West Africa Water Expo: 7th International Water & Waste Water Exhibition, which is organized by Elan Expo, will be held on 20-22 May 2025 at Landmark Center in Lagos, Nigeria. Improved water sources Nigeria is one of the biggest countries in Africa with its increasing population and annual GDP rates. With the increase in the population, the urbanization process is speeding and the local people have low-level access to improved water sources and sanitation. Wastewater Management in Lagos State as the case in other parts of Nigeria is minimal, with only a fraction of wastewater being treated. Sanitation systems currently used in Lagos State include both government and private facilities. The government cannot afford to fill the gap that exists between the current capacity of the state water corporations and the required daily volume for the state’s use. According to the government, the private sector is thus encouraged to invest in the sector. Wastewater treatment facilities The General Manager of ELAN EXPO, Mr. Suer Ay illustrates his opinions about the Nigerian Water industry as; "Nigeria is not a water-poor country, it needs more investments. Nigeria produces 1800 m3 of water per capita annually; there are enough water resources for domestic, industrial, agricultural, hydropower, transportation, and recreational uses but there is more need for modern wastewater treatment facilities during the rapid urbanization process." Mr. Suer Ay adds, "In this year's Wawe Expo 2024, we served the local people to meet international suppliers for Water And Waste Water Treatment, Transport & Storage, Process Control & Automation, Engineering, And Flood Control/Storm Water."

Expert Commentary
It’s often said the only constant in life is change. In the HVACR industry, that phrase has been especially true. We saw another year of transitions in 2024 that included evolving efficiency and refrigerant regulations, changing corporate net zero targets, the continued emergence of advanced heat pumps, and the impact of artificial intelligence (AI) in building management. Smart and sustainable Throughout these transformations, the industry continues to overcome challenges and innovate as we transform the places where people live, work, and play into smarter, healthier, and more sustainable spaces. As we look toward 2025, we can expect to see a continued, industrywide focus on decarbonization, heat pump development, A2L refrigerants, and AI as regulations expand and new technologies emerge. Decarbonization Decarbonization continues to be a very high priority for both the residential and commercial sectors Decarbonization continues to be a very high priority for both the residential and commercial sectors. This focus has transformed the way we design and install HVAC equipment and has created tremendous opportunities for those who invest in educating themselves on the evolving technologies, regulations, and incentives. Today’s building professionals and homeowners have an unprecedented number of incentives available at the federal, state, and utility levels encouraging decarbonization transitions. Digital and net zero services For example, tax credits such as 25C for consumers and 179D for commercial building owners were expanded under the Inflation Reduction Act (IRA) and can significantly reduce the upfront costs of high-efficiency equipment, creating a compelling offer to replace less efficient systems. In commercial buildings, combining high-efficiency HVAC equipment like electric heat pumps with digital technologies and net zero services can help empower organizations to optimize their buildings and subsystems for both the short- and long-term. Heat pumps Heat pump technology has advanced significantly in recent years, providing an electrified, high-efficiency HVAC option for nearly all applications – even those operating within colder climates. The Department of Energy’s (DOE) Residential Cold Climate Heat Pump (CCHP) Technology Challenge has propelled the successful introduction of heat pump prototypes that can withstand subfreezing weather. Similarly, the DOE’s Commercial Building Rooftop Heat Pump Accelerator program has helped drive packaged heat pump performance toward greater efficiency for commercial and light commercial buildings located in colder climate zones. Water-to-water heat pumps Water-to-water heat pumps can replace legacy chiller and boiler combinations without the need for major changes Innovations in commercial water-to-water compound centrifugal heat pumps are also accelerating decarbonization within building retrofits. For facilities that require simultaneous heating and cooling, such as hospitals and universities, water-to-water heat pumps can replace legacy chiller and boiler combinations without the need for major changes to the existing HVAC infrastructure. This partial decarbonization approach can help building operators achieve their decarbonization goals while also lowering operational expenses (OpEx). In many instances, this reduction in OpEx also provides a path to funding additional decarbonization strategies. A2L refrigerants The EPA continues to make strides in reducing the consumption and production of hydrofluorocarbons (HFCs) under the American Innovation and Manufacturing (AIM) Act. As part of the AIM Act, the Technology Transitions Program will usher in sector-based regulations beginning January 1, 2025, prohibiting the manufacturing of equipment using refrigerants with a GWP higher than 700. New protocols As a result, new equipment will continue to hit the market throughout 2025. In tandem, many contractors and technicians will begin working with A2L refrigerants for the first time. Because these refrigerants are classified by ASHRAE as mildly flammable, new protocols for safe refrigerant servicing, storage, and transportation, and refrigerant leak detection (RDS) requirements will be necessary for some applications. ACCA A2L refrigerant training Contractors should complete ACCA A2L refrigerant training and EPA section 608 certification With these changes, it is important to become familiar with updated codes, including UL 60335-2-40, 3rd and 4th editions, ASHRAE 15 and 15.,2, and the AHRI Safe Refrigerant Transition Task Force (SRTTF), as well as local and state regulations. Contractors should also complete ACCA A2L refrigerant training and EPA section 608 certification. Additionally, new digital tools such as RDS calculators can help contractors navigate A2L leak detection requirements and mitigation strategies while in the field. AI and controls AI is positioned to continue to make a huge impact in HVAC. We’re seeing more service techs using generative AI and co-pilots for troubleshooting rather than paging through manuals. At the same time, AI technology can predict if connected HVAC units may have issues, making it possible for service techs to address potential issues in their earliest stages or prevent them from happening altogether. Both of these use cases can help technicians service equipment more quickly, efficiently, and accurately, which can increase equipment longevity and reliability while reducing downtime and total cost of ownership. Building performance AI-powered building controls can provide a holistic view into contextualized, full-building performance More HVAC systems are being equipped with AI-enhanced controls and reporting. The capabilities these tools provide can give building owners greater opportunities to optimize building performance, improve occupant comfort and well-being, and more easily reach sustainability targets. From a building management perspective, AI-powered building controls can provide a holistic view into contextualized, full-building performance, occupant experience, and sustainability. Openness and flexibility As AI becomes more commonplace, AI-centric building standards, such as ASHRAE Guideline 36, will also continue to emerge that balance sustainability with occupant comfort, health, and safety. As we move into 2025, we can expect to see another year of equipment innovations, technology advancements, and evolving regulations. As an industry, we continue to face change with openness and flexibility. And it’s this mindset that empowers us to meet, and exceed, expectations – now and in the year to come.
