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:

This guide describes evaporative cooling technologies which can be used to cool homes in dry climates.

Guide describing combustion furnaces with compliance and installation guidance.

Guide providing information about geothermal (ground-source) heat pumps including an overview of technology and guidance on compliance and installation.

Guide describing gas-fired boilers and hot water heat distribution systems used for home heating.

Guide describing compression cooling air conditioning systems for space cooling.

Guide describing oil-fired boilers and hot water heat distribution systems used for home heating.
