New Bristol academy exploits sustainable engineering principles
Thermal mass, biomass boilers and maximising daylight are among sustainable-engineering features of the new Bristol Brunel Academy.
Sustainability was a major consideration for the recently completed Bristol Brunel Academy, part of the Building Schools for the future initiative. It was designed by Wilkinson Eyre Architects, with Buro Happold as consulting engineer. The scheme by Skanska involved designing and constructing a state-of-the art academy to cater for 1200 pupils aged 11 to 18. It replaces the adjoining Speedwell Technology College, which is to be demolished. The academy comprises a 3-story split block of accommodation, subdivided into two teaching areas, arranged around a central atrium. A series of internal footbridges and perimeter walkways connect each area within the building. Among environmental measures are biomass boilers to provide most of the heating and hot water. There is also a rainwater harvesting system with a capacity of 100 000 l; a full tank provides enough rain water for seven days’ use of the toilet facilities. Thermal mass is provided by a concrete frame, enabling the school to operate as a predominantly naturally ventilated building. Daylight levels in excess of 4% have been achieved in teaching areas to reduce the dependence on artificial lighting.
