The New Jersey Clean Energy Program (NJ CEP) promotes energy efficiency and the use of clean, renewable sources of energy. The Residential Construction Program, known as the New Jersey ENERGY STAR Homes Program, furnishes technical assistance and financial incentives to builders who commit to construct new homes to the standards established by the ENERGY STAR Homes Program. APPRISE conducted an impact evaluation of the New Jersey ENERGY STAR Homes Program as a subcontractor to KEMA. The evaluation found that ENERGY STAR Homes achieved the gas energy savings that were projected by the REM/RateTM model and achieved about three fourths of the air conditioning electric savings that were projected by the REM/RateTM model.
However, the net program impacts for the 2005 and 2006 ENERGY STAR Homes were considerably smaller than the gross program impacts. While ENERGY STAR Homes used considerably less gas and electricity than the REM/RateTM Reference Homes, the differences between ENERGY STAR Homes and Comparison Homes that are built without ENERGY STAR incentives were considerably smaller than the differences projected by the REM/RateTM model.
