Using Computer Analysis to Create Other ENERGY STAR Designs

As an alternative to the packages of energy features, manufacturers have the option of developing designs using computer software or procedures from the list of software available on the Residential Energy Services Network (RESNET) Exit ENERGY STAR Web site; designs generated through the use of these procedures and/or software must be approved by the plant’s Certifier.

The major advantage of the computer analysis option is the ability to tailor the design to a specific location and design considerations. For example, lower equipment efficiencies can be combined with a lower home Uo-value using this approach. The principal disadvantage of this alternative is the cost and time associated with conducting the analysis.
