چکیده

بیان مسئله: امروزه با توجه به مصرف بیش از اندازه‌ی انرژی بویژه در محیط‌های کاری و فضاهای آموزشی، در نظر گرفتن راهکارهایی به منظور کاهش مصرف انرژی در ساختمان‌ها امری اجتناب ناپذیر است. در راستای تامین مناسب نور روز و توجه به اثرات آن بر آسایش حرارتی داخلی، سلامت یادگیرندگان و همچنین کیفیت یادگیری در این پژوهش در نظر است تا طراحی مطلوبی از سایه‌بان‌های خارجی در ساختمان آموزشی مورد پژوهش به‌گونه‌ای در نظر گرفته شود که بتواند به بهره‌وری انرژی کارا و همچنین دریافت نور مطلوب روز دست یابد.

روش پژوهش: به منظور ارزیابی دقیق مباحث مرتبط با نور روز و مصارف انرژی، ساختمان مذکور در نرم افزار راینو مدلسازی شده و سپس با استفاده از نرم افزار گرس هاپر و افزونه‌های موجود در آن (Ladybug، Honeybee و Radiance) و به واسطه‌ی موتور ارزیابی Energy Plus، تحلیل‌های مختلف نور روز و انرژی بر روی آن انجام گردیده است. اهداف بهینه‌سازی مدل تحلیلی شامل کاهش مصرف انرژی الکتریکی متاثر از نور روز (Lighting)، حداکثر کردن UDI از طریق بهینه‌سازی فرم و هندسه سایبان و همچنین بهبود سایر شاخصه‌های نور روز است. به منظور سنجش دقیق‌تر، تحلیل‌ها در روزهای اول هر فصل از سال (انقلاب تابستانه/انقلاب زمستانه/ اعتدالین(بهار و پاییز)) انجام گردیده است.

نتیجه گیری: در بررسی‌های انجام گرفته مشخص شد که سایه‌بان‌های افقی با عمق 50 سانت بیشترین بازدهی را در شاخصه‌های کفایت نور روز(sDA)، روشنایی مفید نور روز(UDI) و درصد میزان خیرگی نور روز(DGP) به خود اختصاص داده اند. در حالیکه سایه‌بان‌های یکپارچه عملکرد بهتری در شاخصه‌ی ASE نسبت به دو مدل سایه‌بان دیگر کسب کرده‌اند.

چکیده [English]

Statement of the problem: Nowadays, due to excessive energy consumption, especially in work environments and educational spaces, it is inevitable to consider solutions to reduce energy consumption in buildings. In order to provide adequate daylight and pay attention to its effects on internal thermal comfort, learner health, and learning quality, this study intends to consider a desirable design of external shades in the educational building under study in a way that can achieve efficient energy efficiency and also receive optimal daylight.

Research Method: In order to accurately evaluate issues related to daylight and energy consumption, the aforementioned building was modeled in Rhino software and then, using Grasshopper software and its add-ons (Ladybug, Honeybee, and Radiance) and through the Energy Plus evaluation engine, various daylight and energy analyses were performed on it. The optimization goals of the analytical model include reducing the electrical energy consumption affected by daylight (Lighting), maximizing UDI by optimizing the form and geometry of the canopy, and improving other daylight indicators. In order to measure more accurately, the analyses were performed on the first days of each season of the year (summer solstice/winter solstice/equinoxes (spring and autumn)).

Conclusion: In the studies conducted, it was found that horizontal awnings with a depth of 50 cm had the highest efficiency in the indicators of daylight adequacy (sDA), useful daylight illumination (UDI), and percentage of daylight glare (DGP). While integrated awnings achieved better performance in the ASE indicator than the other two awning models.
