Decision Support for Building Renovation Strategies

The renovation of existing buildings usually involves decision-making processes aiming at reducing energy consumption and building maintenance costs. The goal of this paper is to prioritize what components/systems need to be replaced. It focuses on renovation strategies from the maintenance density and energy consumption point of view. A Decision Support Framework (DSF) was developed for future development of Decision Support System. Data warehousing methodologies were used to extract, store and analyze maintenance data. A Web application was developed to display the frequency of faults and density of maintenance of six distinct buildings at University College Cork (UCC). A generic Decision Support Model (DSM) with six sections was developed, which was implemented to a computerized semi-automatic tool – Decision Support Tool (DST). Integrating the analysis results and the DST, five renovation suggestions were proposed.
