LJJ Building Services Contractors has been chosen for the £8.5 million building services installation contract at the Royal Holloway student accommodation scheme in Surrey.

The work is part of the Willmott Partnership Homes’ £39 million scheme for Royal Holloway, University of London, and will be delivered as part of the Scape Major Works Framework.

Stride Treglown of Bristol have designed the scheme which will form the cornerstone of the university’s North Campus in Egham, Surrey.

Across the 56 townhouses there will be 621 student bedrooms, along with an amenity block featuring several teaching spaces and a lecture theatre. This will allow the university to offer all first year undergraduates with a residential place.

As part of the BREEAM Excellent scheme, LJJ will install a new district heating system in the new amenity block which will be linked to the whole university building management system.

The primary energy source will be a combined heat and power unit which will deliver 90kW of thermal energy and 49kW of electrical energy.

Also featured in the system will be three gas fired boilers with a total output of 1,250kW for boost and back up, while LJJ will also install a pre-insulated direct heating main that will run beneath the development to deliver domestic heat and hot water to the townhouses through a 300 litre heating interface unit in every building.

In terms of cold water supply, LJJ will install a cold water storage tank of 30,000 litre capacity along with a booster system.

The company will also install a mechanical ventilation system with heat recovery in the roof space of all town houses to feed the supply and extract for all communal areas, kitchens, corridors and bathrooms.

The electrical installation will involve provision of a new HV network, including a new transformer and three HV ring main units.
