These drafts are scheduled for a 30-day public review from June 29 to July 29:
1. BSR/ASHRAE/IES Addendum m to ANSI/ASHRAE/IES Standard 90.1- 2016, Energy Standard for Buildings Except LowRise Residential Buildings (Second Public Review)
The proposal has been revised to only allow a credit for buildings using the verification approach in order to help incentivize the more rigorous measurement and testing approach. To achieve this credit the Proposed Design air leakage has been set to 0.6 CFM/sq.ft, which is consistent with the value in Section 5.4.3.1.3(a)2.
2. BSR/ASHRAE/IES Addendum z to ANSI/ASHRAE/IES Standard 90.1-2016, Energy Standard for Buildings Except Low-Rise Residential Buildings (First Public Review)
The formulas in Section 11 and G3.1.2.1 for removing fan energy from baseline packaged heating and cooling efficiency ratings, removes more fan energy than allowed by Section 6 and Appendix G for large cooling equipment. This is corrected by capping the system capacity equations in Section 11 and providing a fixed baseline efficiency rating with the fan energy removed for each capacity range.
3. BSR/ASHRAE/IES Addendum ao to ANSI/ASHRAE/IES Standard 90.1-2016, Energy Standard for Buildings Except Low-Rise Residential Buildings (First Public Review)
This proposal revised fan product efficiency requirement and complements the fan power limitation in section 6.5.3.1.1.
4. BSR/ASHRAE/IES Addendum ap to ANSI/ASHRAE/IES Standard 90.1-2016, Energy Standard for Buildings Except Low-Rise Residential Buildings (First Public Review)
This proposal addresses HVAC systems with simultaneous heating and cooling require supply air temperature (SAT) reset except in climate zones 0A through 3A. In these climate zones, several system types can successfully dehumidify the outside air while still providing SAT reset and reducing reheat energy use.
5. BSR/ASHRAE/IES Addendum aq to ANSI/ASHRAE/IES Standard 90.1-2016, Energy Standard for Buildings Except Low-Rise Residential Buildings (First Public Review)
Lighting control requirements for lighting applications not covered in Table 9.6.2 require clarity and alignment to the mandatory lighting control provisions in section 9.4.1.
This addendum assures that each application listed plainly identifies which lighting control provisions apply to that specific lighting.
6. BSR/ASHRAE/IES Addendum ar to ANSI/ASHRAE/IES Standard 90.1-2016, Energy Standard for Buildings Except Low-Rise Residential Buildings (First Public Review)
During the development of the 2016 Standard, comments were received on Addendum di which were not incorporated at the time but were delayed until now so that the rest of Addendum di could be included in the 2016 version.
The changes below reflect some of those comments as well as changing the titles to a few of the new tables to make them consistent with other similar tables.
These drafts are scheduled for a 45-day public review from June 29 to Aug. 13:
1. BSR/ASHRAE/IES Addendum ai to ANSI/ASHRAE/IES Standard 90.1- 2016, Energy Standard for Buildings Except LowRise Residential Buildings (Second Public Review)
In this independent substantive change, several revisions have been made to addendum ai in response to comments. This ISC clarifies required verification and testing and the applicability of several defined terms.
2. BSR/ASHRAE/IES Addendum an to ANSI/ASHRAE/IES Standard 90.1-2016, Energy Standard for Buildings Except Low-Rise Residential Buildings (First Public Review)
In 2016, the U.S. Department of Energy published a final rule for energy conservations standards for commercial and industrial clean water pumps that will go into effect as of January 27, 2020.
This addendum provides a new table of information about the new efficiency requirements to users of ASHRAE 90.1. It also provides new definitions that are needed to accompany the table.
3. BSR/ASHRAE/IES Addendum as to ANSI/ASHRAE/IES Standard 90.1-2016, Energy Standard for Buildings Except Low-Rise Residential Buildings (FIrst Public Review)
The following appendix is proposed to be included in Standard 90.1 as informative resources to aid in the understanding and adoption of the commissioning and testing required in Sections 4.2.5, 5.9, 6.9, 7.9, 8.9, 9.9, 10.9, 11.2 (d), and G1.21(c).
