Building simulations using thermal and CFD models

This paper describes two simulation software packages which permit building designers to understand how buildings will perform: the ESP building energy simulation system and the ARIA Computational Fluid Dynamics (CFD) air distribution simulation system. One of the major problems with CFD code is the specification of boundary conditions for the problem. ESP can provide the boundary conditions information for the CFD airflow, simulation. Two brief case studies are presented which illustrate the ability to provide the boundary conditions for the CFD problem from ESP.
