How it works in Belfast
Survey the floor
We look at the ceiling void, the grid layout, window orientation, occupancy and where the outdoor plant can go. For sites in Belfast we confirm access and parking beforehand.
Zone the space
Open-plan, meeting rooms, reception and IT rooms are treated as separate zones with their own controls.
Coordinate the ceiling
Unit positions are set against the lighting and grid layout so cassettes and grilles sit neatly.
Install around the business
Work is phased by area or done out of hours so staff can keep working.
Commission and train
Controls are set with sensible limits and scheduling, and we show your facilities lead how to manage them.
Things to check in Belfast
Out-of-hours use
If staff work late or weekends, zoning lets you run only the areas in use.
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.
Fresh air
Air conditioning recirculates air; it does not provide fresh air on its own. Many offices need ventilation alongside it to meet the Building Regulations.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Typical premises in Belfast
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
Two rules matter for most businesses in Northern Ireland: EU F-gas rules that apply in Northern Ireland (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
