ملخص المقالة :

انرژی یکی از شاخص‌های مهم و موثر در راستای توسعه پایدار شهری است؛ چرا که توسعه پایدار با هدف تامین نیازهای انسانی، در راستای حفظ محیط زیست تلاش می‌نماید. بنابراین نمی‌توان از رابطه و اثرات مدیریت بهینه انرژی در بخش‌های مختلف شهری چشم پوشی نمود. در این پژوهش هدف بررسی اثرات و عوامل کاهش مصرف انرژی در توسعه پایدار شهر شیراز است. روش تحقیق توصیفی–تحلیلی و مبتنی بر داده‌های میدانی است. ابزار گردآوری داده‌ها پرسش‌نامه است. جامعه آماری را شهروندان شهر شیراز به تعداد 1565572 نفر تشکیل داده‌اند. بر اساس فرمول کوکران حجم نمونه به تعداد 384 نفر تعیین شد. همچنین برای شناخت و تحلیل عوامل کاهش مصرف انرژی در شهر شیراز از 21 کارشناس مرتبط جهت مصاحبه استفاده شد. روایی ساختاری و محتوایی پرسش‌نامه تایید و همچنین پایایی نیز با آلفای کرونباخ بالای 70/0 تایید شد. نتایج نشان می‌دهد که عوامل کاهش مصرف انرژی در توسعه پایدار شهری شامل 20 شاخص بوده است که در مجموع از طریق تحلیل عاملی در 5 دسته شامل کالبد و فرم شهری( 05/39)، گسترش خدمات عمومی شهری(25/21)، استفاده از انرژی‌های تجدیدپذیر(92/10)، ارتقای شاخص‌های اجتماعی(55/8) و سازگاری اقلیمی(25/7) شناخته شدند. همچنین بر اساس تحلیل محتوا، کاهش مصرف انرژی در توسعه پایدار شهری، 12 تاثیر عمده دارد که با استفاده از مدلسازی معادلات ساختاری، این تاثیرگذاری برابر با 76/0 می‌باشد. نتایج مدلسازی نشان می‌دهد که بیشترین تاثیرگذاری کاهش مصرف انرژی بر توسعه پایدار شهری مربوط به بهبود الگوی مصرف با مقدار اثرکل 88/0 و سپس حفظ محیط زیست با اثر 85/0، افزایش منابع سرمایه‌گذاری شهری با اثر 83/0 و همچنین مصرف بهینه انرژی در بخش ساختمان با اثرکل 82/0 بوده است.
