Key Points

This bill adds mechanical insulation to the list of official energy and water saving tools used in federal buildings. Mechanical insulation includes materials used to wrap pipes, boilers, and heating and cooling systems to stop heat or cold from escaping.
Federal agencies would be required to look for opportunities to install this insulation during their regular building energy audits. The goal is to reduce energy waste and lower utility costs for government-owned facilities.
The insulation must meet specific industry standards for quality and performance. By keeping pipes and machines at the right temperature, the government can save money on utility bills while putting less strain on its equipment.
