04 — Ventilation
Ventilation
Systems specified for real occupancy and air-change requirements, then tested and balanced on site so they perform as designed — not just as drawn.
What this covers
Mechanical extract
Kitchen, washroom, process and general extract designed around the actual duty required.
Fresh-air handling
Supply air systems with heat recovery where it makes sense for the building's running costs.
Air quality compliance
Ventilation rates specified against occupancy and use, with the reasoning documented.
Testing and balancing
Commissioning with recorded airflow readings, so the installed system is proven rather than assumed.
Typical sectors
Commercial kitchens, offices, healthcare, education, laboratories and industrial process environments.
Worth knowing
Ventilation is frequently the discipline that gets value-engineered first and causes problems later — we'd rather flag that at survey stage than at handover.
