After extensive research, testing, and evaluation, Johnson Controls, the provider of smart, healthy, and sustainable buildings, has selected R-454B, a lower global warming potential (GWP) refrigerant, to replace R-410A in its ducted residential and commercial unitary products as well as air-cooled scroll chillers. Systems using the new refrigerant will be available for Johnson Controls, YORK®, Luxaire®, Coleman®, Champion®, TempMaster®, Fraser-Johnston®, Guardian®, Evcon™, and Quantech® branded products in North America, as well as specific international markets where codes are in alignment. High-GWP refrigerants This decision was made as the HVAC industry is preparing to phase out high-GWP refrigerants, such as R-410A, which are now being formally addressed by the Environmental Protection Agency (EPA) through the recently passed American Innovation and Manufacturing (AIM) Act. The AIM Act directs the EPA to phase down U.S. hydrofluorocarbon (HFC) production and use by approximately 85 percent over the next 15 years. Johnson Controls has determined R-454B be the best-in-class replacement refrigerant After evaluating several low-GWP alternatives on a variety of performance and market metrics, such as safety, capacity, efficiency, reliability, availability, and longevity, Johnson Controls has determined R-454B to be the best-in-class replacement refrigerant – a decision echoed by other HVAC manufacturers. R-454B has the lowest EPA SNAP approved GWP for unitary applications of all ASHRAE classified A2L (low-toxicity, mild flammability) refrigerants on the market, coming in at 466. Maximizing environmental benefits This is one-fifth the GWP of R-410A, far lower than the pending 750 GWP limits being proposed and offering the longest-term viability. “Utilizing R-454B was a clear decision, but one that took years of in-depth research, testing, and evaluation,” said Chris Forth, Executive Director of regulatory, codes, and environmental affairs, Ducted Systems, Johnson Controls. “This decision maximizes environmental benefits, which will help to avoid, if not completely avert, a second, near-term transition for the unitary sector. As the AIM Act phase-down schedule progresses, higher-GWP fluids such as R-32, while viable today, have the potential to be eliminated as an option due to their high-GWP values. Johnson Controls will continue to evaluate lower-GWP alternatives for future possibilities.” Improving system efficiency Existing R-410A equipment built prior to that date can be sold and installed indefinitely" In addition to reducing environmental impact, R-454B is more compatible with existing R-410A equipment designs, requires a less or similar refrigerant charge, and can reduce the energy use of HVAC systems and improve system efficiency. The similar operating characteristics with R-410A will make for a smoother transition for distributors, wholesalers, and contractors. “It’s important to note that these pending mandates from the EPA and the California Air Resources Board (CARB) would only apply to the sale of new residential and commercial unitary equipment as well as air-cooled scroll chillers. As the pending regulations stipulate a specific manufacturing cutoff date of January 1, 2025, for residential and light commercial unitary products and January 1, 2024, for air-cooled scroll chillers, existing R-410A equipment built prior to that date can be sold and installed indefinitely,” said Forth. Rule-Making processes “EPA and CARB are scheduled to begin their formal rule-making processes this year, which will determine how long of a servicing period will be granted for R-410A equipment currently in service.” As we approach the refrigerant transition cutoff dates, safety standards and building codes must be updated prior to a widespread market introduction of mildly flammable, low-toxicity A2L refrigerants such as R-454B. Extensive, multi-year research and testing have been conducted by ASHRAE, AHRTI, and others to ensure A2Ls can be safely deployed. Proper training will be critical to ensure the safe use, transportation, and storage of A2L refrigerants. Johnson Controls is committed to ensuring the safe transition to R-454B by providing in-depth training for its contractors and technicians prior to the pending refrigerant transition dates.
Johnson Controls, a global provider of smart, healthy, and sustainable buildings, is leading the charge on sustainable manufacturing with its continued commitment to green energy. The company’s 1.3 million square-foot HVAC manufacturing plant in Wichita, KS, is now powered by 100 percent wind energy. The plant manufactures residential heating and air conditioning equipment for the YORK, Luxaire, Coleman, and Champion brands. With this switch to renewable energy, the plant’s electricity is offset by zero carbon electricity, which represents 19 percent of Johnson Controls U.S. manufacturing electricity consumption. local wind power “With the Wichita plant now operating on 100 percent local wind power, this is not only a major achievement for Johnson Controls, but also the community. This change has dramatically reduced emissions and the plant’s environmental impact for many years to come,” said Joe Oliveri, Vice President and General Manager, Global Ducted Systems, Johnson Controls. “This is a prime example of Johnson Controls commitment to sustainability and a healthier planet.” Johnson Controls Wichita plant is receiving its wind energy from Evergy’s Soldier Creek Wind Farm, a 300-megawatt wind farm in Nemaha County, Kansas, that was completed in November 2020. The energy cost savings projections from the wind power agreement are expected to be approximately $2.7 million over the life of the 20-year contract - the equivalent of taking 100,000 passenger vehicles off the road. improved capacitor banks Evergy applauds Johnson Controls leadership in sustainability by using local, renewable energy" In addition, Johnson Controls will be installing improved capacitor banks to more efficiently consume the plant’s wind energy. This will lower the plant’s energy consumption by nearly 5 percent, equaling an additional energy savings of $3 million over the next 20 years. “Evergy applauds Johnson Controls leadership in sustainability by using local, renewable energy,” said Jeff Martin, Vice President, Community and Customer Operations, Evergy. “This commitment helps grow wind development in our area, driving investment in local communities and creating green jobs.” renewable electricity usage Since 2017, Johnson Controls reduced its GHG emissions intensity by 26 percent and energy intensity by nearly 6 percent. Building on this history of success, in 2021, Johnson Controls set new ambitious environmental sustainability commitments such as aiming to achieve zero carbon emissions before 2040 as well as reducing the company’s operational emissions by 55 percent and reducing customers’ emissions by 16 percent before 2030. In addition, the company aims to achieve 100 percent renewable electricity usage globally by 2040.
