Low-carbon#1: Bristol Metropolitan Academy by Wilkinson Eyre Architects
Case study to show the six buildings with the lowest predicted annual CO2 emissions for their type
Services engineer Buro Happold
Annual predicted CO2 emissions 9.8kg/m2
Classrooms have cross-ventilation and air is evacuated through wind cowls on the roof. The client’s requirement for a 4 per cent daylight factor, rather than the typical 2 per cent, meant reduced demand for lighting. A biomass boiler supplies 80-90 per cent of heating and hot water. Buro Happold says reduced electrical use is more critical in schools than heating loads or envelope U-values.
