ABSTRACT
A double skin with a 600mm cavity encloses the fully glazed building. Automatically controlled inlet and outlet flaps are used to vary the thermal performance of the glazing. Corner fans provide lateral equalization of solar gain on the north and south faces. Workplace occupancy detectors activate the artificial lighting. Tracking solar collectors feed an absorption heat pump, which provides both heating and cooling. Additional cooling can be provided by the night ventilation strategy, activated by the ventilation flaps in the double skin, sliding inner windows and a retractable roof. The BMS is programmed with neural network knowledge-based software incorporating fuzzy logic, providing the system with the ability to ‘learn’ the energy status of the building. Users are provided with on-screen control panels for local environmental control.
