The original Waxman – Markey climate change bill had proposed a National Energy Efficiency Code. That same proposal appeared in the Senate’s first American Clean Energy Leadership Act (ACELA). In both versions there were specific energy efficiency targets, timelines, adoption and implementation plans, and enforcement plans. However a recent draft of the Kerry-Boxer Senate bill has no such specifics, no mandated energy efficiency savings and no information on implementation. (see Section 174, page 113). The Kerry-Boxer bill simply states a mandate that the Department of Energy or “other agency head or heads as may be designated by the President” shall promulgate regulations establishing building code energy efficiency targets.. beginning not later than January 1, 2014. It also states that “such regulations shall be sufficient to meet the national building code energy efficiency targets.. in the most cost-effective manner and may include provisions for State adoption of the national building code standards and certification of state programs.
