HR 3474 Re-checks Congress.gov for new actions and updates the bill's status, and fills in any sponsors, committees, or related bills that are missing. It does not re-pull sponsors/cosponsors/committees/related — those rarely change — and it skips all work if nothing has changed upstream, so it's cheap to click.
Federal Mechanical Insulation Act
H. R. 3474 To clarify that the installation of mechanical insulation property is an energy or water efficiency measure that may be used in Federal buildings for purposes of section 543(f) of the National Energy Conservation Policy Act, and for other purposes.
Summary
This bill amends the National Energy Conservation Policy Act to clarify that installation of mechanical insulation on pipes and equipment in Federal buildings is an energy efficiency measure that can be used to improve building efficiency. The bill defines mechanical insulation property as insulation materials placed on mechanical systems that meet industry standards and reduce energy loss. The bill requires Federal building energy and water evaluations to specifically identify mechanical insulation installation as a potential energy-saving measure. The bill allows Federal agencies to use mechanical insulation projects as part of their energy and water efficiency improvements.

Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled,
SECTION 1. SHORT TITLE.
This Act may be cited as the “Federal Mechanical Insulation Act”.
SEC. 2. INSTALLATION OF MECHANICAL INSULATION PROPERTY AS AN ENERGY OR WATER EFFICIENCY MEASURE IN FEDERAL BUILDINGS.
