Summary 

The Northwest Energy Efficiency Alliance (NEEA) and Center for Energy and Environment (CEE) contracted with Resource Innovations and A2 Efficiency to conduct this analysis. A project committee — comprising NEEA, CEE, Resource Innovations, A2 Efficiency, and Nicor Gas (Nicor) — was formed to define the research scope and modeling methodology. 

This research assessed 15 efficiency measures in 11 locations, representing climate zones across the United States in order to evaluate each measure. Building off previous modeling work, this research is intended to support program development and implementation of codes and standards.
