The steps for a project in Golders Green
Assess
We work out how many people use each space and the fresh-air rate needed.

Install
Ductwork and fans are installed and connected to controls. In Golders Green we agree timings around your opening hours.
Balance
Air flows are measured and balanced to the design.
Local points to consider
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.
Noise
Fans and grilles are selected and attenuated to keep noise down.
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.
