For warehouse and factory owners, cutting their heat energy bills by over 90% might seem like a pipedream. I’ve been in enough warehouses to know one thing: heating them is expensive and frustrating. It often feels like throwing money into the wind. However, times are changing, and with the introduction of Shortwave Infrared (SWI), a revolutionary technology set to redefine warehouse heating, business owners can finally achieve energy savings on the scale they need. Shortwave Infrared (SWI) For warehouse owners, slashing heat energy bills by more than 90% might sound far-fetched. Having spent time in countless warehouses, I know one thing: heating them is both costly and frustrating like throwing money into thin air. But times are changing. With the arrival of Shortwave Infrared (SWI), a ground-breaking technology poised to transform warehouse heating, business owners can now achieve the substantial energy savings they've been seeking. Beyond the Status Quo Faced with soaring bills, warehouse, and factory owners are actively seeking better alternatives For years, warehouse heating has been stuck in a cycle of inefficiency opting for bulky systems that consume vast amounts of energy but offer little in return. High heating bills were once seen as an unavoidable cost of doing business. However, the energy price hikes of 2021 and 2022 completely changed the game, straining heating budgets and forcing a rethink of what's acceptable. But there are positives to find in the situation. Faced with soaring bills, warehouse, and factory owners are actively seeking better alternatives. Next-gen technology An industry long overdue for disruption has finally found the push it needed to embrace 'next-gen' technology. Enter Shortwave Infrared, ready to take the spotlight. At the forefront of the heating revolution, it’s delivering unprecedented energy savings and cost efficiency, setting a new standard for businesses nationwide. Lost in Translation So, what sets SWI apart, and why does it outperform current systems? It all comes down to SWI's core heating principles. One of the most rewarding moments of my career was seeing the reaction of workers, shivering in a drafty space, suddenly feeling the warmth from SWI heaters. Their faces said it all – they couldn’t believe how something so simple could work so effectively. However, the main issue is that currently, the warehouse and logistics sector largely depends on convection heating, which works by warming the air within a space. While this might be adequate for smaller, enclosed areas, it falls short in large, open-plan spaces where heat quickly dissipates. Basic physics Turning up the thermostat won’t help either, as the principles are floored from the beginning It all comes down to basic physics, warm air rises. In buildings with high ceilings, this means heat drifts upwards, leaving workers on the ground cold, while the warmth stays out of reach. The issue is made worse by large doors and windows, which allow even more heat to escape. For those lucky enough to be near a heater, it can be hit-or-miss. Turning up the thermostat won’t help either, as the principles are floored from the beginning. You’ll just be draining budgets quicker than before. SWI: A New Frontier On the other hand, Shortwave Infrared Heating offers a revolutionary solution. By providing localized heat, it ensures workers stay comfortable and productive, regardless of the ambient temperature. Unlike traditional heating systems, SWI eliminates heat loss by targeting individuals directly – a feeling akin to the warm sun on your back. This strategic approach not only saves energy, but also creates a more comfortable workspace, making it an ideal solution for businesses seeking major efficiency and cost savings. Cost and carbon savings Unlike convection heating, SWI also delivers consistent warmth, eliminating cold spots. Additionally, its electric power source offers substantial cost and carbon savings, making it a sensible choice for those looking to align their heating systems with ESG initiatives. The Verdict is In By implementing SWIR, we helped them achieve a 90% reduction in energy consumption The good news is that the word is out, and companies are now reporting over 90% energy savings while drastically reducing their carbon footprints. A recent customer faced the challenge of heating a massive 5,000-square-meter space. By implementing SWIR, we helped them achieve a 90% reduction in energy consumption, exceeding expectations. Annual energy consumption The numbers speak for themselves. Annual energy consumption dropped from 150,000 kWh (gas) to 16,000 kWh (electricity), showcasing the incredible potential for change in UK businesses. This is just one example, imagine what we can achieve rolling out SWI across the country, The positive impact on the bottom line has prompted the company to implement SWI across all of its UK sites. As a sustainability-driven business, SWI provides a crucial solution to reduce reliance on carbon-heavy fossil fuels. The Future is Bright SWI's potential to transform warehouse and logistics is endless and businesses are now waking up to its potential, and are rightly being drawn in by the idea of significant cost and carbon savings. It’s a shift in mindset that’s challenging traditional heating methods. By focusing on precise, targeted warmth, rather than wasteful, resource-heavy convection heating, UK businesses are already saving millions of pounds each year. Efficiency of infrared technological challenges Business owners are accustomed to thinking of heating as raising the overall temperature of a space Yet one of the biggest challenges the industry faces is a mental one, not a mechanical one. Business owners are accustomed to thinking of heating as raising the overall temperature of a space. However, this outdated approach fails to consider the efficiency of infrared technology, which delivers focused warmth directly to workers, equipment, or specific areas. Impact of SWI I'm always thrilled to see the reactions of customers amazed by the impact of SWI. However, we need more people to embrace this innovative heating method, which means winning more hearts and minds. For those ready to make the switch, the benefits will be substantial, potentially saving thousands, if not millions, on heating bills at a time when they need it most.
