چکیده
این مطالعه به ممیزی انرژی در یک ساختمان با کاربری اداری می‌پردازد که هدف آن، افزایش بهره‌وری انرژی و کاهش انتشار گازهای گلخانه‌ای است. در این راستا، از روش‌های غیر فعال (شامل تغییر الگوهای مصرف، عایق‌بندی، اصلاح ابعاد و موقعیت پنجره‌ها) و فعال (شامل بهبود کارایی سیستم‌های روشنایی و تهویه و جایگزینی منابع) استفاده شده است. بالاترین مصرف برق در این ساختمان به برق اتاق‌ها (4/55 درصد) و سیستم‌های سرمایشی (4/22 درصد) مربوط می‌شود و یخچال‌ها و سیستم‌های روشنایی ۹/۵۶ درصد از گرمای ناخواستۀ داخلی را تولید می‌کنند. نتایج نشان می‌دهد کاربست روش‏های فعال در کاهش مصرف انرژی سیستم‏های سرمایش و گرمایش و روش‏های غیر فعال در کاهش مصرف برق و گاز اتاق‏ها بیشترین تأثیر را داشته و مصرف برق و گاز به‌ترتیب 73/58 درصد و 39/59 درصد کاهش یافته است. بهبود الگوی استفاده از تجهیزات اداری و روشنایی، تأثیر بیشتری بر کاهش مصرف برق (۶/۸۱ درصد) داشته است. همچنین، ظرفیت کویل‌های گرمایش و سرمایش به‌ترتیب ۷۰/۵۷ درصد و ۶۹/۷۱ درصد کاهش می‌یابد. بیشترین مصرف انرژی در تأمین گاز داخلی برای گرمایش و برق برای سرمایش بوده که پس از اجرای استراتژی‌های بهینه‌سازی انرژی به‌ترتیب 89/7 و 97/33 مگاوات ساعت کاهش یافته است. بار اوج گرمایش و سرمایش نیز در صورت اعمال سیاست‏های پیشنهادی به‌ترتیب 8/88 درصد و 7/65 درصد کاهش و شرایط آسایش محیطی کاربران ۶۵ درصد افزایش خواهد یافت. این نتایج نشان‌دهندۀ اهمیت بهینه‌سازی مصرف انرژی در ساختمان‌ها و تأثیر آن بر بهبود شرایط زیست‌محیطی است.

چکیده [English]
This study focuses on the design and modeling of an office building aimed at increasing energy efficiency and reducing greenhouse gas emissions. In this regard, both passive and active energy methods have been employed, including changing consumption patterns, insulation, adjusting the dimensions and positions of windows, and improving the efficiency of lighting and ventilation systems. Analyses show that the highest electricity consumption in this building is attributed to electricity for rooms (55/4%) and cooling systems (22/04%). Additionally, refrigerators and lighting systems account for 56/9% of internal unwanted heat generation. The results indicate that by employing a combination of active methods in reducing heating and cooling energy consumption and passive methods in reducing electricity and gas consumption in office rooms, electricity and gas consumption will be reduced by 58/73% and 39/59%, respectively. Improving the usage patterns of office equipment and lighting has had a more significant impact on reducing electricity consumption (81/6%). Additionally, the capacity of heating and cooling coils will be reduced by 57/70% and 69/71%, respectively. The highest energy consumption is evident in providing gas for heating and electricity for cooling, which will decrease by 7/89 and 33/97 Megawatt-hours, respectively, following the implementation of energy optimization strategies. The peak heating and cooling loads have also decreased by 88/8% and 65/7%, respectively, resulting in a 65% increase in user environmental comfort. These results highlight the importance of optimizing energy consumption in buildings and its significant impact on improving environmental conditions.
