building, particularly where it made sense and
value could be demonstrated. Natural light is
optimised via clerestory glazing, roof lights and
internal courtyard windows, while artificial lighting
is zoned and activated by sensors. Environmental
performance modelling directly influenced the
articulation of the façade. The process informed
areas of fenestration, glazing specification, glare
control measures and solar shading.
Performance modelling also informed the
primary ordering of the internal layouts. For
example, a circulation zone was provided along
the external perimeter of the building to distance
resident desks from sources of radiant heat.
