ANSI/ASHRAE Standard 62.2-2025: Ventilation and Acceptable Indoor Air Quality in Residential Buildings

What the study found

Defines residential ventilation and source-control requirements, including updated filtration provisions.

Limitations

Minimum requirements do not directly specify cognitive or sleep outcomes.

Neurodesign interpretation

Residential air quality is a long-duration exposure problem. Bedrooms deserve special attention because occupancy is dense and continuous overnight.

Possible design implications

Use alongside bedroom sleep-air evidence and material-emission research.

Why it stays in the corpus

Retain for residential and hotel-adjacent IAQ baselines.
