated by data centers, usually around 30-35°C (85-90°F), is increased by heat pumps to 70-80°C (160-175°F), making it suitable for heating nearby buildings or supplying hot water. “However, when choosing which heat recovery approach to go for, it's important to take into account the data center’s size, location, and proximity to the desired reuse location,” says Simon Prichard, adding “These factors determine the most efficient method for heat recovery and distribution.” Reusing heat from data centers via heat pumps “Reusing heat from data centers through heat pumps and heat networks drives down costs by reducing the amount of heat going to waste and ultimately increasing energy efficiency,” continues Simon Prichard. However, Simon Prichard emphasizes these cost benefits must be communicated and outlined clearly to ensure stakeholders are aware. More awareness will, in turn, drive adoption forward. Wider awareness and adoption Wider awareness and adoption are already happening with plans for utilizing waste heat within London's district heating networks, notes Prichard. The scheme uses ejected heat from a data center to power heating demand for nearby homes A real-life example is Amazon’s Tallaght data center in Dublin, which is the country's first low carbon district heating network. The scheme uses ejected heat from a data center to power heating demand for nearby homes, and peak requests in winter are satisfied by dedicated heat pumps and a heat pump module. The network is estimated to reduce pollutant emissions in the South Dublin County region by nearly 1,500 tons per year. Mitsubishi Electric’s CPD-Certified Guide Mitsubishi Electric’s newly released CPD-Certified Guide aims to educate data center owners, managers and policymakers on the role heat reuse can play in decarbonizing these buildings. “It provides insight into how we can reduce the carbon footprint of these spaces by viewing them as a source of heat energy, as well as the solutions available and what needs to be considered before making the switch,” says Simon Prichard, adding “In doing so, it aims to support owners and managers in transitioning to heat recovery in their building and reducing the environmental impact of these spaces to support the United Kingdom’s wider journey towards net zero.” Communicating the benefits of heat reuse in data centers “Communicating the benefits of heat reuse in data centers can promote greater cooperation from stakeholders – whether that's owners and managers, governments, or manufacturers,” says Simon Prichard. Raising awareness of the environmental impact of data centers and the role heat recovery can play in reducing that impact can position data centers as part of the solution for a decarbonized future. Developing heat networks “Continuing to develop heat networks at the same scale as other European countries will also help make reusing this energy to heat surrounding buildings a reality and put what we see across other countries into practice in the UK,” states Simon Prichard.
The U.S. Department of Energy (DoE) Commercial Heat Pump Accelerator program is designed to enhance building efficiency and electrification. Running from 2024 through 2027, the program aims to overcome adoption barriers, promote advanced heat pump technologies, and create sustainable solutions for HVAC professionals.

Known for their dual heating and cooling capabilities, heat pumps save energy compared to conventional HVAC systems. The Accelerator program prioritizes cutting-edge systems to lower energy consumption and operating costs for businesses. As decarbonization becomes a global priority, electrification of HVAC systems is also key. By reducing reliance on fossil fuels, heat pumps contribute to a cleaner energy future. Practical Benefits for Professionals For HVAC professionals, the program provides a framework to explore new markets and enhance service offerings. With the Accelerator program’s emphasis on efficiency, HVAC professionals can help clients reduce energy bills, providing a tangible ROI for heat pump installations. Participants in the program also gain access to technical guidance, best practices, and case studies, fostering skills to implement heat pumps effectively. As building owners seek energy-efficient solutions, HVAC professionals are positioned as experts in heat pump technology in order to gain a competitive edge. Success of the residential challenge The retail program is a growth of an earlier program related to residential technologies The commercial program is an expansion of an earlier program related to residential technologies. Last fall, the U.S. Department of Energy (DOE) announced that eight manufacturers in the Residential Cold Climate Heat Pump Challenge completed rigorous product field testing to demonstrate energy efficiency and improved performance in cold weather. Bosch, Carrier, Daikin, Johnson Controls, Lennox, Midea, Rheem, and Trane Technologies participated in the residential challenge.

