چکیده مقاله :
امروزه طراحی سایبان خارجی نمای ساختمان به عنوان یکی از راهکارهای کاهش مصرف انرژی در ساختمان مورد توجه طراحان قرار گرفته است. با این وجود، طراحی هندسه و الگوی حرکتی سایبان همواره موضوعی چالش برانگیز برای طراحان محسوب می‌شود. باتوجه به اینکه همواره طبیعت و قوانین حاکم برآن منبع الهام انسان بوده است. بنابراین با انجام پژوهشی مختصر در این زمینه می‌توان دریافت که گیاهان مانند ساختمان‌ها توسط ریشه در جای خود ثابت هستند، اما برای محافظت از خود در برابر عوامل خارجی نیاز دارند که به تغییرات محیط خارجی واکنش نشان دهند. گاهی این واکنش‌ها به صورت رفتار حرکتی است و مطالعه و تحلیل الگوی رفتار حرکتی می‌تواند راهکار و ایده مناسبی برای طراحان به‌شمار آید. به همین دلیل، هدف از انجام پژوهش حاضر، طراحی سایبان هوشمند نمای ساختمان با الهام از الگوی رفتاری گل زعفران نسبت به تغییرات دمای محیط پیرامون جهت کنترل ورود نور خورشید به فضای داخلی ساختمان در اقلیم گرم و نیمه‌خشک شیراز است. روش پژوهش حاضر دارای ماهیت ترکیبی (کمی-کیفی) است و به صورت مدلسازی-شبیه‌سازی می‌باشد. از نرم‌افزار راینو6 و پلاگین گرس‌هاپر جهت مدلسازی سایبان و از افزونه‌ی لیدی‌باگ و هانی‌بی جهت تحلیل انرژی تابشی و آنالیز نور روز استفاده شده است. نتایج حاصله حاکی از آن است که حرکت سایبان هوشمند در اقلیم شیراز متناسب با مسیر حرکت خورشید می‌تواند 40 درصد انرژی تابشی جذب شده توسط سطح شفاف نمای جنوبی را کاهش دهد. علاوه‌برآن، پنل‌های سایبان در حالت باز می‌تواند نفوذ نور خورشید به فضای داخلی ساختمان را تا 50 درصد کاهش دهد. این نشان دهنده‌ی عملکرد مطلوب سایبان هوشمند نمای ساختمان متناسب با اقلیم شیراز است.
With the development of technology, energy consumption has increased globally, especially in the building sector. Therefore, this issue has become one of the main concerns of architects and designers for building design. One of the solutions provided so far to solve this problem is the use of kinetic shading devices for the facade of the building. Devices that follow the sun's path are an effective way to prevent buildings from overheating. They can also be used to regulate the thermal balance of a building. This feature can be used by the shade control system to save energy and reduce peak usage. However, it is challenging to create the best rule-based management systems that simultaneously minimize sun exposure, overheating, and energy consumption. Considering, that nature has always been a source of inspiration for humans, therefore, plants have been chosen as a source of inspiration for the design of kinetic shading devices. Plants, like buildings, are fixed in place by their roots, yet they react to the actions of their surroundings. Therefore, they have the same function as a building. Thus, we suggest a kinetic shading system in this research that uses Saffron movement. The experimental shading device guarantees the most effective performance with a variety of changes, according to a series of simulations by the Ladybug and Honeybee plugins in Rhino6 software. The results indicate that the movement of the shading device in the climate of Shiraz by the movement of the sun can reduce 40% of the sun's radiant energy absorbed by the transparent surface of the southern facade. In addition, the shading device panels in the closed state can reduce the penetration of sunlight into the inner space of the shading device by 50%. This shows the shading device's optimal performance according to Shiraz's climate.
