Organised by the Chartered Institution of Building Services Engineers (CIBSE), the annual award focuses on actual, measured performance outcomes, and not just design intent or performance specifications. Ravelin Sports Centre sets a new benchmark for ultra-low energy sports facilities in the UK. Judges were impressed with its careful, low-carbon design and application of technology to achieve a low-impact leisure centre with sports and swimming facilities. Paul Tilley, University of Portsmouth’s Director of Sport and Recreation, said: “It's another brilliant achievement for Ravelin Sports Centre and the University that this project has been recognised for its ultra-low energy performance and ongoing operation excellence. This solidifies our original aspirations of building a facility of the highest levels of sustainability and user experience.” One of the UK’s most sustainable sports facilities, Ravelin’s features include creating renewable energy from roof solar panels and internal heat recovery systems, grey water recycling methods by reusing wastewater from showers, hand basins and pools for flushing toilets, waste water drainage by creating an urban orchard, and having a biodiverse grassed roof. It has been graded A, the most efficient rating for energy use in buildings.
