An annual ENERGY STAR benchmarking must be performed for commercial buildings 10,000 square feet and greater and disclosed annually via a public website. The ordinance requirements will be phased in over 3 years (beginning 2011) based on building size. In addition, ASHRAE level II audits are required for commercial buildings 50,000 square feet and greater and ASHRAE level I audits are required for buildings 10,000 square feet to 49,999 square feet. These audits are required once every 5 years. The initial compliance schedule is still in progress. Results are reported to the city. There are exemptions for Leadership in Energy and Environmental Design Existing Building (LEED ED) certification (Green Building rating system for existing buildings) or multiple ENERGY STAR labels.
