By now, the HVAC industry is well versed in, and operating successfully with, various HFC refrigerant production and consumption reduction schedules put forth by regulatory bodies. Under the EPA American Innovation and Manufacturing (AIM) Act, for example, the U.S. experienced a significant reduction (another 30%) in January 2024, advancing the goal of an 85% HFC phasedown from historic baseline levels by 2036. And the EU is working toward its stated objective of an HFC phaseout by 2050. technology transition rules In addition, technology transition rules are at work to limit the use of higher global warming potential (GWP) refrigerants in specific applications, ranging from commercial air conditioning to residential heat pumps. Consequently, with each passing year, the industry can expect HFC availability to feel increasingly “tighter.”  additional requirements Once the EPA’s proposed rules become final rules, more details will be available to guide the industry In addition, by the end of summer 2024, it’s expected that the U.S. EPA’s proposed rule, “Phasedown of Hydrofluorocarbons: Management of Certain Hydrofluorocarbons and Substitutes Under Subsection (h) of the American Innovation and Manufacturing Act of 2020” will be finalized—subjecting the HVACR industry to additional requirements. Once the EPA’s proposed rules become final rules, more details will be available to guide the industry on steps they need to take in terms of compliance.  takeaway from HFC phasedown The main takeaway from the progress of the HFC phasedown is that businesses at every level of the HVAC industry must employ a strong refrigerant management strategy. Several of the “Eight Rs” below represent best practices that many industry members already follow. By structuring your strategy around these measures, you can align your business with regulations and ensure you have the resources necessary to continue servicing equipment with legacy refrigerants as well as to successfully introduce A2L solutions to customers.  Eight Rs of Refrigerant Management  Regulations Whether you’re manufacturing, installing, or servicing equipment, keeping up to date with regulatory changes is key to compliance. In addition, because recent and pending regulatory changes may impact both legacy and new-generation refrigerants and equipment, understanding changes offers an important tool for planning for what’s next.  Recordkeeping Regulatory bodies conduct audits relying heavily on recordkeeping and reporting to ensure compliance Regulatory bodies conduct audits relying heavily on recordkeeping and reporting to ensure compliance. This will mainly impact manufacturers, importers, and equipment owners.  However, accurate and consistent recordkeeping on the contractor side can prove to be incredibly beneficial to your business’s operating efficiency, bring added value to your customers, and support sustainability objectives.  Repair leaks Practicing consistent, effective leak detection and repair is an important part of regulatory compliance that can also impact your bottom line by reducing service gas costs and keeping systems operating at peak efficiency. In addition, it’s the first line of defense in reducing HVAC systems’ impact on the environment.  Replace equipment As systems approach the end of their serviceable lifetime, define which new, higher-efficiency units utilizing A2L refrigerants offer the best replacements. Remind customers of benefits such as reduced energy consumption and operating costs.  Retrofits It may still make sense, where applicable, to perform a refrigerant conversion If equipment is in good condition and not nearing the end of its serviceable lifetime, it may still make sense, where applicable, to perform a refrigerant conversion. Thus allowing the equipment to operate with a more sustainable and readily available refrigerant.  Recovery The first step in supporting refrigerant circularity is recovery, which means removing refrigerant from a system and placing it into a separate container. During this process, it’s important to maintain the refrigerant’s value/purity as much as possible by not mixing gases.  Reuse/Recycle This means returning recovered refrigerant to the same system or another system with common ownership. Removing oil, moisture, or other contaminants via minor “cleanup” or filtering of the recovered gas may be part of the process.  Reclamation HFC phasedown and the transition to A2L refrigerants will continue to impact the operations of HVAC contractors Reprocessing recovered refrigerant to meet virgin purity specifications allows it to be reintroduced commercially for industry use and is becoming increasingly important in ensuring ample legacy refrigerant supply exists to meet current servicing needs. In the U.S., reclamation must be performed by EPA-certified reclaimers.  Whether it’s through new regulations or processes and requirements already underway, the HFC phasedown and the transition to A2L refrigerants will continue to impact the operations of HVAC contractors, equipment owners/operators, OEMs, equipment sellers/distributors, and others. A2L transition Implementing a solid refrigerant management strategy built around the Eight Rs can help you consistently and effectively stay updated on regulations, take steps to remain compliant, and contribute to industry efforts to mitigate global warming. In addition, following the Eight Rs can keep your company ahead of continued HFC phasedowns, aligned with the A2L transition, and in a strong position to both maintain your legacy refrigerant business and possibly expand your customer base through new-generation solutions.

