Center for Building Knowledge

As part of CBK’s work for the Department of Energy Building America Program, the Center  is researching  New Jersey’s Home Performance with Energy Star (HPwES) program to determine which packages of energy efficiency measures are  achieving 30% energy savings or greater in existing homes. The Center will work with the New Jersey Clean Energy Program, and Public Service Electric and Gas (PSE&G) to evaluate the specific measures implemented in 50-100 homes that have achieved measured energy savings of more than 30%. Measurements will be based on utility bill data, not modeled savings. The Center will also look at the return on investment (ROI) of the packages using measure implementation costs from the homes. This project will identify the most common packages that achieve 30% or greater energy savings in existing homes.
