Meeting a project’s overarching design goals is vital in the building and construction sector. Creating a sustainable building could be one of these goals — driven by company commitments, federal policies, and state-based initiatives. However, the priorities of minimizing capital and long-term operating costs and maintaining project timelines often prevail.  Frequently, the perception in the industry is that these priorities — especially cost — are incompatible with designs and technologies that help decarbonize buildings. Cutting emissions and optimizing costs Organizations can take an incremental approach without compromising on cost However, our experience with heating, ventilation and air-conditioning (HVAC) systems has shown that cutting emissions and optimizing costs are not mutually exclusive when we leverage the right technologies and design strategies. Decarbonization isn't a one-time event. Reducing emissions is a continuous process with many paths. Organizations can take an incremental approach without compromising on cost. Finding the right balance requires weighing project priorities, the building’s environment, short- and long-range facility plans and available technology solutions. To achieve this balance, energy modeling is an essential tool. Weighing up design goals When it comes to sustainability and decarbonization in HVAC systems, there are three primary levers: electrification of heating using heat pumps, improving energy efficiency and using lower global warming potential (GWP) refrigerants. Cost priorities can often be aligned more easily with sustainability goals than expected Each project's physical environment and framework conditions will influence the mix of these three levers. Cost priorities can often be aligned more easily with sustainability goals than expected. For example, the local climate substantially impacts electrification.  In hotter climates, electrification is far easier than in cold ones, where heat pumps require much more electricity when heating. In extreme cold temperatures, heat pumps will eventually require a back-up like natural gas (NG) to provide supplemental heat. A hybrid system using NG as a back-up to the heat pump also avoids oversizing the heat pump to cope with the most extreme conditions – which only occur infrequently. Hybrid heating systems come into their own Hybrid systems can significantly reduce emissions compared to traditional fossil-fuel-only heating systems and save costs, especially in areas with access to cheap renewable electricity from solar PV plants, wind farms and hydro or geothermal sources. By switching over to NG when temperatures get too low or when insufficient renewable electricity is available, building owners can not only save costs but also hedge against grid outages in the coldest months of the year. It’s critical to pick the right point for your hybrid system to switch from one fuel source to another. By changing to the lowest rate — electricity or gas prices — at any particular time, you can save money while making significant CO2 savings. Alternatively, the time to switch could be based not only on energy costs but also on emissions reductions, allowing the designer to optimize around different design goals. Sustainability doesn’t necessarily command a premium A study from the National Renewable Energy Laboratory demonstrates that decarbonization and broader sustainability goals can be achieved alongside other design goals. When comparing conventional school buildings with zero-energy schools — buildings that produce as much renewable energy as they need to operate — the NREL found that the latter offers several benefits. Zero-energy schools require less energy and offset demand using on-site renewable energy. Zero-energy schools require less energy and offset demand using on-site renewable energy The study indicates that zero-energy school buildings can be designed and built within conventional budgets — and they can cost less. By applying an integrated approach to design and construction, the extra cost of the zero-energy systems can be offset by the greater efficiencies they facilitate. The study lists downsizing heating, ventilation and air conditioning among the benefits that help reduce capital and operational expenditures. However, as we have seen, balancing each building's inherent complexities is the key to achieving these benefits. This is where energy modeling comes into play. Balancing sustainability and design goals Energy models tie together all factors affecting HVAC design and installation. They are a tool for comparing many design alternatives quickly and cost-effectively to find the most appropriate solution to the project’s design goals.  Energy modeling can simulate various system configurations to show the effect of using different types of equipment, such as an electric heat pump compared to a conventional HVAC system. Modeling can also factor in decarbonization policy incentives that may affect the economics and viability of a proposed system. Various system-design options In addition, life-cycle analyses of different keys can provide a clearer long-term financial picture In addition, life-cycle analyses of different solutions can provide a clearer long-term financial picture. Models can forecast long-term costs, performance and return on investment of various system-design options, which can make it easier to get sign-off projects from investors. With its data-driven approach, energy modeling can also prevent overengineering that could lead to unnecessary expenses. A US Department of Energy study has shown that projects using energy modeling perform better and can have shorter returns on investment than those that don’t. The future of HVAC: A harmonized approach As sustainability codes, standards and regulations evolve throughout the US, energy modeling becomes increasingly vital for harmonizing environmental priorities with core design objectives — enabling balanced, effective solutions that drive greener, more resilient outcomes for buildings, businesses and the planet. By integrated advanced modeling practices into the design process, the HVAC industry can support the transition to a low-carbon future without sacrificing economic feasibility or operational efficiency. HVAC industry can support the transition to a low-carbon future without sacrificing economic feasibility. Example analysis A 54,000 ft² office building prototype, compliant with ASHRAE 90.1 standards, was modeled in Denver, Colorado, using Daikin Applied EA Pro software, powered by the US DOE’s EnergyPlus simulation engine. Rebel® heat pump rooftop units were assigned to serve the building. Two HVAC alternatives were analyzed for the heat pumps: (1) electric back-up and (2) gas back-up. The Environmental Protection Agency’s eGRID emission factors, representing the greater Denver regional grid, were used to calculate emissions, along with average electricity and gas utility rates for the region. Electric back-up scenario The results indicate that while total energy usage is lower with the electric back-up scenario—due to the higher efficiency of electric resistance heating compared to gas combustion—the annual utility costs and equivalent carbon emissions are lower with the gas back-up scenario. This is primarily because of higher electric utility rates and the electric emissions profile of the regional electric grid. The annual utility costs and equivalent carbon emissions. This example represents a specific scenario for demonstration purposes but highlights the importance of holistic, project-specific considerations when evaluating design alternatives to meet customer goals.

