Comments on the following are due April 4, 2021.
- First Public Review of BSR/ASHRAE/IES Addendum z: This proposal would revise Section 9.1.4 requirements for interior and exterior luminaires so that track lighting equipment is subject to a lower minimum wattage (10 W/lin-ft compared to 30 W/lin-ft).
- First Public Review of BSR/ASHRAE/IES Addendum aa: The primary purpose of this addendum is to adjust the SI fan power values in Appendix G to the appropriate number of significant figures.
- First Public Review of BSR/ASHRAE/IES Addendum ac: This addendum provides a variety of updates to improve the lighting power and control requirements: 1) a new exception to the power and control requirements (Table 9.2.3.1) is proposed to support the use of germicidal ultraviolet lighting for room disinfection; 2) two existing exceptions are being removed and replaced with new power and control requirements (casino gaming areas and parking garage daylight transition lighting); and 3) one exception is being removed due to limited/unclear applicability (lighting for photographic processes.) Additional changes to improve language are also made throughout.
Comments on the following are due April 19, 2021.
- First Public Review of BSR/ASHRAE/IES Addendum ab: This addendum proposes changes to Section G3.1.1 to help clarify the process of selecting baseline HVAC systems for different building types using the Performance Rating Method (PRM.)
