On Dec. 17, 2015, the U.S. Department of Energy (DOE) finalized new negotiated energy conservation standards for commercial air conditioners, heat pumps, and commercial warm-air furnaces, otherwise known as rooftop units (RTUs).
The effective date of this rule is July 1, 2016. The final rule changes will be mandatory for representations of energy use or efficiency on or after November 28, 2016.
DOE has rescheduled its public meeting regarding the notice of proposed rulemaking for portable air conditioners to Wednesday, July 20, from 9 a.m.-4 p.m. in Washington, District of Columbia.
