Copeland Commercial & Residential Solutions, Efficiency and Regulations
With a primary interest in regulatory changes impacting commercial and residential HVAC systems, Jennifer discusses current and future codes, standards, and regulations, and provides insight on how they affect homeowners, facility managers, and contractors.
Previously we have looked at federal minimum energy efficiency levels and the metrics used today to rate air conditioning systems (such as SEER, integrated energy efficiency ratio, or full load EER). Now we are shifting focus and looking at system efficiency and where it is headed in the future.
As a contractor, it is important that you are aware of the different federal minimum efficiency levels and compliance requirements across regions. Understanding the new standards and metrics (SEER2, EER2, HSPF2) will help both you and your clients feel confident moving forward with these changes.
The purpose of the American Innovation and Manufacturing (AIM) Act is to phase down HFC, or hydrofluorocarbons, production and consumption by 85% over the next 15 years, and support a transition to more environmentally and consumer-friendly cooling technology options. HFCs will continue to be available for existing equipment, but the EPA will establish requirements for managing any existing HFC in use.
Before buying a new air conditioner, homeowners can make more informed decisions by knowing the latest standards and efficiency ratings. While more efficient equipment is typically more expensive to purchase on the front end, homeowners that understand the value of more efficient operating systems are able to realize energy cost savings that can actually offset the difference in the system’s original purchase price.
As global, national, and state regulations have targeted the phase-down of HFCs, the industry has seen a shift toward alternative refrigerants with lower global warming potential (GWP). While more environmentally friendly, many of these emerging options bear a degree of flammability.
Refrigerant regulations are coming – the question is when and how, and that depends on the state in which you do business. Read on for more information.
Since the EPA began regulating hydrofluorocarbon (HFC) refrigerants in 2015, the industry has made significant progress in identifying the next generation of refrigerants. However, the events of the past year have left the timing of the transition uncertain.
Congress has reinstated federal tax credits for residential and commercial geothermal heating and cooling systems. Learn how to claim your tax credit below.
