(i) which is constructed in accordance with the standards of chapter 4 of the 2006 International Energy Conservation Code, as such Code (including supplements) is in effect on January 1, 2006, and
(ii) for which the heating and cooling equipment efficiencies correspond to the minimum allowed under the regulations established by the Department of Energy pursuant to the National Appliance Energy Conservation Act of 1987 and in effect at the time of completion of construction, and
