The benefits of energy efficiency extend beyond energy savings. Homes, commercial buildings, and industrial facilities gain comfort, health, and safety benefits from energy efficiency programs. Additional benefits for businesses include savings on maintenance, materials, and the costs of regulatory compliance. On the supply side, electric utilities enjoy reduced system costs. Focusing on the residential, business, and utility sectors, this report examines each of these multiple benefits, their role in program marketing, and current best practices for including them in cost-effectiveness testing.

This report analyzes and develops estimates of non-energy impacts that could be included in cost effectiveness analyses for the EmPOWER Maryland energy efficiency programs. Four non-energy benefits are included in this analysis: air emissions, comfort, commercial operations and maintenance (O&M), and utility bill arrearages. In all four cases, a recommended value and methods for including them in future EMPOWER costs effectiveness analyses are provided.

On Maryland's Home Performance with ENERGY STAR website, homeowners can review their contractor and experience. These customer reviews, along with contractors' accreditations and services, are published on the website as part of each contractor's information page. Users of the website can search for contractors and sort the results based on homeowner ratings and by geographical location.