Data centers worldwide are under intense pressure. High-powered computing is a global necessity that seemingly gets more demanding by the day. There’s also the need to prioritize sustainability improvements ranging from resource conservation to decarbonization. And data centers must consider their bottom line and remain competitive. Anticipating the challenges data centers will continue to face, scientists and engineers have innovated two-phase (2-PIC) immersion cooling. With the capacity to meet the elevated cooling requirements driven by high-powered computing, this next-generation solution delivers on environmental priorities by significantly lowering data center energy consumption, slashing, if not eliminating, water use, while supporting decarbonization, circularity missions, and more. Emergence of 2-PIC Traditional approaches are fast approaching capacity for meeting current and future cooling needs The emergence of 2-PIC comes at a critical time, because the traditional cooling methods that have kept data centers up and running so far—namely air cooling and water cooling—are doing so at the detriment of the planet. Additionally, these traditional approaches are quickly approaching capacity for meeting current and future cooling needs. Air- and water-cooling methods are used in approximately 95% of the estimated 8,000 data centers that exist today. The criticality of high-powered computing Once seen as a future need, high-powered computing, and faster-than-ever processing are now established as critical to the operation of businesses, governments, organizations, and other entities that support the way communities function, survive, and thrive. Whether it’s health and wellness, financial institutions, economic growth, safety and protection, entertainment, education, or any other service supporting our way of life, successfully providing that service fully depends on the ability of data centers to quickly and reliably obtain, store, and process data. Influence of AI AI has a profound influence and, generates far more power than traditional internet uses Moreover, when we say “data centers,” we’re not just speaking of big players like Microsoft, Google, Meta, and Amazon. Equally dependent on high-performance, high-speed computing are enterprise data center operators, such as our governments and military, financial institutions, healthcare systems, educational institutions, and more. We also must acknowledge the profound influence of artificial intelligence (AI), which generates far more power than traditional internet uses. Its effects are far-reaching, enhancing patient care, supporting risk management and fraud detection in finance, boosting crop yields within agriculture, and more. The environmental costs of data centers According to the latest estimates by the International Energy Agency, data centers worldwide produce 1% of energy-related carbon emissions and in 2022 used approximately 460 TWh of electricity per year—equating to 2% of global electricity demand. McKinsey and Company estimates 40% of this electricity is used for data center cooling. Data centers’ impact on the environment also includes their significant water consumption, averaging 300,000 gallons per day, and a physical footprint that averages 100,000 square feet but in the case of some hyperscale data centers can range between 1.3 to 2 million square feet. In terms of growth, a U.S. market report from Newmark tells us that in the U.S. alone, the U.S. data center footprint will absorb 35 gigawatts by 2030, which is more than twice the data center power consumption of 2022. The emergence of liquid cooling: the elevated interest in 2-PIC From reducing energy and water consumption to shrinking physical footprints, 2-PIC offers the planet a better data center solution. In less than two years, traditional cooling systems won’t be able to support the exponential growth in the world’s data processing and storage applications. Based on publicly available product roadmaps from major chip manufacturers, by 2026, air-cooled systems will no longer be able to meet the cooling needs of most next-generation, high-performance computing chips. Capable of removing heat more effectively than air cooling, liquid cooling uses a liquid such as water or a dielectric fluid to cool the heat-generating components of servers. The liquid can cool these components directly, or it can be done indirectly through a heat exchanger. With two-phase immersion cooling the entire server rack is submerged in a tank filled with a dielectric fluid. Single-phase and two-phase liquid cooling Single-phase liquid cooling uses a pump to circulate the liquid through a closed-loop system Single-phase liquid cooling uses a pump to circulate the liquid through a closed-loop system. Two-phase liquid cooling uses a phase-change material, such as a refrigerant, which evaporates and condenses as it absorbs and releases heat. With 2-PIC, which is a form of two-phase liquid cooling, the entire server rack is submerged in a tank filled with dielectric fluid. The fluid boils as it’s heated by the components of the servers, creating bubbles that rise to the surface and condense in a heat exchanger. Gravity then returns the condensed fluid to the tank, creating a natural circulation loop that does not require pumps or fans. Advantages of 2-PIC 2-PIC is commanding attention as the solution for meeting the cooling demands of the high-powered computing components of today and tomorrow. Moreover, the technology of 2-PIC systems, combined with the right dielectric fluid, delivers advantages to “take the heat off” data centers. Here’s a breakdown of additional 2-PIC benefits: Up to 90% reduction in energy consumption: Based on modeling completed by the industry, 2-PIC is expected to reduce up to 90% of data center cooling energy consumption and 40% of overall data center energy consumption*. (*Compared to traditional air-cooling technologies) Enhanced computing performance and data center reliability: 2-PIC allows servers to operate at higher temperatures and power densities, while reducing the risk of overheating. Significant reduction in water consumption: Depending on the data center location and cooling design methodology, water consumption could even be eliminated completely. 