چکیده
هدف اساسی این تحقیق شبیه سازی میزان کاهش مصرف انرژی جهت سرمایش فضای داخلی ساختمان در سناریوهای مختلف جهت گیری ساختمان، نسبت باز شو به دیوار، نسبت ابعادی و مواد پوششی نمای ساختمان در شرایط میکرواقلیم دو منطقه 12 و 22 شهر تهران میباشد. در این راستا با استفاده از مدل اقلیم معماری Climate Consultant، اقدام به شبیه سازی بار سرمایشی مصرفی فضای داخلی ساختمان در حالات مختلف جهت گیری ساختمان، نسبت باز شو به دیوار، نسبت ابعادی و مواد پوششی نمای ساختمان، برای دو میکرواقلیم متفاوت منطقه 12 و 22 شهر تهران گردید. در این راستا نتایج بدست آمده از مقایسه نمونه های موردی بررسی شده نشانگر کاهش مصرف انرژی گرمایی تا حدود 67% می باشد. همچنین نتایج شبیه سازی در طراحی واحدها با یک دیوار بیرونی به جای دو واحد می تواند به کاهش مصرف انرژی بین 25% تا 41% منتهی گردد. بنابراین تصمیمات معماری تاثیر بالایی بر مصرف انرژی در هر فضا دارند، نتایج تحقیق بیانگر آن بود که دو میکرواقلیم منطقه 22 و 12 تاثیر معنی داری در نیاز سرمایشی داخل ساختمان نداشته اند. نتایج حاصل از شبیه سازی فاکتورهای معماری ساختمان بیانگر آن بود که از لحاظ جهت گیری ساختمان تنها در صورتی که جهت گیری ساختمان شمالی باشد به صورت معنی داری بار سرمایشی ساختمان کاهش پیدا میکند در حالی که در جهات دیگر تفاوت معنی داری در کاهش بار مصرفی مشاهده نگردید و از طرف دیگر هرچه ابعاد بازشوها به دیوار کوچکتر میبود، میزان پرت انرژی سرمایشی داخل ساختمان کاهش یافته و بارسرمایشی داخل ساختمان کاهش پیدا میکرد.

چکیده English

In order to understand the total consumption of buildings and accurately calculate how much energy each building uses, taking in consideration all the building's lifecycle phases is essential. In order to select the correct methodology for the main study, the researcher began with the determination and the parameters that would have been researched, as well as the analysis and comparison of the different methods used by other researchers to achieve similar goals. The following parameters define the final results and are stabilized or examined to determine their actual effect: A- Constant parameters: 1- Climate data 2- and data on the use of the building: B- variables: 3- Design data: 1- orientation 2- window to wall ratio 3- aspect ratio. This research uses a survey followed by a computer modeling methodology to achieve the goal of providing architects with techniques that reduce energy consumption in building units. To obtain reliable results that are useful to the construction industry in the country, the researcher has ensured that the virtual environment created in the modeling process mimics a typical building environment of Tehran units. Research has shown that passive design techniques have a major impact on the energy consumption of buildings. A significant reduction in consumption (67 percent) was noted when the orientation and percentages of the opening on the wall were changed. In summary, this study has shown that the application of passive, economical and simple design techniques has a major impact on the energy consumption of the unit rooms. If the architects take these ideas into account during the design process, the buildings will take on more responsibility for the environment and consequently reduce carbon dioxide emissions.
