California: First State to Mandate Disclosure of Energy Use at Time of Building Transaction
California is the first state to mandate disclosure of commercial buildings’ energy use to prospective buyers, lessees, or lenders, and it is requiring building owners to use the EPA ENERGY STAR online tool, Portfolio Manager, to get the job done. A new California law, Assembly Bill 1103, requires all commercial building owners or operators to disclose their buildings’ benchmarking data and Portfolio Manager performance rating to prospective buyers, lessees of entire buildings, or lenders starting in 2010. The state also has broken new ground by requiring all state-owned buildings to be benchmarked with Portfolio Manager.