Devastating wildfires sweep across the US each year, leaving a trail of destruction in their wake. Aside from the immediate damage that fire causes to property and land, the additional impact that wildfire smoke has on air quality creates a serious but often overlooked threat to human health. This threat from poor air quality includes people in the workplace. IAQ management As wildfires increase in frequency and intensity, facility managers must be proactive to protect occupants inside their buildings. This article will explore how facility managers can manage indoor air quality during wildfires, focusing on the role and importance of HVAC systems and continuous IAQ monitoring. Huge Economic Losses to Business and Property The effects of wildfire smoke on air quality also have far-reaching consequences for businesses Wildfires cause massive destruction, with US workers suffering an annual average loss of $125 billion in pay. The broader economic impact is estimated to cost the US between $394 and $893 billion annually. While some of these costs result from direct fire and smoke damage, the effects of wildfire smoke on air quality also have far-reaching consequences for businesses regarding the “knock-on” effects, such as sick days caused by respiratory issues, productivity, and general well-being. Managing indoor air quality to keep building occupants safe, such as office workers, school students, and staff, is therefore becoming an essential part of a facility manager’s job. The Health Risks from Exposure to Wildfire Smoke The Invisible Invaders: Wildfire smoke carries a range of harmful pollutants, including fine particulate matter (PM2.5) and volatile organic compounds (VOCs). These microscopic particles can penetrate the lungs, causing respiratory and cardiovascular problems. As Professor Jeffery Siegel explained in a recent webinar hosted by Airthings, wildfire smoke also contains volatile and semi-volatile compounds and inorganic gas-phase compounds, many of which can pose significant health risks to people, such as eye, nose, and throat irritation, and, in more serious cases, cancers, immune suppressions, reproductive problems, and dementia Beyond the Obvious: The effects of wildfire smoke extend beyond the immediate vicinity of the fire. Smoke can travel hundreds of miles, infiltrating buildings and compromising indoor air quality even in distant areas. The Silent Threat: While staying indoors may seem like a haven, wildfire smoke can easily seep into buildings through windows, doors, and ventilation systems. Without proper IAQ management, the air inside can become as hazardous as the outside air. HVAC Systems: an Essential First Line of Defense Facility and building managers have challenging roles at the best of times When an area is affected by wildfire smoke, properly functioning HVAC systems and their filters, alongside strategies such as automating BMS to close dampers or increase ventilation when PM2.5 levels rise above a certain level, become critical for keeping people inside a building safe. Facility and building managers have challenging roles at the best of times, so how can optimizing HVAC systems support them in keeping building occupants safe during the difficulties posed by wildfires? Continuous IAQ Monitoring: The Key to Informed Action Preparing a building to cope with the risks posed by wildfire smoke is virtually impossible without knowing the baseline of what’s “normal” for your building’s HVAC performance, alongside demonstrating how a building might have performed during a previous wildfire and whether past mitigation strategies worked. Case Study: A customer we spoke to recently realized that their building’s reception area was particularly affected by dangerous levels of PM2.5 during a wildfire due to the simple fact that the outside door was regularly opening and closing. This insight led to targeted interventions, such as installing an air curtain, to improve IAQ in that area. However, IAQ data from deeper inside the building determined that PM2.5 levels were safe, showing that the HVAC system and plan for sealing the building were working. Had PM2.5 levels been high across the building, this would indicate that the HVAC systems were not performing as they should. The customer now knows that their strategy works and can rely on it in the future. IAQ Monitoring: Beyond Pollutant Detection System Performance: IAQ monitors can help assess the effectiveness of HVAC filtration and ventilation systems. By tracking changes in pollutant levels, facility managers can identify areas where additional measures, such as localized air purifiers, may be needed. Occupancy Patterns: Some IAQ monitors also measure occupancy, providing valuable information about which areas of the building are most frequently used. This data can guide ventilation strategies and optimize air quality in occupied spaces. Top Tips for Facility Managers Keeping People Safe During a Wildfire As discussed, facility managers are integral to maintaining safe indoor air during a wildfire. The following are some tips for how facility managers can help keep people safe inside a building during a wildfire: Install Air Quality Monitors: Use IAQ devices that continuously measure PM, VOCs, and CO2. These devices provide real-time and historical data to inform decisions about ventilation and filtration. Understanding indoor air quality conditions allows facility managers to respond promptly to any changes, ensuring that air quality remains within safe limits. Proactively Maintain HVAC Systems: Upgrade or Replace Filters: Use high-efficiency filters, such as HEPA filters, that can capture fine particles and replace them regularly to maintain their effectiveness. Filters should be checked frequently during wildfire season, as they can become clogged with smoke particles more quickly than usual, reducing their effectiveness. Regular maintenance of HVAC systems is crucial to ensure they operate efficiently. Seal Buildings: Ensure that doors, windows, and other openings are properly sealed to prevent outdoor pollutants from entering. Use weather stripping and caulking to seal gaps around doors and windows, and consider installing air curtains in entryways to stop smoke from seeping deeper into a building. Limit Outdoor Air Intake: Adjust HVAC systems to minimize outdoor air intake when smoke levels are high. While fresh air is generally beneficial, it can introduce harmful pollutants into indoor spaces during wildfires. Use recirculation settings in HVAC systems to keep indoor air moving without drawing in contaminated outside air. However, if outdoor air intake is still necessary, ensure that high-efficiency filters that control PM and gaseous chemicals are fitted. Communicate Risks and Actions: Educate building occupants about air quality risks. Clear communication helps alleviate concerns and ensures everyone understands the importance of maintaining IAQ. Provide regular updates on air quality conditions and any changes to building operations. Encourage occupants to participate in IAQ efforts, such as keeping windows closed and reporting any issues with air quality. Conclusion Monitoring IAQ and Proactive Maintenance Key for Protecting People During Wildfires To conclude, ensuring that the air inside a building is safe during a wildfire is essential for protecting people and productivity. An approach that includes proactive HVAC maintenance, continuous IAQ monitoring, and also general preparedness regarding the necessary steps to take during a wildfire is crucial for keeping the people inside a building safe even when the air outside might be compromised.
