N1103.6 (R403.6) Mechanical Ventilation (Mandatory)
JUMP TO FULL CODE CHAPTER
The building shall be provided with ventilation that complies with the requirements of Section M1505 or with other approved means of ventilation. Outdoor air intakes and exhausts shall have automatic or gravity dampers that close when the ventilation system is not operating.
Fans used to provide whole-house mechanical ventilation shall meet the efficacy requirements of Table N1103.6.1.
Exception:
Where an air handler that is integral to tested and listed HVAC equipment is used to provide whole-house mechanical ventilation, the air handler shall be powered by an electronically commutated motor.
FAN LOCATION | AIR FLOW RATE MINIMUM (CFM) | MINIMUM EFFICACY (CFM/WATT) | AIR FLOW RATE MAXIMUM (CFM) |
HRV or ERV | Any | 1.2 cfm/watt | Any |
Range hoods | Any | 2.8 cfm/watt | Any |
In-line fan | Any | 2.8 cfm/watt | Any |
Bathroom, utility room | 10 | 1.4 cfm/watt | < 90 |
Bathroom, utility room | 90 | 2.8 cfm/watt | Any |
For SI: 1 cubic foot per minute = 28.3 L/min.
- When tested in accordance with HVI Standard 916.
