This research is to create a coupled simulation of indoor environment, envelope, HVAC and control systems to support the controls design and evaluation of energy efficient ventilation. The fast fluid dynamics (FFD) model is adopted to model the indoor environment with stratified air distribution. The Modelica Buildings library is used to model the building envelope, HVAC and related control system. The models have been publically released as a part of the Modelica Buildings library since 2015.
