چکیده
افزایش روزافزون جمعیت شهرها در کشور باعث بالارفتن میزان ساخت‌وساز و فعالیت‌های ساختمانی شده است˓ صنعت ساخت‌وساز از منابع طبیعی متعددی استفاده می‌کند و باعث انتشار مقدار زیادی گازهای گلخانه‌ای است. ازاین‌رو تأثیر به سزایی بر میزان انتشار دی‌اکسیدکربن در ایران دارد. در این مقاله باهدف بررسى تأثیر به‌کارگیری لایه عایق حرارتی در دیوارهای خارجی ساختمان‌ با استفاده از نرم‌افزار دیزاین‌بیلدر، یک ساختمان مسکونی در شهر تهران مطالعه شده است. در ابتدا یک ساختمان مسکونی 5 طبقه در نرم‌افزار دیزاین بیلدر مدل شده و با ثابت نگه‌داشتن تمامی مشخصات برای المان‌های مختلف˓ برای دیوارهای خارجی˓ تعداد 10 سناریو متفاوت با استفاده از 9 نوع عایق حرارتی متفاوت و یک حالت نیز بدون عایق تعریف گردید. سپس خروجی‌های موردنیاز از نرم‌افزار شامل میزان کربن نهفته˓ کربن نهفته معادل و همچنین میزان انتشار کربن در دوران بهره‌برداری ساختمان ناشی از هر سناریو مورد تجزیه‌وتحلیل قرار گرفتند. نتایج نشان داد کمترین میزان کربن نهفته مربوط به حالتی است که از لایه عایق پشم‌شیشه استفاده می‌شود و کمترین میزان انتشار کربن در طی دوران بهره‌برداری مربوط به حالت استفاده از فوم پلی‌اورتان است. لایه عایق بهینه از لحاظ مجموع انتشار در دوران بهره‌برداری و کربن نهفته نیز فوم پلی‌اورتان است که بعد از گذشت یک دوره ۳۰ساله از بهره‌برداری ساختمان در مجموع بالغ بر 1178 تن کربن در محیط‌زیست منتشر می‌کند.

چکیده English

The increasing population of cities in the country has caused an increase in the amount of construction and construction activities. The construction industry uses many natural resources and produces a large amount of greenhouse gases. Therefore, it has a significant effect on Iran's carbon dioxide emissions. In this article, a residential building in Tehran has been studied with the aim of investigating the effect of applying a thermal insulation layer to the external walls of the building using Design Builder software. Initially, a 5-story residential building was modeled in Design Builder software, considering all specifications for different elements of the external walls. Ten different scenarios were defined, including nine different types of thermal insulation and one case without insulation. The necessary outputs from the software, such as hidden carbon content and equivalent hidden carbon, as well as the carbon emissions during the building’s operational phase for each scenario, were analyzed. The results showed that the lowest embodied carbon content was associated with the use of glass wool insulation, while the lowest carbon emissions during the operational phase were related to the use of polyurethane foam. In terms of total lifecycle emissions and embodied carbon, the optimal insulation layer is polyurethane foam, which releases a total of 1178 tons of carbon into the environment over a 30-year building lifespan.
