ABSTRACT
The inner skin of the external windows and the atrium are equipped with motordriven sashes that are controlled by the central building management system (BMS), or by the occupants using wall-mounted switches. The windows can be closed by the BMS in unfavourable conditions, and air conditioning automatically activated. Lighting in the office areas is controlled automatically according to daylight penetration and occupancy. Night cooling can be instigated through the motorized opening of windows on summer nights.
