One of Quantum Group’s heating, ventilation and air conditioning installations has been a finalist for the H&V Awards retro-fit project of the year.

This installation at 99c Talbot Road, Notting Hill, London features a range of products with the full brief and project description below:

Halehold approached Quantum Group to replace the existing AC systems at this prestigious Notting Hill property which were unsightly, inefficient and running on obsolete R22 refrigerant. The brief was to replace the systems with new, efficient and more aesthetically pleasing systems.

The offices consist of two large open-plan office areas and a number of smaller office and meeting rooms over three floors. A large area of roof glazing resulted in a high solar gain and Quantum Group advised the installation of a window film to reduce peak cooling load.

To complement the industrial feel, exposed ducted systems were installed in each open-plan area, providing heating and cooling through circular diffusers. The result is clean but industrial thanks to the twin-wall insulated galvanised ductwork, negating the need for unnatractive foil-clad insulation.

Other equipment installed included three concealed ducted units; two Unico System fan-coils, two wall-mounted units and one ceiling cassette. Quantum Group also provided a new electronic fresh air ventilation louvre, over-door air curtain and replacement toilet extract system.

Custom built continuous linear grilles provide both supply and return air to the concealed ducted units, ensuring minimal visual obstruction where large, rectangular grilles may have been installed.

The two Unico systems provide almost silent high-velocity heating and cooling, achieving even temperature distribution and superior occupant comfort. Linear outlets were installed directly into sound attenuating Climaver® Neto ducts, to provide a discreet but effective solution.
