This paper describes current research into the performance ‘decay’ of built assets over time through the enumeration of physical condition, space utilization and triple bottom line reward. Applying a retrospective study of the Melbourne General Post Office (GPO) from 1841 to today, these three variables can be assessed and mapped in 3D space using Langston and Smith’s iconCUR model. An index comprising all three variables can be constructed to track the performance of this building over its life cycle to test whether traditional theoretical decay curves used in asset management have any practical value. Such an approach can be employed to model the performance of any building in real time and support decisions about future change and upgrade. The specific methodology to be used in this research project and the implications of results in making better decisions about built assets is explained.