Hydronics systems rely on water, steam, or water solutions to distribute heating and cooling throughout a building. They are inherently more eco-friendly than conventional alternatives. First and foremost, using water as a temperature regulation method is a natural choice. There is no carbon footprint involved in its creation, and there is no inherent danger in exposure to water in the event of a system failure. Water is more efficient at carrying heating and cooling loads than other technologies. Other benefits include a wider range of maintenance flexibility and longer system life expectancy. overall efficiency of hydronics “A misconception about hydronics is that it's more expensive compared to other HVAC systems,” says Jim Nolan, market development manager, Xylem. “While hydronic systems may require a larger upfront investment, lifecycle costs are significantly lower due to the overall efficiency of hydronics.” Flexibility in Cold and Warm Climates Hydronics offers a wider range of flexibility for components, operation, and maintenance Compared to other systems, hydronics offers a wider range of flexibility for components, operation, and maintenance. That flexibility also extends to extreme climate conditions, says Nolan. Hydronics perform reliably at very cold and very warm temperatures for improved occupant comfort and reduced energy costs. Additionally, hydronic systems draw on water’s natural thermal storage capabilities, which can substantially offset operating costs during peak demand periods. For over 100 years, Xylem’s Bell & Gossett has been at the forefront of hydronic systems as a manufacturer of pumps, valves, heat exchangers, and accessories — including steam and heat transfer — for plumbing and wastewater applications. Since 1916, the company has made a name for itself through products, industry-pioneering training at the Little Red Schoolhouse, comprehensive solutions, and application expertise, says Nolan. Products and sustainability efforts “Xylem is continuously innovating to advance and embed sustainability holistically into our solutions – from the materials we source, to making them more compact and cutting emissions, to high-efficiency motors,” adds Nolan. Advancing the efficacy and efficiency of their foundational products is what Bell & Gossett is known for, and more broadly, what Xylem is doing to embed “high impact” into all its products and sustainability efforts, says the company. Quantifiable Effect on Decarbonization Smart pump solutions like Xylem’s Hydrovar® X Smart Motor tout ultra-premium efficiency As the built environment increasingly weighs the effects of climate change and decarbonization, products must keep pace to demonstrate quantifiable impact on addressing these challenges. Smart pump solutions like Xylem’s Hydrovar® X Smart Motor tout ultra-premium efficiency, sustainably sourced materials, and compact design, delivering high impact in terms of intelligence and productivity. Built-in condition monitoring empowers customers to leverage data for additional pump protection and optimized performance. Equally essential is continued education and collaboration with industry partners to help commercial building owners navigate the challenges of achieving decarbonization and net-zero goals, says Nolan. That includes training opportunities at Bell & Gossett’s Little Red Schoolhouse to teach industry professionals about sustainable solutions, he adds. Ideal distribution system “Water is considered technology agnostic – no matter what type of technology exists today or in the future, modern hydronic systems can easily adapt to a variety of energy sources,” says Nolan. “As solar and geothermal grow, building owners and designers are recognizing that hydronics provide an ideal distribution system for these alternative technologies to perform.” Hydronic system efficiency is already well-documented in thousands of real-world applications, says Nolan. Hydronics reduces operating costs by using water as a heat transfer medium, which is more effective than air. Efficiency and cost savings are maximized when these systems are powered by renewable energy sources. Overcoming Obstacles to Equipment Reuse In some cases, though, existing HVAC equipment may be too outdated for reuse In some cases, existing HVAC equipment can be reused to achieve sustainable, carbon-neutral systems, says Nolan. Adaptive reuse projects involve repurposing an existing building for new use and reusing as much existing equipment as possible to save costs, conserve resources, and minimize construction-related disruptions. Upgrading existing hydronic systems with smart technology like advanced controls and smart motors can improve performance and efficiency, says Nolan. Another option is to incorporate high-efficiency components like heat pumps. In some cases, though, existing HVAC equipment may be too outdated for reuse. In others, existing building footprints may limit design options. To overcome this, a thorough assessment of current building conditions and performance can provide a better understanding of the original system design. Identify ways to reduce energy consumption Energy audits, building performance evaluations and environmental impact assessments provide valuable insights into an existing building’s energy consumption, resource usage and environmental footprint. The purpose of these tools is to identify ways to reduce energy consumption or operating costs by upgrading to more energy-efficient equipment or by building a better system. “There’s a whole industry built around energy audits—they’re typically conducted by industry professionals who have qualifications or certifications to ensure they have the knowledge and skills to perform thorough and accurate assessments,” says Nolan. Challenges to Deregulation and Achieving Net Zero Deregulation or the elimination of natural gas in existing buildings presents challenges. While hydronic equipment is essentially decarbonized because it runs on electricity, many utilities still rely on fossil fuels. Only when those providers switch to renewable energy and the grid infrastructure is expanded to deliver enough electricity will environmental impact be realized. Although many areas are moving toward decarbonization and achieving net-zero energy, in regions where energy is cheap, there are few incentives to embrace renewable energy and building electrification. As HVAC equipment becomes more efficient and uses less energy, communities will realize the cost savings and gravitate toward better technology.

