ASHRAE 62.1 — Ventilation and indoor air quality
A standard addressing ventilation and related measures for acceptable indoor air quality in buildings within its scope.
Standards references reviewed September 15, 2026. These summaries explain purpose, not the full standard. Confirm the edition required by your contract, program, and jurisdiction; publication of a newer edition does not automatically change local requirements.
Why it matters
Applicability depends on the building, adopted requirements, and system. A design ventilation rate alone does not establish actual operating performance or rule out unusual contaminant sources.
In practice
A project example
A commissioning test compares measured outdoor-air operation with the project’s design requirements.
