How we do it

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.

Demand control

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

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.
