Intent
To support design features that increase the capacity for occupants to adapt to changing climate conditions and be protected from events that may compromise the quality of the indoor environment and subsequently occupant health and well-being.
Requirements
Comply with any of the following options for up to 2 points:
Option 1. Management Mode for Episodic Outdoor Ambient Conditions — New Construction Only (1 point)
This option applies to LEED BD+C: New Construction projects only.
Design systems with the capability to operate an episodic outdoor event management mode as described in ASHRAE Guideline 44. The mode should address varying outdoor conditions or events that could negatively influence IAQ, such as wildland fire smoke. Include the management mode in the design and commissioning documents. Verify proper implementation of the mode during commissioning.
AND/OR
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 TMY. 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 TMY. 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.
What does it cost?
Cost estimates for this credit
On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.
Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.
This information is also available in a full PDF download in The Cost of LEED v4 report.
