ASHRAE Standards 62.1 and 62.2: Ventilation and Indoor Air Quality References
USEFUL SOURCES · OFFICIAL TECHNICAL RESOURCE · OCTOBER 2026
ASHRAE Standards 62.1 and 62.2 are major technical references for ventilation and acceptable indoor air quality in buildings.
What Is This Resource?
Standard 62.1 addresses ventilation and acceptable indoor air quality in non-residential buildings and certain related occupancies. Standard 62.2 focuses on ventilation and acceptable indoor air quality in residential buildings. Their provisions address ventilation systems and associated design or operational requirements, with the applicable edition and local adoption determining requirements.
What You Can Find There
- Ventilation approaches and minimum ventilation criteria appropriate to covered buildings.
- Technical requirements affecting controls, filtration, air cleaning and operation.
- Different residential and non-residential scopes.
- Edition-specific provisions relevant to engineering design and commissioning.
How to Use It in Practice
Begin by identifying the building type, occupancy and jurisdiction. Determine which standard and edition apply, then check the adopted local building code. An engineer can use the relevant ventilation calculation provisions and equipment design data; consumers can use public summaries to understand why outdoor air delivery matters.
Why It Matters for AirAlign
These references connect AirAlign’s CO₂ transmitters, air handling units, ventilation equipment and controls with actual building ventilation design. A CO₂ sensor provides information but cannot replace an engineered ventilation design.
