Vsledky simulac dobe odpovdaly namenm hodnotm. Introduction. Where, the results are used then to design building as required, so that to be able to meet the different requirements for energy consumption and indoor climate. The main principle of building energy simulation is to determine all the energy flows 1. Heat losses are through the building envelope (windows, walls ceiling and the floor), as well as through the ventilation system and infiltration. While thermal gains basically represent the solar heat gain through windows, internal heat from people, lighting and equipment. Therefore air conditioning system must take these facts into account in order to maintain an acceptable temperature indoor with reducing energy consumption to a minimum. It means that sub-models for walls, windows, and all other components inside the building must be modelled. This model, called HAMBase (Heat, Air and Moisture model for Building and Systems Evaluation) 2, and is one of the oldest simulation tools based on MATLAB environment in order to model the heat and humidity in the building. ![]() This model has continuously been improved and implemented in MATLAB. Important features for this work are: multi-zone modelling, solar and shadow calculations and multi climate conditions. Figure 1 shows a diagram of the building, where, the main dimensions in mm are clarified. One of them in north-northwest orientation, while the other in south-southeast orientation. Area of wood is 28.63 m 2, while area of concrete is 14.65 m 2. There is a window in each wall included inside steel frame. Area of glass is 9.64 m 2, while area of frame is 4.35 m 2. There is another external wall with orientation east-northeast. It is covered partially with a wood layer too, with the same layers. Area of wood is 36.65 m 2, while area of concrete is 33.40 m 2. Above roof, there is a room containing equipment for HVAC system. Its temperature changes between the indoor and outdoor temperatures, and it has been obtained by direct measurement. ![]() The modelling results have been compared with the results of a monitoring system installed inside to validate the modelling.
