An accurate building energy technology portfolio evaluation approach is needed that integrates physics-based models and business case analysis. Open source, parametric building modeling tools have recently matured to enable system-level building energy analysis at high fidelities. It is observed that these modeling tools usually only analyze energy savings and are not concerned with other criteria often factored into the choice of an energy technology portfolio. This paper presents an approach to constructing a parametric, physics-based, building-specific, business case analysis tool for quantifying multi-criteria performance of building energy technology portfolios. The resulting environment, which is used to build up a portfolio step-by-step and analyze performance trades, is explained through a case study. The application presented is for a building energy retrofit, comparing building energy consumption before and after application of technologies from a set of contenders, but it can be extended to the design of new buildings.
