چکیده مقاله :
زمینه و هدف: مفهوم ساختمان صفر انرژی در حال توسعه است اما این ساختمان باید ب شرایط مختلف آب و هوایی سازگار باشد. ساختمان‌های مناطق سردسیر بخصوص شهر تبریز به دلیل مصرف زیاد انرژی گرمایشی در فصل زمستان، مصرف انرژی و انتشار گاز بیشتری دارند. طراحی و راه اندازی یک ساختمان با انرژی صفر خالص در آب و هوای سرد بسیار چالش برانگیز است. این مقاله تحلیل الگوی یک ساختمان اداری صفر انرژی را با هدف بهرهوری انرژی و پایداری محیطی مورد بحث قرار می دهد. براین اساس ساختمان اداری پسماند شهری تبریز مورد بررسی قرار گرفت.
روش کار: روش تحقیق حاضر توصیفی-تحلیلی و با هدف کاربردی می باشد. برای تحلیل از نرم افزار شبیه ساز انرژی پلاس استفاده شد. شبیهسازی ساختمان برای تایید محیط روشنایی داخلی و مصرف انرژی سالانه انجام می شود. تراز انرژی برای مطالعه موردی، با هدف دستیابی به هدف انرژی الکتریکی با انرژی صفر محاسبه شد. نظارت دقیق انرژی در حین عملیات اجرا می شود.
یافته ها: کل مصرف انرژی سالانه ساختمان شبیه سازی شده بسیار کمتر از اتاقهای فعلی ساختمان میباشد. با توجه به نتیجه شبیهسازی ارائهشده توسط انرژیپلاس، میزان مصرف انرژی سالانه 195505 کیلو بیتییو (57297 کیلووات ساعت) است که عمدتا از طریق بار گرمایشی در فصل زمستان انجام میشود. همچنین نتایج نشان داد بهبود گرمایش و تهویه مطبوع و روش کنترل خصوصاً بر پایه نتایج پایش بسیار دقیق دادهها است.
بحث و نتیجه گیری: برای دستیابی به ساختمان پایدار واقعی در اقلیم سرد، تحلیل چرخه حیات نیز برای دستیابی به عملکرد زیستمحیطی ساختمان هم باید انجام گیرد. تا یک ساختمان پایدار صفر انرژی در اقلیم سرد شکل بگیرد.
Background and aim: The concept of zero energy building is being developed, but this building must be adapted to different weather conditions. Buildings in cold areas, especially in Tabriz city, have more energy consumption and gas emissions due to the high consumption of heating energy in the winter season. Designing and operating a net zero energy building in a cold climate is very challenging. This article discusses the analysis of the model of a zero energy office building with the aim of energy efficiency and environmental sustainability. Therefore, the administrative building of urban waste in Tabriz was investigated.
Methods: The current research method is descriptive-analytical and with practical purpose. Energy Plus simulator software was used for analysis. The simulation of the building is done annually to confirm the indoor lighting environment and energy consumption. The energy balance for the case study was calculated with the goal of achieving zero energy electrical energy. Strict energy monitoring is implemented during operation.
Results: The total annual energy consumption of the simulated building is much lower than the current rooms of the building. According to the simulation results provided by Energy Plus, the annual energy consumption is 195,505 K-BUT (57,297 KW-hours), which is mainly done through the heating load in the winter season. Also, the results showed that the improvement of heating and air conditioning and the control method is especially based on the results of very accurate data monitoring.
Discussion and Conclusion: To achieve real sustainable building in cold climate, life cycle analysis should also be done to achieve the building's ecological performance. To create a sustainable zero energy building in a cold climate.