The HVAC market is forecasted to grow at a projected compound annual growth rate (CAGR) of 3.9%, with a prediction to reach $370 billion by 2030. But in reality, the HVAC and plumbing industry is changing rapidly, with operators facing new challenges like never before. Whether it’s rising costs, the uncertain economy, increasing competition, or the workforce shortage, there’s no doubt the HVAC and plumbing market is evolving. So how do you adapt? That’s the key question. My take is that we can’t predict the future, but we can adjust based on the facts on the field. That’s why now is the time for industry operators to focus on strategies that elevate growth, relationships, and longevity. Here are three ways to tackle today’s market. 1. Diversify Service Offerings With the rising costs of customer acquisition and market competitiveness, it is increasingly challenging to build a successful, resilient trade business by just offering one service — especially if it’s a seasonal specialty. While one-service shops were the norm historically, things have changed in the market. The contractor’s relationship with the customer has never been more valuable, and offering multiple trades allows operators to keep relationships within the four walls of the company – without referring valuable leads (or the potential to lose a customer entirely) to the competition. While one-service shops were the norm historically, things have changed in the market By adding more services to your HVAC and plumbing line-up, you become the one-stop, go-to source for essential home services in your market. For the long-term sustainability of the business, it is crucial to ultimately offer the essential three services: electrical, plumbing/sewer, and HVAC. Additionally, when you provide a variety of services your business will experience less seasonal or cyclical highs & lows because it’s well-rounded, diverse, and, ultimately, healthy. 2. Build Scale through Investment It’s a fact: The home services market is highly fragmented, with over 100,000 contracting businesses active in the United States. It also continues to churn out profits — making it a quality investment for home services investors and private equity sponsors. The fragmented market dynamic is an ideal opportunity for consolidation – and there is more investment capital flowing into the market than ever before. Owners with ambitions to grow can be aggressive with tuck-in acquisitions to offer differentiated services Nationally, scaled Platforms backed by investors or large franchisors service ~20% of the market in a metro area. The benefits of scale are significant: substantial purchasing power (especially on equipment), robust digital/traditional marketing capabilities, programmatic recruiting/training functions, breadth of service offerings, and robust balance sheet to fund growth and investment – just to name a few. However, not every investor is the same. Many employ business practices inconsistent with the culture of founder/owner-backed businesses, which smart entrepreneurs/operators can use to their advantage. Owners with ambitions to grow can be aggressive with tuck-in acquisitions to offer differentiated services and build breadth/new skills in their businesses. Alternatively, businesses struggling to make it on their own or with owners approaching retirement, can partner with larger service providers so they can keep practicing their trade without having to run the day-to-day business – just be careful with selecting the right investor to protect your people and legacy. 3. React in Real Time One thing the HVAC and plumbing industry has proven over the last few years is its resilience – especially for the best operators. No matter what the economic climate is, homeowners still need to protect and stay comfortable in their most valuable asset. That should provide a sense of job security to HVAC and plumbing professionals — but also motivate you to go the extra mile to attract and retain business. Just because the HVAC and plumbing industry has shown signs of being recession-resistant (for now) does not mean it can’t be impacted by the economy. That’s why it’s crucial to manage the business daily – especially pricing and the components of gross margin. The best operators review cost inputs with their teams weekly and adjust mid-month, which ultimately helps the business maintain its health and profitability. As we head into the back half of 2024, it will be interesting to see how the rest of the year plays out for the industry, and I continue to be optimistic about a bounce back after a tough 2023. We will have to wait and see-but with the strategies above, businesses can position for success no matter what happens in the future.

Johnson Controls’ Advanced Development Engineering Center (JADEC) in New Freedom, PA., about 25 miles from Philadelphia, highlights and demonstrates the company’s capabilities related to development, testing and manufacturing. The 357,000-square-foot facility is an advanced engineering and testing facility for water-cooled chillers, air-cooled chillers, air handlers, compressors, and heat pumps. Much of the development in the facility centers on advancements in a critical vertical market for the HVAC industry – data centers. Big challenge Data centers are a big challenge – and a huge opportunity – for the HVAC industry. “You cannot ignore the tremendous growth opportunity in this vertical,” says Todd Grabowski, president, Global Data Center Solutions for Johnson Controls. Unlike other verticals that are more dominant in certain geographic regions, data centers are growing everywhere globally – and at a breathtaking pace. “As a growth company, it is critical that we have solutions to handle the growth and serve the customers in the data center market,” says Grabowski. Performance of various components Testing options at JADEC include testing the performance of various components Testing options at JADEC include the ability to test the performance of various components in a controlled environment that approximates how they will operate in the customer’s real-world setting. There are more than 20 testing labs available at the JADEC campus, covering some 250,000 square feet. “We want everyone to understand the unique position Johnson Controls is in to use our technology and our manufacturing scale to accomplish desired outcomes,” said Grabowski. Non-compressor solution JADEC displays the full breadth of what they offer, including a non-compressor solution using direct evaporative cooling and an air-cooled unit that uses a screw compressor or a magnetic-bearing centrifugal compressor. Also included are various water-cooled chillers. Johnson Controls owns, develops, tests, and manufactures all the compressors on display. Customers are assured of getting a fully engineered and supported solution from Johnson Controls (e.g., no third-party compressors). Johnson Controls owns, develops, tests, and manufactures all the compressors on display. Colocated data centers Grabowski emphasizes that each customer installation has site-specific needs that require unique solutions that Johnson Controls seeks to fulfill. The company works closely with data centers, including those operated by “hyperscalers” such as Amazon, Microsoft, Apple, and Meta, and colocated data centers that rent space and capacity to customers based on their growth and needs. Colocated data centers come in a variety of sizes and types; some of them are operated by companies such as Equinix and NTT. Data center solutions Sustainable methods include the use of refrigerants with ultra-low GWP The sustainability of data center solutions is a bigger issue than ever, given the sheer volume of data centers being built to handle the world’s growing computational needs. Sustainable approaches include the use of refrigerants with ultra-low GWP, and water-free systems that do not require higher costs or create higher demands on a locality’s water infrastructure. Magnetic bearing centrifugal compressors are more energy-efficient because no friction is lost in the compression; also, the equipment is quieter. Impact on global electricity demand “Sustainability has always been an important aspect, and now it is critical in 2024 and beyond,” says Grabowski. Because data centers are huge consumers of energy, they can put more strain on the electricity grid and have a big impact on global electricity demand. Lowering energy usage helps to address the challenge. “We want to contribute to energy efficiency, be good stewards of water, and reduce noise,” says Grabowski. Increasing the challenges are the proliferation of new artificial intelligence (AI) chips, more common in newer data centers, which need more power and create more heat than older chips. Advantages of water cooling The liquid contained in a cold plate on top of the chip is denser than air and accept more transferred heat