Outside Air Flows

Occupied spaces need a minimum amount of outside air. We measure what each system is bringing in and confirm it meets the design rate.

What we do on site

• Measure outside air at the intake or outside air duct for each system.
• Set and verify minimum outside air damper positions.
• Compare the measured rate for each system with the design requirement.

When it’s needed

• Handover of new and refurbished systems.
• A change in occupancy or layout that puts more people in a space than the original design allowed for.
• When evidence of ventilation rates is needed for certification.
• Complaints of stuffy or stale air.

What you receive

A report showing design and measured outside air rates for each system tested.
