The bill amends federal energy law to officially recognize insulation on mechanical systems, such as pipes, ducts, and heating or cooling equipment, as an approved energy or water efficiency measure. It adds a definition requiring the insulation to meet industry standards set by ASHRAE and to reduce energy loss. It also requires federal agencies to specifically evaluate this insulation as an option during their regular building energy and water assessments.
The bill affects federal agencies that own or manage government buildings, along with contractors and companies that manufacture or install mechanical insulation products.
Requiring agencies to consider insulation upgrades during evaluations could lead to more federal buildings adopting this measure, changing standard assessment practices for facility managers and inspectors.
