Proposed RESNET Amendment

RESNET is Accepting Comments on Proposed Standard Amendment on HERS Index Size Adjustment Factors – BSR/RESNET/ICC 301-2014 Addendum E-201x, Draft PDS-03

Deadline for Submitting Comments is June 11, 2017
In the past there have been concerns expressed that it was more difficult for smaller sized homes to achieve lower HERS Index scores than it is for larger homes.
To address this issue the RESNET Standards Development Committee 300 authorized the release of a proposed standard amendment that incorporates a house size adjustment factor (BSR/RESNET/ICC 301-2014 Addendum E-201x, draft PDS-03).
The proposed Addendum E amends Standard ANSI/RESNET/ANSI 301-2014, Standard for the Calculation and Labeling of the Energy Performance of Low-rise Residential Buildings using an Energy Rating Index, to incorporate Index Adjustment Factors for dwelling size and configuration in Energy Rating Index calculations. Current Energy Rating Index calculations result in a disparity in the rating index for large versus small dwellings similarly equipped and configured for energy efficiency. Larger dwellings have lower energy rating index values than smaller dwellings. The purpose of the amendment is to establish an index adjustment factor methodology that adjusts the rating index for size and configuration in order that similarly configured and equipped dwellings of different sizes and configurations will achieve an equivalent energy rating index.
