RESNET Proposes Amendment to ANSI/RESNET/ICC Standard 301 on Building Size Adjustments to Energy Rating Index Score (BSR/RESNET/ICC 301-2014 Addendum E-201x, draft PDS-04, Index Adjustment Factors) – Deadline for Submitting Comments is October 26, 2017

Sep 26, 2017

RESNET will accept public comments on the proposed changes to preliminary draft addendum, PDS-03 of BSR/RESNET/ICC 301-2014 Addendum E-201x, Index Adjustment Factors, for 30 days beginning September 22, 2017 and ending October 22, 2017. Comments will only be accepted on the changes to draft PDS-03 indicated by the red text.

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.

The RESNET Standard Committee 300 has approved submitting the proposed amendment BSR/RESNET/ICC 301-2014 Addendum E-201x, draft PDS-04, Index Adjustment Factors to the RESNET standard amendment public review and comment process.

The proposed amended language is posted at BSR/RESNET/ICC 301-2014 Addendum E-201x, draft PDS-04, Index Adjustment Factors.

Only the proposed changes (denoted in underline-strikeout format) are open to comment.
