The main features of a new generation building simulation tool

A new generation building simulation tool combines the most important inter-acting physical processes (air infiltration and ventilation, heat transfer, and indoor air quality) in an reliable, effective, and flexible way. Here, reliability has been ensured by adopting solution routines based on the fundamental physical laws: mass balance, momentum, and heat balance equations. In addition, air flow and heat transfer calculation routines are tested by analytical and comparative test cases with other building simulation tools. An effective mathematical solution routine is adopted, and a modern object oriented programming environment is selected. These features offer new possibilities to develop fast and accurate building simulation tools for both general and special needs.
