(This measure has not been amended since it was introduced. The summary of that version is repeated here.)
Directs the Secretary of Energy (DOE) to submit a report within one year on the impact of thermal insulation on both energy and water use systems for potable hot and chilled water in federal buildings and on the return on investment of installing the insulation. Requires the report to include: (1) an analysis based on the cost of municipal or regional water for delivered water and the avoided cost of new water; and (2) a summary of energy and water savings, including short-term and long-term (20 years) projections of such savings.
