چکیده

آسایش بصری  در فضاهای اداری به ویژه در مناطق شهری پر تراکم و سایه اندازی بناهای مجاور اهمیت زیاد دارد. برای طراحی مناسب روشنایی آگاهی از سطح روشنایی مطلوب ضروری است. در حال حاضر در ایران، این محدوده برای فضاهای اداری تعریف نشده است و متخصصین برای جبران این نقیصه به یافته‌های دیگر کشورها رجوع می‌کنند. به دلیل تفاوت‌های اقلیمی و تفاوت فرهنگ استفاده از روشنایی، ممکن است یافته‌های دیگر کشورها برای ایران مناسب نباشد. از این رو پژوهش پیش‌رو به دنبال تعریف محدوده رضایت‌مندی از شدت روشنایی در ساختمان‌های اداری شهر تهران است. روش استفاده شده پیمایش و مطالعات میدانی است. به همین منظور تعداد ۵۰۹ پرسشنامه در دو فصل تابستان و زمستان، در ۱۴۶ اتاق در تابستان و ۱۰۹ اتاق در زمستان توسط کاربران در شش ساختمان اداری با ویژگی‌های مختلف از جمله یک طبقه تا سیزده طبقه، پلان باز و با اتاق‌های خصوصی، نوساز و قدیمی، به منظور ارزیابی شرایط روشنایی محیط تکمیل شدند. هم‌زمان با تکمیل پرسشنامه توسط کاربران، پارامتر فیزیکی شدت روشنایی در سطح میز کار کاربران، اندازه‌گیری شدند. از روش‌های آماری مرتبط در نرم افزار SPSS برای تحلیل داده‌ها و یافتن ارتباط بین متغیرهای تحقیق، استفاده شد. نتایج نشان می‌دهد که شدت روشنایی مطلوب در این فضاها ۶۰۰ تا ۶۵۰ لوکس است و شدت روشنایی بین ۵۵۰ تا ۶۰۰ لوکس نیز شرایط آسایش را فراهم می‌کند. شدت روشنایی کمتر از ۵۵۰ لوکس برای کاربران مطلوب نیست.
