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.

As demand continues to grow for sustainable, energy-efficient solutions in refrigeration and heating, both Europe and North America are navigating a rapid transition toward natural refrigerants. There is a strong demand for new CO2 systems, including heat pumps and various other applications. Higher capacity compressors with larger operating envelope, such as Danfoss’ Bock HGX56 CO2 T series, will play a critical role in supporting this growing need. Air to water heat pumps As shown in Figure 1 and Figure 2 below, the larger operating envelope of up to 77°F and 65 bar on the suction side can improve the COP by approximately 15% for applications with higher heat source temperatures – for example, air to water heat pumps in summer conditions. Transcritical CO2 figure. Larger operating envelope of up to 77°F and 65 bar on the suction side. Figure 3 below shows a typical layout of a CO2 transcritical air-to-water heat pump for large systems, designed with features to boost efficiency. Such systems are already being built in Europe, with the largest compressor options, and used in heating capacities of up to 2.5 MW per rack. Layout of a CO2 transcritical air-to-water heat pump for large systems. Cooling and Heating Working Together Transcritical supermarket applications with heat reclaim are very suitable for improving the version Transcritical supermarket applications with heat reclaim are very suitable for improving the overall refrigeration system performance. It is a highly efficient and resilient solution that provides simultaneous heating and cooling by recycling waste heat energy within the store. More than 2,000 installations across Europe and in other parts of the world have shown that the traditional CO2 weaknesses in refrigeration applications, such as high temperatures and pressures, can be turned into profitable advantages when adding heat reclaim to the system. In fact, the operational costs can be reduced by more than 20% by replacing conventional heating sources with heat reclaim, and the pay-back time of the heat reclaim installation is typically short, less than 2.5 years. At the same time, huge carbon savings can be made when the system is installed and maintained correctly. Additional Applications Transitioning to CO2 CO2 is increasing in popularity for cold storage and food processing, due to some challenges of using ammonia in states with a large number of regulations, as well as the desire for distributed systems when expanding plants and the advent of larger CO2 compressors. Some estimates show a 10% market transition to CO2 from ammonia and HFCs for systems up to 250 tons (880 kW). An example would be a cold storage facility requiring variable temperatures with stability/efficiency at partial load for garlic processing, storage and pre-cooling. The requirements for pre-cooling are 40°C/39.20°F, but for processing and final storage, −100°C/140°F is required. CO2 System Examples Single-stage transcritical CO2 applications are used in the field of medium temperature refrigeration Single-stage transcritical CO2 applications are used in the field of medium temperature refrigeration. They can be operated very efficiently, if the high pressure is operated in the subcritical range over a long period. Using the high-pressure side, it is appropriate to use the application in the transcritical range in combination with refrigeration, due to a large temperature glide and a relatively high discharge end temperature for specific heat pumps and the heat recovery. In CO2 applications in low and medium temperature refrigeration, so-called booster systems are used. High-pressure CO2 gas from the low-temperature compressor is discharged directly to the suction side of the second compressor stage. Different plant constructions of these Booster applications are used, for example, in supermarket applications. In a cascade system, different refrigerants are used in an application. They are combined in two refrigerating circuits that are separated from each other. The high temperature stage is used as a condenser in the CO2 application. It is possible to use different refrigerants like hydrocarbons, ammonia, and HFCs like R-134A. Keys to a Successful Installation Proper oil levels, adequate space for maintenance and ventilation, environmental conditions and surface setup with sufficient load-bearing capacity are all critical initial items to consider. Once these items have been considered and addressed properly, then you need to take extreme care during the soldering - cooling the valve body during and after and only using inert gas to inhibit oxidation products. The actual required pipe cross-section must be matched to the output. The tube must be sawed at a right angle with the angular tolerance being ±10. Pipes and system components must be clean and dry inside and free of scale, swarf and layers of rust and phosphate. Only use hermetically sealed parts. Lay pipes correctly. Suitable vibration compensators must be provided to prevent pipes being cracked and broken by severe vibrations. Ensure a proper oil return and keep pressure loss to an absolute minimum. Suction and discharge should be depressurized prior to connecting to the refrigerant system. Proper layout of the suction and pressure lines directly after the compressor is