Federal Mechanical Insulation Act

The bill directs federal agencies to identify energy saving and water saving measures, such as the installation of mechanical insulation property, in certain annual energy and water evaluations of federal buildings. Thus, the bill allows the installation of mechanical insulation property (e.g., thermal insulation) to be considered an energy or water efficiency measure that may be used in federal buildings under the National Energy Conservation Policy Act.