60% reduction in the physical footprint: 2-PIC reduces the space required for cooling equipment, freeing up more floor area for servers and increasing the rack density of the data center. Lower GWP and circularity: Chemours Opteon™ 2P50 is a developmental dielectric heat-transfer fluid, currently pre-commercial, pending regulatory approval. It offers an extremely low global warming potential (GWP) of 10 and was specifically created to optimize the performance of the electronic components in a 2-PIC system. This 2-PIC fluid also enables the reprocessing/reuse of existing fluid to maximize circularity. The bottom line: In addition to other compelling data, a recent study commissioned by Chemours and LiquidStack through Syska Hennessy, revealed that, compared with other state-of-the-art liquid cooling methods, 2-PIC can deliver up to a 40% lower total cost of ownership (TCO) and significantly reduce operational expenditures (OPEX), with savings ranging from 54% to 88.6%. Benefits of new data center cooling technologies compared to single-phase direct-to-chip, and single-phase immersion methods. 2-PIC, the future-ready solution As the world’s reliance on AI and other high-powered computing capabilities escalates, data center cooling solutions must grow with demand while significantly reducing their impact on the environment. In global energy savings alone, 2-PIC could generate an estimated savings of 340 TWh by 2055—the equivalent of powering more than 517 million laptops 24/7. And even with increasing IT loads, 2-PIC maintains its performance, ensuring long-term cost-effectiveness and adaptability to meet future demands. With society at a crossroads between the criticality of high-powered computing and a planet in crisis, the industry is turning its attention to 2-PIC as the solution for today and tomorrow.

Case studies
OTS R&D, Inc., in collaboration with the Copper Development Association (CDA), provides design support to optimize copper tube aluminum fin heat exchangers for commercial dehumidification. Problem In collaboration with the Copper Development Association (CDA) and OTS R&D, Inc. (OTS), AprilAire, a manufacturer of dehumidification equipment, they sought to maximize the performance of their products in both standard and low-temperature operating conditions while avoiding frost accumulation on the evaporator. Traditional dehumidifiers often lose efficiency as frost accumulates, leading to disruptions in conditioning and temporary spikes in humidity. Copper tube fin heat exchangers OTS supports innovation and next-generation product development using industry-pioneering software The question was whether small-diameter copper tube fin heat exchangers could maintain or increase efficiency while preventing frost accumulation in these unique operating conditions. OTS is a CDA partner that provides crucial heat transfer and system integration expertise to the industry, specifically in air conditioning, heat pumping, refrigeration, and energy conversion. Having roots with faculty and research at the University of Maryland, OTS supports innovation and next-generation product development using industry-pioneering software. Solution Through extensive research and simulation using the CoilDesigner® tool, the OTS project team explored various heat exchanger designs and airflow rates to identify optimal configurations. The study focused on reducing the outside diameter of the copper tubes from conventional values to 5mm and selecting copper as the tube material. The optimization study considered seven different tube fin geometries, ranging from 5mm OD options to 7.94mm OD tubes. Various parameters Using small-diameter copper tubes (5mm) provides several benefits for heat exchangers and overall advantages Various parameters such as fin density, coil height, number of tubes, circuitry, and airflow rates were analyzed to maximize dehumidification rate, efficiency, and frost avoidance while minimizing material consumption and refrigerant charge. Using small-diameter copper tubes (5mm) provides several benefits for heat exchangers and overall advantages for original equipment manufacturers (OEMs). Energy efficiency Reducing the diameter of copper tubes within coils offers a cost-effective avenue for enhancing system energy efficiency. While alternative methods might bolster system energy efficiency by increasing the number of conventional tubes, this approach incurs penalties such as augmented weight in tube and fin materials and heightened refrigerant volume. Conversely, reducing tube diameter fosters more efficient heat transfer and yields smaller, lighter coils. This reduction in materials can maintain or even enhance heat transfer efficiency while enabling smaller overall product dimensions, facilitating easier storage, transport, and installation, and ultimately reducing the footprint at the point of use. Significant advantage Coils constructed with CTAF or CTCF stand as enduring and reliable solutions within the industry Moreover, small-diameter copper tubes present a significant advantage in reducing refrigerant volume within systems. The diminished internal volume of the coils necessitates less refrigerant to charge, pioneering further benefits in system design, including a notable decrease in overall system weight. Coils constructed with copper tubes and aluminum fins (CTAF) or copper tubes and copper fins (CTCF) stand as enduring and reliable solutions within the industry, setting the standard for corrosion resistance and long-term service life. With a high level of familiarity across the supply chain, from tube suppliers to HVAC/R contractors, the transition to these innovative copper tubes ensures continuity in fabrication, assembly, installation, service, repair, and recyclability processes, maintaining efficiency and reliability throughout. Results After the project, the team identified 13 candidate designs meeting the product requirements, with seven using 5mm OD tubes and six using 7.94mm tubes.

