Section 103A.8A. Energy conservation requirements.

  The state building code commissioner shall adopt as a part of the state building code a requirement that new single-family or two-family residential construction shall comply with energy conservation requirements. The requirements adopted by the commissioner shall be based upon a nationally recognized standard or code for energy conservation. The requirements shall only apply to single-family or two-family residential construction commenced after the adoption of the requirements. Notwithstanding any other provision of this chapter to the contrary, the energy conservation requirements adopted by the commissioner and approved by the council shall apply to new single-family or two-family residential construction commenced on or after July 1, 2008, and shall supersede and replace any minimum requirements for energy conservation adopted or enacted by a governmental subdivision prior to that date applicable to such construction. The state building code commissioner may provide training to builders, contractors, and other interested persons on the adopted energy conservation requirements.
