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 are involved in the earlier stages of the design process. One decision to be made by stakeholders is what and how a renovation scenario can be developed that fulfills various types of competing criteria and sub-criteria attached to the sustainability in its whole sense such as investment cost, energy consumption, indoor thermal comfort etc. Building Information Modeling (BIM) has the potential to aid designers in providing the required geometrical and analytical data of an existing building 3D model to select and evaluate the proper type of renovation actions during the early design stage and to make decisions that have a significant impact on the life cycle of the renovated buildings.

This paper presents a methodology for the development of a BIM-based decision support system, named PARDIS (Process integrAting Renovation DecIsion Support), which generates and evaluates optimal and holistic renovation scenarios tailored towards dwellings. PARDIS 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 - KPIs (e.g. energy consumption, investment cost, indoor thermal comfort, indoor air-quality etc.) over the generated renovation scenarios, as well as (c) visualizing the generated renovation scenarios for ease of comprehension by the designers, and for enabling discussion between expert stakeholders (i.e. architects, engineers, contractors etc.) and non-expert stakeholders (i.e. building occupants, owners etc.). As such, PARDIS supports informed decision making in early design for the development of optimal renovation scenarios. The first prototype of the PARDIS Revit plug-in is demonstrated in this paper and empirically evaluated on a large apartment block in Denmark). Likewise, the tool’s outcome is explored through a focus group workshop with practitioners in Aarhus, Denmark. For further clarification of the potential use of PARDIS related to the studied case, the tool’s application is discussed with three BIM specialist-architect engineers (from different consultancy corporations).
