This credit addresses a building’s ability to remain functional, maintain the quality of the indoor environment, and protect occupant health and wellbeing 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).

Leveraging information from IPp1: Climate Resilience Assessment and IPp2: Human Impact Assessment, select two strategies for up to two points. Teams can select any two options or paths, even those not identified as a high priority under IPp1: Climate Resilience Assessment .

Building readiness plans may be developed and communicated to facilitate operating in specialized modes only when necessary, and to educate building occupants on the transition from normal operations to management mode for the duration of the condition or event.

Option 1. Management Mode for Episodic Outdoor Ambient Conditions

Episodic outdoor ambient conditions can range from incidents such as the release of toxic chemicals outside a building to the widespread presence of wildfire smoke. Having an episodic outdoor event management mode facilitates the protection of building occupants from these and other outdoor pollution events.

System design for event management mode ASHRAE Guideline 44, Protecting Building Occupants from Smoke During Wildfire and Prescribed Burn Events, specifies enhanced modes of operation to preserve indoor air quality (IAQ) during periods of heightened outdoor air pollution.

Refer to ASHRAE Guideline 44 to design HVAC systems capable of operating in a smoke-ready mode or other event management mode. Teams can leverage guidance from Standard 44 to design and apply similar modes of operation for any events that impact outdoor air quality including increases in nearby construction activity or chemical gas releases.

Commissioning requirements ASHRAE Guideline 44 prescribes testing HVAC systems in smoke-ready conditions. Include the requisite sequences of operation in design documents and ensure that event management mode is included in the commissioning scope of work to verify that all equipment responds as intended.