integral to the smooth running and vibration behavior of the system. Oil return function To ensure the oil return function will work reliably no matter what kind of system configuration you are using, Danfoss recommends incorporating oil separators or oil level monitoring equipment. For systems with long pipes and higher degree of contamination, a filter on the suction-side is recommended. When attaching accessories with an electrical cable, a minimum bending radius of 3x the cable diameter must be maintained for laying the cable. Voltage and frequency values Compare the voltage and frequency values with the data for the mains power supply Connect the compressor motor in accordance with the circuit diagram (see inside of terminal box). Compare the voltage and frequency values with the data for the mains power supply. Only connect the motor if these values are the same compressors marked in this way are suitable for direct or part winding start.  The motor winding is divided into two parts: part winding 1 = 50 % and part winding 2 = 50 %. This winding division reduces the start-up current during a part winding start to approx. 50 % of the value for a direct start. Reversed fields of rotation In the factory, as shown below in Figure 4, the motor is switched for direct starting (YY). For part winding start (Y/YY), remove the bridges and connect the motor feed cable according to the circuit diagram. The motor is switched for direct starting (YY). Failure to comply results in reversed fields of rotation and can cause motor damage. After the motor has started up with part winding 1, part winding 2 must be switched on after a maximum 1-second delay. Failure to do so can be detrimental to the service life of the motor. Ensure that power is supplied via QA2 to winding 1 (50%) (1U1/1V1/1W1) and via QA3 to winding 2 (50 %) (2U1/2V1/2W1). The motor contactors (QA2/QA3) are each to be rated for approx. 50% of the maximum operating current. Danfoss BOCK compressors Transcritical CO2 compressors, like the Danfoss BOCK product line, offer a wide span of capacities with up to 162 kW of cooling capacity (14°F/95°F/18R/60 Hz) and 420 kW of heating capacity (41°C/77°C (100 bar)/18R/60 Hz) for many different product applications, including food retail, heat pumps, district heating, industrial refrigeration and process heating, reversible chiller/heat pumps for HVAC, cold storage, chillers, and data centers. Low and medium temperature levels are available, with high stand still pressures. This high capacity reduces the need for multiple compressors, simplifying system design and reducing investment costs. The Danfoss BOCK compressors also feature a high-pressure rating of 130 bar in operation/150 bar at stand still on the high side and 65 bar in operation/100 bar at stand still on the low side.

Although energy efficiency continues to be a focus of home renovation, HVAC professionals are sometimes hesitant to work on older homes. The potential costs and complexities of replacing outdated HVAC systems or installing a solution where one doesn’t exist can make them nervous. However, installing all-electric, all-climate heat pumps in homes built decades ago, even a century ago, is an everyday occurrence in the northeastern U.S. Heating and cooling systems A sizable portion of Jay Moody Heating & Air Conditioning consists of installing and servicing energy-efficient heating and cooling systems, especially heat pumps, in older homes in central Massachusetts. Updating older homes with heat pump solutions is more feasible than many think — it’s a matter of overcoming common barriers and being the right, experienced HVAC professional for the job. Common barriers when heating and cooling an older home In Massachusetts, it’s common to have one or more 275-gallon tanks of oil in the basement to heat homes Barriers to renovating older homes are surmountable. Commonly, older homes lack adequate filtration and insulation and are equipped with older electrical panels that might need upgrading or replacing.  In Massachusetts, it’s common to have one or more 275-gallon tanks of oil in the basement to heat homes. However, whether an older home is heated with oil or gas, outside air infiltration occurs because these structures generally lack a tight building envelope. More recently built homes have these systems to prevent outside air and water from penetrating the structure. Similarly, many older homes are insufficiently insulated. Size of the structure and other electrical loads As a first step, owners of older homes should get an energy audit and find out what can be done to eliminate infiltration, such as having air sealing performed and having more insulation blown into their houses. Once weatherization is complete, installing an all-electric heat pump system becomes more feasible. Another important requirement would be an appropriately sized electrical panel. Older homes might have 100 amps of service, for example, when it will need 200 amps for the new heat pump, depending on the size of the structure and other electrical loads such as electric stoves/ovens, water heaters, and electric vehicles. In some cases, an electrical panel upgrade may be required. Attributes homeowners look for in an HVAC company HVAC companies that specialize in heat pumps should ensure their HVAC technicians are shared and ongoing training When