Closed-loop liquid systems are used to cool individual chips, an application that does not cause a strain on local water supplies. The liquid contained in a cold plate on top of the chip is denser than air and can accept more transferred heat. However, chillers and cooling towers lose water through evaporation and can strain local water supplies. Johnson Controls is researching and testing systems that provide the advantage of water cooling without losing excess water to evaporation. Air-cooled systems In contrast, air-cooled systems can cool chips to a point, but may not provide enough cooling for high-density chips. Johnson Controls provides air-cooled machines up to 600 tons and water-cooled systems up to 4,000-plus tons. “As chip technology evolves, the way you cool, secure and automate the entire data center changes as well,” says Grabowski. “Companies such as Johnson Controls must keep up with evolving trends and provide unique solutions.” As chips become denser from a heat-generation perspective, systems must be optimized from a footprint and energy standpoint. JCI provides air-cooled machines up to 600 tons and water-cooled systems up to 4,000-plus tons. Technological solutions “As chip density increases, we will have technological solutions ready for the next generation of chips when they come out,” adds Grabowski. Johnson Controls is also involved in developing new approaches to managing the heat from data centers, such as the possibility of recapturing the heat and circulating it into a district-heating system for a nearby community, university, or hospital. A more widely deployed approach in Europe, the concept of district heating is gaining acceptance in the U.S. market. {##Poll1725623180 - What is the biggest challenge the data center market presents to the HVAC community?##}
SNAP Rule 26 marks an important milestone in the transition from commercial refrigeration to new refrigerants. The rule lists refrigerant substitutes that provide a spectrum of technological solutions to meet required performance, global warming potential (GWP), safety, and environmental standards. SNAP stands for Significant New Alternatives Policy, a program by the U.S. EPA (Environmental Protection Agency) under the Clean Air Act. In general, the program aims to evaluate and regulate substitutes for ozone-depleting substances, considering their overall risks to both human health and the environment. Impact of SNAP Rule 26 Final SNAP Rule 26, Protection of Stratospheric Ozone, lists acceptable substitutes in commercial and industrial refrigeration. SNAP Rule 26 will be effective July 15, 2024. The incorporation by reference of certain material listed in the rule is approved by the Director of the Federal Register as of July 15, 2024. The incorporation by reference of certain material listed in the rule is approved by the Director of the Federal Register “To date, the SNAP program has provided a very effective framework for evaluation and approval in support of innovation and the transition to new technology,” says Andrew Pansulla, Technical Service Engineer, The Chemours Company, a global chemistry company that provides a range of refrigerant products. We asked Pansulla to elaborate further on the impact of SNAP Rule 26 and what lies ahead. Q: How will the Rule’s finalization impact various commercial refrigeration sectors? Pansulla: The rule’s finalization will impact commercial refrigeration in several ways. Areas, where impact will likely be seen, include providing more acceptable refrigerant options, adherence to updated standards, new equipment design standards, and the exemption of propane from the venting prohibition for refrigerated food processing and dispensing equipment. These impacts could trigger changes in operational, manufacturing, and environmental compliance strategies in the commercial refrigeration sectors. SNAP Rule 26 will enable the adoption of the listed substitutes, including Chemours Opteon™ refrigerants, with global warming potential (GWP) lower than existing refrigerants. This rule does not require any changes to existing equipment and will impact only new equipment that uses the specific substances referenced in the SNAP rule. Q: What is the outlook for additional requirements for safe handling and use of alternative refrigerants? What specific safety standards are expected or appropriate? Pansulla: As part of the comparative risk framework used by the EPA to assess new alternatives, the EPA considers and implements use conditions that will ensure the safe use of products. These use conditions rely upon existing safety standards (e.g., UL and ASHRAE) which are available at the time the rule is finalized. In the case of SNAP Rule 26, many of the use conditions require adherence to UL 60335-2-89 and ASHRAE-15-2022. These standards are reviewed and updated periodically to maintain relevance with the products subject to the standards. Q: What are any limitations of the use of A2L refrigerants under SNAP Rule 26? Pansulla: There are two main categories of limitations under SNAP Rule 26. The first, as mentioned above, is the adherence to specific safety standards that apply to refrigerants that are designated as mildly flammable (A2L). The second is based on the GWP of the refrigerant. In the case of the A2L refrigerants subject to SNAP Rule 26, the EPA imposed conditions on the type of equipment and specific circumstances in which the substitute may be used. For example, the EPA is permitting the use of R-454A in supermarket systems, but only on the high side of a cascade system, or when the refrigerant charge capacity is less than 200 pounds. Q: Which new-generation A2L refrigerants are fit for which commercial refrigeration applications? Pansulla: Under SNAP Rule 26, the EPA deems R-1234yf, R-1234ze(E), R-454C, R-455A, R-457A, and R-516A as acceptable subject-to-use conditions for various commercial refrigeration applications. This selection is primarily driven by these refrigerants having GWPs under 150. However, certain applications necessitate refrigerants with higher GWPs due to unique performance characteristics. For example, R-454B and R-32 were listed for industrial process refrigeration with exiting fluid temperatures below minus 30 degree Celsius because these two specific refrigerants have lower boiling points than the other six less-than-150-GWP alternatives. However, it is critically important to consider the additional use conditions when designing equipment with refrigerants that have a GWP greater than 150. Q: So various equipment needs different refrigerants? Pansulla: The EPA purposefully lists several different refrigerants in each application to allow for equipment manufacturers to consider a variety of different factors that go into refrigerant selection, such as energy efficiency, capacity, normal boiling point, temperature glide, cost, safety, and use conditions. There is no one-size-fits-all solution for the entire commercial refrigeration industry. Q: How can commercial refrigeration businesses achieve a smooth transition to A2Ls? Pansulla: Keys to a smooth transition to A2Ls include understanding what refrigerants the EPA has approved as acceptable substitutes under the SNAP program, the sector-based GWP limits imposed by the Technology Transitions Program under the American Innovation and Manufacturing (AIM) Act, and which refrigerants provide the best combination of technical performance and environmental characteristics. Many resources are available to navigate the regulatory landscape and select the best low-GWP refrigerants to meet the needs of this industry. Working with companies like Chemours, who has nearly a century of refrigerant innovation and experience, is a great first step in the transition process. Q: What is the “staying power” of A2Ls — based on their chemistry, sustainability, and other attributes, combined with regulations such as SNAP Rule 26? Pansulla: The identification, selection, and development of new refrigerants that deliver required performance while meeting increasingly stringent environmental standards is a challenging process. With the identification of certain hydrofluoroolefin-based (HFO) refrigerants as an alternative to meet these criteria came a new safety classification. These HFO-based refrigerants are classified as A2Ls. While slightly more flammable than existing hydrofluorocarbon-base (HFC) refrigerants, HFOs are much less flammable than hydrocarbons, which are classified as A3 (two categories higher on the ASHRAE flammability spectrum). Moreover, such refrigerants offer an excellent alternative to substances with higher toxicity, such as R-717. The listing of A2L refrigerants in SNAP Rule 26 clearly indicates that such refrigerants can be used safely in commercial refrigeration as well as many other applications, which are subject to the SNAP Program, when adhering to the applicable safety standards.
