What commercial ventilation design and installation 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.

Questions about commercial ventilation design and installation in Hampshire

Which rules apply to ventilation in Hampshire?

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.

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.

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