چکیده

بررسی‌های زیست‌محیطی و خرد اقلیمی انواع بام‌‌های سبز در مناطق خشک ایران، به‌منظور ارزیابی اثرگذاری احتمالی آن بر محیط پیرامون و شهروندان، پیش از توسعه و گسترش آن‌‌ها لازم به نظر می‌رسد. در همین زمینه پژوهشی در یکی از مناطق مسکونی شهر یزد با استفاده از داده‌های اقلیمی سال 1393 انجام شد. در این بررسی، شبیه‌سازی نرم‌افزاری منطقۀ مورد بررسی در زمان و مکان همسان، شامل بام سبز فشرده، بام سبز گسترده و بام بدون پوشش گیاهی با مدل ان‌وی‌مت صورت گرفت. خروجی‌های این مدل نشان داد که تأثیر دما، رطوبت نسبی و همچنین شاخص آسایش دمایی مورد بررسی در بام‌‌های سبز شبیه‌سازی‌شده در مقایسه با بام بدون پوشش گیاهی در بازۀ گرم سال، ناچیز و شایان‌توجه نبود. همچنین هر سه سایت شبیه‌سازی‌شده در محدودۀ تنش گرمای بسیار شدید قرار داشتند.

چکیده [English]

Environmental and microclimate studies of various green roof types in arid areas of Iran should be carefully studied in order to assess their potential effects on the surrounding environment and the citizens, before the development and expansion of them. By the same token, a research was performed in one of the residential areas of the Yazd city by using climate data of 2014. In this study, the software simulation on the research area at the same time and place was done, including: intensive green roof, extensive green roof and roof without vegetation with ENVI-met model. The outputs of this model indicated that the effects of temperature, relative humidity and thermal comfort index in the simulated green roofs have been negligible and inconsiderable in comparison with the roof without vegetation in the hot period of the year. Also the three simulated sites were in the extreme heat tension range.
