With over 450 stores in the UK and a further 150 overseas, Marks and Spencer are one of this country’s retail giants. The company employs over 70,000 people worldwide and has recently moved into a new Head Office in Paddington, London.
The building is fronted by an impressive glass façade and boasts 1,500+ linear meters of HCP Trench Heating throughout the building. Hoare Lee & Partners, the consulting engineers, required a solution that could be quickly and efficiently be installed into the sealed pressurised floor void and chose HCP to provide a solution.
HCP designed and manufactured casings and heater elements that aligned with the client’s modular planning grid. This modular grid ensures maximum space flexibility, which is important when considering the building’s whole life costs. Changing requirements, in terms of adding or removing offices and/or meeting rooms, can be easily facilitated when the planning grid is mirrored by the services layout and zone control.
An advantage of installing Trench heating, as opposed to traditional wall mounted systems, is the increase in rentable floor space available to let. Other benefits include the combating of cold down draughts and condensation, problems which are often associated with full and half height glazing.
With the recent amendments to Part L of the Building Regulations, architects, engineers, consultants, contractors and clients are all looking for ways to reduce their carbon emissions. Because of the lower water volumes and pressures required to operated a natural convection trench heating system, they are considered more energy efficient than other heating systems, including traditional radiator systems and four pipe fan-coil units.