Automotive HVAC is a heating, ventilation, and air conditioning system installed in automobiles, such as passenger cars, pickup trucks, and heavy-duty trucks. Like other air conditioning systems, automotive HVAC cools the air by transforming the refrigerant into a liquid or gas. The heating process, on the other hand, is characteristic of automotive HVAC as it uses the heat created by the engine.   HVAC systems in the automotive The adoption of heating, ventilation, and air conditioning (HVAC) systems in the automotive sector has been a revolutionary step in advancing automotive technology and efficiency. It has become one of the key elements in the automobile industry, given higher temperature control needs due to recent climate changes, higher consumer interest in air purification, and higher efficiency requirements fueled by the growing adoption of electric vehicles. future growth prospects Projections forecast a potential worth of $86.1 billion by 2031, driven by a significant CAGR of 5.4% Recent insights from Meticulous Research offer a glimpse of the future growth prospects of the Automotive HVAC Market. Projections forecast a potential worth of $86.1 billion by 2031, driven by a significant Compound Annual Growth Rate (CAGR) of 5.4% from 2024 to 2031.  Components of Automotive HVAC  Automotive HVAC consists of the following main components:  Compressor (Compressing refrigerant)  Condenser (Cooling refrigerant)  Receiver dryer (Removes impurities and moisture from refrigerant)  Expansion valve  Evaporator (Cools the air)  Blower (Releases the air)  Thermostat (Regulates temperature)  Actuator (Switches air direction)  Increasing Demand for Thermal Systems Features An HVAC system is equipped with air filtration and purification components that help remove pollutants Automotive manufacturers are developing HVAC systems that play a crucial role in providing comfort and managing the overall environment of the vehicles. There is a growing adoption of HVAC systems that help regulate the temperature inside the vehicle cabin, ensuring passenger comfort regardless of external weather conditions. These systems can heat the cabin during cold weather and cool it down during hot weather, providing a comfortable driving experience. Moreover, the HVAC system is equipped with air filtration and purification components that help remove pollutants, allergens, and odors from the cabin air. Compact, intelligent, and flexible solution With the increasing demand for thermal system features in vehicles, several companies are launching HVAC systems. For instance, in March 2023, SIROCO HVAC (France), an international provider of thermal and electrical solutions for industrial vehicles, launched its new 12-24V CAN/LIN bus HVAC electronic controller. This controller is a compact, intelligent, and flexible solution to manage thermal systems. With component diagnostics, short-circuit protection and a safe start-up charger, the controller offers a complete and configurable solution for HVAC components and vehicle thermal management.  Rising Adoption of Electric Vehicles According to the International Energy Agency (France), electric car sales in 2023 were 3.5 million higher than in 2022, a 35% year-on-year increase. This is more than six times higher than in 2018, just 5 years earlier. An electric vehicle's range is strongly influenced by temperature, the battery type, and what HVAC loads are required to bring the cabin to comfort.  Heating and cooling HVAC systems in an electric vehicle enhance energy efficiency and contribute to overall driving comfort Heating and cooling are some of the most significant contributors to range reduction. HVAC systems in an electric vehicle enhance energy efficiency and contribute to overall driving comfort and performance. Electric cars benefit from rapid cabin heating or hot air cooling due to the electric compressor's instantaneous response. This feature improves driver and passenger comfort, particularly in extreme weather conditions.

Modern HVAC technicians’ uniforms now integrate materials that resist wear and tear while providing flexibility and comfort. They also incorporate safety features to protect against common on-site risks, such as electrical hazards and extreme heat. Integrating these technologies elevates comfort and enhances the protection of HVAC professionals, ensuring they can perform at their best. This article focuses on the latest innovations in HVAC uniforms, focusing on the materials and technologies that are enhancing both comfort and safety for professionals in the field. The Role of Safety and Comfort in HVAC Work Comfort and safety are vital for HVAC professionals, who regularly handle extreme conditions and complex tasks. On the one hand, comfort is crucial because HVAC work often involves long hours in tight, uncomfortable spaces or in harsh outdoor climates. The job also requires frequent bending, lifting, and climbing. High-visibility options ensure workers are easily seen in low-light states, reducing the risk of mishaps Uniforms that offer adaptive comfort, such as those made from breathable fabrics that regulate temperature, can prevent overheating in the summer and provide insulation in the winter. Furthermore, durable and flexible uniforms prevent common injuries related to overexertion and repetitive motion, thereby safeguarding workers’ long-term health. This adaptability allows technicians to focus more on their work and less on the discomfort caused by their environment. Safety is equally crucial because the environments in which HVAC technicians operate are laden with potential hazards, from electrical risks to exposure to harmful chemicals, refrigerants, and gasses. Safety-focused uniforms that