چکیده

محیط داخلی راحت برای سلامتی، عملکرد و بازدهی تحصیلی دانش‌آموزان در مدارس ضروری می‌باشد. میزان بالای مصرف انرژی جهت تامین شرایط آسایش محیطی در ساختمان های آموزشی ایران، این ساختمانها را با مصرف انرژی بیش از 160 کیلووات ساعت بر مترمربع در زمره بزرگترین مصرف کنندگان بخش انرژی قرار داده است و نیاز به کاهش مصرف انرژی در این بخش از طریق راهکارهای همساز با محیط زیست ضروریست. هدف این تحقیق کاهش مصرف انرژی و تامین شرایط آسایش در ساختمان‌های آموزشی از طریق ایجاد تغییرات در لایه‌بندی عناصر پوسته ساختمان شامل دیوارها و جدارهای نور گذر به عنوان یک راهکار ترکیبی ایستا است. روش تحقیق در این مطالعه به‌صورت کمی و مدل‌سازی از طریق استفاده از نرم‌افزار دیزاین بیلدر می‌باشد و به بررسی وضع موجود و بهینه‌سازی انرژی ساختمان با متغیرهای؛ نوع عایق، ضخامت عایق حرارتی دیوار ها، لایه‌بندی عایق، نوع و ضخامت شیشه، گازهای مابین جدار، ضخامت جدارها پرداخته شد. نتایج نشان داد که در ساختمان موردمطالعه استفاده از عایق پلی‌اورتان در داخلی‌ترین لایه (پشت گچ نازک‌کاری) کلاس درس‌های جنوبی و شمالی باضخامت 10 سانتی‌متر بهینه‌ترین عملکرد را داشته است. همچنین در کلاس درس شمالی جدار نور گذر 2 جداره با شیشه کم گسیل با ضخامت شیشه 3 میلی‌متر و 13 میلی‌متر گاز آرگون با 28.40 درصد کاهش مصرف انرژی و همچنین در کلاس درس جنوبی با پنجره های با جدار نور گذر 3 جداره و شیشه معمولی 3 میلی‌متر و 13 میلی‌متر هوا 23.04 درصد کاهش مصرف انرژی مناسب‌ترین عملکرد را در بین سایر پیکربندی‌ها را داشته است.

چکیده [English]

A comfortable indoor environment is essential for the health, performance, and academic efficiency of students in schools. The amount of energy consumption to provide comfortable conditions in educational buildings in Iran has placed these buildings among the biggest consumers of the energy sector with energy consumption of more than 160-kilowatt hours per square meter, and it is necessary to reduce energy consumption in this sector through environmentally friendly solutions. This research aims to reduce energy consumption and provide comfortable conditions in educational buildings by making changes in the layering of building shell elements including walls and light-transmitting walls as a static combination solution. The research method is quantitative and modeled through the use of design-builder software, and to examine the existing situation and optimize the energy of the building with variables Insulation type, wall thermal insulation thickness, insulation layering, glass type, and thickness, gases between walls, wall thickness were discussed. The results showed that in the studied building, the use of polyurethane insulation in the innermost layer (behind the carpentry plaster) of the south and north classrooms with a thickness of 10 cm had the most optimal performance. In the north classroom, a 2-pane light-transmitting wall with low-emissivity glass with a glass thickness of 3 mm and 13 mm argon gas with 28.40% reduction in energy consumption, and also in the south classroom with windows with a 3-pane light-passing wall and 3 mm normal glass and 13 mm of air had the best performance of 23.04% reduction in energy consumption...
