Residential Lighting Evaluation Hours of Use (HOU) Studies - EM&V Methods and Results

NEEP dove deeply into savings assumptions as found in Technical Reference Manuals (TRMs) throughout the region to understand what values were being used for key metrics such as hours of use, delta watt, and measure life.  In Appendix B, NEEP provides the opportunity to view completed Standardized Methods Forms to compare evaluation methodology and results. This brief is intended to help states understand key similarities and differences in various parameter assumptions, where and why some are warranted, and where there may be opportunities for improved consistency across the states.
