and fittings, controlled by a dimming system capable to adjust the lamps power to the actual local lighting needs, in combination with the natural light contribution. A presence control system will switch off lights in empty rooms. Thermal comfort conditions are provided by a primary air (distributed by means of a displacement ventilation system) plus radiant ceiling system. This combination minimises electricity consumption in pumps and fans. Lightweight radiant ceilings allow for lower air temperature in winter and higher in summer, thus reducing energy consumption; moreover, the presence sensors, coupled with C0 2 sensors, can modulate both the air flow and the ceiling temperature when few or no people are in the room, thus avoiding useless energy consumption. In summer night cooling takes place. Gas engines are the core of the energy system of the building. They are coupled to electric generators to produce most of the electricity required. The engines’ waste heat will be used for heating in winter, for cooling, by means of absorbtion chillers in summer, and for hot water production all year round. A sophisticated, “intelligent� control system manages the plant.

Because of the cleaner electricity produced, the amount of C02 emissions per square metre of the SIEEB is far lower than in present Chinese commercial building stocks.
