How we approach commercial ventilation in Durham
In practice, designers work to rates such as 10 litres a second per person for offices, taken from Approved Document F and CIBSE guidance, and adjust for meeting rooms, kitchens and toilets. Typical jobs are fit-outs and refurbishments: a new tenant needs ventilation to match a new layout, an old system cannot keep up with more staff, or a change of use needs a fresh design.
Toilet and kitchenette extract
Dedicated extract for welfare areas.
Demand control
CO2 or occupancy sensors that slow the system when rooms are empty.