upgrading an older home with a heat pump system, it’s a best practice for homeowners to get multiple quotes from experienced contractors in their service area. To stand out and offer more value during this process, my business conducts monthly heat pump workshops that help educate customers. Additionally, I recommend that any experienced, reputable HVAC company should post online reviews, have a professional website and online presence, and show relevant work examples to help familiarize homeowners with their work. HVAC companies that specialize in heat pumps should ensure their HVAC technicians are experienced and undergo ongoing training. In fact, the Jay Moody team is part of the Mitsubishi Electric Diamond Contractor® program, which provides in-depth training on heat pump solutions. Homeowner’s comfort preferences During the in-home consultation, the salesperson should discuss the homeowner’s comfort preferences, HVAC concerns, and short- and long-term plans for the home and its HVAC system. The contractor should conduct an in-house Manual J to calculate the heating and cooling loads of the home, ensuring proper HVAC equipment sizing for efficient and comfortable performance. Lastly, the HVAC salesperson should make suggestions for keeping the aesthetics of an older home intact. For instance, my team would not use mini-splits in certain rooms in a Victorian home because they might detract from the style. Instead, they would likely suggest a ducted heat pump system with air handlers and stylish vents. HVAC salesperson should make suggestions for keeping the aesthetics of an older home intact. Heat pumps offer the right fit for homes of all ages In the Northeast, many of the homes are older – whether that means built in the 1960s, the 1860s, or the 1760s. There’s little reason that any HVAC contractor should shy away from installing heat pump systems in older homes. Further, contractors can learn how to teach homeowners about heat pumps, train their teams, and recommend the right system for the character of the house. Refurbishing these beautiful houses is a challenge well worth tackling to create homes as energy-efficient and comfortable as they are charming.

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

The U.S. Department of Energy (DoE) Commercial Heat Pump Accelerator program is designed to enhance building efficiency and electrification. Running from 2024 through 2027, the program aims to overcome adoption barriers, promote advanced heat pump technologies, and create sustainable solutions for HVAC professionals. Compared with conventional packaged rooftop units (RTUs) with natural gas heating, heat pump RTUs are estimated to reduce greenhouse gas emissions and energy costs by up to 50%. For those in the HVAC industry, this program is an opportunity to boost operational efficiency, align with emerging sustainability standards, and unlock new business. Transforming Commercial HVAC with Heat Pumps Known for their dual heating and cooling abilities, heat pumps save energy compared to conventional HVAC systems The DoE’s program centers on accelerating the adoption of high-efficiency heat pumps for space conditioning and water heating.

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

With a reputation for uncompromising integrity, HDG Legacy is an experienced voice in the hospitality industry for those looking to build, own, and operate hotels. As both a respected developer and preferred management company, the Legacy team employs its core values of teamwork, communication, innovation, leadership and resourcefulness, and has an established reputation for positively impacting the hospitality sector. Currently, Legacy manages and maintains nine hotels that it owns, with its tenth opening July 2025. Rising energy and water costs  A commitment to improving and innovating hotels means that Legacy is alive to the economic challenges facing hoteliers, not least in operational challenges because of rising energy and water costs. With profit margins often razor-thin, even small innovations can mean the difference between profit and loss, so it was no surprise that Legacy looked to Anacove’s unique AI- and Cloud-powered Smart Thermostats, Leak Detection and Asset Management systems to help give its hotel clients the edge in their energy and water management. Anacove’s Smart Thermostats  “One of my core beliefs is that operating a business that respects the environment in terms of how resources are utilized is important just because that's the right thing to do – but there's also an economic benefit,” explained Navroz F. Saju, Founder and Principal at HDG Legacy. “We initially tested Anacove’s Smart Thermostats across our express properties, before piloting them in one of our larger hotels, and we were so impressed with the results (we actually have the data showing the savings for 2024-25 thus far – very impressive!) that we are looking to roll out the solutions across our other properties.” Electricity consumption reduced He continued, “We started using Anacove Smart Thermostats in July 2024 at the Holiday Inn Express Crystal River, and based on historical data and usage, electricity costs on our utility bills are 35.94% lower per occupied room.” “The Holiday Inn Express & Suites Silver Springs-Ocala’s electricity costs were 33% less than what we’d budgeted for per room, with the