Implementation Schedule Notes

  1. All low–income projects financed through low–income housing agencies may earn the ENERGY STAR under the CA Version 2 Program Requirements as long as the application for funding for those homes was received by the low–income housing agency before January 1, 2012 and the housing project includes at least one unit reserved for low–income tenants. If the application for funding is received between January 1, 2012 and September 30, 2012, then the homes must earn the ENERGY STAR under the CA Version 2.5 Program Requirements and under the Version 3 Program Requirements if application for funding is received on or after October 1, 2012.
  2. The Rater may define the ’permit date’ as either the date that the permit was issued or the date of the contract on the home. In cases were permit or contract dates are not available, Providers have discretion to estimate permit dates based on other construction schedule factors. These assumptions should be both defensible and documented.
