Combining three main modeling methodologies for heat, air, moisture and pollution modeling

In the paper we consider three types of numerical simulation tools: Finite Element Method (FEM), Building Energy Simulation (BES) and State-Space (SS) together for Heat, Air, Moisture and Pollution (HAMP) modeling. We developed a simplified reference model regarding a residential building zone, for benchmarking the three mentioned modeling methodologies, i.e. BES, FEM, SS, including, Heat, Air, Moisture and Pollution (HAMP) physics. BES is based on lumped parameter modeling. By using FEM, the BES results can be extended to 3D high resolution images. Furthermore, by using SS, the computing time can be drastically reduced in order to make optimization of operation strategies possible. It is concluded that the main benefits of FEM-SS-BES modeling exchange is the possibility to simulate building energy performances with high spatial resolution and low computational duration times.
