Commercial ventilation design and installation in Devon

Devon has every kind of building, from old terraces to new estates and business parks, and every job is designed around the building in front of us, not a standard kit.

What the work involves

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. We can work directly for occupiers and landlords, or as a subcontractor to fit-out and building contractors.

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.

Questions about commercial ventilation design and installation in Devon

Is the survey free in Devon?

For new installations on the UK mainland, yes. The survey is free and the quote that follows is fixed and in writing. Servicing, testing and repair visits are charged, and we confirm the cost before booking.

Do we need building regulations approval?

New or altered ventilation in non-domestic buildings usually forms part of the building control application for the works. We provide the design information and commissioning records needed.

Can the system cool as well?

Ventilation alone moves air; it does not cool much. Where cooling is needed we can coordinate with the air conditioning installer.

Which rules apply to ventilation in Devon?

In England, ventilation in new and altered homes is covered by Approved Document F of the Building Regulations. Landlords also have duties under the Housing Health and Safety Rating System, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
