## ASHRAE 62.1 Ventilation
**Outdoor Air = (People x CFM/person) + (Area x CFM/sqft)**
ASHRAE 62.1 uses a two-part calculation: a per-person rate for bioeffluents and a per-area rate for building emissions. Office spaces typically use 5 CFM/person and 0.06 CFM/sqft.

计算示例
1,000 sq ft office with 10 occupants.
- People = 10 x 5 = 50 CFM
- Area = 1000 x 0.06 = 60 CFM
- Total = 50 + 60 = 110 CFM outdoor air
