Thermal modelling of the building and its HVAC system using Matlab/Simulink

The aim of this paper is to develop a simplified building-HVAC system which could predict the temperature variation within the building and estimate the amount of energy required to get the comfort level using the Matlab/Simulink. For the estimation, this model would take into account of different physical properties of building, location of building, weather, gains and heating system. As a case study, the model has been implemented to a semi-detached dwelling with all the real data. The results obtained from Matlab/Simulink are then compared with another software which is verified against IEA Building Energy Simulation Test (IEA BESTEST) building load and HVAC tests. The main advantage of this model is its simplicity and less computational resources.
