PARADIS - A process integrating tool for rapid generation and evaluation of holistic renovation scenarios

Research output: Contribution to journal/Conference contribution in journal/Contribution to newspaperJournal articleResearchpeer-review

Recent research in building renovation seeks methods for the development of more holistic renovation scenarios that live up to a broader set of sustainability objectives and criteria, and that involve more stakeholders in the earlier stages of the design process. This paper presents a methodology for development of a Building Information Modeling (BIM) based decision support system PARADIS, which generates and evaluates optimal and holistic renovation scenarios tailored toward the renovation of dwellings in a Danish context. PARADIS supports the renovation sector with the following features: (a) optimizing the selection process of renovation alternatives, and the generation of renovation scenarios, through specific renovation typologies and constraints; (b) evaluating standard sustainability Key Performance Indicators (e.g. energy consumption, investment cost, indoor thermal comfort, etc.) over the generated renovation scenarios; and (c) visualizing the generated renovation scenarios for ease of comprehension by the designers, and for enabling discussion between expert stakeholders (i.e. engineers, contractors, facilities managers) and non-expert stakeholders (e.g. building occupants, owners, etc.). PARADIS thus supports informed decision making for optimal renovation scenario design. The first complete integrated toolchain, including a ready-to-release prototype of the PARADIS Revit plug-in, is demonstrated in this paper and empirically evaluated on a large apartment block in Denmark.
