Section 3: Energy Efficiency

3.2

At this point you need to decide whether to use the prescriptive method or the performance method to score the house. If you opt to use the prescriptive method, you will be taken through a menu of energy efficient choices in the house envelope, HVAC and other energy consuming items for which points have been assigned.

If you opt to use the performance approach, you must use ResCheck to determine what percentage that the home's energy efficiency exceeds the requirements of IECC 2003 - 15, 30 or 40 percent. If you choose this method, you will not be allowed to choose from certain choices offered in the prescriptive approach, items related to the building envelope and the HVAC system that have already received credit in ResCheck. This scoring tool will not allow you to make those choices. If using the performance path, check which level of performance the home will achieve.

Choose Prescriptive or Performance path.
