امکان‌سنجی تغییر کاربری عمارت قاجاری قزاقخانه بر اساس ارزیابی آسایش بصری

عمارت قاجاری قزاقخانه به عنوان اولین بنای اداری تهران ضمن تغییر کاربری، به عنوان دانشگاه هنر مشغول به فعالیت می باشد. هدف این پژوهش بررسی وضعیت آسایش بصری نوری این بنا با توجه به استانداردهای مورد نیاز در کاربری های اولیه و ثانویه آن است. حال این سوالات مطرح می باشند: از منظر گواهینامه سنجش اعتبار leed v.4 option 1 وضعیت شاخص های sda و ase در این بنا چگونه است؟ و آیا شرایط آسایش بصری نوری این بنا جهت کاربری های اداری و آموزشی مناسب می باشد؟ روش این پژوهش توصیفی- تحلیلی به همراه بهره گیری از شبیه سازی نرم افزاری می باشد. به منظور ارزیابی آسایش بصری نوری، شاخص های کفایت نور روز فضایی (sda) و تابش سالانه نور خورشید (ase) در بنای مذکور مورد بررسی قرار گرفته اند. مدل سازی توسط نرم افزار designbuilder v6.0.1 صورت گرفته و نتایج در قالب گواهینامهleed v.4 option 1 تحلیل شده اند. طبق نتایج، آستانه آسایش بصری نوری جهت کاربری های مذکور در این بنا احراز نشده است.

feasibility of changing the application of the qajar mansion of qazaqkhaneh based on the assessment of visual comfort

historical heritage is a valuable asset, and preserving it for future generations is considered a duty. ignoring historical monuments can cause their deterioration, and handling and reuse are useful in preserving them. during the qajar period, after the transfer of the capital to tehran, various government buildings were built there. the qazaqkhaneh mansion, located in mashgh square, is mentioned as the first administrative building of this city. today, this building is used as an art university, having been repurposed for education. the revival of historical buildings, apart from retrofitting problems, also faces performance challenges. research shows that architects, by mastering climatic and environmental principles, have been able to create thermal comfort in different uses, but less effort has been made in the field of visual comfort. considering that, on the one hand, the activities of administrative and educational applications often take place during daylight hours, and on the other hand, the lack of visual comfort reduces the productivity of users, it is necessary to assess this factor in the building. its ability to be restored or changed to the new application should be reviewed. as the first administrative building of tehran, qazaqkhaneh building is operating as an art university, so it seems necessary to evaluate its initial function and ability to revive it as an educational use by evaluating daylight and glare. now these questions are raised: from the point of view of the leed v.4 option 1 accreditation certificate, what is the status of the sda (spatial daylight autonomy) and ase (annual sun exposure) indicators in this building? and are the optical visual comfort (ovc) of this building suitable for office and educational applications? the method of this research is descriptive-analytical with the use of simulation. in order to evaluate the optical visual comfort, the indicators of sda and ase have been investigated in the mentioned building. modeling and simulating were done by design builder software and the results were analyzed in the form of leed v.4 option 1 accreditation certificate. in this regard, the office part of the first floor located in the west wing of the qajar mansion along with the physical elements of the shell (windows) has been carefully modeled and simulated by design builder. in the following, the results of daylight and glare simulation using dynamic indicators of sda and ase have been analyzed and interpreted based on the leed v4.0 option 1 accreditation certificate. as a result, it is stated that the condition of the sda index in all 6 office rooms is unfavorable from the point of view of the leed v.4 option 1 credit assessment certificate, and also the condition of the ase index is in favorable conditions only in the north front rooms, which without simultaneously verifying the minimum value of the sda index in these spaces, it is worthless. also, based on the evaluation of this credit assessment certificate, the state of visual and optical comfort in this building is not suitable for administrative and educational uses.