Holiday Inn Express & Suites Inverness-Lecanto coming in at 43% lower than budgeted in electricity usage.” Features of Smart Thermostats  Anacove’s Smart Thermostats are innovative IoT devices with advanced sensors Anacove’s Smart Thermostats are innovative IoT devices with advanced sensors that monitor temperature, humidity, air quality, barometric pressure, current weather conditions, daylight conditions and guest presence. They seamlessly integrate with HVAC systems through existing hotel WiFi infrastructure, allowing for centralized control throughout the hotel. This enables continuous optimization of each room, regardless of occupancy status, leading to immediate and sustained cost savings. Unlike other occupancy-sensing thermostats, Anacove Smart Thermostats remain active even when guests are asleep or have left their pet in the room. Optimizing HVAC Cycles  Learning from each room’s thermal behavior – heating and cooling coefficients – the thermostats optimize HVAC cycles, resulting in reduced peak energy consumption, and maintenance of guest comfort with less energy usage. “I have been very pleased with the transition to Anacove Smart Thermostats, and we will continue to replace older, less efficient thermostat technology with Anacove thermostats,” added Saju. “They are easier to operate – for staff and guests – and install than others on the market – irrespective of their superior energy-saving performance – and are incredibly responsive.” Anacove’s staff and support Such was their ease of use that Legacy’s skilled maintenance staff installed the Anacove Smart Thermostats themselves, but Saju is keen to point out how engaging Anacove was throughout the process. “Their support has been excellent. Even though the thermostats are easy to install and operate, if there is ever a question that needs answering the Anacove team is there to back us up very quickly and in a very expert way,” he said. “I've been very comfortable with their price point – I actually think that their thermostat pricing is the most competitive I have found – and with their after sales service and the technology’s ease of use they are very customer-centric indeed.” Anacove’s AI-enabled water management systems  In addition to rolling out Anacove’s Smart Thermostats incrementally across his hotels, Saju is also deploying the company’s AI-powered, cloud-maintained Toilet Leak Detectors and Asset Tracking Systems. The AI-enabled water management systems go beyond basic leak detection. While sensors installed in water tanks or behind walls detect even the tiniest leaks, it’s the AI that identifies anomalies, pinpoints problem areas, and alerts maintenance teams before the issue escalates – saving water, money, repair costs, and mitigating guest inconvenience. Anacove’s Asset Management System  Anacove’s Asset Management System equips hotel assets such as luggage carts, rollaway beds, cribs, housekeeping trollies and other movable items with location tags, which, thanks to the cloud-maintained AI system, helps to track down missing items, triangulating their exact positions, streamlining retrieval, reducing loss, and improving overall resource management. “We all expect a lot from our hotel’s front desk,” said Saju. “They’ve got to check people in, the phone's ringing, someone wants a bandage and then suddenly someone will check in and say, ‘where's the luggage cart?’” “The fact that they're immediately able to log in to the Anacove cloud dashboard on their phone and see exactly where the cart is – usually in a guest’s room – is an incredible time-saving benefit, enabling them to locate the cart’s exact location so that they can repurpose the cart for another guest’s use. In the past they would have to ring around guests’ rooms to find it – a waste of time and valuable resources.” Anacove AI cloud brain The performance of all four Anacove technology services (thermostats, toilet leaks, staff and asset trackers) are monitored and analyzed by the company’s AI cloud system, effectively a brain hovering over key operational areas of the hotel that make intelligent decisions. This ‘Anacove AI cloud brain’ – the only system of its kind – looks at the whole hotel as a single living entity, autogenerating reports that allow hoteliers to clearly see the return on their investment. The AI-enabled, cloud-connected energy management solution uses one inclusive dashboard, with a data-rich, monthly ‘flash report’ that provides a summary of how much energy has been saved, what's going on in terms of potential toilet leakage, etc. Easy and energy efficient  Overall, Saju is delighted with not only Anacove’s innovative, unique, AI-powered, cloud-connected devices, which are exceeding Anacove’s own expectations, but also by the company’s service and support. “They advertised a saving of about $12.00 per-room per month for the Smart Thermostats, which was pretty significant, but we're beating those numbers,” he explained. “Overall, all their technology is easy to install and use. There are huge savings, and – importantly – our general managers are very happy!” “Anacove’s after-sales service has also been second to none, and they have been incredibly receptive in helping us adapt the systems to our own requirements. I am a huge fan of Anacove and the team there; they're good people and I'm so glad that we're able to work together.”