Humidity can influence employee health and productivity in the workplace. Humidity, temperature, and ventilation all work in concert to create a healthy indoor environment that supports overall occupant well-being. “Dry indoor air can cause discomfort in the form of dry skin, eyes, and throat for staff and visitors,” says Jennifer Montville, Director of Marketing at DriSteem, a manufacturer of humidification systems. Air-related health issues “There are real costs associated with health-related issues caused by dry air, including a higher occurrence of infections and increased rates of staff absenteeism?” Maintaining a comfortable work environment, including the correct humidity levels, prevents respiratory issues and reduces the spread of illnesses, ensuring a healthy working environment and boosting productivity and efficiency, says Montville. humidity levels Humidified spaces help keep facility costs down by improving thermal comfort at lower temperatures Maintaining humidity levels between 40% and 60% RH is ideal for mitigating virus transmission, she comments. Humidified spaces feel warmer and are more comfortable for employees, which in turn increases their productivity with improved concentration and less fatigue. It also helps keep facility costs down by improving thermal comfort at lower temperatures. dehumidifiers Employing dehumidifiers to keep humidity levels from rising above that 60% RH threshold is also important. Removing excess moisture from the air reduces distraction from unpleasant smells or health issues caused by mold, mildew, or fungi that thrive in moist environments. All the ways that proper humidity levels affect employee health and productivity in the workplace also contribute to increased customer satisfaction in office and retail spaces, says Montville. preventing product issues “We all prefer to spend time in places where we feel physically comfortable,” she says. “Customers in offices and retail spaces are no different. When physical comfort is not an issue, we are likely to spend more time and engage more deeply.” Well-managed humidity levels also help to prevent product issues such as shrinkage, warping, or degradation due to moisture fluctuations. Food quality is particularly impacted by humidity levels. In a retail store, this can translate to spending more time shopping in a store and a more positive opinion of the products being considered. recommended indoor relative humidity level Keeping relative humidity levels within the range ensures the health and safety of building occupants The recommended indoor relative humidity level ranges from 30% to 60% RH, according to guidelines published by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). Keeping relative humidity levels within this range ensures the health and safety of building occupants without promoting mold growth or other indoor air quality issues. air quality goals With that said, the type of indoor space, air quality goals, and how the space is used will determine the best relative humidity levels for each facility, according to Montville. Machinery and sensitive electronic equipment are vulnerable to low or fluctuating moisture levels. Static electricity buildup and electrical malfunctions are among the potential consequences of inadequate humidity control. precise humidity control Many industrial processes depend on the consistent quality of materials, and fluctuations in relative humidity (RH) can result in less-than-ideal inputs which in turn impact the quality of final products. From preventing mold growth, spoilage, and texture deterioration in food processing to safeguarding medication stability, efficacy, and safety of pharmaceuticals, precise humidity control is critical to achieving intended results. Optimal RH levels Adequate humidity also supports the body's natural defense mechanisms, enhancing the effectiveness Maintaining appropriate humidity levels is essential for infection control. Optimal RH levels can inhibit the growth and transmission of airborne pathogens, such as viruses, bacteria, and fungi. Adequate humidity also supports the body's natural defense mechanisms, enhancing the effectiveness of respiratory tract mucous membranes in trapping and neutralizing pathogens. Conversely, dry indoor air impairs these defenses, increasing susceptibility to respiratory infections. humidity control systems Investing in commercial humidity control systems, such as those offered by DriSteem, can effectively regulate RH levels within facilities. “These systems provide flexibility and precision in catering to specific humidity needs across different areas within the facility,” says Montville. Whether integrating humidity control solutions in existing structures or implementing them in new buildings, factors such as the type of indoor space, energy source, required maintenance, and capacity determine the best technology for each building, she says.
Case studies
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.”
