BESO Requirements:

Energy Efficiency Assessment
BESO requires building owners and homeowners to complete and publicly report comprehensive energy assessments to uncover energy saving opportunities. The assessments are conducted by registered energy assessors who provide tailored recommendations on how to save energy and link building owners to incentive programs for energy efficiency upgrade projects, such as Energy Upgrade California. Energy efficiency improvements are voluntary and encouraged. BESO is required prior to sale of a house or whole building under 25,000 square feet, and on a phased-in schedule for multifamily and commercial buildings.

BESO Energy Assessments Reveal Individualized Energy Improvement Opportunities

Developed by the Department of Energy and its national laboratories, the Home Energy Score™ provides home owners, buyers, and renters directly comparable and credible information about a home’s energy use. Like a miles-per-gallon rating for a car, the Home Energy Score is based on a standard assessment of energy-related assets to easily compare energy use across the housing market. We utilize this assessment for BESO compliance.