include features like fire-resistant materials and reinforced padding can protect against burns, cuts, and other injuries. High-visibility options ensure workers are easily seen in low-light conditions, reducing the risk of accidents. Key Materials Enhancing the Performance of HVAC Uniform Here, we explore some of the key materials that are transforming HVAC workwear: Moisture-wicking fabrics: Moisture-wicking materials are integrated into HVAC uniforms to keep technicians dry and comfortable. These fabrics draw sweat away from the body to the exterior of the clothing, where it can evaporate quickly, maintaining body temperature and reducing discomfort. Ripstop nylon: Ripstop nylon in HVAC uniforms prevents tears and abrasions from sharp objects and rough surfaces. This material ensures the uniform's longevity and the wearer's safety. Thermo-regulated textiles: These textiles help maintain a stable body temperature by incorporating materials that adapt to temperature changes. They cool the body in hot environments and insulate it in cold conditions, providing year-round comfort. Antimicrobial treatments: Antimicrobial treatments are applied to HVAC uniforms to prevent the growth of bacteria and odors. This feature is particularly important as it helps maintain hygiene and freshness, even during long working hours. Flame-resistant materials: These materials are handy when electrical hazards are present. Flame-resistant materials protect against sudden flashes of heat or direct flames, Reflective materials: These are incorporated into uniform designs for increased visibility in low-light conditions. They are essential for ensuring the safety of technicians working in dimly lit or night-time settings. Spandex blends: Spandex is often blended with other fabrics for enhanced mobility. This addition allows for a greater range of motion, which is crucial for technicians who must navigate tight spaces or perform complex maneuvers. Innovative Technologies  Innovative Technologies in HVAC Uniforms for Enhanced Safety and Comfort The following technologies are ensuring HVAC workers perform their tasks with increased efficiency and reduced risk: Smart Fabrics Smart fabrics have sensors to monitor environmental conditions and adjust the uniform's properties accordingly. This can include changes in the fabric's permeability to increase breathability or the activation of thermal elements during sudden temperature drops. Reinforced Padding Strategically placed padding protects wearers from injuries related to impacts or falls. This padding is often lightweight and designed not to restrict movement, allowing for safe and comfortable mobility even in tight spaces. UV Protection For technicians who work outdoors, UV-protective fabrics shield them from harmful ultraviolet rays, preventing sunburn and long-term skin damage. This technology is crucial for maintaining skin health during prolonged outdoor exposure. Anti-Static Features Static electricity can pose a significant risk in environments dealing with flammable substances and electrical components. Anti-static technologies in HVAC uniforms prevent static electricity buildup, reducing the risk of sparks and enhancing safety in potentially explosive atmospheres.

Eco-friendly materials: As sustainability becomes a priority, we can expect a shift toward eco-friendly materials in HVAC uniforms. Enhanced durability: New materials and manufacturing techniques will likely improve the durability of HVAC uniforms, making them resistant to tears, abrasions, and extreme conditions. HVAC Innovation A Move Towards HVAC Innovation that Balances Comfort and Safety Comfort and safety in HVAC uniforms are crucial, given the challenging environments in which technicians operate. Fortunately, current innovations in materials and technologies specifically address these critical aspects, enhancing the daily work lives of HVAC professionals. While significant strides have been made, there remains ample opportunity for further advancements. Areas such as IoT connectivity, smart textiles, and eco-friendly materials hold the potential to revolutionize HVAC workwear even further, promising a future where uniforms proactively support the health and efficiency of technicians. This forward-thinking approach ensures that as the HVAC industry advances, the workwear of its professionals will keep pace.

SNAP Rule 26 marks an important milestone in the transition from commercial refrigeration to new refrigerants. The rule lists refrigerant substitutes that provide a spectrum of technological solutions to meet required performance, global warming potential (GWP), safety, and environmental standards.  SNAP stands for Significant New Alternatives Policy, a program by the U.S. EPA (Environmental Protection Agency) under the Clean Air Act. In general, the program aims to evaluate and regulate substitutes for ozone-depleting substances, considering their overall risks to both human health and the environment. Impact of SNAP Rule 26 Final SNAP Rule 26, Protection of Stratospheric Ozone, lists acceptable substitutes in commercial and industrial refrigeration. SNAP Rule 26 will be effective July 15, 2024. The incorporation by reference of certain material listed in the rule is approved by the Director of the Federal Register as of July 15, 2024. The incorporation by reference of certain material listed in the rule is approved by the Director of the Federal Register “To date, the SNAP program has provided a very effective framework for evaluation and approval in support of innovation and the transition to new technology,” says Andrew Pansulla, Technical Service Engineer, The Chemours Company, a global chemistry company that provides a range of refrigerant