Commercial ventilation brings outdoor air into a building and removes stale air, using fans and ductwork to supply and extract air at the rates needed for the number of people and the activity.

From enquiry to handover in Cornwall
Assess
We work out how many people use each space and the fresh-air rate needed.
Design
Fan, duct and grille sizes are designed for air flow, noise and energy use.
Install
Ductwork and fans are installed and connected to controls. In Cornwall we agree timings around your opening hours.
Balance
Air flows are measured and balanced to the design.
Local points to consider
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
Conservation areas
Historic streets and listed buildings in and around Cornwall are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.

In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.

Yes, and they should. We coordinate grilles, controls and set points so both systems work efficiently.
