Abstract
This chapter describes the architectural approaches to reduce energy usage. The David Maddison Clinical Sciences Building for the faculty of medicine in Newcastle, NSW, is located on a long-thin site with major facades facing east and west. The goals of flexibility in design and use, as well as the need for a high degree of repetition appropriate to fast construction, resulted in a structure where load-bearing columns are located outside the external wall. This has produced not only a powerful articulated facade but also has provided a support structure for external sun-shading. The need for rapid enclosure of the building dictated the use of a lightweight walling system. The architects' studies showed that the conflicting requirements of view, solar control, and day lighting were best satisfied by a horizontal louvre solar control system on the east and west facades. A series of manual technical studies were carried out and finally, the CSIRO temper program was used to simulate the thermal performance of the building.
