The first Internet-based tool for calculating energy use in residential buildings -- the Home Energy Saver website -- helps consumers identify the best means and resources to save energy in their homes. The project, developed at Berkeley Lab by researchers in the Environmental Energy Technologies Division, was initiated by the U.S. Environmental Protection Agency as part of the national Energy Star program for improving energy efficiency in homes. The program is operated by the EPA and the U.S. Department of Energy.
Users can use the site to quickly compute their home's energy use based on different variables, such as heating, cooling, major appliances, and lighting. The computer estimates how much energy and money can be saved and how much pollution can be prevented by implementing energy-efficiency improvements.
The website also offers instant comparison of energy use in 11 parts of the country and can calculate energy use in a particular city based on a detailed description of the home provided by the user.
A reference ("Librarian") page connects users to a large array of related resources on the Internet, including product information, residential utility programs, energy software, home energy rating systems, financing information, and much more.
Finally, a FAQ page provides answers to frequently asked questions such as:
