Title: Energy Conservation Standards for Variable Refrigerant Flow Multi-Split Air Conditioners and Heat Pumps 

As required by the Energy Policy and Conservation Act, as amended (EPCA), the U.S. Department of Energy (DOE) is conducting this rulemaking to consider amended energy conservation standards for a certain category of Commercial Package Air Conditioning and Heating Equipment found at 10 CFR 431.97, specifically those for variable refrigerant flow multi-split air conditioners and heat pumps (VRFs). Under the statute, DOE is required to either: (1) establish an amended uniform national standard for this equipment at the minimum level specified in the amended ASHRAE Standard 90.1; or (2) adopt a more-stringent standard, if supported by clear and convincing evidence. To adopt a more-stringent standard, the Secretary must determine, by rule published in the Federal Register, that adoption of such standard for this equipment would result in significant additional conservation of energy and is technologically feasible and economically justified.
