S o l a r S c r e e n s

StudioMAS; Circa-on-Jellico

Use of decorative solar screens to shade external structure – facebrick & glass. Shading reduces direct heat load on the building which in turn reduces load on Air Conditioning system’s electricity consumption, particularly during peak load times.

This passive cooling, is an important retrofit on the poorly orientated Control Centre building.

Reducing and delaying temperature peaks

D e s i g n C o n c e r n s

Move away from long passage arrangement with cellular offices to either side Improve views across the width of the structure Radically improve quality of work environment Optimise solar control while increasing day lighting into spaces/passageway Create better integration between floors