With 53 men on the Jacksonville Jaguars roster, practicing 5 to 6 days per week for 10 to 12 hours a day, the demand for hot water must be enormous. As the choice for the team’s practice facility’s hot water storage and water heating capabilities, we happen to have the deets. How about 1,880 gallons of storage capacity and 2,400,000 btu/hr heating the water? Miller Electric Center The Miller Electric Center is a new state-of-the-art practice facility in downtown Jacksonville that serves as the Jaguars’ football operations headquarters. The 120 million dollar facility is 125,000 square feet and includes locker rooms, training and medical facilities, office space, and a draft room. It also features two full-size grass practice fields and one indoor field, along with shaded public viewing stands, concession areas, and a team store. Big men need big spaces Armor’s SMART TOUCH operating control makes adjusting parameters and troubleshooting a breeze Luckily, Lochinvar’s Armor Condensing water heaters are up for the job. The Armor’s stainless steel heat exchanger delivers hot water at 98% thermal efficiency and modulates at a 10:1 turndown ratio. That means the units can fire as low as 10% of their total capability and modulate up to 100% when the demand is greatest. The Jag’s facility has 3 of the AWH0800NPM units installed providing the ability to cascade which ensures the units operate with equal runtime and extends the life of the heaters. The Armor’s SMART TOUCH operating control makes adjusting parameters and troubleshooting a breeze – which is nice in Florida. Lock-Temp Round Jacketed Storage Tank With a proven storage vessel like the Lock-Temp Round Jacketed Storage Tank, making sure the stored hot water is ready for delivery is a given. These tanks have the exclusive Lock-Temp baffle that keeps water evenly stratified and the 80% draw factor allows almost the entire capacity to be used at the designated temperature. installation and commission With the help of a local manufacturers’ rep firm, Harry Warren, the installing contractor, Touchton Plumbing out of Jacksonville reported that the whole experience went off without a hitch. “The installation went extremely well, and the units have been working without fail through the first year of the facility being in use,” said Parker Touchton, project manager. The equipment was installed and commissioned according to schedule and is said to be performing as promised and at the end of a 12-hour practice, there’s no room for disappointment.
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.

Users can calculate their carbon emissions using Wren’s intuitive calculator and fund various climate projects, including refrigerant destruction. Wren emphasizes transparency by providing regular updates on the impact of contributions, including data, photos, and stories. The platform aims to make climate action simple and effective, ensuring that every dollar contributes to meaningful environmental change. About A-Gas A‑Gas is a world pioneer in the supply and lifecycle management of refrigerants and associated products and services. Through the first-class recovery, reclamation, and repurposing processes, we capture refrigerants and fire protection gases for future re-use or safe destruction, preventing harmful release into the atmosphere. For over 30 years, A-Gas has supported clients and partners on their environmental journey by supplying lower global warming gases and actively increasing the circularity of the industries we serve, building a sustainable future. Challenge HCFC-22 is a potent greenhouse gas with a global warming potential (GWP) much higher than CO2 The widespread use of refrigerants like HCFC-22 (R22) presents a significant environmental challenge. HCFC-22 is a potent greenhouse gas with a global warming potential (GWP) much higher than CO2 (one molecule of R22 has a global warming impact 1,810 times that of one molecule of CO2). If not properly managed, its release would have a negative impact on the atmosphere. As these refrigerants reach the end of their lifecycle, there is an urgent need for effective solutions to prevent their emissions and minimize their environmental impact. Solution To address this challenge, A-Gas recovers refrigerants for reclamation or destruction at A-Gas facilities across the country. By leveraging Wren's platform to mobilize individual contributions and A-Gas' technical expertise in lifecycle refrigerant management, this partnership enabled an environmentally conscious solution for the used refrigerant. It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry through its on-site refrigerant recovery service (Rapid Recovery®), refrigerant buyback programs, and wholesale supplier reclaim program (Refri-Claim™). HCFC-22 destruction project The ACR methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017 Wren and A-Gas formed a partnership to provide Wren subscribers with the opportunity to fund an HCFC-22 destruction project through the generation of A-Gas carbon credits to ensure the gas does not escape into the atmosphere. While the ACR (formerly American Carbon Registry) methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017, few have completed such projects because the price of HCFC-22 is so high; it is more profitable for organizations to reclaim this product. ACR’s methodology As such, this is one of the first HCFC-22 destruction projects utilizing ACR’s methodology. Approved by the International Civil Aviation Organization (ICAO) to provide carbon credits in its Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), ACR is highly regarded across the world. Results The