Key Performance Indicators for Building Assessment. A case study on an R/C Building in Greece.

The acquisition of data regarding the performance of buildings and the use of metrics to understand their performance level are critical for efficient building management. Performance indicators are key elements in this process. They shall be clearly defined and provide the means for easily measuring building performance. These performance indicators should cover all aspects of a building's life cycle including safety, operability and sustainability. To facilitate such a process, it is preferable to group the performance indicators into categories, namely the key performance indicators. In this paper, the key performance indicators for buildings are determined by compiling the identified critical ones in the literature. A case study of an R/C building in Greece is used to quantify the presented metrics focusing mainly on safety. The reliability index indicator is calculated based on the simulation and analysis of a building subsystem. Other key performance indicators relevant to building maintenance are considered on scenario basis. The study has been conducted as part of the IABSE Task Group 5.2. – “Key Performance Indicators: Definition” and provides valuable insight into using quantified metrics for decision‐making in building management.
