Option 2. Management Mode for Respiratory Diseases — New Construction Only (1 point)
Design occupied spaces with the capability to operate an infection risk management mode that provides the minimum equivalent clean airflow rates outlined in ASHRAE 241-2023, Section 5.1. Include the management mode in the design and commissioning documents as outlined in 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.
