How to: Structure a Building Performance Simulation

To implement a simulation setup for a building performance simulation we recommend to stick to the following schema.

Fig. 1: Abstracted Schema

• Pass medium (single or multiple) through into the models on top level.
• Don't be confused that hydronic network and ventilation system is outside the building model (of course in reality it would be installed inside the building)
• The Transfer model converts the fluid's thermodynamic changes into HeatPort information.
• Place all models that refer somehow to a control mechanism into the Controller area. For example does a thermostatic head belong into the Controller section, whilst the radiator valve belongs into the Transfer system.
