The Department of Energy's Opportunity for Energy Savings Through the Use of Setbacks in its Facilities
During 2008, the Department of Energy expended about $300 million to provide energy to over 9,000 Federal buildings at its facilities. A significant portion of those costs, up to 40 percent, were expended for heating, ventilation and air conditioning (HVAC). Because of its size and scope, operating the Department's existing HVAC systems as efficiently as possible offers the promise of immediate and substantial energy and cost savings. In addition to the "common sense" reasons for efficient and economic energy use, Federal agencies are specifically required to conserve energy by reducing heat or eliminating air conditioning during non-working hours.