In facilities with high volumes of foot traffic, the constant opening and closing of doors not only lets in chilly air but can cause heating problems for the entire building. Cold drafts bring the temperatures down, so while main rooms benefit from the warmth of the building’s primary heating system, many other areas are left to deal with the arctic side effects. Vestibules, lobbies, entranceways, and hallways are frequently populated, so it’s imperative that facilities hunker down and counteract the cold drafts left behind by those entering and leaving buildings. Opt for electric ceiling heaters To help neutralize these blustery winds, facilities should consider fan-forced wall heaters that provide continuous comfort through optimized airflow. Such units are ideal for entryways and other spaces where short bursts of heat are needed – providing a tremendous advantage over gentle heating sources that may not be powerful enough to provide the desired amount of warmth. However, if wall and floor space is minimal, facilities can instead opt for electric ceiling heaters. Mounted flat or recessed to the ceiling, these heaters are ideal not only for entryways but also in conference rooms, waiting areas, bathrooms, and lobbies. No matter the case, both products move heated air with a fan to quickly heat the room from the wall or ceiling. Once the heater turns on, the air is moved over a heating element and circulated into the space, making certain that residents are met with warmth and comfort from the time they enter the building until they leave. Specialized heating units Specialized heating units are designed to stop drafts in their tracks before they laid throughout a building Whether it’s through vents, unsealed windows or cracks and crevices in the building’s foundation, cold air will creep into facilities any way it can. This cool air can make indoor temperatures uncomfortable for occupants and reduce the overall heating efficiency of the facility. Specialized heating units are designed to stop drafts in their tracks before they spread throughout a building. Fan-forced wall and ceiling heaters with an automatic delay feature eliminate cold drafts on start-up and discharge residual heat from the heater body during the shutdown, helping attack drafts at their source, making the best use of available heat and prolonging the life of the heater. Equipped with integrated thermostats To maintain desirable comfort levels, facilities should consider fan-forced wall or ceiling heaters equipped with integrated thermostats or BMS connections for easy adjustment of room temperatures. A hotel’s vestibule, for example, may experience high amounts of foot traffic during check-in and check-out hours. Because fewer people are coming and going outside of these times, the adjustable thermostat feature allows facilities to alter their heating output needs to ensure heat is not misused and temperatures remain comfortable. For commercial fan-forced wall heaters with striking designs and contemporary looks, Berko® and QMark® offer units to match any room’s décor while supplying an appropriate amount of warmth no matter the time of year. Safety First Fan-forced wall or ceiling heaters are built with easily accessible power on/off switches for safety Safety and style go hand-in-hand. While selecting a heater that fits a building’s esthetic is important, opting for a high-quality product that protects against common safety risks should be a top-of-mind priority. Fan-forced wall or ceiling heaters are built with easily accessible power on/off switches for added safety during maintenance. Tamper-proof plugs for thermostat holes prevent unwanted changes to the temperature and keep children and pets from getting into places they shouldn’t. All fan-forced units also come with thermal overheat protectors that disconnect power in the event of accidental dust or debris blockages to mitigate the risk of injury. Additionally, heaters that include permanently lubricated and enclosed fan motors are shown to have longer lives, require less maintenance and gently administer heat throughout a space. Keep in mind that some heaters are noisier than others, so make sure to choose one powerful enough to negate drafts but quiet enough to prevent disturbances from interrupting daily activities. Maintaining Warmth and Comfort Drafts bring cold air and a lasting chill into heated spaces every time a door opens, especially during the colder months. To offset the frigidness, consider installing a fan-forced wall or ceiling heater to regain suitable levels of warmth and comfort for all building occupants. Berko and QMark’s commercial fan-forced wall and ceiling heaters provide the strongest, safest sources of heat for those chilly spaces.
To offset the cost of tenants’ monthly electric bills and provide prospective residents with high-quality HVAC upgrades that prioritize comfort and performance, Samuels Associates, owner of the Fenway Triangle luxury apartments, sought a new, building-wide heating solution that was not only cost-effective but also added a modern touch to the building’s extravagance. QMark® MUH-Pro+ and CU900 electric heaters with SmartSeries® Plus (SSP) digital BACnet thermostats from Goodyear HVAC Sales proved to be the ideal solution. Heat in a contemporary design “From their energy efficiency, quiet operation and low maintenance to the fact that they can be controlled individually for personalized comfort, electric heaters offer several benefits in apartment buildings,” explained Andrew Martin, Manager of Product Management with Marley Engineered Products® (MEP). “Delivering supplemental comfort heat in a contemporary design, these heaters are ideal for a variety of spaces including school hallways, church vestibules, transportation terminals, stairwells, entrances, lobbies, mechanical rooms and more.” Installing Heaters while Maintaining esthetics Buildings boast modern frills and discreet and esthetically good HVAC plans that act quietly Steps away from the iconic Fenway Park, the Fenway Triangle is an 891,000-square-foot complex comprising more than 570 luxury apartment units, as well as an eclectic mix of national and local retailers, restaurants, shops and green spaces. Since opening in 2006, the building needed to address issues with its HVAC systems and controls, which were leading to high monthly electric bills. The culprit? More than 50 outdated competitor electric terminal heaters, which offered only on/off controls and needed to be operated manually. If the maintenance team forgot to shut off the heaters, "The Fenway" would incur the cost of each heater running at full capacity at a rate of about 27 cents per kilowatt-hour. Another challenge facing Fenway Triangle: The emergence of new luxury apartment complexes. These buildings boast modern amenities and discreet and esthetically pleasing HVAC systems that operate quietly. They pose significant competition for “The Fenway”, as tenants increasingly prioritize indoor air quality (IAQ) and HVAC performance when selecting their luxury residences. To remain competitive in the luxury apartment market, investing in HVAC upgrades to replace outdated equipment is imperative. QMark MUH-Pro+ and CU900 electric heaters Heaters were installed in elevator banks, stairwells, worker lounges, hallways, and facility To combat the rising cost of heating each unit within the building, MEP’s local Sales Representative, Goodyear HVAC Sales, worked with HVAC distributor Equipment Direct Sales, Inc. (EDSI) to provide the client with energy-efficient QMark MUH-Pro+ and CU900 electric heaters from Marley Engineered Products. Designed to maintain occupant comfort and a comfortable environment, the heaters were installed in various elevator banks, stairwells, employee lounges, hallways and inside the building’s recently upgraded building management system (BMS) room. “Equipped with SSP digital thermostats that provide connections to BACnet MS/TP BMS for easy control and monitoring, the MUH-Pro+ and CU900 units only run when directed by the internal schedule of the BMS,” said Matthew Goodrich, President of Goodyear HVAC Sales. “Use of the BMS saves time and reduces personnel costs by eliminating the need to travel to the heater site. And, if a BMS is not available, the maintenance team can simply use the built in seven-day programmable scheduling feature.” New electric heating units Cost-Effective Heat for Unmatched Comfort and Lower Monthly Bills In tandem with EDSI, Goodrich and his team installed several brand-new electric heating units in The Fenway’s BMS room to provide cost-effective warmth without taking up floor space or creating a tripping hazard. “Innovation and collaboration converged as we tailored a custom heating solution, seamlessly blending functionality and aesthetics,” explained Goodrich. “In fabricating this solution for the client, our dedicated team and the coordination of skilled contractors transformed this building into a space that harmonizes comfort and elegance and exemplifies the blending of form and function.” Full control of the entire heating system The thermostats include features that allow the building’s maintenance team to monitor each heater The success of the project resulted in an extremely satisfied customer. Already, the SSP thermostats have provided cost savings by turning on the heaters only when needed, resulting in less electricity usage throughout The Fenway. Additionally, the thermostats include features that allow the building’s maintenance team to monitor each heater individually from within the BMS room, granting them full control of the entire heating system and eliminating the daily trips previously needed to turn each heater on and off. “We’re already seeing the savings associated with the upgraded controls,” said John Belmonte, Head of Trilogy Operations for the Fenway Triangle. “Being able to control over 40 heaters locally allows our team to focus on tenant needs without being bogged down by the time it takes to touch each individual unit. We’re eager to work further with the Goodyear team on other buildings in the neighborhood.” Innovative approach and exceptional achievements To acknowledge the innovative approach and exceptional achievements demonstrated by the Goodyear team in overcoming the challenges faced during this project, Marley Engineered Products awarded Goodrich the 2024 Jim Herring Memorial Silver Fox Award at its recent national sales meeting. “This award for excellence in solution design embodies the spirit of Herring, who left a lasting legacy of designing creative solutions for specialized applications, was always up for a challenge and most happy when solving a unique heating or ventilation problem,” said Sean Pesce, Director of Sales for Marley Engineered Products. “Matthew and his team at Goodyear perfectly captured Jim’s talent for finding creative solutions to the most complex issues and left a lasting impression on the client.”