partnership yielded multiple environmental benefits: Emissions Avoided: The initiative successfully avoided the release of 16,000 tons of CO2-equivalent emissions by destroying HCFC-22. This substantial elimination of greenhouse gas emissions demonstrates the effectiveness of the program. Subscriber Engagement: Wren provided its subscribers with detailed updates on the impact of their contributions. These updates included data on the quantities of HCFC-22 destroyed and the corresponding emissions reductions. This transparency helped build trust and encouraged ongoing participation in climate action. Educational Impact: The collaboration raised awareness about the importance of proper lifecycle refrigerant management. Wren and A-Gas educated the public on lesser-known aspects of climate change mitigation by highlighting the environmental benefits of destroying high-GWP substances. Conclusion This partnership enabled an environmentally conscious solution for the used refrigerant By leveraging Wren's platform to mobilize individual contributions and A-Gas' technical expertise in lifecycle refrigerant management, this partnership enabled an environmentally conscious solution for the used refrigerant. It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry. refrigerant destruction protocols and technology "We are excited to work with A-Gas to push forward the standard of refrigerant destruction protocols and technology," said Landon Brand, CEO, of Wren. Landon Brand adds, "This is one of the most reliable and impactful project types we have found in our years of funding climate solutions, and we hope our community can keep blazing a trail to eliminate these dangerous refrigerants."
The Olsen Group, based in Boca Raton, Florida, is a national pioneer in HVAC energy optimization. Donald Olsen and his seasoned team of HVAC control specialists have been in business for two decades, integrating energy-saving solutions into over a thousand commercial and large-scale residential projects. In the process, the Olsen Group has become one of North America’s top suppliers of Verdant thermostats. Verdant devices leverage intelligent occupancy sensors and proprietary software to reduce HVAC runtimes by 45 percent on average. HVAC control integration Verdant’s effectiveness, reliability, and broad compatibility have made Verdant the energy management solution of choice for thousands of hotels and MDUs, including multifamily buildings, senior living, and student housing. The Olsen Group has forged a productive two-way partnership with Verdant. Donald Olsen and his team have made it a priority to share data, customer feedback, and requirements with Verdant – and Verdant, in turn, has come to rely on Olsen when they need to field test a new solution. In May of 2024, Verdant reached out to Olsen for help with a new pilot program aiming to facilitate more effective HVAC control integration, easier service, and deep energy savings for MDU projects around the globe. The Challenge Commercial VRF systems have an extremely attractive set of upsides for hotel operators Inverter (VRF) system design is becoming increasingly common in hospitality settings. Commercial VRF systems have an extremely attractive set of upsides for hotel operators. They are significantly more energy efficient and quieter than traditional VTACs or PTACs; they can provide simultaneous heating and cooling to different zones for optimal guest comfort; and they allow both individual room-level setpoint control and building-level centralized management. However, the majority of VRF units cannot connect directly to a third-party smart thermostat. Because they rely on proprietary manufacturer protocols for variable speed commands and internal diagnostics, VRF units require an external control solution to facilitate bidirectional communication with Verdant thermostats. Installation and commissioning process Every additional component in a system adds complexity and opportunity for human error. In hotels, that complexity is multiplied across hundreds of rooms. “HVAC systems are installed dark for new builds, with no power running to the site,” says Donald Olsen, President and Owner of the Olsen Group. “There’s no way to test as we go. If there are any mistakes during installation, we find out about it when the lights go on after project completion.” And mistakes are nearly inevitable. Some third-party controllers have prominent dipswitches that can be easily snagged or tripped during transportation or installation, altering their configuration and causing them to fail once the system is powered. These switches are often accidentally tripped multiple times throughout the installation and commissioning process, pioneering to a never-ending cycle of errors and service calls. VRF control solutions Adding to the issue, not all third-party control keys have the ability to retrieve and solve system error codes “Once properly configured and installed, VRF control solutions tend to be incredibly reliable,” says Olsen. “Getting them there is a real challenge, however. Accidents, human error, and repeated recalibrations can drive serious project overruns and client dissatisfaction.” Adding to the problem, not all third-party control solutions have the capability to retrieve and translate system error codes. “If the central management system isn’t getting certified manufacturer control signals from the control device, it may no longer recognize the thermostat. The system will continue to function, but it will always show up in the central manager with an error message,” warns Olsen. Airzone Aidoo Pro control solution These false error reports degrade the