چکیده مقاله :

یکی از مهم‌ترین موارد در طراحی فضاهای شهری، تأمین آسایش حرارتی است.برای برقراری آسایش حرارتی توجه به عناصر و شاخص های اقلیمی نظیر تابش آفتاب،رطوبت هوا و باد نقش مهمی ایفا می کنند. شهر ایذه در بردارنده فضاهای باز متعددی در مقیاس محلی می باشد که به دلیل شرایط اقلیمی آن برقرای آسایش حرارتی در این فضاها به منظور افزایش حضور پذیری افراد و بالا بردن کیفیت زندگی بسیار مهم می باشد. از همین رو در این مطالعه ارزیابی شاخص های آسایش حرارتی مراکز محلات شهر ایذه و تبیین رهنمودهایی جهت دستیابی به آسایش حرارتی بر مد نظرقرار گرفته است. روش پژوهش مقاله پیش رو توصیفی و تحلیلی است. جهت جمع‌آوری اطلاعات از اسناد و منابع کتابخانه‌ای، مشاهدات میدانی و نیز به منظور تجزیه و تحلیل داده ها از تکنیک شبیه سازی و از نرم افزارهای تحلیل اقلیمی ENVI-Met استفاده شده است. از بین شاخص های آسایش حرارتی موجود برای ارزیابی آسایش حرارتی در این پژوهش شاخص های THI ، بیکر، ترجونگ و شاخص های SET, PET ، PMV و PPD جهت تحلیل شرایط آب و هوایی فضای باز در نرم افزار مورد استفاده قرار گرفته است. نتایج این پژوهش حاکی از آن است که در هر دو الگوی شعاعی و خطی، شاخص‌های فرمی تأثیر بیشتری بر کاهش دمای تابشی و تعدیل وضعیت اقلیمی بافت شهری دارند. همچنین پوشش گیاهی و فرمی در شاخص‌های آسایش حرارتی در الگو‌های شعاعی و خطی نشان می‌دهد که فرم و پوشش گیاهی هردو بر تعدیل شرایط اقلیمی و آسایش حرارتی تأثیرگذار می‌باشند برای ایذه.

چکیده انگلیسی:

One of the most important things in designing urban spaces is to provide thermal comfort. To maintain thermal comfort, pay attention to climatic elements and indicators such as sunlight, air humidity and Winds play an important role. Izeh city includes several open spaces on a local scale, which due to its climatic conditions, it is very important to establish thermal comfort in these spaces in order to increase the presence of people and improve the quality of life. Therefore, in this study, the evaluation of thermal comfort indices of Izeh neighborhood centers and the explanation of guidelines for achieving thermal comfort have been considered. Research Methods The present article is survey, descriptive and analytical. To collect information from library documents and resources, field observations and also to analyze the data and information obtained from the simulation technique and climate analysis software ENVI-Met has been used. Among the available thermal comfort indices to assess thermal comfort in this study, THI, Baker, Tarjong indices and SET, PET, PMV and PPD indices have been used to analyze outdoor weather conditions in the software. The results of this study indicate that among the two alternatives offered, the center of the neighborhood with a linear pattern has a lower level of thermal comfort than the radial pattern. Also, vegetation and form in thermal comfort indices in radial and linear patterns show that both form and vegetation are effective in modifying climatic conditions and thermal comfort for Ize.linear patterns show that both form and vegetation are effective in modifying climatic conditions and thermal comfort for Ize.