Wren emphasizes transparency by providing regular updates on the impact of contributions, including data, photos, and stories. The platform aims to make climate action simple and effective, ensuring that every dollar contributes to meaningful environmental change. About A-Gas A‑Gas is a world pioneer in the supply and lifecycle management of refrigerants and associated products and services. Through the first-class recovery, reclamation, and repurposing processes, we capture refrigerants and fire protection gases for future re-use or safe destruction, preventing harmful release into the atmosphere. For over 30 years, A-Gas has supported clients and partners on their environmental journey by supplying lower global warming gases and actively increasing the circularity of the industries we serve, building a sustainable future. Challenge HCFC-22 is a potent greenhouse gas with a global warming potential (GWP) much higher than CO2 The widespread use of refrigerants like HCFC-22 (R22) presents a significant environmental challenge. HCFC-22 is a potent greenhouse gas with a global warming potential (GWP) much higher than CO2 (one molecule of R22 has a global warming impact 1,810 times that of one molecule of CO2). If not properly managed, its release would have a negative impact on the atmosphere. As these refrigerants reach the end of their lifecycle, there is an urgent need for effective solutions to prevent their emissions and minimize their environmental impact. Solution To address this challenge, A-Gas recovers refrigerants for reclamation or destruction at A-Gas facilities across the country. By leveraging Wren's platform to mobilize individual contributions and A-Gas' technical expertise in lifecycle refrigerant management, this partnership enabled an environmentally conscious solution for the used refrigerant. It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry through its on-site refrigerant recovery service (Rapid Recovery®), refrigerant buyback programs, and wholesale supplier reclaim program (Refri-Claim™). HCFC-22 destruction project The ACR methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017 Wren and A-Gas formed a partnership to provide Wren subscribers with the opportunity to fund an HCFC-22 destruction project through the generation of A-Gas carbon credits to ensure the gas does not escape into the atmosphere. While the ACR (formerly American Carbon Registry) methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017, few have completed such projects because the price of HCFC-22 is so high; it is more profitable for organizations to reclaim this product. ACR’s methodology As such, this is one of the first HCFC-22 destruction projects utilizing ACR’s methodology. Approved by the International Civil Aviation Organization (ICAO) to provide carbon credits in its Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), ACR is highly regarded across the world. Results The partnership yielded multiple environmental benefits: Emissions Avoided: The initiative successfully avoided the release of 16,000 tons of CO2-equivalent emissions by destroying HCFC-22. This substantial elimination of greenhouse gas emissions demonstrates the effectiveness of the program. Subscriber Engagement: Wren provided its subscribers with detailed updates on the impact of their contributions. These updates included data on the quantities of HCFC-22 destroyed and the corresponding emissions reductions. This transparency helped build trust and encouraged ongoing participation in climate action. Educational Impact: The collaboration raised awareness about the importance of proper lifecycle refrigerant management. Wren and A-Gas educated the public on lesser-known aspects of climate change mitigation by highlighting the environmental benefits of destroying high-GWP substances. Conclusion This partnership enabled an environmentally conscious solution for the used refrigerant By leveraging Wren's platform to mobilize individual contributions and A-Gas' technical expertise in lifecycle refrigerant management, this partnership enabled an environmentally conscious solution for the used refrigerant. It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry. refrigerant destruction protocols and technology "We are excited to work with A-Gas to push forward the standard of refrigerant destruction protocols and technology," said Landon Brand, CEO, of Wren. Landon Brand adds, "This is one of the most reliable and impactful project types we have found in our years of funding climate solutions, and we hope our community can keep blazing a trail to eliminate these dangerous refrigerants."
The Olsen Group, based in Boca Raton, Florida, is a national pioneer in HVAC energy optimization. Donald Olsen and his seasoned team of HVAC control specialists have been in business for two decades, integrating energy-saving solutions into over a thousand commercial and large-scale residential projects. In the process, the Olsen Group has become one of North America’s top suppliers of Verdant thermostats. Verdant devices leverage intelligent occupancy sensors and proprietary software to reduce HVAC runtimes by 45 percent on average. HVAC control integration Verdant’s effectiveness, reliability, and broad compatibility have made Verdant the energy management solution of choice for thousands of hotels and MDUs, including multifamily buildings, senior living, and student housing. The Olsen Group has forged a productive two-way partnership with Verdant. Donald Olsen and his team have made it a priority to share data, customer feedback, and requirements with Verdant – and Verdant, in turn, has come to rely on Olsen when they need to field test a new solution. In May of 2024, Verdant reached out to Olsen for help with a new pilot program aiming to facilitate more effective HVAC control integration, easier service, and deep energy savings for MDU projects around the globe. The Challenge Commercial VRF systems have an extremely attractive set of upsides for hotel operators Inverter (VRF) system design is becoming increasingly common in hospitality settings. Commercial VRF systems have an extremely attractive set of upsides for hotel operators. They are significantly more energy efficient and quieter than traditional VTACs or PTACs; they can provide simultaneous heating and cooling to different zones for optimal guest comfort; and they allow both individual room-level setpoint control and building-level centralized management. However, the majority