The building’s target for annual energy consumption was 100 kWh/m2
Extensive use is made of exposed thermal mass, including both the concrete soﬃts and exposed blade columns.
In Summer a two-sided ventilation strategy is used with air inlets on the east side of the building and vertical stacks on the west side, discharging at roof level. In Winter, a Breathing Buildings system provides natural ventilation airﬂow at close to room temperature.
Low energy LED lighting is provided throughout, with absence detection and daylight dimming. This is assisted by high levels of natural daylight.
