Abstract
Introduction: With increasing global concerns about climate change and the need to reduce energy consumption in line with sustainable development, optimizing energy consumption in educational buildings has gained special importance due to their key role in consumption patterns and direct impact on user comfort and productivity. This study aimed to evaluate energy performance and provide optimization solutions in four newly built schools in Babol city, including Noshirvani, Shokoh, Barakat Foundation, and Shahrabi, in a temperate and humid climate.
Research Methodology: This applied study was conducted based on field observations, detailed simulation in DesignBuilder software based on the EnergyPlus engine, and climate analysis with Climate Consultant. The schools studied were less than 5 years old, and solutions such as thermal insulation of the roof and walls with polystyrene, adjusting the comfort temperature of cooling and heating systems, utilizing natural ventilation, replacing conventional windows with low-emission glass, and installing 30 kW solar panels were evaluated.
Results and Discussion: The results showed that the total energy consumption index of schools varied between 58.8 and 66 kWh/m2/year. Insulation reduced energy consumption by 11 to 20.7%, and comfort temperature regulation alone resulted in savings of 16 to 19%. Natural ventilation also reduced the cooling load by 4.4 to 10% and total energy consumption by 2.2 to 5%. Simultaneous implementation of the solutions resulted in a 22 to 24% reduction in energy consumption. Economic analysis also showed that the solar system is very financially justified.
