Ecologically sustainable development and architecture: the impact of rating tools

Abstract

The concept of Ecologically Sustainable Development (ESD) has become an important issue &ndash; albeit often scarcely applied &ndash; in the design of commercial buildings. To encourage the adoption of sustainable strategies in the practice of design and to address the environmental problems caused by these developments, governments and organisations of various countries have proposed the adoption of scorecard rating tools to inform designers of the impact of their decisions and to present a way of establishing project goals and objectives early in the design process. In Australia, the recent introduction of the Green Star Rating Tool (Office Design) is believed to provide the architects with a &lsquo;whole-of-building&rsquo; assessment of the environmental impact of their design by creating a checklist against which to benchmark performance. This paper follows the design of a commercial building, evaluating the impact of Green Star in the overall process. The results of the study suggest the need to include the use of scorecard rating tools in a more integrated model, where ESD is considered at every stage of design and construction rather than being a separate component applied only to promote the &lsquo;greenness&rsquo; of a building. Rating tools can be an asset to the design team, provided sustainable requirements are reinforced throughout the entire process.<br /
