The Energy Technologies Building is a £6.5m research centre which brings together world-class experts in energy research at The University of Nottingham. The 2500 m² facility provides the University with a centre that is specifically designed for continuing and developing its world-leading energy research. It should also attract increased attention from industry, academia, funding agencies, researchers and students and stimulate public interest in new developments in sustainable energy. It underlines Nottingham’s leading role in global energy research, and its commitment to developing low-carbon technologies with the potential to touch every aspect of 21st century life. The new building comprises specialist laboratories, a prototype hall, an exhibition area, a rooftop laboratory zone, offices and external technology area for use as an energy testing facility. It is an exemplar of low-carbon technology through the minimisation of its demands for heating, cooling, lighting and ventilation mediums from non-sustainable sources, whilst maximising energy from renewable and ambient sources. The sustainable design includes innovative earth duct passive cooling which uses the thermal mass of the surrounding earth to provide passive cooling and preheating of ventilation air. The development is targeting a BREEAM ‘Outstanding’ accreditation for sustainability.
