Energy targets for school projects within BSF are set within part L of the building regulations which require that buildings that are constructed to today’s standards are 40 per cent. more energy efficient (i.e. emit 40 per cent. less carbon through energy use) than those built five years ago.
Part L building regulations also require that renewable energy sources and other low carbon technologies are considered, and implemented where technically, practically and economically feasible. The regulations set an overall target for carbon emissions which implies that 10 per cent. of a building’s energy demand is met using renewable energy technologies—where renewable energy technologies are not adopted then the overall carbon reduction target must be met in other ways (e.g. through improved energy efficiency). Many planning authorities have also introduced a specific requirement for renewable energy which is typically set at 10 per cent. of predicted energy demand, and new schools must satisfy these local planning requirements.