Users can calculate their carbon emissions using Wren’s intuitive calculator and fund various climate projects, including refrigerant destruction. Wren emphasizes transparency by providing regular updates on the impact of contributions, including data, photos, and stories. The platform aims to make climate action simple and effective, ensuring that every dollar contributes to meaningful environmental change.  About A-Gas  A‑Gas is a world pioneer in the supply and lifecycle management of refrigerants and associated products and services. Through the first-class recovery, reclamation, and repurposing processes, we capture refrigerants and fire protection gases for future re-use or safe destruction, preventing harmful release into the atmosphere. For over 30 years, A-Gas has supported clients and partners on their environmental journey by supplying lower global warming gases and actively increasing the circularity of the industries we serve, building a sustainable future.   Challenge  HCFC-22 is a potent greenhouse gas with a global warming potential (GWP) much higher than CO2 The widespread use of refrigerants like HCFC-22 (R22) presents a significant environmental challenge. HCFC-22 is a potent greenhouse gas with a global warming potential (GWP) much higher than CO2 (one molecule of R22 has a global warming impact 1,810 times that of one molecule of CO2). If not properly managed, its release would have a negative impact on the atmosphere. As these refrigerants reach the end of their lifecycle, there is an urgent need for effective solutions to prevent their emissions and minimize their environmental impact.   Solution  To address this challenge, A-Gas recovers refrigerants for reclamation or destruction at A-Gas facilities across the country. By leveraging Wren's platform to mobilize individual contributions and A-Gas' technical expertise in lifecycle refrigerant management, this partnership enabled an environmentally conscious solution for the used refrigerant. It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry through its on-site refrigerant recovery service (Rapid Recovery®), refrigerant buyback programs, and wholesale supplier reclaim program (Refri-Claim™). HCFC-22 destruction project The ACR methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017 Wren and A-Gas formed a partnership to provide Wren subscribers with the opportunity to fund an HCFC-22 destruction project through the generation of A-Gas carbon credits to ensure the gas does not escape into the atmosphere. While the ACR (formerly American Carbon Registry) methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017, few have completed such projects because the price of HCFC-22 is so high; it is more profitable for organizations to reclaim this product.  ACR’s methodology As such, this is one of the first HCFC-22 destruction projects utilizing ACR’s methodology. Approved by the International Civil Aviation Organization (ICAO) to provide carbon credits in its Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), ACR is highly regarded across the world.  Results  The partnership yielded multiple environmental benefits:   Emissions Avoided: The initiative successfully avoided the release of 16,000 tons of CO2-equivalent emissions by destroying HCFC-22. This substantial elimination of greenhouse gas emissions demonstrates the effectiveness of the program.   Subscriber Engagement: Wren provided its subscribers with detailed updates on the impact of their contributions. These updates included data on the quantities of HCFC-22 destroyed and the corresponding emissions reductions. This transparency helped build trust and encouraged ongoing participation in climate action.   Educational Impact: The collaboration raised awareness about the importance of proper lifecycle refrigerant management. Wren and A-Gas educated the public on lesser-known aspects of climate change mitigation by highlighting the environmental benefits of destroying high-GWP substances.   Conclusion  This partnership enabled an environmentally conscious solution for the used refrigerant By leveraging Wren's platform to mobilize individual contributions and A-Gas' technical expertise in lifecycle refrigerant management, this partnership enabled an environmentally conscious solution for the used refrigerant. It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry.  refrigerant destruction protocols and technology "We are excited to work with A-Gas to push forward the standard of refrigerant destruction protocols and technology," said Landon Brand, CEO, of Wren. Landon Brand adds, "This is one of the most reliable and impactful project types we have found in our years of funding climate solutions, and we hope our community can keep blazing a trail to eliminate these dangerous refrigerants."

