• A building-management system will be used to automatically control
heat, ventilation and air-conditioning (only when and where needed),
operate the automatic windows and vents, and monitor and record data
on systems and equipment. It will comply with existing control and fire
alarm systems.
• The atrium will be designed to draw fresh air through the refectory
space on the ground floor from outside the building, and emit used air
to the exterior via the windows and roof vents.
• Large floor-to-ceiling heights, as well as automatic (linked to the
building-management system) and manually operated high-and lowlevel
windows/vents on each floor; the roof will be designed to ensure
adequate cross-ventilation and maximise natural lighting.
• To further facilitate natural ventilation and free cooling through crossventilation,
the distance between the exterior walls and the internal
atrium will be below 10 metres.
• The penetration of north-light natural lighting into the building will
be maximised through the north facing roof-light glazing, the atrium,
translucent interior walls and windows with solar shading (when
needed). This will be supplemented with artificial lighting when
external conditions provide insufficient natural lighting. The design
aims to achieve power consumption of less than 12 watts/m2 with
all light fittings in use. Daylighting has been designed to achieve a
daylight factor of 4% in most areas except toilets, plant rooms and the
sub-basement computer rooms.
