Heating is supplied from the district heating system. Both mechanical and natural ventilation are
used in the building. Mechanical ventilation is used in the most densely occupied areas, while
automatically controlled intermittent, or pulse, natural ventilation is used in the open plan office
areas. A building energy management system controls both the heating and ventilation systems
in each of the zones. On each floor, temperature is monitored in all 14 zones. Plan view of first floor showing layout of office space. on each floor and carbon dioxide concentration in four zones. The building is well insulated and air tight. On the western façade of the building the windows are protected from afternoon solar gain by the use of brise-soleils supporting solar PV cells. The windows and atrium roof provide a high degree
of day lighting which, together with smooth automatic light control, ensures minimal use of energy for lighting.
