Are there addenda to 62.1 that address specific occupancies?

• A. No, there are no occupancy-specific addenda.
• B. Yes, but only for residential buildings.
• C. Yes, addenda provide occupancy-specific updates and clarifications (e.g., healthcare, schools).
• D. Yes, but only address commercial kitchens.

Answer: (C)

Occupancy-specific addenda to ASHRAE 62.1 exist to tailor ventilation and IAQ requirements to the needs of particular occupancies. These addenda provide updates and clarifications for settings such as healthcare facilities and schools, recognizing that patient rooms, waiting areas, classrooms, and other spaces have different exposure risks and operation patterns. For healthcare, the focus is on controlling airborne contaminants and isolation needs; for schools, the emphasis is on classroom ventilation rates, occupancy schedules, and common pollutant sources in educational environments. Because of this, the updates aren’t limited to residential buildings or to commercial kitchens; they cover a range of occupancies, including those mentioned and others. So the correct understanding is that there are occupancy-specific addenda with examples like healthcare and schools.
