A concept design is proposed for a new generation of superstores, which addresses the global problem of Carbon Dioxide emissions and the demand of retail traders for increasing economies in energy. The new superstore building has been engineered from the ground up to incorporate the current best practice in environmental design. With application of suitable energy conservation technologies it is proposed that this approach will provide a retail environment fit for the next millem1ium and achieve a 50% reduction in Carbon Dioxide emissions over a conventional supermarket.
