چکیده

فضاهای باز و معابر عرصه‌هایی هستند که زندگی جمعی در آن‌ها جریان دارد، بسیاری از فعالیت‌های مردم در فضاهای باز شهری انجام می‌شود، حال آن که تابش مستقیم آفتاب و دمای شدید هوا به خصوص در اقلیم گرم و خشک، سبب کاهش حضور مردم در فضاهای باز شهری می‌شود. از این رو توجه به آسایش حرارتی بیرونی در فضاهای شهری بیشتر می‌گردد. کنترل تابش و سایه‌اندازی از راه‌های موثر در بهبود آسایش حرارتی در فضای باز است. پژوهش حاضر به بررسی انواع سایه‌بان‌های غشایی انعطاف‌پذیر، به عنوان یکی از عوامل ایجاد آسایش حرارتی در فضاهای بیرونی می‌پردازد. این پژوهش از نظر روش‌شناسی توصیفی-تحلیلی با اهداف کاربردی است که داده‌های مورد نیاز آن به شیوه اسنادی، کتابخانه‌ای و بررسی نمونه‌های موردی جمع‌آوری شده‌است. در نتیجه سایه‌بان‌های غشایی انعطاف‌پذیر با خواص ظاهری و حرارتی خاص خود، کنترل دما و ایجاد سایه برای فضاهای بیرونی به خصوص در اقلیم‌های گرم مناسب بوده و شرایط آسایش را به خوبی فراهم می‌کنند. تطابق سقف‌های منعطف با اقلیم منطقه در تمام روزهای سال از ویژگی‌های آن‌ها است. به علاوه سایه‌بان‌های متحرک، به هنگام باز بودن، سبب ایجاد سایه در ساعات حضور خورشید می‌شوند، و در هنگام بسته بودن امکان بهره‌گیری از نورخورشید را در مواقع لزوم فراهم می‌کنند.

چکیده [English]

Open spaces and passages are areas where public life takes place, many people's activities take place in urban open spaces, while direct sunlight and intense air temperatures, especially in hot and dry climates, reduce the presence of people in open urban spaces. Therefore, more attention is paid to outdoor thermal comfort in urban spaces. Radiation control and shading are effective ways to improve outdoor thermal comfort. The present study investigates the types of flexible membrane canopies as one of the factors causing thermal comfort in outdoor spaces The methodology of this research is descriptive-analytical with practical purposes that the required data has been collected through documentary, library and case study. As a result, flexible membrane canopies with their special physical and thermal properties, temperature control and shading are suitable for outdoor spaces, especially in hot climates, and provide good comfort conditions. One of their features is the adaptation of flexible roofs to the climate of the region in all days of the year. In addition, when movable canopies, are open, provide shade during the hours of the sun, and when are closed, allow the use of sunlight.
