INTEGRATED SIMULATION OF HEAT DEMAND AND AIR EXCHANGE IN A MULTIFAMILY BUILDING

The paper presents the results of the measurements and integrated simulation of the energy demand and air exchange in one of the flats located in a 5-storey building located in urban area. The experiment was carried out during 3 weeks of March. The total energy consumption necessary for flat heating was measured continuously (at a 2 sec time step). After measurements were finished the energy demand and ventilating air flows were calculated assuming the same weather data variation as measured during the experiment, using the ESP-r software.
