Operational performance indicators and causality analysis for non-residential buildings

Abstract

During the operation and maintenance of a physical asset its performance may decrease. While an array of tools and methods have been developed to facilitate building performance assessment processes, their complexity and the lack of causality analysis make them impractical. The research presented in this paper aims to understand the most relevant performance areas for non-residential buildings in general, and determine key performance indicators (KPIs) and their relationship to assess the performance of non-residential buildings. The research approach comprised a literature review, a focus group, and a questionnaire survey. The findings revealed that the core indicators used to evaluate building performance are related to safety and assets working properly, health and comfort, space functionality and energy efficiency. External factors were also found to condition the building performance. Results also identified the relationships between the performance