overall utility of the central management system, robbing operators of the ability to detect and mitigate problems proactively and requiring onsite testing to diagnose any issues. As VRF systems become the norm for hospitality projects, Verdant needed a solution to reduce the possibility of accidental misconfiguration and improve visibility into system functionality. They called on Olsen to conduct a pilot program, retrofitting sixteen VRF units in the Jacksonville Beach, FL Springhill Suites with the Airzone Aidoo Pro control solution. The Solution For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller The Jacksonville Beach Springhill Suites is a 156-room hotel with a state-of-the-art Daikin VRV rooftop chiller system. The Airzone Aidoo Pro ships preconfigured for the specific HVAC unit model, reducing the possibility for errors during initial installation. For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller. This 1:1 system design simplifies operations and troubleshooting: Any issue can be immediately traced back to a single unit, minimizing the scope and duration or repair downtime. “The Airzone Aidoo Pro offered two key upgrades as a VRV control solution,” says Olsen. “First, the dipswitches are recessed, making them much harder to trip accidentally. Second, Aidoo makes the system much easier to service. We can read error codes, run tests, and diagnose issues remotely, without ever needing to disrupt a guest’s stay.” Airzone’s expansive library This advanced remote management is enabled by Airzone’s expansive library of manufacturer protocols. “Because of our close relationship with HVAC manufacturers, Aidoo Pro can provide the proprietary control signals the central management system is expecting to see,” says Borja Fernandez, Director of OEM Solutions, Airzone. “That preserves all the features of the HVAC unit and thermostat, while also eliminating persistent false error codes. With Aidoo Pro, the central management system can function as a single-pane-of-glass HVAC monitoring and control solution for the building, as intended.” Results and Next Steps The pilot program is expanding to new builds around the globe, including projects in the UK Olsen reports that Springhill Suites is happy with their upgraded VRV system. “They have more visibility into the system and fewer services calls,” says Olsen. “When there is an issue, we can diagnose it remotely for faster resolution and less guest room downtime. It’s a much better customer experience overall.” Verdant is encouraged as well. This pilot program is expanding to several new builds around the globe, including projects in Central America, the Caribbean, the UK, and the EU. HVAC energy savings “There is a massive untapped market for energy-efficient HVAC upgrades in the Caribbean region,” says Olsen. “Energy costs there can exceed a dollar per kilowatt hour. Cost-effective devices like Verdant thermostats and the Airzone Aidoo Pro pay for themselves very easily in that scenario.” Verdant and the Olsen Group have built global brands by helping commercial properties realize significant HVAC energy savings. Through the Airzone Aidoo Pro pilot program, they are continuing to innovate, enabling reliable integration and enterprise-grade control on highly efficient VRF units. “The demand for commercial VRF control is definitely there,” says Olsen. “With Verdant and Airzone, we can deliver it with ease.”

How about 1,880 gallons of storage capacity and 2,400,000 btu/hr heating the water? Miller Electric Center The Miller Electric Center is a new state-of-the-art practice facility in downtown Jacksonville that serves as the Jaguars’ football operations headquarters. The 120 million dollar facility is 125,000 square feet and includes locker rooms, training and medical facilities, office space, and a draft room. It also features two full-size grass practice fields and one indoor field, along with shaded public viewing stands, concession areas, and a team store. Big men need big spaces Armor’s SMART TOUCH operating control makes adjusting parameters and troubleshooting a breeze Luckily, Lochinvar’s Armor Condensing water heaters are up for the job. The Armor’s stainless steel heat exchanger delivers hot water at 98% thermal efficiency and modulates at a 10:1 turndown ratio. That means the units can fire as low as 10% of their total capability and modulate up to 100% when the demand is greatest. The Jag’s facility has 3 of the AWH0800NPM units installed providing the ability to cascade which ensures the units operate with equal runtime and extends the life of the heaters. The Armor’s SMART TOUCH operating control makes adjusting parameters and troubleshooting a breeze – which is nice in Florida. Lock-Temp Round Jacketed Storage Tank With a proven storage vessel like the Lock-Temp Round Jacketed Storage Tank, making sure the stored hot water is ready for delivery is a given. These tanks have the exclusive Lock-Temp baffle that keeps water evenly stratified and the 80% draw factor allows almost the entire capacity to be used at the designated temperature. installation and commission With the help of a local manufacturers’ rep firm, Harry Warren, the installing contractor, Touchton Plumbing out of Jacksonville reported that the whole experience went off without a hitch. “The installation went extremely well, and the units have been working without fail through the first year of the facility being in use,” said Parker Touchton, project manager. The equipment was installed and commissioned according to schedule and is said to be performing as promised and at the end of a 12-hour practice, there’s no room for disappointment.
