Federal Mechanical Insulation Act

119th Congress Introduced May 15, 2025

Summary

What This Bill Does

The Federal Mechanical Insulation Act amends National Energy Conservation Policy Act section 543. It defines mechanical insulation property as insulation materials, facings, and accessory products placed in service in connection with a mechanical system, meeting or exceeding ASHRAE Standard 90.1 as in effect on enactment, and reducing energy loss from that system. It also changes Federal comprehensive energy and water evaluations so they must identify energy- and water-saving measures, including installation of mechanical insulation property when applicable. The bill does not mandate every Federal building to install insulation, but it makes mechanical insulation a required consideration in Federal facility efficiency evaluations.

Who Benefits and How

Mechanical insulation manufacturers benefit because Federal evaluations must look for qualifying insulation opportunities. Mechanical insulation installers benefit from potential Federal building retrofit work tied to energy and water evaluations. Federal facility energy managers benefit from a clearer statutory category for mechanical-system energy-loss reductions. Energy service companies benefit if more Federal projects include insulation measures. Federal taxpayers may benefit if identified projects reduce energy waste and utility costs over time.

Who Bears the Burden and How

Federal building managers must include mechanical insulation property in applicable comprehensive energy and water evaluations. Federal facility evaluators must check ASHRAE Standard 90.1 compliance and determine whether insulation measures reduce mechanical-system energy loss. Federal building contractors must document qualifying materials, facings, accessory products, and installation conditions. Agencies may face upfront project costs if evaluations identify cost-effective insulation work.

Key Provisions

  • Defines mechanical insulation property for Federal building energy-efficiency law.
  • Requires qualifying insulation materials to be connected to mechanical systems and meet or exceed ASHRAE Standard 90.1.
  • Requires qualifying insulation to reduce energy loss from the mechanical system.
  • Amends Federal comprehensive energy and water evaluations to identify mechanical-insulation measures when applicable.
