چکیده

پنجره‌ها بخش قابل توجهی از اتلافات ساختمان را به خود اختصاص می‌دهند. استفاده از وسایل سایه‌انداز یک استراتژی مناسب جهت بهبود وضعیت مصرف انرژی در ساختمان‌ها ارزیابی می‌شود. در این مقاله مشخصات یک ساختمان اداری در شهر کرمان، در نرم‌افزار اسکچاپ مدل‌سازی شده است. سپس با مشخص نمودن مصالح، مدل ساختمان توسط نرم‌افزار اپن‌استودیو تکمیل شده است. در نهایت محاسبات مربوط به میزان مصرف انرژی در شرایط حضور سایه‌اندازهای ثابت خارجی و متحرک داخلی و همچنین بکارگیری همزمان آنها، در نرم‌افزار انرژی پلاس انجام شده است. نتایج نشان داد که استفاده از سایه‌اندازهای ثابت خارجی عملکرد به مراتب بهتری در راستای کاهش مصرف انرژی نسبت به سایه‌اندازهای متحرک داخلی دارند. دراین راستا سایه انداز ثابت خارجی با عمق (cm)150 با کاهش 92/18 درصدی در مصرف انرژی، بهترین نتیجه را به ثبت رسانده است. همچنین، استفاده همزمان سایه‌انداز ثابت خارجی با عمق (cm)100و سایه‌انداز متحرک داخلی پرده ساده با صرفه‌جویی (GJ) 57/63 در مصرف انرژی سالیانه ساختمان، بیشترین میزان کاهش مصرف انرژی را نشان می‌دهد.

چکیده English

Windows include a significant part of waste in buildings as they are transparent to solar heat and radiation. The use of shading devices is a suitable strategy to improve the energy performance of the building. In this article, specifications of an office building in Kerman are modeled in Sketch Up software. Then, by assigning materials to the building components in Open Studio software, the building is simulated. Finally, the building energy consumption in the presence of fixed external and, movable internal shading devices and simultaneous use of these two shadings, is calculated in Energy Plus software. Results show that the use of external shading devices has better performance in reducing energy consumption compared to internal movable shading devices. The external fixed shade with a depth of 150 (cm) has recorded the best result with reduction of 18.92% in annual energy consumption . The simultaneous use of external fixed shading with depth of 100 (cm) and internal movable shade with 63.57 (GJ) saving, shows the most reduction in annual energy consumption.