of VRF units cannot connect directly to a third-party smart thermostat. Because they rely on proprietary manufacturer protocols for variable speed commands and internal diagnostics, VRF units require an external control solution to facilitate bidirectional communication with Verdant thermostats. Installation and commissioning process Every additional component in a system adds complexity and opportunity for human error. In hotels, that complexity is multiplied across hundreds of rooms. “HVAC systems are installed dark for new builds, with no power running to the site,” says Donald Olsen, President and Owner of the Olsen Group. “There’s no way to test as we go. If there are any mistakes during installation, we find out about it when the lights go on after project completion.” And mistakes are nearly inevitable. Some third-party controllers have prominent dipswitches that can be easily snagged or tripped during transportation or installation, altering their configuration and causing them to fail once the system is powered. These switches are often accidentally tripped multiple times throughout the installation and commissioning process, pioneering to a never-ending cycle of errors and service calls. VRF control solutions Adding to the issue, not all third-party control keys have the ability to retrieve and solve system error codes “Once properly configured and installed, VRF control solutions tend to be incredibly reliable,” says Olsen. “Getting them there is a real challenge, however. Accidents, human error, and repeated recalibrations can drive serious project overruns and client dissatisfaction.” Adding to the problem, not all third-party control solutions have the capability to retrieve and translate system error codes. “If the central management system isn’t getting certified manufacturer control signals from the control device, it may no longer recognize the thermostat. The system will continue to function, but it will always show up in the central manager with an error message,” warns Olsen. Airzone Aidoo Pro control solution These false error reports degrade the overall utility of the central management system, robbing operators of the ability to detect and mitigate problems proactively and requiring onsite testing to diagnose any issues. As VRF systems become the norm for hospitality projects, Verdant needed a solution to reduce the possibility of accidental misconfiguration and improve visibility into system functionality. They called on Olsen to conduct a pilot program, retrofitting sixteen VRF units in the Jacksonville Beach, FL Springhill Suites with the Airzone Aidoo Pro control solution. The Solution For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller The Jacksonville Beach Springhill Suites is a 156-room hotel with a state-of-the-art Daikin VRV rooftop chiller system. The Airzone Aidoo Pro ships preconfigured for the specific HVAC unit model, reducing the possibility for errors during initial installation. For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller. This 1:1 system design simplifies operations and troubleshooting: Any issue can be immediately traced back to a single unit, minimizing the scope and duration or repair downtime. “The Airzone Aidoo Pro offered two key upgrades as a VRV control solution,” says Olsen. “First, the dipswitches are recessed, making them much harder to trip accidentally. Second, Aidoo makes the system much easier to service. We can read error codes, run tests, and diagnose issues remotely, without ever needing to disrupt a guest’s stay.” Airzone’s expansive library This advanced remote management is enabled by Airzone’s expansive library of manufacturer protocols. “Because of our close relationship with HVAC manufacturers, Aidoo Pro can provide the proprietary control signals the central management system is expecting to see,” says Borja Fernandez, Director of OEM Solutions, Airzone. “That preserves all the features of the HVAC unit and thermostat, while also eliminating persistent false error codes. With Aidoo Pro, the central management system can function as a single-pane-of-glass HVAC monitoring and control solution for the building, as intended.” Results and Next Steps The pilot program is expanding to new builds around the globe, including projects in the UK Olsen reports that Springhill Suites is happy with their upgraded VRV system. “They have more visibility into the system and fewer services calls,” says Olsen. “When there is an issue, we can diagnose it remotely for faster resolution and less guest room downtime. It’s a much better customer experience overall.” Verdant is encouraged as well. This pilot program is expanding to several new builds around the globe, including projects in Central America, the Caribbean, the UK, and the EU. HVAC energy savings “There is a massive untapped market for energy-efficient HVAC upgrades in the Caribbean region,” says Olsen. “Energy costs there can exceed a dollar per kilowatt hour. Cost-effective devices like Verdant thermostats and the Airzone Aidoo Pro pay for themselves very easily in that scenario.” Verdant and the Olsen Group have built global brands by helping commercial properties realize significant HVAC energy savings. Through the Airzone Aidoo Pro pilot program, they are continuing to innovate, enabling reliable integration and enterprise-grade control on highly efficient VRF units. “The demand for commercial VRF control is definitely there,” says Olsen. “With Verdant and Airzone, we can deliver it with ease.”
With a reputation for uncompromising integrity, HDG Legacy is an experienced voice in the hospitality industry for those looking to build, own, and operate hotels. As both a respected developer and preferred management company, the Legacy team employs its core values of teamwork, communication, innovation, leadership and resourcefulness, and has an established reputation for positively impacting the hospitality sector. Currently, Legacy manages and maintains nine hotels that it owns, with its tenth opening July 2025. Rising energy and water costs A commitment to improving and innovating hotels means that Legacy is alive to the economic challenges facing hoteliers, not least in operational challenges because of rising energy and water costs. With profit margins often razor-thin, even small innovations can mean the difference between profit and loss, so it was no surprise that Legacy looked to Anacove’s unique AI- and Cloud-powered Smart Thermostats, Leak Detection and