The Database for Energy Efficient Resources (DEER) contains information about selected energy-efficient technologies and measures. DEER provides estimated energy-savings potential for many technologies and measures in residential and nonresidential applications. It has both typical measures--those commonly installed in the marketplace--and more energy-efficient ones. Energy-efficient measures provide the same service as the standard/code technology, but consume less energy--at a slightly higher purchase price.
