More Stringent Energy Efficiency Standards for Packaged Terminal Air Conditioners
The Department of Energy has adopted more stringent mandatory minimum energy efficiency standards for standard-sized packaged terminal air conditioner equipment. The new standards for PTAC equipment are equivalent to the standards in American National Standards Institute / American Society of Heating, Refrigerating, and Air-Conditioning Engineers / Illuminating Engineering Society Standard 90.1-2013. The DOE has also determined not to amend the current energy conservation standards for packaged terminal heat pump equipment, which are already equivalent to the PTHP standards in ANSI/ASHRAE/IES Standard 90.1-2013. The agency has determined that adoption of PTAC and PTHP standards more stringent than ANSI/ASHRAE/IES Standard 90.1-2013 is not economically justified.
Compliance with the amended standards established for standard-sized PTACs will be required from Jan. 1, 2017.