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.

The platform aims to make climate action simple and effective, ensuring that every dollar contributes to meaningful environmental change. About A-Gas A‑Gas is a world pioneer in the supply and lifecycle management of refrigerants and associated products and services. Through the first-class recovery, reclamation, and repurposing processes, we capture refrigerants and fire protection gases for future re-use or safe destruction, preventing harmful release into the atmosphere. For over 30 years, A-Gas has supported clients and partners on their environmental journey by supplying lower global warming gases and actively increasing the circularity of the industries we serve, building a sustainable future. Challenge HCFC-22 is a potent greenhouse gas with a global warming potential (GWP) much higher than CO2 The widespread use of refrigerants like HCFC-22 (R22) presents a significant environmental challenge. HCFC-22 is a potent greenhouse gas with a global warming potential (GWP) much higher than CO2 (one molecule of R22 has a global warming impact 1,810 times that of one molecule of CO2). If not properly managed, its release would have a negative impact on the atmosphere. As these refrigerants reach the end of their lifecycle, there is an urgent need for effective solutions to prevent their emissions and minimize their environmental impact. Solution To address this challenge, A-Gas recovers refrigerants for reclamation or destruction at A-Gas facilities across the country. By leveraging Wren's platform to mobilize individual contributions and A-Gas' technical expertise in lifecycle refrigerant management, this partnership enabled an environmentally conscious solution for the used refrigerant. It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry through its on-site refrigerant recovery service (Rapid Recovery®), refrigerant buyback programs, and wholesale supplier reclaim program (Refri-Claim™). HCFC-22 destruction project The ACR methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017 Wren and A-Gas formed a partnership to provide Wren subscribers with the opportunity to fund an HCFC-22 destruction project through the generation of A-Gas carbon credits to ensure the gas does not escape into the atmosphere. While the ACR (formerly American Carbon Registry) methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017, few have completed such projects because the price of HCFC-22 is so high; it is more profitable for organizations to reclaim this product. ACR’s methodology As such, this is one of the first HCFC-22 destruction projects utilizing ACR’s methodology. Approved by the International Civil Aviation Organization (ICAO) to provide carbon credits in its Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), ACR is highly regarded across the world. Results The partnership yielded multiple environmental benefits: Emissions Avoided: The initiative successfully avoided the release of 16,000 tons of CO2-equivalent emissions by destroying HCFC-22. This substantial elimination of greenhouse gas emissions demonstrates the effectiveness of the program. Subscriber Engagement: Wren provided its subscribers with detailed updates on the impact of their contributions. These updates included data on the quantities of HCFC-22 destroyed and the corresponding emissions reductions. This transparency helped build trust and encouraged ongoing participation in climate action. Educational Impact: The collaboration raised awareness about the importance of proper lifecycle refrigerant management. Wren and A-Gas educated the public on lesser-known aspects of climate change mitigation by highlighting the environmental benefits of destroying high-GWP substances. Conclusion This partnership enabled an environmentally conscious solution for the used refrigerant By leveraging Wren's platform to mobilize individual contributions and A-Gas' technical expertise in lifecycle refrigerant management, this partnership enabled an environmentally conscious solution for the used refrigerant. It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry. refrigerant destruction protocols and technology "We are excited to work with A-Gas to push forward the standard of refrigerant destruction protocols and technology," said Landon Brand, CEO, of Wren. Landon Brand adds, "This is one of the most reliable and impactful project types we have found in our years of funding climate solutions, and we hope our community can keep blazing a trail to eliminate these dangerous refrigerants."
