How we approach commercial ventilation in Cosham
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.
Design and build or install-only
We design it, or install to a consultant's drawings.
Heat recovery supply and extract
One or more units with ductwork to diffusers, sized for occupancy.
