Abstract
Up to now, the performance-based concept has been very rarely extended from engineering phase to other phases within the building process. To achieve more sustainable and more intelligent constructions, the construction industry needs decision support systems that integrate a selection of processes, constraints, time span, and performance criteria that are relevant to all involved stakeholders. This paper intends to demonstrate a design methodology that solves these challenges, and provides several frameworks for decision support systems deemed relevant to the construction industry. Examples of current applications are provided, together with a discussion on future opportunities. The possible synergy with new technologies is emphasized.
