Mandatory Measures were established to set minimum requirements for energy efficiency performance for all residential buildings in California. Mandatory Measures govern efficiency requirements, which apply to envelope insulation values, lighting, space and water heating systems, ducts, and others. As Chris Olvera from the California Energy Commission clarifies, Mandatory Measures are required features, regardless whether the prescriptive or performance method were used to demonstrate compliance. The MF-1R form has changed for the 2008 Energy Efficiency Standards, and now serves as a summary of the Mandatory Measures that should be included on the plans. In addition, there are several new Mandatory Measures under the 2008 Standards.