The Olsen Group, based in Boca Raton, Florida, is a national pioneer in HVAC energy optimization. Donald Olsen and his seasoned team of HVAC control specialists have been in business for two decades, integrating energy-saving solutions into over a thousand commercial and large-scale residential projects. In the process, the Olsen Group has become one of North America’s top suppliers of Verdant thermostats. Verdant devices leverage intelligent occupancy sensors and proprietary software to reduce HVAC runtimes by 45 percent on average. HVAC control integration Verdant’s effectiveness, reliability, and broad compatibility have made Verdant the energy management solution of choice for thousands of hotels and MDUs, including multifamily buildings, senior living, and student housing. The Olsen Group has forged a productive two-way partnership with Verdant. Donald Olsen and his team have made it a priority to share data, customer feedback, and requirements with Verdant – and Verdant, in turn, has come to rely on Olsen when they need to field test a new solution. In May of 2024, Verdant reached out to Olsen for help with a new pilot program aiming to facilitate more effective HVAC control integration, easier service, and deep energy savings for MDU projects around the globe. The Challenge Commercial VRF systems have an extremely attractive set of upsides for hotel operators Inverter (VRF) system design is becoming increasingly common in hospitality settings. Commercial VRF systems have an extremely attractive set of upsides for hotel operators. They are significantly more energy efficient and quieter than traditional VTACs or PTACs; they can provide simultaneous heating and cooling to different zones for optimal guest comfort; and they allow both individual room-level setpoint control and building-level centralized management. However, the majority of VRF units cannot connect directly to a third-party smart thermostat. Because they rely on proprietary manufacturer protocols for variable speed commands and internal diagnostics, VRF units require an external control solution to facilitate bidirectional communication with Verdant thermostats. Installation and commissioning process Every additional component in a system adds complexity and opportunity for human error. In hotels, that complexity is multiplied across hundreds of rooms. “HVAC systems are installed dark for new builds, with no power running to the site,” says Donald Olsen, President and Owner of the Olsen Group. “There’s no way to test as we go. If there are any mistakes during installation, we find out about it when the lights go on after project completion.” And mistakes are nearly inevitable. Some third-party controllers have prominent dipswitches that can be easily snagged or tripped during transportation or installation, altering their configuration and causing them to fail once the system is powered. These switches are often accidentally tripped multiple times throughout the installation and commissioning process, pioneering to a never-ending cycle of errors and service calls. VRF control solutions Adding to the issue, not all third-party control keys have the ability to retrieve and solve system error codes “Once properly configured and installed, VRF control solutions tend to be incredibly reliable,” says Olsen. “Getting them there is a real challenge, however. Accidents, human error, and repeated recalibrations can drive serious project overruns and client dissatisfaction.” Adding to the problem, not all third-party control solutions have the capability to retrieve and translate system error codes. “If the central management system isn’t getting certified manufacturer control signals from the control device, it may no longer recognize the thermostat. The system will continue to function, but it will always show up in the central manager with an error message,” warns Olsen. Airzone Aidoo Pro control solution These false error reports degrade the overall utility of the central management system, robbing operators of the ability to detect and mitigate problems proactively and requiring onsite testing to diagnose any issues. As VRF systems become the norm for hospitality projects, Verdant needed a solution to reduce the possibility of accidental misconfiguration and improve visibility into system functionality. They called on Olsen to conduct a pilot program, retrofitting sixteen VRF units in the Jacksonville Beach, FL Springhill Suites with the Airzone Aidoo Pro control solution. The Solution For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller The Jacksonville Beach Springhill Suites is a 156-room hotel with a state-of-the-art Daikin VRV rooftop chiller system. The Airzone Aidoo Pro ships preconfigured for the specific HVAC unit model, reducing the possibility for errors during initial installation. For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller. This 1:1 system design simplifies operations and troubleshooting: Any issue can be immediately traced back to a single unit, minimizing the scope and duration or repair downtime. “The Airzone Aidoo Pro offered two key upgrades as a VRV control solution,” says Olsen. “First, the dipswitches are recessed, making them much harder to trip accidentally. Second, Aidoo makes the system much easier to service. We can read error codes, run tests, and diagnose issues remotely, without ever needing to disrupt a guest’s stay.” Airzone’s expansive library This advanced remote management is enabled by Airzone’s expansive library of manufacturer protocols. “Because of our close relationship with HVAC manufacturers, Aidoo Pro can provide the proprietary control signals the central management system is expecting to see,” says Borja Fernandez, Director of OEM Solutions, Airzone. “That preserves all the features of the HVAC unit and thermostat, while also eliminating persistent false error codes. With Aidoo Pro, the central management system can function as a single-pane-of-glass HVAC monitoring and control solution for the building, as intended.” Results and Next Steps The pilot program is expanding to new builds around the globe, including projects in the UK Olsen reports that Springhill Suites is happy with their upgraded VRV system. “They have more visibility into the system and fewer services calls,” says Olsen. “When there is an issue, we can diagnose it remotely for faster resolution and less guest room downtime. It’s a much better customer experience overall.” Verdant is encouraged as well. This pilot program is expanding to several new builds around the globe, including projects in Central America, the Caribbean, the UK, and the EU. HVAC energy savings “There is a massive untapped market for energy-efficient HVAC upgrades in the Caribbean region,” says Olsen. “Energy costs there can exceed a dollar per kilowatt hour. Cost-effective devices like Verdant thermostats and the Airzone Aidoo Pro pay for themselves very easily in that scenario.” Verdant and the Olsen Group have built global brands by helping commercial properties realize significant HVAC energy savings. Through the Airzone Aidoo Pro pilot program, they are continuing to innovate, enabling reliable integration and enterprise-grade control on highly efficient VRF units. “The demand for commercial VRF control is definitely there,” says Olsen. “With Verdant and Airzone, we can deliver it with ease.”
