MVHR Commissioning & Compliance

Meeting Part F Building Regulations

ProAir ensures every installation meets the design standards in Technical Guidance Document (TGD) Part F. This gives you adequate ventilation while keeping energy use low and avoiding problems like noise and thermal discomfort.

How Commissioning Works

Commissioning means getting a system running and adjusting it to meet the design values. First, we check the volume of air supplied to or extracted from each room. We then compare the measured values against the design values.

If the measured rates match the design, the system is compliant. If any value falls short, we make adjustments and re‑measure all air flows. We repeat this process until every value meets the design – usually two or three times.

Accurate Measurements

We use a calibrated airflow device with a hood attachment to take measurements. Results are recorded in litres per second (l/s). When the ducting is correctly sized and the installation is done right, commissioning guarantees the system works as intended.
