Lighting in Design Q4 2018

The role of lighting

according to its exposure, and one high up over- looking University Square, the primary open space for the campus. These were positioned and sized with project sustainability consultants, PJ Carew Consulting. Further to this, narrow skylights let in limited light through the roof into the upper level where perimeter light is lower. Key to deep light penetration is the 2,5 m gap between the concrete shell and the floor slabs.This allows natural light that would otherwise only ben- efit one level to benefit the level above and below. PJ Carew Consulting and Aurecon applied GBCSA principles with regards to daylight savings, including the use of occupancy sensors, photocells and timers. In addition to this, care was taken that no lighting illuminates the atmosphere to ensure there is no light pollution.

Accommodating social, library, study, research and administration functions, Designworkshop’s approach to lighting was threefold. First, to satisfy functional requirements for each of these activities in a zoned, cost-effective, durable, daylight respon- sive, and otherwise energy efficient way. Second, to use lighting to reveal the primary qualities of the building at night – for the five huge openings in the concrete walls to glow, themselves like city-scale light fittings – and for the totally transparent ground floor to be like daylight to welcome 24/7 study and illuminate the surrounding pedestrian routes. Third, to illuminate the form of the building as a sculptural object marking the university in the urban landscape. Natural light From the outside, the project is only a concrete shell with just the five openings to let light in. Natural light therefore became a primary influence on the project’s functionality, efficiency, experience and aesthetic. To allow the right amount of natural light deep into the footprints and mitigate heat-gain or loss, only one opening was positioned per orientation

Lighting requirements The ground floor 24/7 study space:

Part of the brief was for the ground floor to operate 24/7 after the library on the upper levels had closed for the night. It was therefore critical to provide