Asset Management systems to help give its hotel clients the edge in their energy and water management. Anacove’s Smart Thermostats “One of my core beliefs is that operating a business that respects the environment in terms of how resources are utilized is important just because that's the right thing to do – but there's also an economic benefit,” explained Navroz F. Saju, Founder and Principal at HDG Legacy. “We initially tested Anacove’s Smart Thermostats across our express properties, before piloting them in one of our larger hotels, and we were so impressed with the results (we actually have the data showing the savings for 2024-25 thus far – very impressive!) that we are looking to roll out the solutions across our other properties.” Electricity consumption reduced He continued, “We started using Anacove Smart Thermostats in July 2024 at the Holiday Inn Express Crystal River, and based on historical data and usage, electricity costs on our utility bills are 35.94% lower per occupied room.” “The Holiday Inn Express & Suites Silver Springs-Ocala’s electricity costs were 33% less than what we’d budgeted for per room, with the Holiday Inn Express & Suites Inverness-Lecanto coming in at 43% lower than budgeted in electricity usage.” Features of Smart Thermostats Anacove’s Smart Thermostats are innovative IoT devices with advanced sensors Anacove’s Smart Thermostats are innovative IoT devices with advanced sensors that monitor temperature, humidity, air quality, barometric pressure, current weather conditions, daylight conditions and guest presence. They seamlessly integrate with HVAC systems through existing hotel WiFi infrastructure, allowing for centralized control throughout the hotel. This enables continuous optimization of each room, regardless of occupancy status, leading to immediate and sustained cost savings. Unlike other occupancy-sensing thermostats, Anacove Smart Thermostats remain active even when guests are asleep or have left their pet in the room. Optimizing HVAC Cycles Learning from each room’s thermal behavior – heating and cooling coefficients – the thermostats optimize HVAC cycles, resulting in reduced peak energy consumption, and maintenance of guest comfort with less energy usage. “I have been very pleased with the transition to Anacove Smart Thermostats, and we will continue to replace older, less efficient thermostat technology with Anacove thermostats,” added Saju. “They are easier to operate – for staff and guests – and install than others on the market – irrespective of their superior energy-saving performance – and are incredibly responsive.” Anacove’s staff and support Such was their ease of use that Legacy’s skilled maintenance staff installed the Anacove Smart Thermostats themselves, but Saju is keen to point out how engaging Anacove was throughout the process. “Their support has been excellent. Even though the thermostats are easy to install and operate, if there is ever a question that needs answering the Anacove team is there to back us up very quickly and in a very expert way,” he said. “I've been very comfortable with their price point – I actually think that their thermostat pricing is the most competitive I have found – and with their after sales service and the technology’s ease of use they are very customer-centric indeed.” Anacove’s AI-enabled water management systems In addition to rolling out Anacove’s Smart Thermostats incrementally across his hotels, Saju is also deploying the company’s AI-powered, cloud-maintained Toilet Leak Detectors and Asset Tracking Systems. The AI-enabled water management systems go beyond basic leak detection. While sensors installed in water tanks or behind walls detect even the tiniest leaks, it’s the AI that identifies anomalies, pinpoints problem areas, and alerts maintenance teams before the issue escalates – saving water, money, repair costs, and mitigating guest inconvenience. Anacove’s Asset Management System Anacove’s Asset Management System equips hotel assets such as luggage carts, rollaway beds, cribs, housekeeping trollies and other movable items with location tags, which, thanks to the cloud-maintained AI system, helps to track down missing items, triangulating their exact positions, streamlining retrieval, reducing loss, and improving overall resource management. “We all expect a lot from our hotel’s front desk,” said Saju. “They’ve got to check people in, the phone's ringing, someone wants a bandage and then suddenly someone will check in and say, ‘where's the luggage cart?’” “The fact that they're immediately able to log in to the Anacove cloud dashboard on their phone and see exactly where the cart is – usually in a guest’s room – is an incredible time-saving benefit, enabling them to locate the cart’s exact location so that they can repurpose the cart for another guest’s use. In the past they would have to ring around guests’ rooms to find it – a waste of time and valuable resources.” Anacove AI cloud brain The performance of all four Anacove technology services (thermostats, toilet leaks, staff and asset trackers) are monitored and analyzed by the company’s AI cloud system, effectively a brain hovering over key operational areas of the hotel that make intelligent decisions. This ‘Anacove AI cloud brain’ – the only system of its kind – looks at the whole hotel as a single living entity, autogenerating reports that allow hoteliers to clearly see the return on their investment. The AI-enabled, cloud-connected energy management solution uses one inclusive dashboard, with a data-rich, monthly ‘flash report’ that provides a summary of how much energy has been saved, what's going on in terms of potential toilet leakage, etc. Easy and energy efficient Overall, Saju is delighted with not only Anacove’s innovative, unique, AI-powered, cloud-connected devices, which are exceeding Anacove’s own expectations, but also by the company’s service and support. “They advertised a saving of about $12.00 per-room per month for the Smart Thermostats, which was pretty significant, but we're beating those numbers,” he explained. “Overall, all their technology is easy to install and use. There are huge savings, and – importantly – our general managers are very happy!” “Anacove’s after-sales service has also been second to none, and they have been incredibly receptive in helping us adapt the systems to our own requirements. I am a huge fan of Anacove and the team there; they're good people and I'm so glad that we're able to work together.”

