ASHRAE 241-2023, Section B10.2 “Design Documentation.” Verify proper implementation of the mode during commissioning.
AND/OR
Option 3. Design for Occupant Thermal Safety During Power Outages (1–2 points)
PATH 1. CONSIDER EXTREME HEAT (1 POINT)
Demonstrate through thermal modeling that a building will passively maintain thermally habitable conditions during a power outage that lasts two days during peak summertime conditions of a typical meteorological year. Designate specific thermal safety zones where habitable conditions will be maintained during a power outage.
AND/OR
PATH 2. CONSIDER EXTREME COLD (1 POINT)
Demonstrate through thermal modeling or Passive House certification that a building will passively maintain thermally habitable conditions during a power outage that lasts two days during peak wintertime conditions of a typical meteorological year. Designate specific thermal safety zones where habitable conditions will be maintained during a power outage.
AND/OR
Option 4. Operable Windows (1–2 points)
Design 50% (for 1 point) or 75% (for 2 points) of the regularly occupied spaces to have operable windows with the capability to provide access to outdoor air during heat waves or localized power outages. The windows must meet the opening size and location requirements of ASHRAE 62.1-2022, Section 6.4.
REQUIREMENTS EXPLAINED
Incorporating resilient design solutions into our buildings increases the adaptive capacity of our communities, strengthening their capacity to respond to climate change and natural disasters.
This credit addresses a building’s ability to remain functional, maintain the quality of the indoor environment, and protect occupant health and well-being during major, episodic, disruptive events such as extreme weather conditions, wildfires, pandemics, or power outages. Although this credit addresses the design of events separately, teams are encouraged to consider and design for the possibility of multiple events occurring at the same time, such as a wildfire and extreme heat event.
