Simulation of the performance of HVAC systems and central plant for energy calculations: a component based modelling approach

In recent years, operational prediction and optimisation of heating, ventilating and air conditioning (HVAC) systems and central plant to minimise the energy required to maintain building indoor conditions have become increasingly important. To effectively design and implement an energy management p...
