What kinds of projects trigger the stretch energy code?
New construction and renovations of residential buildings three stories or less would be subject to the residential portion of the stretch energy code. New construction projects would be required to use the Home Energy Rating System (HERS) and achieve an index level of 65 if the building is over 3,000 square feet in area or 70 if the building is smaller (see attached table).

Renovation projects would have 2 options:
  • The performance approach requires achieving a HERS rating of 80 for homes over 2,000 square feet and 85 for those under 2,000 square feet.
  • The prescriptive approach requires measures listed by the Energy Star for Homes Program, such as more efficient equipment, plus insulation at least equal to that required by the International Energy Conservation Code (IECC) 2009 code.
