چکیده مقاله :
زمینه و هدف: حدود 44 درصد مصرف انرژی در بخش ساختمان است به همین دلیل توجه به شاخص های آسایش حرارتی و راهکارهای غیر فعال می تواند تاثیر زیادی در میزان مصرف انرژی در مناطق مختلف داشته باشد. هدف از این پژوهش تعیین وضعیت آسایش حرارتی در شهر ایلام و ارائه راهکارهای ساختمانی متناسب با وضعیت اقلیمی این شهر است.روش بررسی: این پژوهش در سال 1397 با استفاده از روش توصیفی و شبیه سازی انجام شده است. برای دست یابی به ویژگی های معماری همساز با اقلیم در شهر ایلام از تحلیل داده های آماری 28 ساله (1393- 1366) ایستگاه سینوپتیک این شهر، ضوابط ارائه شده در چهار شاخص آسایش حرارتی استفاده شده است. نرم افزار Design Builder برای مشخص شدن میزان کمی تاثیر راهکارهای ارائه شده در شاخص های ماهانی و گیونی استفاده گردید.یافته ها: با به کارگیری راهکارهای غیرفعال ارائه شده در شاخص های ماهانی و گیونی، ساختمان می تواند هشت ماه از سال در طی روز و پنج ماه از سال در طی شب بدون مصرف انرژی در محدوده آسایش قرار گیرد. به علاوه جهت قرارگیری ساختمان، درصد نسبی بازشوها و استفاده از مصالح سنگین در دیوارها و سقف ها بیشترین تاثیر را در کاهش مصرف انرژی ساختمان دارند.بحث و نتیجه گیری: رعایت ضوابط ارائه شده در شاخص های ماهانی و گیونی در جهت گیری ساختمان و بازشوها می تواند سبب کاهش 20 درصدی در مصرف انرژی ساختمان شود، همچنین جایگزین کردن مصالح سنگین به جای مصالح متداول در جداره های ساختمان می تواند به میزان 39 درصد مصرف انرژی را کاهش دهد. به طور کلی با بهره گیری از اصول طراحی اقلیمی می توان به میزان 52 درصد میزان مصرف انرژی را کاهش داد.
چکیده انگلیسی:
Background and objective: About 44% of energy consumption is in the building sector and attention to thermal comfort indices and passive solutions can reduce energy consumption in different areas. The aim of this study is to investigate the thermal comfort situation in Ilam city and providing construction solutions appropriate to the climate of this city.Material and Methodology: In this study, a descriptive and simulation method was used. In order to achieve the architecture-compatible architecture of the climate in the city of Ilam, a 28-year statistical analysis (1988-2016) of the city's synoptic station, the criteria presented in four thermal comfort indicators have been used. The Design Builder simulator was used to determine the quantitative effect of the solutions presented in Mahani and Gioni indices solutions by thermal comfort indicators.Based on Mahani and Gioni indices.Findings: By using of the solutions presented in the Mahani and Gioni Indicator's, the building can be in the comfort zone for eight months from the year of the day and five months from the year without any energy consumption. In addition, building orientation, the relative percentage of openings and the use of heavy materials in walls and ceilings have the greatest impact on reducing the energy consumption of buildings.Discussion and Conclusion: Energy savings plans that are possible in the early stages of design (building orientation, openings) will result in a 20% reduction in energy consumption, according to the Mahani and Gioni indicators. In addition, replacing heavy materials instead of materials in common building walls can reduce energy consumption by 39%. In general, utilizing the principles of climate design can reduce the amount of energy consumption by 52%.Considering to the criteria given in the Mahani and Gioni indicators for building orientation and openings can reduce the energy consumption of the building by 20%. Reduce Also, replacing heavy materials with conventional building materials can reduce energy consumption by 39 percent. Overall, using climate design principles can reduce energy consumption by 52%.
