HVAC Equipment Meets efficiency requirements
Exhibit 2 DOE Zero Energy Ready Home Target Home.
The U.S. Department of Energy’s Zero Energy Ready Home program allows builders to choose a prescriptive or performance path. The DOE Zero Energy Ready Home prescriptive path requires builders to meet or exceed the minimum HVAC efficiencies listed in Exhibit 2 of the National Program Requirements (Rev 07), as shown below. The DOE Zero Energy Ready Home performance path allows builders to select a custom combination of measures for each home that is equivalent in performance to the minimum HERS index of a modeled target home that meets the requirements of Exhibit 2 as well as the mandatory requirements of Zero Energy Ready Home Exhibit 1.
Installation guidance has been prepared for builders on some of the more common types of heating and cooling equipment available. This is not an exhaustive list and builders are welcome to select other heating and cooling options as long as their completed home meets the performance criteria or target home HERS index score required.
The following heating and cooling equipment guides are available:
