چکیده

هدف از این پژوهش، برآورد انرژی نهفته اولیه و کربن دی‌اکسید معادل (CO2eq) برای جداره‌های متداول خارجی مسکن شهری سنندج واقع در ایران است. انرژی نهفته در سه منطقه شهری سنندج به‌ منظور تعیین اختلاف احتمالی بین مناطق موجود، بررسی‌شده است. در راستای شناسایی انواع جداره های خارجی ساختمان‌های مسکونی، از روش دلفی و نظرسنجی از افراد متخصص استفاده شد. بر اساس نتایج نظرسنجی ها، انواع جداره‌های خارجی در 10 نوع اصلی و 36 زیرمجموعه طبقه‌بندی شدند. محاسبات انرژی نهفته نشان می‌دهد که پایین‌ترین میزان انرژی اولیه متعلق به جداره نوع 5 (بلوک سفالی سوراخ‌دار 15 سانتی‌متری) و بالاترین میزان انرژی اولیه متعلق به جداره نوع 2 (آجر فشاری 20 سانتی‌متری) به ترتیب برابر 441.5 MJ و 1066.5 MJ است. همچنین پایین‌ترین سطح CO2eq متعلق به جداره نوع 10 (بلوک هبلکس 15 سانتی‌متری AAC) و بالا‌ترین سطح CO2eq متعلق به جداره نوع 2 به ترتیب برابر 7.773 kg CO2/kg و 24.761 kg CO2/kg است. منطقه 1 شهری دارای بیشترین و منطقه 3 شهری دارای کمترین مصرف انرژی نهفته برای هر مترمربع جداره های خارجی است. همچنین منطقه 1 شهری دارای بالاترین و منطقه 3 شهری دارای پایین‌ترین مقدار CO2eq برای هر مترمربع جداره های خارجی است.

چکیده [English]

The purpose of this research is to estimate the primary latent energy and carbon dioxide equivalent (CO2eq) for the common external windows of Sanandaj urban housing located in Iran. The latent energy in three urban areas of Sanandaj has been investigated in order to determine the possible difference between the existing areas. In order to identify the types of external walls of residential buildings, the Delphi method and a survey of experts were used. Based on the results of surveys, the types of external walls were classified into 10 main types and 36 subcategories. Latent energy calculations show that the lowest amount of primary energy belonging to wall type 5 (15 cm perforated clay block) and the highest amount of primary energy belonging to wall type 2 (20 cm pressed brick) are 441.5 MJ and 1066.5 MJ, respectively. Also, the lowest level of CO2eq belonging to the type 10 wall (15 cm AAC heplex block) and the highest level of CO2eq belonging to the type 2 wall are equal to 7.773 kg CO2/kg and 24.761 kg CO2/kg, respectively. Urban area 1 has the highest and urban area 3 has the lowest latent energy consumption for each square meter of external walls. Also, urban area 1 has the highest and urban area 3 has the lowest amount of CO2eq for each square meter of external walls.
