Government

Smart choices about energy in government buildings can set a very powerful and very public example of energy efficiency and environmental stewardship. And every dollar saved on energy costs means more government funds can be diverted to other good uses, such as education, crime prevention, or national security.

New high-performance government buildings—designed to save energy and reduce environmental impact—can cost up to 50 percent less to operate than traditionally designed buildings. These buildings serve as showcases for energy-efficient lighting, building envelope features, and heating and cooling systems. They also incorporate the latest renewable energy systems, water conservation features, recycling and waste management systems, and use of environmentally sensitive building products and systems.

Existing government buildings offer similar opportunities for reducing operating costs and demonstrating innovative technologies. From firehouses and libraries to offices and police stations, government buildings can benefit from targeted energy improvements. Space heating, lighting, and water heating tend to consume the most energy in these buildings, and replacement of old boilers, lighting systems, and other inefficient systems can save up to 30 percent annually.

DOE's Federal Energy Management Program (FEMP) helps to reduce the cost of government by advancing energy efficiency, water conservation, and use of solar and other renewable energy technologies. FEMP provides guidelines and tools to help federal facilities save energy and money.

At the state and local level, state energy offices help support state government building projects, while the National Association of State Energy Officials (NASEO) provides a forum for the exchange of information and ideas. The National Conference of State Legislatures researches and advises state legislatures on various issues including energy policy. The National Association of Counties (NACo) has initiated a County Energy Efficiency Network, designed to leverage resources and provide technical assistance, localized training, support staff, and financial assistance to counties implementing cost-saving energy management strategies. NACo also supports the Public Technology Institute, an organization that helps city and county governments implement new and emerging technologies.

Energy-Saving Tips:

  • Optimize the efficiency of heating, ventilation, and cooling (HVAC) systems with more efficient boilers, motors, and variable-speed drives
  • Reduce energy and maintenance costs by installing centralized energy management systems
  • Improve indoor air quality and worker comfort with regular maintenance and cleaning of HVAC systems
  • Lower electric lighting and cooling loads and boost productivity through increased use of daylighting
  • Achieve fast returns and set a strong example by installing energy-efficient lighting

The U.S. Department of Energy (DOE) has facilitated the creation of the Commercial Building Energy Alliances (CBEAs), which are designed to minimize the energy and environmental impact of commercial buildings and reduce energy costs for these buildings.
