In answer to your question, the Federal Buildings Initiative has existed since 1991 and uses energy performance contracts, eco-energy service contracts, in order to assist departments to undertake energy-efficient upgrades in their buildings without having to spend money. Companies such Amaresco, energy efficiency companies, come and do the upgrades and are paid out of the energy savings generated through the upgrades.
Since 1991, 7,500 buildings, or 88 projects, have been upgraded. Some projects are extensive and include several buildings. That has generated private sector investments of approximately $265 million and has generated savings of $38 million per year, because those savings are cumulative. That is one method. This program encourages departments and provides them with the necessary tools to act. It assists them in using energy performance contracts with these companies in order to help them carry out these energy efficiency upgrades.
