Requirements & Resources for HVAC Designers

For a home to be ENERGY STAR certified, several key design tasks must be completed by an HVAC designer. These requirements are contained in the HVAC Design Report, and include designing a whole-house ventilation system, calculating room-by-room heating and cooling loads, selecting heating and cooling equipment using those loads, and designing a duct system for the selected equipment. Visit the ENERGY STAR Certified Homes Program Requirements page to download the HVAC Design Report and visit the ENERGY STAR Certified Homes Policy Changes and Clarifications page to learn more about recent program changes. The resources below will help you complete these tasks.
