This Energy Consumption Guide is published as part of the Government's Energy Efficiency Best Practice programme (EEBPp), the building-related aspects of which are managed by BRECSU. The Guide incorporates a range of benchmarks against which the actual performance of sports. . Energy storage has become one of the hottest areas in power engineering as we transition to cleaner energy sources. With renewable energy growing rapidly worldwide, the need to bridge the gap between intermittent supply and constant demand has never been more critical. From understanding. . Sports facilities include swimming pools, dry sports halls, exercise rooms, internal and external courts, ice rinks, team game pitches and associated changing and social functions.