products. We asked Pansulla to elaborate further on the impact of SNAP Rule 26 and what lies ahead. Q: How will the Rule’s finalization impact various commercial refrigeration sectors? Pansulla: The rule’s finalization will impact commercial refrigeration in several ways. Areas, where impact will likely be seen, include providing more acceptable refrigerant options, adherence to updated standards, new equipment design standards, and the exemption of propane from the venting prohibition for refrigerated food processing and dispensing equipment. These impacts could trigger changes in operational, manufacturing, and environmental compliance strategies in the commercial refrigeration sectors. SNAP Rule 26 will enable the adoption of the listed substitutes, including Chemours Opteon™ refrigerants, with global warming potential (GWP) lower than existing refrigerants. This rule does not require any changes to existing equipment and will impact only new equipment that uses the specific substances referenced in the SNAP rule. Q: What is the outlook for additional requirements for safe handling and use of alternative refrigerants? What specific safety standards are expected or appropriate? Pansulla: As part of the comparative risk framework used by the EPA to assess new alternatives, the EPA considers and implements use conditions that will ensure the safe use of products. These use conditions rely upon existing safety standards (e.g., UL and ASHRAE) which are available at the time the rule is finalized. In the case of SNAP Rule 26, many of the use conditions require adherence to UL 60335-2-89 and ASHRAE-15-2022. These standards are reviewed and updated periodically to maintain relevance with the products subject to the standards. Q: What are any limitations of the use of A2L refrigerants under SNAP Rule 26? Pansulla: There are two main categories of limitations under SNAP Rule 26. The first, as mentioned above, is the adherence to specific safety standards that apply to refrigerants that are designated as mildly flammable (A2L). The second is based on the GWP of the refrigerant. In the case of the A2L refrigerants subject to SNAP Rule 26, the EPA imposed conditions on the type of equipment and specific circumstances in which the substitute may be used. For example, the EPA is permitting the use of R-454A in supermarket systems, but only on the high side of a cascade system, or when the refrigerant charge capacity is less than 200 pounds. Q: Which new-generation A2L refrigerants are fit for which commercial refrigeration applications? Pansulla: Under SNAP Rule 26, the EPA deems R-1234yf, R-1234ze(E), R-454C, R-455A, R-457A, and R-516A as acceptable subject-to-use conditions for various commercial refrigeration applications. This selection is primarily driven by these refrigerants having GWPs under 150. However, certain applications necessitate refrigerants with higher GWPs due to unique performance characteristics. For example, R-454B and R-32 were listed for industrial process refrigeration with exiting fluid temperatures below minus 30 degree Celsius because these two specific refrigerants have lower boiling points than the other six less-than-150-GWP alternatives. However, it is critically important to consider the additional use conditions when designing equipment with refrigerants that have a GWP greater than 150. Q: So various equipment needs different refrigerants? Pansulla: The EPA purposefully lists several different refrigerants in each application to allow for equipment manufacturers to consider a variety of different factors that go into refrigerant selection, such as energy efficiency, capacity, normal boiling point, temperature glide, cost, safety, and use conditions. There is no one-size-fits-all solution for the entire commercial refrigeration industry. Q: How can commercial refrigeration businesses achieve a smooth transition to A2Ls? Pansulla: Keys to a smooth transition to A2Ls include understanding what refrigerants the EPA has approved as acceptable substitutes under the SNAP program, the sector-based GWP limits imposed by the Technology Transitions Program under the American Innovation and Manufacturing (AIM) Act, and which refrigerants provide the best combination of technical performance and environmental characteristics. Many resources are available to navigate the regulatory landscape and select the best low-GWP refrigerants to meet the needs of this industry. Working with companies like Chemours, who has nearly a century of refrigerant innovation and experience, is a great first step in the transition process. Q: What is the “staying power” of A2Ls — based on their chemistry, sustainability, and other attributes, combined with regulations such as SNAP Rule 26? Pansulla: The identification, selection, and development of new refrigerants that deliver required performance while meeting increasingly stringent environmental standards is a challenging process. With the identification of certain hydrofluoroolefin-based (HFO) refrigerants as an alternative to meet these criteria came a new safety classification. These HFO-based refrigerants are classified as A2Ls. While slightly more flammable than existing hydrofluorocarbon-base (HFC) refrigerants, HFOs are much less flammable than hydrocarbons, which are classified as A3 (two categories higher on the ASHRAE flammability spectrum). Moreover, such refrigerants offer an excellent alternative to substances with higher toxicity, such as R-717. The listing of A2L refrigerants in SNAP Rule 26 clearly indicates that such refrigerants can be used safely in commercial refrigeration as well as many other applications, which are subject to the SNAP Program, when adhering to the applicable safety standards.

