The U.S. Department of Energy (DOE) issued a rule aimed at ensuring federal buildings use proper energy certifications.

The rule, which goes into effect November 13, ensures that in cases where agencies choose to use green building certification systems to meet federal sustainability and energy standards, they must select a system that verifies enhanced energy efficiency from private-sector certifications such as Leadership in Energy and Environmental Design (LEED).

“By requiring re-assessments at least every four years, the rule will ensure energy … savings continue well beyond the initial building opening or retrofit,” the DOE officials wrote in a statement. “System requirements for the verification of energy … performance in new construction and major renovations will lead to reduced consumption through active energy … management.

The DOE officials say the considered use of green building rating systems will advance the performance of federal buildings by focusing on modernized, integrated building systems that minimize inefficiencies and waste.

According to a statement, the DOE will provide a webinar to further discuss requirements in November.
