SunPipes are part of ASDA working towards lower energy use in new stores
Contributing to a 50% reduction in CO2 emissions from this new ASDA is the extensive use of Monodraught SunPipes
As part of ASDA’s comprehensive energy-efficiency programme, the recently opened store at Bootle, Merseyside, incorporates 35 Monodraught Sunpipe systems 450 mm in diameter to bring daylight into a wide area of the first-floor mezzanine. This area includes a customer restaurant overlooking the sales floor, staff facilities with restaurant and cafeteria, communal changing room, meeting room and offices. Other features of the store include a main structural frame built entirely from sustainably sourced Scandinavian timber, a roof of recycled aluminium and translucent walls. Monodraught also worked with M&E contractor SIAS on the specification and installation of 750 mm-diameter Diamond dome SunPipes, which are designed to give about 1000 lux at floor level and which can be used for buildings more than 7 m high. Mark Orpin, ASDA’s project manager for the store explains that the sustainability initiative began when Wal-Mart chief executive Lee Scott challenged ASDA to ensure that new model stores would be at least 30% more efficient and emit 30% less CO2 by 2009 compared to 2005 model stores. He says, ‘We therefore challenged our internal and external design teams to look for new techniques that would reduce energy. Thanks to sustainable initiatives such as SunPipes, the 3700 m2 Bootle town-centre store will be up to 40% more energy efficient and product up to 50% lower CO2 emissions than the 2005 baseline.’ He adds that the store is a commercially viable model that will save energy and reduce costs and that successful elements of this store, such as SunPipes, will be adopted for other model stores.