Tucked into the rolling hills of northern Kentucky just 15 miles south of bustling Cincinnati, the city of Independence offers its 28,000 residents access to urban amenities in a picturesque, rural setting. The landscape is dotted with farmhouses, but one 200-year-old home on a sprawling 150-acre property has a unique story. Originally a log cabin in the 1700s, the house has been transformed over the centuries, with structural elements, updates, and modern comforts added along the way. The renovations, including a large expansion in the1920s and a handful of recent modernizations, have kept the home livable throughout the generations. historical integrity with comfort The current owner, Dr. C.J. “Jay” Hellmann, was 6 years old when he moved into the house. His fond memories of growing up on the farm are coupled with memories of sweating through the summer months. With its historic charm and cherished family memories from across the decades, the home means everything to him and his family, who value the farmhouse’s historical integrity but also require modern comfort. Efficient and effective cooling and heating Hellmann focused on making the house more comfortable by finding effective and efficient ways to heat and cool As Hellmann prepared the home for his daughter and son-in-law to move into, he focused on making the house more comfortable by finding effective and efficient ways to heat and cool the living areas. “The family had an oil furnace. They’re very expensive to run, not very efficient, and [produced] dirty air. The next generation moved in and wanted something a little more comfortable and cleaner,” said Josh Williams, Sales Manager, Corken Steel Products. Project highlights The farmhouse had both a rich history and antiquated infrastructure. It was steam-heated by a large, inefficient oil furnace in the basement and did not have ductwork or an air conditioner. Hellmann and his family felt the lack of air conditioning acutely during Kentucky’s humid summer months, which frequently see temperatures over 90°F. The family sought an HVAC solution that would fit their needs without compromising the farmhouse’s historic aesthetic. Inverter technology As the owner of Call Now Heating and Cooling, an Independence-based HVAC contracting business, Hellmann was familiar with LG but hadn’t considered the brand’s inverter technology until he met an LG sales representative at a local event. The two discussed the benefits of heat pump technology and how an LG system could suit the home’s needs. Shortly after, Hellmann scheduled a walkthrough of the house, which helped determine the best comfort solution to condition the home evenly and efficiently while preserving its charm. Quality and availability Hellmann and his team collaborated with Corken Steel and LG to design an energy-efficient solution “I have an HVAC business and I can pick any equipment I want,” he said. “I picked LG for a few reasons, including the quality of the equipment that we looked at, the availability, and that it matched, it looked good in the home. The support from LG was also a key part of my decision.” Hellmann and his team at Call Now Heating and Cooling collaborated with Corken Steel, a ductwork fabricator and HVAC wholesaler, and LG to design an energy-efficient solution that tackled the challenges of bringing modern HVAC products into a coveted older home. Challenges Older homes can pose significant heating and cooling challenges due to inadequate insulation, uneven heat distribution from existing systems, and a lack of ductwork. With traditional systems, this combination of obstacles can lead to expensive and invasive installations where large units take up valuable space. Hellmann sought a solution that would avoid these disruptions and involve fewer adjustments to the home’s footprint and architecture. He found that an all-electric inverter heat pump system from LG addressed all these challenges. Solution The team decided on a whole-home solution using two Multi F Max withLGRED° units to deliver customized comfort to every part of the house. One low-static ducted unit can heat and cool the first level, and six low-wall ductless console units can condition the second floor. After selecting the system, the team began installing it in harmony with the farmhouse’s environment, which required hiding the equipment wherever possible. Together, they determined how to work around steam pipes, where to run lines and drains, the layout of units, and where to place the equipment to maximize airflow. Given the farmhouse’s historic nature, this was not a simple installation; it required the team’s ingenuity and dedication to maintaining the integrity. Refrigerant and power/communication lines The first-floor units use minimal duct runs installed through the floors and into the basement The first-floor units use minimal duct runs installed through the floors and into the basement, where the old boiler system was located. Rather than installing multiple ducted systems for heating and cooling throughout the farmhouse, the team ran refrigerant and power/communication lines discretely through the attic for the low-wall console units in the upstairs rooms and sunroom and utilized an old, unused, laundry chute to run lines into the basement and outdoor units. Comprehensive solution “Our representative from LG made it exceptional to work together. He always answered when we had a question, and if he didn’t know the answer, he told us who to call to get what we needed,” said Brad Helton, HVAC Technician, Call Now Heating and Cooling. The strong relationship between Call Now Heating and Cooling, Corken Steel, and LG made it possible for Corken and Call Now to design a comprehensive solution to fit Hellmann’s needs, streamline installation, and create benefits they hadn’t originally anticipated. Result Ultimately, the team’s main priority was met, the new HVAC system complemented the home’s aesthetic and preserved its historic charm, efficiently heating and cooling. The LG low-wall units’ appearance blended nicely with the farmhouse’s style and their flexibility and small footprints meant they could be placed with consideration for the rooms’ designs. Aesthetics aside, the Hellmann farmhouse reaps many additional benefits from the LG system. The homeowners now enjoy consistent, customized comfort along with reduced noise, improved indoor air quality, and greater energy efficiency. All-electric heating All-electric heating means Hellmann no longer pays for oil to heat the home in Kentucky’s cold winters “The system has better air quality, it’s easier to and the units put out a very hot heat and very cool air compared to a normal heat system,” said Casey Whalen, Installation Manager, Call NowHeating and Cooling. All-electric heating means Hellmann no longer pays for oil to heat the home in Kentucky’s cold winters. This is a significant contributor to energy savings. Zoned comfort control With the old furnace, he’d spent nearly $1,500 every 30-40 days for oil. Now, with the all-electric LG system, he pays about a quarter of that, even in the coldest months. Zoned comfort control offered by the LG system also contributes to energy savings. Using thermostats, remote controls, and smartphone applications, the family can set each zone in their home to a different temperature or even turn units off altogether, depending on the room’s use and occupancy. All-electric LG inverter heat pump “Having a new LG system in this home is very exciting,” shared Hellmann.“We’re able to have cool air in a house that’s 200 years old and has never had cool air before. This was the first summer that you could sit in here and be comfortable, have fresh air, and comfortably use different rooms like the porch. It has made the house more livable, much more useful, and much more comfortable.” Breathing new life into a centuries-old home is a tough task. For the family, the fix has been renovations and modernizations over the years. And Hellman says none stands to benefit the family more or give them a greater return on their investment than the all-electric LG inverter heat pump system.

