Decision Support Tool for Energy Efficient Building Retrofit Actions

Abstract: This paper shows a process of developing a decision support tool to automatically generate building retrofit alternatives and rank them using energy performance analysis, user requirements, relevant benchmarks and regulations. Refinement of the retrofit scenarios follows a set of steps from creation of a Building Information Model of a base-case representing the status of the building at the time of the analysis, then creation of combinations for the possible retrofit scenarios. TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) based multi criteria approach is adopted as it relies on identified best alternatives using selected criteria. Ranking of alternatives follows their relative closeness to the identified ideal alternative. Best options are graphically presented.
