The effectiveness of hot water collectors and photovoltaic cells on heating and reducing energy consumption in primary schools in Urmia (case example: girls' primary school in Urmia)

With the increasing environmental crisis, the use of solar energy became especially important, which can be an effective step to reduce pollution caused by fuels and energy consumption. Therefore, the use of new technologies in the architecture of educational spaces is considered essential. The use of photovoltaic system and hot water collector, which have a significant effect on heating, can be useful in this regard. The purpose of this research is to investigate the effectiveness of these two components on heating and reducing energy consumption in educational buildings in cold and mountainous climates. In the above research, in the first step, effective components were extracted by using library and document studies. In the second stage, first, the solar water heater has been dynamically simulated using TSOL software in Urmia region, then one of the existing schools in Urmia was investigated and analyzed, and by simulating the proposed educational building in Design Builder and Modeling Solar water heaters and photovoltaic cells on the building, their effectiveness and performance on heating, production energy and the percentage of hot water supply were investigated. According to the results obtained in the solar water heater, the amount of hot water supply will be 81.3%, the efficiency of this system will be 49.9% and the saved gas will be equal to 2670 cubic meters.The energy produced by the photovoltaic system in the power plant on the roof provides 47% and in the power plant on the south side walls 22.3% of the electricity consumption of the building throughout the year, and as a result of comparing the existing state with the proposed design, the total saving was 80.3%, so Hot water collectors and photovoltaic cells have a significant effect in minimizing the energy of educational buildings.
