Integrated heat, air and moisture modeling in a single simulation environment

The modeling and simulation of whole building heat air and moisture (HAM) responses in relation to human comfort, energy and durability are relevant. Thc paper presents the integration of the following lumped parameter models: whole building, HVAC and primary systems and distributed parameter models: indoor airflow, HAM transport in constructions and external airflow/driving rain into a single simulation environment. It is concluded that the presented simulation environment is capable of modeling and efficiently solving a large range of complex integrated HAM problems related with different time scales and lumped/distributed parameters.