The HVAC industry stands at a critical juncture, facing substantial regulatory pressures aimed at reducing its environmental impact through the phased elimination of high Global Warming Potential (GWP) refrigerants. Driven by international agreements and local environmental guidelines, manufacturers, suppliers, and service providers are swiftly transitioning towards more sustainable alternatives. This shift is fundamentally reshaping compressor technologies, retrofitting procedures, and lifecycle management strategies for HVAC systems. Newer refrigerants Refrigerants such as R410A, widely used for decades, are rapidly being replaced by alternatives Globally, regulatory bodies like the U.S. Environmental Protection Agency (EPA), the European Union's F-Gas Regulation, and international environmental protocols, such as the Kigali Amendment to the Montreal Protocol, mandate a significant reduction in refrigerants with high GWPs. Refrigerants such as R410A, widely used for decades, are rapidly being replaced by alternatives like R32 and R454B, recognized for their markedly lower environmental impact. These newer refrigerants are not only less environmentally impactful, but they are also in increasingly high demand because of their role in meeting regulatory compliance. Adapting Compressor Technologies For HVAC companies, adapting to these changes requires significant investment and strategic planning. Compressor technology is a critical area demanding immediate attention, as the chemical properties of low-GWP refrigerants differ substantially from traditional refrigerants. To effectively utilize these new refrigerants, compressors must be meticulously redesigned or swapped out for a new system, to ensure system efficiency and performance is maintained. Industry best practices recommend thorough evaluations of compressor efficiency, reliability, and compatibility with the new refrigerants. Companies are encouraged to prioritize high-quality compressors, sophisticated electronics like Printed Circuit Boards (PCBs), and precisely calibrated controls that optimize energy consumption and cooling efficiency. The goal is to achieve a sustainable balance among affordability, performance, and environmental responsibility. Transitioning existing HVAC systems Industry pioneers advocate for wide technician training programs as an vital strategy Transitioning existing HVAC systems introduces significant complexities, as retrofitting requires substantial modifications to components, controls, and infrastructure. The retrofit process can be both technically challenging and costly. Industry pioneers advocate for comprehensive technician training programs as an essential strategy for managing these challenges. Such programs empower HVAC professionals with critical knowledge about refrigerant handling, retrofitting techniques, and adherence to new standards. Participating in robust training programs and utilizing essential tools—such as manifold gauges, refrigerant recovery tanks, and adapters—is vital for facilitating a smooth transition industry-wide. Those looking to get ahead should also look to partner with a targeted consultation and technical support services, helping businesses evaluate specific needs and make informed decisions about retrofits. This personalized approach significantly enhances the likelihood of successful system upgrades and regulatory compliance. Comprehensive Lifecycle Management Sustainability extends well beyond refrigerant selection, encompassing all aspects of HVAC system management—from manufacturing to end-of-life disposal. Partnering with HVAC suppliers that have obtained certifications such as Energy Star and AHRI guarantees the products meet stringent standards for energy efficiency, reliability, and environmental performance. Companies are increasingly adopting sustainable manufacturing practices, including the use of recycled materials, reducing waste during production, and minimizing carbon emissions through efficient manufacturing processes. Effective lifecycle management also involves proactive maintenance strategies that extend the operational life of HVAC systems, minimizing the frequency and scale of necessary replacements. Partner with certified recycling facilities Companies can partner with certified recycling facilities to ensure the proper handling and disposal Furthermore, readily accessible replacement parts ensure rapid repairs, reducing downtime and preventing premature system disposal. Proactively managing refrigerant supplies, including responsible storage and accurate tracking of refrigerant usage, prevents leaks and reduces emissions.  At the system’s end-of-life, promoting responsible recycling practices for components like compressors, coils, and electronics significantly minimizes environmental impact. Companies can partner with certified recycling facilities to ensure the proper handling and disposal of these materials, further driving towards holistic compliance with sustainability standards. Importance of proactive preparedness and agility Historical shifts, like the transition from R22 to R410A, have highlighted the importance of proactive preparedness and agility. Companies anticipating regulatory changes and proactively adapting their processes and products are better positioned to lead and provide compliant, reliable solutions. Such proactive measures demonstrate the value of having the necessary tools, resources, and training well-established before further regulations take effect.

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.

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.”
