The role of building energy modeling to ensure building sustainabilityand quality in a whole system design process

The problem of defining the best design solution relates on the one hand to the availability of different design options, on the other hand to the possibility to develop multi criteria analysis at any stage. To face this kind of analysis means to generate, quickly and without loss of information, refined models that can be implemented in different simulation tools. This paper analyzes the role of building information modeling as a consistent tool to generate this set of project alternatives that need to be compared to ensure building sustainability and quality in a whole system design process.