Users can calculate their carbon emissions using Wren’s intuitive calculator and fund various climate projects, including refrigerant destruction. Wren emphasizes transparency by providing regular updates on the impact of contributions, including data, photos, and stories. The platform aims to make climate action simple and effective, ensuring that every dollar contributes to meaningful environmental change. About A-Gas A‑Gas is a world pioneer in the supply and lifecycle management of refrigerants and associated products and services. Through the first-class recovery, reclamation, and repurposing processes, we capture refrigerants and fire protection gases for future re-use or safe destruction, preventing harmful release into the atmosphere. For over 30 years, A-Gas has supported clients and partners on their environmental journey by supplying lower global warming gases and actively increasing the circularity of the industries we serve, building a sustainable future. Challenge HCFC-22 is a potent greenhouse gas with a global warming potential (GWP) much higher than CO2 The widespread use of refrigerants like HCFC-22 (R22) presents a significant environmental challenge. HCFC-22 is a potent greenhouse gas with a global warming potential (GWP) much higher than CO2 (one molecule of R22 has a global warming impact 1,810 times that of one molecule of CO2). If not properly managed, its release would have a negative impact on the atmosphere. As these refrigerants reach the end of their lifecycle, there is an urgent need for effective solutions to prevent their emissions and minimize their environmental impact. Solution To address this challenge, A-Gas recovers refrigerants for reclamation or destruction at A-Gas facilities across the country. By leveraging Wren's platform to mobilize individual contributions and A-Gas' technical expertise in lifecycle refrigerant management, this partnership enabled an environmentally conscious solution for the used refrigerant. It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry through its on-site refrigerant recovery service (Rapid Recovery®), refrigerant buyback programs, and wholesale supplier reclaim program (Refri-Claim™). HCFC-22 destruction project The ACR methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017 Wren and A-Gas formed a partnership to provide Wren subscribers with the opportunity to fund an HCFC-22 destruction project through the generation of A-Gas carbon credits to ensure the gas does not escape into the atmosphere. While the ACR (formerly American Carbon Registry) methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017, few have completed such projects because the price of HCFC-22 is so high; it is more profitable for organizations to reclaim this product. ACR’s methodology As such, this is one of the first HCFC-22 destruction projects utilizing ACR’s methodology. Approved by the International Civil Aviation Organization (ICAO) to provide carbon credits in its Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), ACR is highly regarded across the world. Results The partnership yielded multiple environmental benefits: Emissions Avoided: The initiative successfully avoided the release of 16,000 tons of CO2-equivalent emissions by destroying HCFC-22. This substantial elimination of greenhouse gas emissions demonstrates the effectiveness of the program. Subscriber Engagement: Wren provided its subscribers with detailed updates on the impact of their contributions. These updates included data on the quantities of HCFC-22 destroyed and the corresponding emissions reductions. This transparency helped build trust and encouraged ongoing participation in climate action. Educational Impact: The collaboration raised awareness about the importance of proper lifecycle refrigerant management. Wren and A-Gas educated the public on lesser-known aspects of climate change mitigation by highlighting the environmental benefits of destroying high-GWP substances. Conclusion This partnership enabled an environmentally conscious solution for the used refrigerant By leveraging Wren's platform to mobilize individual contributions and A-Gas' technical expertise in lifecycle refrigerant management, this partnership enabled an environmentally conscious solution for the used refrigerant. It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry. refrigerant destruction protocols and technology "We are excited to work with A-Gas to push forward the standard of refrigerant destruction protocols and technology," said Landon Brand, CEO, of Wren. Landon Brand adds, "This is one of the most reliable and impactful project types we have found in our years of funding climate solutions, and we hope our community can keep blazing a trail to eliminate these dangerous refrigerants."
The Olsen Group, based in Boca Raton, Florida, is a national pioneer in HVAC energy optimization. Donald Olsen and his seasoned team of HVAC control specialists have been in business for two decades, integrating energy-saving solutions into over a thousand commercial and large-scale residential projects. In the process, the Olsen Group has become one of North America’s top suppliers of Verdant thermostats. Verdant devices leverage intelligent occupancy sensors and proprietary software to reduce HVAC runtimes by 45 percent on average. HVAC control integration Verdant’s effectiveness, reliability, and broad compatibility have made Verdant the energy management solution of choice for thousands of hotels and MDUs, including multifamily buildings, senior living, and student housing. The Olsen Group has forged a productive two-way partnership with Verdant. Donald Olsen and his team have made it a priority to share data, customer feedback, and requirements with Verdant – and Verdant, in turn, has come to rely on Olsen when they need to field test a new solution. In May of 2024, Verdant reached out to Olsen for help with a new pilot program aiming to facilitate more effective HVAC control integration, easier service, and deep energy savings for MDU projects around the globe. The Challenge