CALRESEST
The California Residential Efficiency Saturation Tool
 

The California Lighting and Appliance Saturation Study database provides baseline information on residential appliance, equipment and lighting saturations and efficiencies. The original study was completed in 2000. An update was completed in 2005. The overarching goal for the studies is to provide an accurate baseline in order to understand future energy savings potential and past accomplishments in the residential sector.
 
The tool was created so that utility program planners, evaluators and other interested parties can query the databases online. It calcualtes all averages to reflect the characteristics of interest and the underlying sampling, so that the resulting statistics are representative of the population of residences in California. The software also calculates sample sizes and error bounds (at the 90% level of confidence). Those interested in viewing the data need only create a free account by following the links below.
