San Francisco Mandates Commercial Building Energy Benchmarking, Audits
In February 2011, San Francisco approved ground-breaking green building legislation that will improve energy efficiency in existing buildings. The Board of Supervisors passed an ordinance codifying the recommendations of the Existing Commercial Building Task Force.
Under the ordinance, non-residential building owners would be required to benchmark the energy use of their buildings and disclose the results annually to the city and, thereby, the public. The next phase of the ordinance requires building owners to conduct energy audits, starting with commercial properties larger than 50,000 square feet in October 2011. By 2013, the rules would apply to all commercial properties 10,000 square feet or larger.
