I. Background

EERE through the National Renewable Energy Laboratory is developing voluntary work specifications for the work involved in home energy upgrades. This content builds upon the considerable body of material already in circulation and the cumulative knowledge gathered throughout the 30-year history of the Weatherization Assistance Program (WAP) and broader home performance industry.

The development of the SWS is supported by the WAP Training and Technical Assistance Plan (T&TA). The process of developing the SWS has involved participation by numerous stakeholders, including WAP practitioners and trainers, home performance contractors, building scientists, organized labor, healthy homes and worker safety experts, and other professionals in the building trades and throughout the retrofit industry. On November 9, 2010, EERE issued a notice requesting public Start Printed Page 18577comment on a draft version of the SWS (75 FR 68781). Additional background regarding this effort can be found in that document. The first public comment period resulted in nearly 1000 comments from approximately 100 unique commenters from across the Weatherization and home performance industries. As a result of issues identified by commenters, EERE gave further consideration to a number of technical issues and subsequently made changes to the SWS. EERE issued a notice requesting public comment on the changes to the SWS on March 29, 2012 (77 FR 19008). Due to the extent of the changes in the March 29, 2012 draft, additional time was requested by commenters for review and comment and the comment period for the March 29, 2012 draft was extended through a notice issued on April 18, 2012 (77 FR 23238). During this comment period DOE received submissions from 16 commenters, which DOE broke out into 367 comments.

II. Public Comments on the March 29, 2012 SWS Draft

DOE has reviewed all comments and incorporated those relevant and appropriate to the SWS. DOE received 4 comments from 4 individuals that were not applicable to the SWS and therefore has not provided any response to those comments.

Substantive, Reoccurring Comment Themes

Substantive issues raised in the 367 comments can be divided into the following four categories:

1. Combustion Safety—68.

2. Air Sealing—27.

3. International Residential Code—22.

4. Licensed Professionals—8.

1. Combustion Safety:

a. BPI-1100-T-2010: The SWS incorporated a reference to a draft version of the BPI-1100-T-2010 document for many of the Combustion Safety specifications. Comments made on by ACCA, AGA, and RSES identified that this reference was a draft and therefore should not be included within the SWS. These comments are available at under Docket ID: EERE-2012-WE-0042. The Building Performance Institute, Inc. (BPI) officially released this standard on July 27, 2012 (now BPI-1100-T-2012). After review and consideration of the standard, DOE determined that for the purposes of the SWS, the draft BPI standard referenced in the SWS is functionally identical to BPI-1100-T-2012. This standard provides the most relevant combustion safety protocols currently available for retro-fitting existing homes under the WAP. The SWS has been updated in order to reflect the change in status of BPI-1100 from a draft to a published standard.

b. ANSI/ACCA Standard 12 and NFGC: DOE received comments from ACCA and AGA indicating that the BPI procedure for combustion safety testing should not be specified and that either the National Fuel Gas Code (NFGC) or the ACCA 12 QH standard should be used instead. These comments are available at under Docket ID: EERE-2012-WE-0042. Many of the comments fail to consider issues faced when working in the existing homes sector: appliances are not necessarily installed to code; other actions may have taken place over the years; and other issues that can impact venting of appliances may have been done poorly (e.g. duct leakage). The non-mandatory combustion safety testing in Annex G of the NFGC does not evaluate two of the most common causes of excessive depressurization, namely duct leakage of forced-air distribution systems and the closing of interior doors. The ACCA 12 QH standard references the BPI procedure but also lists several other options. A review of these options indicates that only the BPI procedure is sufficiently comprehensive in its requirements. For example, the procedure in ACCA 12 QH Appendix A turns on the air handler at the same time as exhaust fans, potentially obscuring the depressurization caused by the exhaust fans.Start Printed Page 18578

The combustion safety procedure in the BPI-1100-2012 standard is the most applicable to the work performed by the WAP. This method was retained in the SWS. If a suitable replacement becomes ANSI-approved it may be appropriate to modify the reference.

2. Air Sealing

a. Reference Standards: DOE received comments from ACCA, RSES and AHRI requesting that references be cited for action levels, as well as the addition of industry standards along with current citations to the International Residential Code. These comments are available at under Docket ID: EERE-2012-WE-0042. In reviewing the comments, it was apparent that the content required additional referencing that was also easily searchable in order to improve the comprehensiveness and usability of the SWS. Therefore, a cross-reference document was developed to allow for users to identify referenced standards for individual specification lines that is included as an Appendix to the SWS titled “Appendix C: Guide to Referenced Standards”.

3. International Residential Code (IRC)

a. DOE received comments from ACCA and RSES, indicating the citation of specific sections of the 2012 IRC was not necessary. These comments are available at under Docket ID: EERE-2012-WE-0042. The comments identified that code sections are often revised and it would be better to cite “2012 IRC” versus a specific section. DOE acknowledges that code references are revised, however one of the goals of the SWS was to allow users to identify and find referenced information easily without having to purchase or search through numerous pages of referenced text. Due to the size of the IRC, it was apparent that referencing a specific section allowed the user to efficiently identify the section to refer to and be able to apply that knowledge quickly to the task. Therefore, citation of specific sections of the 2012 IRC remain in the SWS.

4. Licensed Professionals

a. DOE received comments from PHCC indicating that certain tasks should be carried out by individuals licensed in a particular trade. These comments are available at under Docket ID: EERE-2012-WE-0042. DOE agrees that the use of licensed professionals to perform certain tasks is an important component of maintaining work quality and safety. Given the wide range of licensure and credentialing requirements across the country, DOE made the decision to include a notification at the beginning of each detail in the SWS to alert the reader that the detail may contain a task requiring a licensed or credentialed contractor. This is intended to ensure that the reader is aware of the possibility of the need for a licensed or credentialed professional and to encourage them to verify this with the authority having jurisdiction.
