summary Sustainability is recognised as a necessary public good. Building sustainable buildings requires architectural methods, specifically CAD systems, that include suitable predictions of long term performance. Unfortunately the predominant view in the Building Industries of the Developed world is essentially short term; this is because building developers – not being the end users - are essentially interested in short term profit. Until they can see the ‘value-added’ by sustainability impacting on the selling price of their buildings, they will not be motivated to build ‘sustainably’. This paper describes the issues that have led to this situation. It discussed how the advent of computers has allowed life-cycle data to be gathered over time, and may be included intro CAD system databases to enable sustainability performance predictions to be made. Once made we are now able to reap the benefits by performance benchmarking. The availability of this building performance information on-line is making life-cycle costing more readily available, and more accurate, allowing building developers, owners and users to make rapid and timely feasibility studies well in advance of design. This also allows owners to test various capital to operating cost options in order to get the best economic performance over time, as well as map future capital replacement cycles. These emerging possibilities are discussed in this paper.