The Olsen Group, based in Boca Raton, Florida, is a national pioneer in HVAC energy optimization. Donald Olsen and his seasoned team of HVAC control specialists have been in business for two decades, integrating energy-saving solutions into over a thousand commercial and large-scale residential projects. In the process, the Olsen Group has become one of North America’s top suppliers of Verdant thermostats. Verdant devices leverage intelligent occupancy sensors and proprietary software to reduce HVAC runtimes by 45 percent on average. HVAC control integration Verdant’s effectiveness, reliability, and broad compatibility have made Verdant the energy management solution of choice for thousands of hotels and MDUs, including multifamily buildings, senior living, and student housing.  The Olsen Group has forged a productive two-way partnership with Verdant. Donald Olsen and his team have made it a priority to share data, customer feedback, and requirements with Verdant – and Verdant, in turn, has come to rely on Olsen when they need to field test a new solution. In May of 2024, Verdant reached out to Olsen for help with a new pilot program aiming to facilitate more effective HVAC control integration, easier service, and deep energy savings for MDU projects around the globe. The Challenge Commercial VRF systems have an extremely attractive set of upsides for hotel operators Inverter (VRF) system design is becoming increasingly common in hospitality settings. Commercial VRF systems have an extremely attractive set of upsides for hotel operators. They are significantly more energy efficient and quieter than traditional VTACs or PTACs; they can provide simultaneous heating and cooling to different zones for optimal guest comfort; and they allow both individual room-level setpoint control and building-level centralized management. However, the majority of VRF units cannot connect directly to a third-party smart thermostat. Because they rely on proprietary manufacturer protocols for variable speed commands and internal diagnostics, VRF units require an external control solution to facilitate bidirectional communication with Verdant thermostats. Installation and commissioning process Every additional component in a system adds complexity and opportunity for human error. In hotels, that complexity is multiplied across hundreds of rooms. “HVAC systems are installed dark for new builds, with no power running to the site,” says Donald Olsen, President and Owner of the Olsen Group. “There’s no way to test as we go. If there are any mistakes during installation, we find out about it when the lights go on after project completion.” And mistakes are nearly inevitable. Some third-party controllers have prominent dipswitches that can be easily snagged or tripped during transportation or installation, altering their configuration and causing them to fail once the system is powered. These switches are often accidentally tripped multiple times throughout the installation and commissioning process, pioneering to a never-ending cycle of errors and service calls. VRF control solutions  Adding to the issue, not all third-party control keys have the ability to retrieve and solve system error codes “Once properly configured and installed, VRF control solutions tend to be incredibly reliable,” says Olsen. “Getting them there is a real challenge, however. Accidents, human error, and repeated recalibrations can drive serious project overruns and client dissatisfaction.” Adding to the problem, not all third-party control solutions have the capability to retrieve and translate system error codes. “If the central management system isn’t getting certified manufacturer control signals from the control device, it may no longer recognize the thermostat. The system will continue to function, but it will always show up in the central manager with an error message,” warns Olsen. Airzone Aidoo Pro control solution These false error reports degrade the overall utility of the central management system, robbing operators of the ability to detect and mitigate problems proactively and requiring onsite testing to diagnose any issues. As VRF systems become the norm for hospitality projects, Verdant needed a solution to reduce the possibility of accidental misconfiguration and improve visibility into system functionality. They called on Olsen to conduct a pilot program, retrofitting sixteen VRF units in the Jacksonville Beach, FL Springhill Suites with the Airzone Aidoo Pro control solution. The Solution For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller The Jacksonville Beach Springhill Suites is a 156-room hotel with a state-of-the-art Daikin VRV rooftop chiller system. The Airzone Aidoo Pro ships preconfigured for the specific HVAC unit model, reducing the possibility for errors during initial installation. For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller. This 1:1 system design simplifies operations and troubleshooting: Any issue can be immediately traced back to a single unit, minimizing the scope and duration or repair downtime. “The Airzone Aidoo Pro offered two key upgrades as a VRV control solution,” says Olsen. “First, the dipswitches are recessed, making them much harder to trip accidentally. Second, Aidoo makes the system much easier to service. We can read error codes, run tests, and diagnose issues remotely, without ever needing to disrupt a guest’s stay.” Airzone’s expansive library This advanced remote management is enabled by Airzone’s expansive library of manufacturer protocols. “Because of our close relationship with HVAC manufacturers, Aidoo Pro can provide the proprietary control signals the central management system is expecting to see,” says Borja Fernandez, Director of OEM Solutions, Airzone. “That preserves all the features of the HVAC unit and thermostat, while also eliminating persistent false error codes. With Aidoo Pro, the central management system can function as a single-pane-of-glass HVAC monitoring and control solution for the building, as intended.” Results and Next Steps The pilot program is expanding to new builds around the globe, including projects in the UK Olsen reports that Springhill Suites is happy with their upgraded VRV system. “They have more visibility into the system and fewer services calls,” says Olsen. “When there is an issue, we can diagnose it remotely for faster resolution and less guest room downtime. It’s a much better customer experience overall.” Verdant is encouraged as well. This pilot program is expanding to several new builds around the globe, including projects in Central America, the Caribbean, the UK, and the EU. HVAC energy savings “There is a massive untapped market for energy-efficient HVAC upgrades in the Caribbean region,” says Olsen. “Energy costs there can exceed a dollar per kilowatt hour. Cost-effective devices like Verdant thermostats and the Airzone Aidoo Pro pay for themselves very easily in that scenario.” Verdant and the Olsen Group have built global brands by helping commercial properties realize significant HVAC energy savings.
