| ارزیابی دیوار خارجی ساختمان به جهت دستیابی به ساخت و سازی پایدار در صنعت ساختمانسازی مسکونی ودر راستای کاهش مصرف انرژی وایجاد شرایط آسایش ساکنین دراقلیمهای مختلف همواره دارای اهمیت است. پژوهش حاضر تلاش داردتا رفتار حرارتی مصالح به کاررفته دردیوارهای خارجی ساختمانهای مسکونی واقع درشهر دزفول رامورد بررسی قراردهد. مدلهای آزمایشی مورد بررسی جمعا شامل دوازده نوع دیوار با مصالح: آجر سوراخدار، بلوک سفالی، بلوک هبلکس و بلوک لیکا به همراه عایقهای حرارتی ETICS و XPS هستند. در انتها به منظور شناسایی شرایط آسایش در درون فضاهای مسکونی با درنظر گرفتن مقیاس هفتگانه اشری بهینهترین دیوار معرفی میگردد. پژوهش فوق دارای روش شناسی کمی و مقایسهای است که بر پایه مطالعات کتابخانهای و میدانی با شبیهسازی 12 نوع دیوار در اقلیم گرم و نیمه خشک دزفول توسط نرمافزار دیزاین بیلدر به تجزیه و تحلیل پرداخته است. نتایج شبیهسازی در حالت ناپایدار مغایر با شرایط پایدار در اقلیم گرم و نیمه خشک است. براساس روش محاسباتی شرایطپایدار، دیوار با ضریب هدایت حرارتی کمتر دارای رفتار حرارتی بهینهتری است. در حالی که در شرایط ناپایدار، دیوار با جرم حرارتی بالاتر نقش موثرتری را به جهت دستیابی به شرایط آسایش حرارتی ساکنین ایفا میکند. از میان 12دیوار بررسی شده، با توجه به شرایط آسایش نشان داده شده در شاخص PMV و نظر به نیاز غالب سرمایش اقلیم گرم و نیمه خشک دزفول میتوان نتیجه گرفت که دیوارهای دارای عایقحرارتی ETICS و XPS دارای عملکرد مناسبی نیستند. در حالی که دیوارها با آجر سوراخدار، بلوک سفالی، بلوک هبلکس و بلوک لیکا بدون عایق حرارتی عملکرد بهتری را دارا هستند؛ از میان این دیوارها، دیوار با بلوک لیکا بدون عایق حرارتی مناسبترین رفتارحرارتی و دیوارها با بلوک هبلکس و آجر سوراخدار هر دو بدون عایق حرارتی به ترتیب در رتبه دوم و سوم در جهت دستیابی به آسایشحرارتی و کاهش مصرف انرژی قرار میگیرند. | ||

| چکیده [English] | ||
| To achieve sustainable construction in residential building industry and to reduce energy consumption and create comfort conditions for residents under various climates, it is required to examine the exterior shell of buildings serving as the main interface between the interior and exterior or spaces. This research thus aims to examine the thermal behavior of bearing or non-bearing walls used in the city of Dezful, which are made of perforated brick, clay block, Hebelex block (AAC) and Lica block, and to study the thermal insulations of ETICS and XPS in order to identify comfort conditions inside the space using the ASHRAE 7-point scale. The present research seeks to explore how the thermal behavior of materials incorporated into exterior walls influences heat transfer to interior spaces and the thermal confrontation of residential building dwellers in Dezful. The present research adopts a quantitative comparative approach and bases its analysis on secondary and field research, simulating 12 types of walls in the hot and semi- arid climate of Dexful using Design Builder software. Results suggested that simulation outputs in the dynamic mode did not resonate with sustainable conditions in the studied climate. The method adopted to calculate stable conditions indicated that the wall with the lowest thermal conductivity coefficient would behave the most optimal behavior. Contrastingly, the wall with the highest thermal capacity would be the most effective in achieving thermal comfort for dwellers under unstable conditions. Results of evaluations and analyses revealed that data on the thermal transfer of exterior walls varied under stable and unstable conditions, and calculations made under stable condition assumptions needed to be replaced by unstable conditions. The following results were obtained based on the comfort conditions of the 12 studied walls demonstrated in the PMV diagram and considering the dominant need for cooling in the studied climate: 1. XPS and ETICS heat-insulated walls did not perform well. 2. Walls made with clay blocks, perforated bricks, and Hebelex and Leca blocks without heat insulation performed better, among which Leca blocks with no heat insulation indicated the best thermal behavior in terms of energy consumption and thermal comfort. | ||
