ملخص المقالة :
زمینه و هدف:شرایط اقلیمی فضای خارج از ساختمان بر عملکرد حرارتی فضای داخل ساختمان تاثیر گذار است، به این ترتیب می توان با ایجاد خرد اقلیم در مجاورت بنا، عملکرد حرارتی بنا را بهبود بخشید. یکی از راهکارهای ایجاد خرد اقلیم در اقلیم گرم و خشک، کاهش تابش مستقیم آفتاب در فصل گرم است. از این رو هدف پژوهش حاضر مطالعه دقیق عملکرد خرد اقلیمی حیاط مرکزی در اقلیم تهران می باشد. در پژوهش حاضر علاوه بر مقایسه دمای داخلی حیاط و دمای خارج، تاثیر آب و گیاه بر ایجاد خرد اقلیم مورد مطالعه قرار گرفت.روش تحقیق: روش تحقیق ترکیبی ازمطالعه نمونه های موردی، برداشت میدانی و شبیه سازی است.یافته ها: طبق اندازهگیریهای به دست آمده از چهار جهت حیاط مورد بررسی و مقایسه آن با دمای داخل کوچه و میانگین دمای ثبت شده در ایستگاه هواشناسی مهر آباد در همان ساعات برداشت، میانگین دمای حیاط 4.52 درجه سانتیگراد پایین تر از دمای کوچه و 4.01 درجه از دمای ایستگاه هواشناسی پایین تر است. نتایج حاصل از برداشت در فصل سرد نشان می دهد: دمای حیاط 0.9 درجه از دمای خارج از حیاط و 1.4 درجه از از میانگین دمای ایستگاه هواشناسی مهرآباد گرمتر بوده است. همچنین رطوبت نسبی داخل حِیاط به ویژه در مجاورت حوض آب و درختان بیشتر از فضای خارج از حیاط می باشد. به این ترتیب حیاط حوزه علمیه معمارباشی همچون یک خرد اقلیم عملکرده است. همچنین نتایج نشان داد: حیاط با پوشش گیاهی در فصل گرم، نسبت به حیاط با عنصر آب 0.9 درجه خنک تر بوده است.بحث و نتیجه گیری: با توجه به نتایج حاصل از شبیه سازی، عملکرد خرد اقلیمی حیاط مرکزی حوزه علمیه معمار باشی تایید شد. همچنین پوشش گیاهی، عملکرد خرد اقلیمی حیاط را بیشتر از عنصر آب بهبود بخشید.
