How we approach commercial ventilation in Barnet
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.
Heat recovery supply and extract
One or more units with ductwork to diffusers, sized for occupancy.
Toilet and kitchenette extract
Dedicated extract for welfare areas.
