"Ask Adam" Adam has been in the HVAC industry for over 40 years. He has been involved in all aspects of the business from service to sales. His main interest is in customer comfort. How Has Energy Conservation Affected New Construction? Adam Kern, Owner Official Heating & Cooling In a continuous effort to maximize energy savings in new homes, various code changes have taken place. Codes vary throughout the country based on different climate zones, but conceptually the net effort is to conserve energy. In Illinois, all new homes have to adhere to the following requirements: Ice and Water Shield - Depending on how much overhang is on the roof, but typically 3-6 feet along perimeter, valleys and rises to prevent ice damming. Building Wrap - Like Tyvek which eliminates most infiltration. Insulation - minimum of R38 in attics and R19 in sidewalls. Fresh Air Intake - A fan tied into the return air duct on the furnace introduces fresh air into the home. The fan is controlled by a timer to run a few minutes per hour. 13 SEER A/C Unit and 80% Efficient Furnace - Minimum equipment requirements at this time. Envelope Test of Home - This is a blower door test to make sure the home meets the code requirement for infiltration. Duct Test - Any ductwork that is in an unconditioned area has to be tested with a duct blaster. This is a machine that checks for leakage in the ductwork. These items, along with other building requirements are all designed to save energy and improve indoor comfort.