The flammability of the new class of low-GWP refrigerants is a source of misunderstanding and unnecessary anxiety among contractors who will be working with the newer materials, which must be used by HVAC equipment manufactured beginning Jan. 1, 2025.   A2L refrigerants The newer A2L refrigerants, specifically R-454B, perform similarly to previously used materials such as R-410A, and flammability is so mild as to be almost negligible. What’s needed is more education to make contractors more comfortable with the newer refrigerants. And sensible precautions, of course.   flammability of refrigerants Among the trainers educating the industry on the benefits of, and needed precautions for, the new materials is Don Gillis, Technical Trainer of Chemours.   “The flammability part of it is the elephant in the room,” says Gillis. “Our training seeks to remove the fear of the unknown and to get ahead of what the expectations are.”  Don Gillis experience At Chemours, he is applying his real-world experience to address the practical aspects of the refrigerant transition Gillis’s background includes more than 32 years of experience in the industry, 24 of which were on a service truck. Before coming to Chemours, he was the Senior Technical Trainer for Copeland compressors where he helped to train thousands of contractors across North America.  At Chemours, he is applying his real-world experience to address the practical aspects of the refrigerant transition in hundreds of training sessions this year.   peculiarities and similarities of new refrigerants “Change is now coming so fast that technicians are struggling to keep up,” says Gillis. “We need more education, not just about the differences in the new refrigerants but also about the similarities. We need to understand the peculiarities and the similarities of new refrigerants compared to what we used in the past.”   Features of A2L refrigerants The refrigerants are safe when handled properly, offer lower toxicity, and have been used effectively around the world Working with A2L refrigerants such as Opteon XL41 (R-454B) is similar to working with R-410A. For R-454B systems, the installation and service procedures are similar. Moreover, the best practices that technicians have used for years remain applicable with A2Ls. These refrigerants are safe when handled properly, offer lower toxicity, and have been used effectively around the world to increase efficiency and reduce emissions.  When working with R-454B, processes that were once described as good practice will be required. These processes include purging a line with nitrogen to remove any residual refrigerant, testing lines under pressure for 60 minutes, and documenting the results.  training sessions Gillis is seeing higher-than-expected attendance at his training sessions this year, with actual attendance sometimes doubling what was expected. There are classes with more than 100 in attendance, even 200 and 300 in some cases. While most of the training is geared toward contractors, distributor training is similar, ensuring that the “counter people” speak the same language as their customers when it comes to the transition.   Urgency due to transition “We are not having an issue of people not coming to training,” says Gillis.  “I think right now there is a new urgency because [the transition] is happening. Dealers and distributors are telling them the new equipment is coming out, and they are peeking in to see what the hubbub is all about. We want everyone to get better. The more knowledge the better.”   R-454B refrigerant availability All equipment manufactured or imported beginning in 2025 will use newer refrigerants New equipment that uses R-454B refrigerant will be on the market within weeks. At least three original equipment manufacturers (OEMs) say they will have equipment out by the end of the first quarter. All equipment manufactured or imported beginning in 2025 will use newer refrigerants.  Misinformation Misinformation is a problem as the refrigerant transition looms, says Gillis. For example, 50 to 60% of attendees at a recent training session were still under the impression that the new refrigerants contain hydrocarbons such as propane. Not true. The flammability of A2L refrigerants more closely resembles the refrigerants currently in use than materials at the far end of the flammability spectrum.  Fact-checking and myth-busting A2L refrigerants have already been used safely for years in automobiles, window air conditioners, PTAC systems, and dehumidifiers.  “I’m all about fact-checking and myth-busting,” says Gillis. “You don’t know what you don’t know.” Some of the misunderstandings may have come from earlier messaging in the industry that addressed A2Ls along with other “flammable refrigerants” such as propane, thus confusing the matter.  Key points Key points Gillis seeks to communicate in his training sessions include:  ∙There are no hydrocarbons or propane in A2L refrigerants.  ∙Although similar to previous refrigerants, an A2L refrigerant cannot be used in an existing unit.   ∙No extra ventilation or placards are required for trucks carrying A2L refrigerants; tanks of Chemours’ Opteon XL41 (R-454B) refrigerant can be transported on their sides.   ∙The 440-pound maximum allowable refrigerant truck load stays in place.  ∙Safety and handling requirements and good installation and service practices are required.  ∙Factors such as servicing, installation, safety, pressure, temperatures, and oils are the same for R-454B as for R-410A.   To access educational resources, contractors and others may visit Opteon.com to request training by webinar, remotely, or in person. There are also YouTube videos available on demand.   training certificate Chemours provides a 2-hour certificate of attendance, with a number enabling “credit” with NATE, ACCA Although there is currently no EPA requirement for special training on the new refrigerants, the jury is out on whether a requirement might be forthcoming. There currently are also no federal or state certifications. Chemours provides a 2-hour certificate of attendance, with a number enabling “credit” with North American Technician Excellence (NATE), Air Conditioning Contractors of America (ACCA), or whomever.   high-GWP refrigerants The U.S. AIM Act will limit the amount of high-GWP refrigerants that can be made in coming years. As the manufacture of legacy refrigerants is phased out over time, existing legacy systems will need to use more reclaimed/recovered refrigerants from existing systems. Fortunately, the processes of reclamation are improving, and even refrigerant mixtures will still have value in the market moving forward. {##Poll1709537519 - What is your preferred format when it comes to training on new aspects of HVAC equipment and installation?##}