Commercial VRF systems have an extremely attractive set of upsides for hotel operators Inverter (VRF) system design is becoming increasingly common in hospitality settings. Commercial VRF systems have an extremely attractive set of upsides for hotel operators. They are significantly more energy efficient and quieter than traditional VTACs or PTACs; they can provide simultaneous heating and cooling to different zones for optimal guest comfort; and they allow both individual room-level setpoint control and building-level centralized management. However, the majority of VRF units cannot connect directly to a third-party smart thermostat. Because they rely on proprietary manufacturer protocols for variable speed commands and internal diagnostics, VRF units require an external control solution to facilitate bidirectional communication with Verdant thermostats. Installation and commissioning process Every additional component in a system adds complexity and opportunity for human error. In hotels, that complexity is multiplied across hundreds of rooms. “HVAC systems are installed dark for new builds, with no power running to the site,” says Donald Olsen, President and Owner of the Olsen Group. “There’s no way to test as we go. If there are any mistakes during installation, we find out about it when the lights go on after project completion.” And mistakes are nearly inevitable. Some third-party controllers have prominent dipswitches that can be easily snagged or tripped during transportation or installation, altering their configuration and causing them to fail once the system is powered. These switches are often accidentally tripped multiple times throughout the installation and commissioning process, pioneering to a never-ending cycle of errors and service calls. VRF control solutions Adding to the issue, not all third-party control keys have the ability to retrieve and solve system error codes “Once properly configured and installed, VRF control solutions tend to be incredibly reliable,” says Olsen. “Getting them there is a real challenge, however. Accidents, human error, and repeated recalibrations can drive serious project overruns and client dissatisfaction.” Adding to the problem, not all third-party control solutions have the capability to retrieve and translate system error codes. “If the central management system isn’t getting certified manufacturer control signals from the control device, it may no longer recognize the thermostat. The system will continue to function, but it will always show up in the central manager with an error message,” warns Olsen. Airzone Aidoo Pro control solution These false error reports degrade the overall utility of the central management system, robbing operators of the ability to detect and mitigate problems proactively and requiring onsite testing to diagnose any issues. As VRF systems become the norm for hospitality projects, Verdant needed a solution to reduce the possibility of accidental misconfiguration and improve visibility into system functionality. They called on Olsen to conduct a pilot program, retrofitting sixteen VRF units in the Jacksonville Beach, FL Springhill Suites with the Airzone Aidoo Pro control solution. The Solution For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller The Jacksonville Beach Springhill Suites is a 156-room hotel with a state-of-the-art Daikin VRV rooftop chiller system. The Airzone Aidoo Pro ships preconfigured for the specific HVAC unit model, reducing the possibility for errors during initial installation. For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller. This 1:1 system design simplifies operations and troubleshooting: Any issue can be immediately traced back to a single unit, minimizing the scope and duration or repair downtime. “The Airzone Aidoo Pro offered two key upgrades as a VRV control solution,” says Olsen. “First, the dipswitches are recessed, making them much harder to trip accidentally. Second, Aidoo makes the system much easier to service. We can read error codes, run tests, and diagnose issues remotely, without ever needing to disrupt a guest’s stay.” Airzone’s expansive library This advanced remote management is enabled by Airzone’s expansive library of manufacturer protocols. “Because of our close relationship with HVAC manufacturers, Aidoo Pro can provide the proprietary control signals the central management system is expecting to see,” says Borja Fernandez, Director of OEM Solutions, Airzone. “That preserves all the features of the HVAC unit and thermostat, while also eliminating persistent false error codes. With Aidoo Pro, the central management system can function as a single-pane-of-glass HVAC monitoring and control solution for the building, as intended.” Results and Next Steps The pilot program is expanding to new builds around the globe, including projects in the UK Olsen reports that Springhill Suites is happy with their upgraded VRV system. “They have more visibility into the system and fewer services calls,” says Olsen. “When there is an issue, we can diagnose it remotely for faster resolution and less guest room downtime. It’s a much better customer experience overall.” Verdant is encouraged as well. This pilot program is expanding to several new builds around the globe, including projects in Central America, the Caribbean, the UK, and the EU. HVAC energy savings “There is a massive untapped market for energy-efficient HVAC upgrades in the Caribbean region,” says Olsen. “Energy costs there can exceed a dollar per kilowatt hour. Cost-effective devices like Verdant thermostats and the Airzone Aidoo Pro pay for themselves very easily in that scenario.” Verdant and the Olsen Group have built global brands by helping commercial properties realize significant HVAC energy savings. Through the Airzone Aidoo Pro pilot program, they are continuing to innovate, enabling reliable integration and enterprise-grade control on highly efficient VRF units. “The demand for commercial VRF control is definitely there,” says Olsen. “With Verdant and Airzone, we can deliver it with ease.”
