چکیده

مقدمه: در دهه‌های اخیر، ملاحظات محیطی و همچنین لزوم کاهش مصرف انرژی سبب شده است که استفاده از نور طبیعی در ساختمان‌ها به­ عنوان یکی از جنبه‌های اصلی طراحی مطرح شود. استفاده مناسب از نور روز در فضاهای آموزشی باعث افزایش بهره­وری انرژی و تأثیر مثبت بر عملکرد، تمرکز و کیفیت یادگیری دانش آموزان می ­شود. بنابراین، دستیابی به فضایی که هم دغدغه‌های آسایش بصری و هم صرفه‌جویی در مصرف انرژی را برآورده کند، نیاز به اتخاذ راهبردهای های طراحی یا اصلاحی دارد که نور روز را فراهم و کنترل نماید. از این رو هدف پژوهش حاضر، بررسی بهبود شرایط آسایش بصری مرتبط با نور روز و کارآیی انرژی در یک آتلیه معماری منتخب شهر اصفهان، با به ­کارگیری سیستم رف نوری در ترکیب با پنجره به عنوان راهبرد اصلاحی است.
روش تحقیق: فرایند انجام این پژوهش شامل: 1. شناسایی متغیرهای رف نوری و جداره نور گذر، 2. اجرای فرایند شبیه سازی روشنایی و انرژی، 3. تعیین میزان تأثیر متغیرها بر توابع هدف (دریافت نور مناسب و کاهش مصرف انرژی) با استفاده از آنالیز حساسیت، اجرای فرایند بهینه سازی و استخراج مدل ­های بهینه است.
نتایج و بحث: یافته­ ها نشان داد که طراحی بهینه رف نوری در ترکیب با پنجره، تأثیر قابل توجهی در بهبود آسایش بصری و کارآیی انرژی در فضای آموزشی در اقلیم شهر اصفهان داشت.
نتیجه ­گیری: با مقایسه نتایج شبیه­ سازی مدل پایه و برخی از پاسخ ­های بهینه، می­ توان مشاهده نمود که استفاده از رف نوری در این اقلیم و جبهه جنوب شرقی، منجر به بهبود شاخص نو روز (SUDI) به میزان 36.10، 37.50، 38.90، 37.50 درصد می­ شود. این در حالی است که این میزان ورود نور، نه تنها باعث افزایش میزان خیرگی آزاردهنده در فضای داخلی نمی‌شود، بلکه  خیرگی آزاردهنده را به میزان 72 و 75 درصد کاهش می ­دهد. همچنین استفاده از این سیستم، منجر به کاهش مصرف انرژی(EUI) به میزان 21.60، 25.00، 22.60، 23.50 درصد نیز می ­شود.

چکیده [English]

Daylight has significant effects on the visual comfort, well-being and productivity of users, and at the same time offers significant benefits for reducing energy consumption. On the other hand, the entry of too much daylight into the space increases the annoying glare and creates excessive heat of the building for the user. Therefore, considering the importance of the quantity and quality of natural lighting in the space, it is necessary to design and use daylight systems next to the openings. The present study evaluates the performance of daylight and energy in an architectural design studio located in Isfahan city, by using the light shelf system along with some variables of the glazing, a place where the importance of daylight to improve the visual comfort of the space from the users' point of view is twofold. The method of this research includes: identifying the variables of the light shelf and glazing, modeling (simulation modeling for daylight and energy), implementing the simulation process, determining the effect of the variables on the target functions (receiving appropriate daylight and reducing consumption) using sensitivity analysis, implementing the optimization process and extracting optimal models. Like the results of most researches in this field, the presence of a light shelf next to the window had a significant effect on improving visual comfort and energy efficiency. By comparing the simulation results of the basic model and some of the optimal responses, it can be seen that the use of light shelf in Isfahan city and the southeast front leads to an improvement in sUDI by 36.10, 37.50, 38.90, 37.50 percent and a reduction in energy consumption and reducing energy consumption (EUI) by 21.60, 25.0, 22.60, 23.50 percent. This is while this amount of light entering not only does not increase the amount of annoying glare in the interior, but also improves the glare by 75, 72.50 percent.