The idea of Energy as a Service involves shifting the traditional business model from selling energy as a commodity to providing a comprehensive package of goods and services to address a customer’s energy use and management. Rather than selling energy, the approach encompasses complete stewardship of a company’s energy needs in exchange for a monthly fee. Because 40% or so of a company’s typical energy needs are related to heating and cooling systems, implementing Energy as a Service (EaaS) is tied directly to a company’s HVAC systems. heat pumps and HVAC technologies In the EaaS scenario, an outside company pledges to meet a customer’s energy needs at a discount, say 5%, below what they currently pay. By then strategically seeking to lower the customer’s energy costs by more than 5%, the EaaS company uses the extra margin to pay its own costs and to attain a profit. For example, if a customer’s energy costs can be lowered by 30%, the EaaS company retains 25% every month for the term of the agreement, typically 10 years. Any costs associated with providing the service come out of the 25%. In the EaaS scenario, an outside company pledges to meet a customer’s energy needs at a discount Specifically, working to lower energy costs by that much involves an upfront investment in infrastructure, such as heat pumps and HVAC technologies, to lessen energy consumption. The idea is that the profitability of lowering energy costs will offset even a substantial investment over time. Energy-related infrastructure Briefly stated, that is the business model of Budderfly, which assumes management of a company’s energy infrastructure and becomes the “account holder” with the utility. Once an EaaS contract is signed, Budderfly then invests to upgrade the customer’s energy-related infrastructure, including LED lighting, refrigeration, etc., in addition to HVAC. The goal is to decrease energy usage by 30% or more.  Budderfly typically upgrades the variable frequency drive (VFD) When upgrading the infrastructure, Budderfly “owns” any new infrastructure assets for the term of the EaaS agreement, say 10 years, and amortizes the cost over the timespan. At the end of the term, the assets are turned back over to the customer unless they renew the contract. In the HVAC arena, Budderfly typically upgrades the variable frequency drive (VFD), economizers, and other equipment in a rooftop unit or other machinery when it takes on a new customer. Embraces the EaaS scenario EaaS has a direct incentive to invest in the newest technology to slip the client energy usage “Looking at the opportunity to save 5% of their energy costs, many customers think it seems too good to be true,” says Al Subbloie, President, CEO and Founder at Budderfly. The price of the EaaS contract is based on a two-year review of the customer’s utility bill, which creates a baseline against which the 5% discount is provided. On the consumption side, replacing a rooftop unit with a new Lennox, Carrier, or Trane high-efficiency unit can provide 30 to 40% savings in energy usage. When a customer embraces the EaaS scenario, the EaaS company has an immediate incentive to invest in the newest technology to lower the customer’s energy usage. The more they save on energy, the more they earn in profits. EaaS approach In contrast, in a business model involving energy purchased as a commodity, there is little urgency to upgrade the equipment. That explains why so much equipment currently installed is so out-of-date and energy inefficient, says Subbloie. “We did not expect the infrastructure to be so bad,” he says. “I am sharing something the world is not aware of. As long as cool and hot air are coming out of the vents, no one is looking at the energy impact.” In fact, the EaaS approach is a growing factor in decarbonization. “We are a private capital method to save the world,” says Subbloie. “We are aligning capitalism and putting it to use to save the world (from climate change),” he says. Additional investments by Budderfly Budderfly can make a profit on an EaaS contract if it can achieve 30% savings on total energy costs Subbloie says Budderfly can make a profit on an EaaS contract if it can achieve 30% savings on total energy costs. Of the 30%, Budderfly returns 5% typically to the customer and then spends about 15% on capital improvements, amortized over 10 years. Additional investments by Budderfly include 3 to 4% on technology such as thermostats, metering and controls, and data systems. Other costs are to pay Budderfly’s 300 or so employees.  In the refrigeration realm, which might account for 15 or 20% of energy usage, Budderfly deploys controllers (such as KE2 Therm Solutions and NRM) to smartly regulate the compressor operation in refrigeration units. Door alert monitors and upgraded seals avoid any leakage of cool air. Deploying R-290 (propane) refrigerant systems boosts energy efficiency. EaaS strategy When Budderfly deploys solar systems, the cost becomes just another line on the customer’s bill – there is no purchase agreement or lease involved. Budderfly is transparent with the customer in terms of the money they invest in infrastructure and other costs. In addition to providing the customer with the initial 5% discount, Budderfly also typically shares with the customer half of the proceeds of any energy savings they can achieve above 30%. The EaaS strategy is applicable to a variety of markets, but Budderfly is finding initial success in the quick-service restaurant (QSR) market, where repeatable footprints of individual locations make EaaS calculations predictable and scalable. Probably 80% of their business is in casual dining and QSR installations, including 75 or so well-known restaurant brands; they work with large franchisees who operate multiple