Summary

Adds a new statutory definition of “mechanical insulation property” to the National Energy Conservation Policy Act and requires that mechanical insulation be treated in the Act’s comprehensive energy and water evaluations. The definition ties eligible insulation to materials, facings, and accessory products placed in service with a mechanical system that meet or exceed ASHRAE Standard 90.1 (as of enactment) and that reduce energy loss. The section also amends the statutory provision governing comprehensive energy and water evaluations, although the precise text of that insertion is not provided in the summary you supplied.

Key Points

• Creates a statutory definition of "mechanical insulation property" tied to ASHRAE Standard 90.1 (edition at enactment).
• Requires or clarifies that mechanical insulation be considered in comprehensive energy and water evaluations under the National Energy Conservation Policy Act.
• Limits eligible products to insulation materials, facings, and accessory products installed with a mechanical system that reduce energy loss.
• Does not provide new funding or specify an effective date in the provided summary.
• Primarily affects federal facility energy assessments, procurement, and project planning for mechanical systems and insulation.
• Links statutory compliance to a specific industry standard (ASHRAE 90.1 as of enactment), creating a clear technical baseline.
• Likely increases emphasis on insulation performance in retrofit and efficiency projects, benefiting efficient-product manufacturers and installers.
