Businesses that implement energy efficiency improvements often enjoy other benefits besides utility bill savings. However previous efforts to measure multiple benefits have been sporadic and far from rigorous. Still, evidence suggests that including non-energy impacts can reduce the payback time of some energy efficiency improvements by 50% or better. This report draws on expert interviews and a synthesis of existing literature to describe energy efficiency’s multiple benefits to business enterprises. Including non-energy benefits can strengthen the case for business investment in energy efficiency and also contribute to the cost-benefit screening of regional energy efficiency programs.