brands. top-down relationships Budderfly also has firms in healthcare needs, nursing facilities, office buildings, amenity stores Budderfly is also working to establish “top-down” relationships at the restaurants’ corporate level, which has the ability to impose EaaS as a standard throughout its footprint. “As the climate focus becomes more important, a restaurant brand might say to do it everywhere,” says Subbloie. Hotels and motels are another vertical markets amenable to this approach, and Budderfly also has business in healthcare markets, nursing facilities, office buildings, convenience stores, and other retail. They seek to limit each building’s size to 200,000 square feet or less. Regulated and deregulated rates Budderfly has a team that handles the onboarding of new customers, which involves a short, two-page agreement. Their automated system is connected to 500 utilities, and Budderfly tracks all the regulated and deregulated rates. If rates go up, their billing increases, still based on the 5% reduction that is part of the agreement.  Budderfly benefits from its high-volume acquisition of HVAC equipment at lower prices. “We buy a lot of stuff, we have agreements to buy at volume pricing, and we are constantly negotiating to lower the price,” says Subbloie. “We buy the best of the best to achieve the greatest energy-saving outcome, for obvious reasons. We negotiate prices on the expectation that our volume will make it lucrative (for OEMs).” Subbloie says Budderfly is the largest buyer of roof-top units in the country. Energy-efficient HVAC systems Budderfly’s model enables the facility of the latest and most energy-efficient tools In the scenario of buying energy as a commodity, customers have less incentive to proactively replace their HVAC infrastructure with more efficient models. They also may not have the means to invest in capital improvements to achieve better energy efficiency outcomes. In contrast, Budderfly’s model encourages the installation of the latest and most energy-efficient equipment, and that the equipment is fine-tuned and maintained. By pushing the transition to decarbonization based on an old-fashioned business motive (i.e., profit), Budderfly seeks to jump-start the adoption of more energy-efficient HVAC systems on a large scale. “We have an economic model that is sustainable,” says Subbloie. Investment in AI Budderfly also provides customers with abundant data on their energy usage, including submetering architecture that does 20 to 40 measurements per location.  Each point of energy use reports back every five seconds, providing operational data and suggesting a possible investment in artificial intelligence (AI) to make operations even smarter.

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.

Shadow Industrial, the UK’s pioneering shortwave infrared heating specialist, recently helped St. Helen’s Chapel, in Colchester, Essex, specify and install a low-carbon heating system, keeping the congregation warm and costs down. Installing 14 of its powerful ceiling-hung and wall-mounted heaters and 16 controllers from scratch, the new system has given visitors a warm, comfortable and sustainable place to worship, whatever the weather. Futureproofing sensitively Reducing energy consumption and increasing its efficiency is a goal that touches on every part of UK business and industry, especially against the backdrop of the drive towards Net Zero 2050. It’s especially important for the UK’s Eastern Orthodox Church, which has over 250 properties nationwide. With strict and ambitious ESG commitments, futureproofing these assets in the face of tighter climate change regulation, whilst delivering their core function is a real challenge. It’s especially important for the UK’s Eastern Orthodox Church, which has over 250 properties nationwide Some of its sites are centuries old, and it can be difficult to upgrade facilities here. One particular area of concern is how to heat these large, high-ceilinged, and poorly insulated structures. Crucially, visitors need to be comfortable, but simultaneously ensure utility bills and waste are kept to a bare minimum. Warming-up the congregation It was an issue at the forefront of the church’s mind when they took over the lease of St Helen’s Chapel, Colchester, Essex in September 2020; especially as the 16th Century, Grade-II building had no existing HVAC system. The congregation bore the brunt of this unfortunate situation over three consecutive winters, where temperatures would sometimes plummet down to 1°C. It made the church a particularly uncomfortable place to worship.  Grade-II building had no existing HVAC system Initial use of oil-fired heaters proved futile, failing to provide the necessary levels of warmth and releasing a large amount of CO2. Next, industrial fan heaters were introduced, to little effect; noisy, they also proved a significant disruption to services. Following further research, they decided to trial shortwave infrared heating, approaching Shadow Industrial on the recommendation of their electrician, who had installed its solutions on previous projects. A heating revelation Shortwave infrared heating is one of the fastest-growing and most disruptive categories of heating Shortwave infrared heating is one of the fastest-growing and disruptive categories in the heating and ventilation sector. Simply, the technology works by emitting focused radiant heat through a precision-engineered smooth parabola reflector; it heats the person, not the air around them. Wall-mounted and directed downward at individuals, the energy creates a comfortable and instant warmth, mimicking the gentle heat of the sun. It’s fast becoming popular in historic ecclesiastical buildings as it’s easy to install, with limited impact on the structural fabric, in addition to its effective heating function and low energy consumption. It is also unaffected by changes in air movement, making it particularly efficacious in drafty settings such as those found in heritage sites, like St. Helen’s Chapel.  