چکیده مقاله :
ساختمان‌های مسکونی مسئول بخش قابل توجهی از مصرف انرژی در سراسر جهان هستند. ساخت هر مصالح و کاربرد آن در اجرای ساختمان انرژی مصرف می‌کند. این انرژی مصرف شده همان انرژی نهفته است که در کشور ما کمتر به آن پرداخته می‌شود. هدف این تحقیق کاهش مصرف انرژی نهان در ساختمان در راستای حفظ محیط زیست وتغییرات اقلیمی می باشد. در این مقاله با استناد به پیشینه تحقیق به کاهش انرژی نهفته با راهکارهای طراحی معماری پرداخته خواهد شد. ابتدا با توجه به مبانی نظری تحقیق متغیرهای مستقل تاثیر گذار تبیین می شوند. سپس انرژی نهفته یک ساختمان دراقلیم گرم ومرطوب شهر بندر عباس پس از مدل سازی مولفه های تاثیر گذار در قالب متغیرهای مستقل، متناسب با نوع ساختمان وخروجی های مقدار مصالح در نرم افزار اکسل محاسبه می‌گردد. نتایج در این مقاله شامل دو بخش نتایج نظری که محصول بررسی متون است و نتایج تجربی که از محاسبات حاصل شده و تحلیل گردیده است. دستاوردهای این پژوهش نشان می‌دهد که انرژی نهفته هر متر مربع ساختمان نمونه در موقعیت جغرافیایی و اقلیمی بندرعباس در بخش معماری 1.9 مگا ژول در هر متر مربع است که با تغییر متغیرهای طراحی تا 18.5 مگا ژول در هر متر مربع قابل تغییر می‌باشد؛ همچنین بیشترین درصد انرژی نهفته مربوط به دیوارها و کف‌ها است. نتایج این تحقیق الزام محاسبات و توجه به راهکارهای کاهش انرژی نهفته را در اقلیم گرم و مرطوب (بندرعباس) که نیاز به مصرف انرژی بیشتر دارند را برای دست اندرکاران ساختمان تاکید می‌کند .
