Ventilation measurement
We measure and balance ventilation airflows to ensure a compliant indoor climate.
Ventilation measurement is a procedure where we measure the supply and exhaust airflow at every valve and check that it matches the design and EVS 837-1 standard.
Airflow balancing ensures every room gets enough fresh air while the system doesn't waste electricity. In a poorly balanced system, some rooms feel draughty and others oxygen-deprived.
Measurement is needed when commissioning a new installation, preparing an energy certificate or optimising an existing system.
What does the service include?
- Diffuser measurement
- Supply and exhaust airflow check

Our process
- 1
Scheduling
We agree a time; usually takes 2–4 hours.
- 2
Pre-check
We check filters, the unit and valves.
- 3
Measurements
We measure all diffusers with calibrated equipment.
- 4
Balancing
We adjust diffusers and the unit so airflows match the design.
- 5
Report
We issue the measurement report with recommendations.
Pricing
Factors affecting price
- •Number of measurement points
- •Building size and floor count
- •Whether balancing is needed too
- •Whether noise or CO₂ measurement is needed
Indicative prices
Measurement often pairs well with annual maintenance — bundled price available.