With a reputation for uncompromising integrity, HDG Legacy is an experienced voice in the hospitality industry for those looking to build, own, and operate hotels. As both a respected developer and preferred management company, the Legacy team employs its core values of teamwork, communication, innovation, leadership and resourcefulness, and has an established reputation for positively impacting the hospitality sector. Currently, Legacy manages and maintains nine hotels that it owns, with its tenth opening July 2025. Rising energy and water costs A commitment to improving and innovating hotels means that Legacy is alive to the economic challenges facing hoteliers, not least in operational challenges because of rising energy and water costs. With profit margins often razor-thin, even small innovations can mean the difference between profit and loss, so it was no surprise that Legacy looked to Anacove’s unique AI- and Cloud-powered Smart Thermostats, Leak Detection and Asset Management systems to help give its hotel clients the edge in their energy and water management. Anacove’s Smart Thermostats “One of my core beliefs is that operating a business that respects the environment in terms of how resources are utilized is important just because that's the right thing to do – but there's also an economic benefit,” explained Navroz F. Saju, Founder and Principal at HDG Legacy. “We initially tested Anacove’s Smart Thermostats across our express properties, before piloting them in one of our larger hotels, and we were so impressed with the results (we actually have the data showing the savings for 2024-25 thus far – very impressive!) that we are looking to roll out the solutions across our other properties.” Electricity consumption reduced He continued, “We started using Anacove Smart Thermostats in July 2024 at the Holiday Inn Express Crystal River, and based on historical data and usage, electricity costs on our utility bills are 35.94% lower per occupied room.” “The Holiday Inn Express & Suites Silver Springs-Ocala’s electricity costs were 33% less than what we’d budgeted for per room, with the Holiday Inn Express & Suites Inverness-Lecanto coming in at 43% lower than budgeted in electricity usage.” Features of Smart Thermostats Anacove’s Smart Thermostats are innovative IoT devices with advanced sensors Anacove’s Smart Thermostats are innovative IoT devices with advanced sensors that monitor temperature, humidity, air quality, barometric pressure, current weather conditions, daylight conditions and guest presence. They seamlessly integrate with HVAC systems through existing hotel WiFi infrastructure, allowing for centralized control throughout the hotel. This enables continuous optimization of each room, regardless of occupancy status, leading to immediate and sustained cost savings. Unlike other occupancy-sensing thermostats, Anacove Smart Thermostats remain active even when guests are asleep or have left their pet in the room. Optimizing HVAC Cycles Learning from each room’s thermal behavior – heating and cooling coefficients – the thermostats optimize HVAC cycles, resulting in reduced peak energy consumption, and maintenance of guest comfort with less energy usage. “I have been very pleased with the transition to Anacove Smart Thermostats, and we will continue to replace older, less efficient thermostat technology with Anacove thermostats,” added Saju. “They are easier to operate – for staff and guests – and install than others on the market – irrespective of their superior energy-saving performance – and are incredibly responsive.” Anacove’s staff and support Such was their ease of use that Legacy’s skilled maintenance staff installed the Anacove Smart Thermostats themselves, but Saju is keen to point out how engaging Anacove was throughout the process. “Their support has been excellent. Even though the thermostats are easy to install and operate, if there is ever a question that needs answering the Anacove team is there to back us up very quickly and in a very expert way,” he said. “I've been very comfortable with their price point – I actually think that their thermostat pricing is the most competitive I have found – and with their after sales service and the technology’s ease of use they are very customer-centric indeed.” Anacove’s AI-enabled water management systems In addition to rolling out Anacove’s Smart Thermostats incrementally across his hotels, Saju is also deploying the company’s AI-powered, cloud-maintained Toilet Leak Detectors and Asset Tracking Systems. The AI-enabled water management systems go beyond basic leak detection. While sensors installed in water tanks or behind walls detect even the tiniest leaks, it’s the AI that identifies anomalies, pinpoints problem areas, and alerts maintenance teams before the issue escalates – saving water, money, repair costs, and mitigating guest inconvenience. Anacove’s Asset Management System Anacove’s Asset Management System equips hotel assets such as luggage carts, rollaway beds, cribs, housekeeping trollies and other movable items with location tags, which, thanks to the cloud-maintained AI system, helps to track down missing items, triangulating their exact positions, streamlining retrieval, reducing loss, and improving overall resource management. “We all expect a lot from our hotel’s front desk,” said Saju. “They’ve got to check people in, the phone's ringing, someone wants a bandage and then suddenly someone will check in and say, ‘where's the luggage cart?’” “The fact that they're immediately able to log in to the Anacove cloud dashboard on their phone and see exactly where the cart is – usually in a guest’s room – is an incredible time-saving benefit, enabling them to locate the cart’s exact location so that they can repurpose the cart for another guest’s use. In the past they would have to ring around guests’ rooms to find it – a waste of time and valuable resources.” Anacove AI cloud brain The performance of all four Anacove technology services (thermostats, toilet leaks, staff and asset trackers) are monitored and analyzed by the company’s AI cloud system, effectively a brain hovering over key operational areas of the hotel that make intelligent decisions. This ‘Anacove AI cloud brain’ – the only system of its kind – looks at the whole hotel as a single living entity, autogenerating reports that allow hoteliers to clearly see the return on their investment. The AI-enabled, cloud-connected energy management solution uses one inclusive dashboard, with a data-rich, monthly ‘flash report’ that provides a summary of how much energy has been saved, what's going on in terms of potential toilet leakage, etc. Easy and energy efficient Overall, Saju is delighted with not only Anacove’s innovative, unique, AI-powered, cloud-connected devices, which are exceeding Anacove’s own expectations, but also by the company’s service and support. “They advertised a saving of about $12.00 per-room per month for the Smart Thermostats, which was pretty significant, but we're beating those numbers,” he explained. “Overall, all their technology is easy to install and use. There are huge savings, and – importantly – our general managers are very happy!” “Anacove’s after-sales service has also been second to none, and they have been incredibly receptive in helping us adapt the systems to our own requirements. I am a huge fan of Anacove and the team there; they're good people and I'm so glad that we're able to work together.”