Unrivalled performance, at a reasonable price Installed in 2023, Shadow Industrial’s systems have significantly improved the comfort of congregants, allowing them to remove coats during services. The impact was particularly felt among older people and children, for whom extreme cold can have an adverse impact on health during extended services. The client was worried their tight budget would not be enough to fully equip the church’s interiors Initially, the client was worried their tight budget would not be enough to fully equip the church’s interiors with heaters. However, it proved far cheaper than traditional electric or gas central heating. The entire system and installation totaled £20,000. Putting this in context, they were initially quoted £100,000 for underfloor heating; this represents a massive 80% upfront saving, with greater performance–a no-brainer decision. The entire system and installation totaled £20,000. Shadow Industrial and its team Commenting on the project, Shadow Industrial’s founder, Steve Levy, says, “We are deeply committed to the preservation and longevity of heritage buildings. With a focus on comfort, we have successfully executed numerous heating projects with this in mind, of which St. Helen’s Chapel is the latest. It’s such an important local landmark and it was great to be able to provide a solution that benefits all those who work, volunteer, and pray here.” Father Mark Shillaker added, “Shadow Industrial’s infrared heating systems have had a transformative effect. Now visitors can worship in maximum comfort even on the chilliest winter mornings. In fact, since we’ve installed these heaters we’ve actually seen an uptick in service attendance. Many thanks to Shadow Industrial and its team for their expertise and ongoing support.” Church of England's Heat Decarbonization Plan Shadow Industrial’s electric heating systems, present a low-carbon, net-zero alternative ideal for heritage structures, churches, and culturally significant buildings. They even align with The Church of England's Heat Decarbonization Plan, offering compliance and sustainability in a non-intrusive way.

The emphasis on sustainable processes has never been greater than in today’s marketplace. Environmental conservation must be considered in every phase of appliance design and in every step of the product lifecycle.  Product designers use sustainable materials to limit carbon footprint, efficient and reliable components are chosen to reduce environmental impact during product operation, and, after the end of a product’s useful life, responsible companies must even plan for recycling and disposal.  TE Connectivity’s Industrial Technology Index, a survey of global companies focused on the innovation culture of engineers and executives, showed that innovation and sustainability are business priorities for most engineers and executives alike. Sustainable practices are now being integrated early in the innovation process, providing more opportunities to limit the environmental impact of new products. Sustainable design considerations throughout the product life cycle Sustainable Design Considerations TE’s connectors play a vital role in enabling the safe, reliable and efficient interaction of a wide variety of essential components. A growing emphasis on sustainable practices has compelled the team to develop sustainable products for various types of equipment. Designs for sustainability replace virgin materials that have large carbon footprints with recycled or renewable, biological-based alternatives.  Designs for sustainability replace virgin materials that have large carbon footprints Likewise, efficiency improvements during manufacturing, as well as more reliable, energy-saving connector designs, further limit the environmental footprint of these products. TE’s cluster block products, used for compressor applications like air conditioners, heat pumps, and refrigerators, have been redesigned with this sustainability in mind. These innovative products will help enhance the reliability of compressors, while reducing energy consumption and minimizing carbon footprint. Enhanced Safety, Performance and Productivity Reducing the temperature of connectors in operation results in less wasted energy. This can improve the performance of the compressor which translates to better appliance efficiency.  The sustainable cluster block achieves this goal with an additional contact beam, shown in Figure 2, that minimizes electrical contact resistance, optimizing the energy transmission, reducing temperature rise and providing the required connection. Additionally, the innovative lead-in alignment feature, illustrated in Figure 3, helps to error-proof the connection, improving safety as well as productivity of automated assembly processes.  The sustainable cluster block achieves this goal with an additional contact beam Potential health hazards The cluster block uses a renewable, plant-based material (Figure 4) that can be sustainably produced with minimal impact to the environment.  This high-performance material meets the stringent International Electrical Code (IEC) with flammability ratings tested to UL 94 V-0, CTI 600V and GWEPT 750°C (1380°F) no flame requirements. Made up of 50% castor bean oil, the material is halogen-free which further limits the potential environmental impact. This material reduces the carbon footprint by more than 45% during production, use and disposal while also eliminating potential health hazards.  Conversion of renewable, plant-based material into halogen-free, flame-resistant resin for the cluster block housing Minimizing environmental impact TE’s new cluster block (Figure 5) was designed to minimize environmental impact by reducing consumption of natural resources, minimizing waste and promoting renewable energy. To mitigate climate change, the cluster block connector features 19% lower plastic usage and 26% lower metal usage, when compared to legacy connectors (Figure 6).  The cluster block connector features 19% lower plastic usage and 26% lower metal usage The sustainable cluster block will help TE contribute to maximizing the safety, performance and sustainability of compressor applications. This technology is a key step in meeting the growing demand for cost effective, environmentally friendly solutions that are compatible with modern automated assembly processes. As the appliance industry continues to evolve, sustainable connector designs will undoubtedly play a key role in shaping the future of compressor applications and beyond.
