This bill amends the Energy Conservation and Production Act to modify the process for updating federal building energy efficiency performance standards. It mandates that within one year of new ASHRAE or International Energy Conservation Code revisions, the Secretary must determine whether to update federal standards based on several new criteria. These criteria include evaluating the cost-effectiveness , technological feasibility , and potential impact on electric grid reliability of proposed requirements. The Secretary must also consider how directly the requirements relate to energy efficiency and if they would necessitate a building transitioning to a different energy type or source. Significantly, if an amendment would require a building to switch from consuming fossil fuel-generated energy to another source, this must be weighed as a negative factor when deciding whether to update the federal building energy efficiency performance standards.