Water and energy efficiency company Cenergist has been appointed by Ashford Borough Council to provide a nutrient neutrality solution for a new 1,000 home development using its patented Control Flow technologies. The site is within a nutrient-sensitive area that requires any new development to mitigate against increased localized waterway pollution. Cenergist’s patented Control Flow products are pressure-independent flow controllers that provide long-term reductions in water wastage and nutrient emissions from homes as well as improve the performance of existing gas boilers. By eliminating the fluctuations in the water supply caused by system pressure changes, Control Flow provides a steady precise water flow to the home. Control Flow installations By installing in existing homes in the area, Control Flow creates the headroom for new builds Performance tested in both the UK and Europe, Control Flow has been shown to reduce water and energy bills by up to £360 per annum with a 98% customer satisfaction rating. By installing in existing homes in the area, Control Flow creates the headroom for new builds. Under the contract, Cenergist will determine the precise number of Control Flow installations required to offset all the nutrient emissions from the new development at Ashford. Working with the council, it will then contact and persuade householders of the benefits of the technology and then carry and complete the installations and provide the necessary assurance to allow Natural England to sign off on the development. The project follows on from the use of Control Flow to unlock a development in Crawley that had previously been held up due to water scarcity concerns. Nutrient neutrality strategies Paul Mckenner, head of strategic projects at Ashford Borough Council, said: “The retrofitting works is part of a series of measures to unlock approximately 1,000 new dwellings which the Council has a vested interest in.” In England, waterways including lakes, rivers and estuaries are protected under the Conservation of Habitats and Species Regulations 2017. Natural England has mandated that developments located near vulnerable watercourses require nutrient neutrality strategies to prevent negative ecological impact." Caroline Gray Mason, business development director at Cenergist commented: “Nutrient neutrality is a significant challenge facing developers as they look to deliver much-needed housing in a sustainable, responsible way. It is essential to be on the front foot with nutrient mitigation measures to minimize the environmental impact of new developments in vulnerable areas. Securing this contact with Ashford Borough Council is a testament to Control Flow’s role to mitigate nutrient pollution by reducing the level of emissions from existing homes.”
Hospital air handler restoration saves capital budgets for Tampa Bay healthcare facility! This project profile examines how HVAC restoration saves time, money, and energy compared to replacing aging equipment. The Challenge: A large suburban hospital located in Tampa Bay with a 479-bed facility offers comprehensive healthcare services for the region. Recently, SiteLogIQ was working with the hospital on energy/performance surveys to improve facility operations. During the study two air handler units serving Labor and Delivery rooms in The Women’s Center, The Baby Suites were identified as candidates for replacement due to degraded conditions and performance. The Solution: Due to the units’ location inside the penthouse and replacement costs, including time and facility disruption, it was determined that hospital air handler restoration could be done with WTI | Pure Air Control Services HVAC New Life program. Air handler restoration Hospital Air Handler Restoration with HVAC New Life - HVAC New Life is a series of component services conducted over consecutive nights. These phased services effectively cleans, refinishes, and restores performance to an AHU without loss of supply air during normal operating hours. CCV readings were also taken after the cleaning to monitor improvements PURE-Steam AHU and Coil Cleaning - The first step was to HEPA-vacuum the interior of the AHUs. Next, airflow resistance readings were taken across the cooling coils. This is known as a Coil Cleanliness Verification test, or CCV. Second, the interior of the unit was masked off and sanitized with WTI Pure Air’s proprietary PURE-Steam process. This included a deep cleaning of the cooling coils as well. PURE-Steam utilized bio-enzyme treatments and high temperature, low-pressure steam to penetrate through debris that was deeply lodged in the coil. Last, CCV readings were also taken after the cleaning to monitor improvements. In total, this process effectively optimizes AHU performance, cleanliness, and indoor air quality. Air handlers safely High-Performance Coatings - The next step in the hospital air handler restoration process was the refinishing of all the metal components of the units. This included the condensate or 'drain' pans, as well as the exterior. It was done with high-performance, multi-part polyurethane coatings designed and tested for use in HVAC equipment. They are antimicrobial, corrosion resistant, and have a very low odor to extend the useful life of the air handlers safely and effectively. Outside air dampers Outside Air Dampers and Controls - Finally, the AHUs were retrofitted with new outside air dampers which also included upgrades to the control components and system. In conclusion, hospital air handler restoration from WTI | Pure Air Control Services helped SiteLogIQ and the hospital refurbish two AHUs in much less time than replacing and with a significant 76% capital avoidance! Where two brand new AHUs would have cost the hospital $350,000 or more, the hospital saved $266,000 in capital by restoring them with HVAC New life for $84,000. Now the hospital has peace of mind in two restored units with five-year warranties that will provide many more years of service for their patients and staff.
