thermal performance of smart canopy and natural ventilation in atriums in tehran

Atriums are central glass-roofed spaces that are usually considered closed and controlled spaces in multi-story buildings. this research aims to compare the effectiveness of adding an intelligent canopy and natural ventilation in the efficiency of atriums. for this purpose, an atrium has been selected in the educational space in tehran. in this regard, design builder software has been simulated and energy plus engine has been used for calculations. the results showed that the energy consumption in the building with the atrium in the form of a circular plan and a flat cap is equal to 207.1 (mwh). also, with the integration of the smart canopy in the atrium, the energy of the building was 201.33 (mwh), which decreased by 5.77 (mwh). this means that with the integration of the smart canopy in the atrium, the energy of the building has been reduced by about 3%. in the conditions of using natural ventilation, the energy of the building was 173.39 (mwh), compared to the integration of the canopy without natural ventilation, the energy of the building decreased to a significant amount of 27.94 (mwh), which seems to be a proper option considering the low cost of using natural ventilation.
