چکیده مقاله :
زمینه و هدف: بهینه سازی مصرف و جلوگیری از هدر رفت انرژی، یکی از پارامترهای مهم در طراحی ساختمان های سبز و غیرفعال در راستای اهداف توسعه پایدار به شمار می رود. تحقیقات اخیر توجه به مباحث مربوط به بهینه سازی انرژی و کاهش اتلاف حرارتی را نشان می دهد. هدف اصلی مقاله حاضر، ارزیابی عملکرد حرارتی دیوار سبز و بهینه سازی مصرف انرژی بوده که در اقلیم معتدل و مرطوب رشت انجام گرفته است.روش بررسی: این مقاله به صورت آزمایش تجربی و میدانی بر روی یک ساختمان مسکونی دو طبقه دارای پوشش سبز انجام شده است. در این راستا، داده های سه ساعته دما و رطوبت در محیط داخلی و خارجی ساختمان با استفاده از دستگاه دیتالاگر98583 MIC در فصل زمستان و تابستان ثبت گردید.یافته ها: نتایج حاصل از آزمون تجربی نشان داد که که میانگین دما در محیط داخلی دیوار معمولی و دیوار سبز در فصل زمستان و فصل تابستان به ترتیب حدود 3/17 و 18، 5/30 و 28 درجه سانتی گراد است. بر این اساس، دیوار سبز در فصل زمستان توانست حدود 7/0 درجه سانتی گراد دمای داخلی را در مقایسه با دیوار معمولی گرم تر نگه دارد. در فصل تابستان نیز مشخص شد که دیوار سبز قادر بود تا در حدود 5/2 درجه سانتی گراد دمای محیط داخلی را خنک تر نگه داردبحث و نتیجه گیری: یافته ها نشان داد که دیوار سبز در فصل زمستان در مقایسه با دیوار معمولی حدود 4 درصد و در فصل تابستان حدود 9 درصد عملکرد حرارتی بهتری را از خود نشان داده است. به طور کلی،دیوار سبز در آب و هوای معتدل هم در زمستان و هم در تابستان می تواند رفتار حرارتی مناسبی را داشته باشد. در نهایت نیز مشخص شد که دیوار سبز در فصل تابستان در مقایسه با فصل زمستان می تواند عملکردی 50 درصد موثرتری را در کاهش تلفات حرارتی داشته باشد.
چکیده انگلیسی:
Background and Objective: Reducing energy consumption by optimizing thermal losses is one of the most predominant parameters for designing sustainable and green buildings towards sustainable development goals. Recent research points to the importance of these issues to provide effective strategies. The main purpose of this study is to evaluate green wall thermal performance as an efficient strategy to reduce heat loss in cold and warm conditions in the humid climate of Rasht.Method: The present study was carried out through experimental measurement on a 2-story residential building of which it has a self-clinging plant attaching directly in the north direction. Through temperature and relative humidity data loggers, indoor and outdoor environmental data were collected.Findings: The results showed that the bare wall and green wall indoor average temperatures in winter and summer are about 17.3 and 18, 30.5 and 28 ° C, respectively. During wintertime, the green wall was able to keep the indoor temperature about 0.7 ° C warmer than a bare wall. In addition, in summer conditions, it was found that the green wall was able to drop the indoor temperature by about 2.5 ° C.Discussion and Conclusion: Based on the findings, the green wall could have 9% thermal performance in summer and 4% in winter conditions. Eventually, green walls have a suitable thermal performance to reduce heat losses in the humid climate of Rasht in both winter and summer. It was found that the green wall in summer in comparison with the winter season could be 50% more effective.
