What the work involves

Employers must make sure every enclosed workplace is ventilated by a sufficient quantity of fresh or purified air under the Workplace (Health, Safety and Welfare) Regulations 1992. 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.

Demand control

CO2 or occupancy sensors that slow the system when rooms are empty.
