How it works in Carrickfergus
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. We keep work areas in Carrickfergus screened and tidy at the end of each day.
Balance
Air flows are measured and balanced to the design.
Local points to consider
Noise
Fans and grilles are selected and attenuated to keep noise down.
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.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
