Public Review Drafts for Green Building Standard Are Available for Comment

ASHRAE has announced that the following public review drafts are available for review and comment online at osr.ashrae.org until July 26, 2020.

• 2^nd Public Review ISC of BSR/ASHRAE/ICC/USGBC/IES Addendum aq to ANSI/ASHRAE/ICC/USGBC/IES Standard 189.1-2017, Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings This independent substantive change to Addendum aq offers improvements to the code-intended language used in the Greenfield Site provisions. It also provides more specific wording about where on the project site the requirements are applicable.
• 2^nd Public Review ISC of BSR/ASHRAE/ICC/USGBC/IES Addendum ax to ANSI/ASHRAE/ICC/USGBC/IES Standard 189.1-2017, Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings The first public review of this addendum added a reference to Standard 62.1 Section 7, Construction and System Startup, which includes several requirements that support good indoor air quality. Subsequently, Section 10 requirements already covered via reference to 62.1 were deleted from the text. This second public review ISC reinstates one of the previously deleted requirements (the IAQ Construction Management Plan) with additional steps beyond what is stated in Standard 62.1.
• 2^nd Public Review ISC of BSR/ASHRAE/ICC/USGBC/IES Addendum bc to ANSI/ASHRAE/ICC/USGBC/IES Standard 189.1-2017, Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings This independent substantive change to Addendum bc modifies the original proposal to increase the threshold for building projects that must perform energy modeling for compliance with Section 7.5. Under this proposal, building projects greater than 25,000 square feet would be expected to perform a simulation per Standard 209, an increase from the original 10,000 square feet. A new exception has also been included to provide flexibility for modelers without the specified credentials.
• 1^st Public Review of BSR/ASHRAE/ICC/USGBC/IES Addendum bi to ANSI/ASHRAE/ICC/USGBC/IES Standard 189.1-2017, Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings This addendum revises the requirements in Section 6.3.2 for multiple showerhead installations designed to support water use reduction.
• 1^st Public Review of BSR/ASHRAE/ICC/USGBC/IES Addendum bj to ANSI/ASHRAE/ICC/USGBC/IES Standard 189.1-2017, Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings This addendum modifies the landscape design requirements in Section 6 to simplify and clarify that they are intended only for irrigated areas with the objective of reducing water consumption. This proposal also substitutes the term “adapted plants” with more enforceable language: “rainfall-ETc compatible plants and native plants.”
• 2^nd Public Review ISC of BSR/ASHRAE/ICC/USGBC/IES Addendum bo to ANSI/ASHRAE/ICC/USGBC/IES Standard 189.1-2017, Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings This independent substantive change to Addendum bo was created to provide clarification to the first public review draft in which new language had not been appropriately underlined.
• 1^st Public Review of BSR/ASHRAE/ICC/USGBC/IES Addendum bq to ANSI/ASHRAE/ICC/USGBC/IES Standard 189.1-2017, Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings This addendum adds an alternative compliance path for health care facilities that meet the requirements of ANSI/ASHRAE/ASHE Standard 189.3, Design, Construction, and Operation of Sustainable High-Performance Health Care Facilities. This comes in response to a CMP submitted by SSPC 189.3 with the goal of providing health care facilities the option of using 189.3 to comply with Standard 189.1/IgCC.
• 1^st Public Review of BSR/ASHRAE/ICC/USGBC/IES Addendum br to ANSI/ASHRAE/ICC/USGBC/IES Standard 189.1-2017, Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings This addendum removes the JO (jurisdictional option) designation from Section 8.3.1.3b, which requires ozone removal when outdoor air concentrations are expected to be elevated. Given the serious health impacts of elevated ozone concentrations and the ease of removing ozone from air, this requirement is more appropriate as a core requirement of the standard than as a jurisdictional option.
• 1^st Public Review of BSR/ASHRAE/ICC/USGBC/IES Addendum bv to ANSI/ASHRAE/ICC/USGBC/IES Standard 189.1-2017, Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings This addendum removes ANSI/BIFMA e3 from the list of standards for acceptable for compliance with Section 9.4.1.4.3. The ANSI/BIFMA e3 standard is a furniture sustainability standard and not directly applicable to the materials and resources referenced in Section 9 of Standard 189.1.
• 2^nd Public Review of BSR/ASHRAE/ICC/USGBC/IES Addendum w to ANSI/ASHRAE/ICC/USGBC/IES Standard 189.1-2017, Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings This addendum adds a jurisdictional option for new buildings with less than 100,000 ft² of conditioned floor area that are not high-rise to have air tightness verified using a whole building air leakage test. It also updates references to Standard 90.1 to reflect the 2019 version of that standard.
