<div style="text-align: justify;">جدار خارجی ساختمان بهعنوان یکی از پارامترهای مؤثر بر تبادل حرارتی و میزان مصرف انرژی، همواره مورد بحث و بررسی بوده است. این پژوهش، باهدف بررسی مصرف انرژی و تأثیر مواد تغییرفازدهنده به­عنوان عایق بر رفتار حرارتی جدارهای خارجی یک ساختمان مسکونی و تعیین دمای ذوب بهینه در اقلیم سرد تبریز انجام شد. بدین­منظور، سه دمای ذوب 18، 24 و 28 درجه سانتیگراد انتخاب شد. روش انجام پژوهش، کمّی با رویکرد اثبات­گرایانه است. یک ساختمان مسکونی پنج طبقه در تبریز باتوجه­به در دسترس بودن آن انتخاب گردید. آنالیزها و شبیه­سازی­ها با افزونههای گرس­هاپر، هانیبی و لیدیباگ صورت گرفت. نتایج نشان داد که PCM با دمای 18 درجه باوجود کاهش مصرف انرژی 16/23 درصدی در ماه­های گرم، منجر به افزایش 44/1 درصدی نسبت به حالت پایه در ماه­های سرد شد. دماهای ذوب 24 و 28 درجه در ماه­های گرم به­ترتیب 93/31 و 48/20 درصد مصرف انرژی را کاهش دادند. کاهش مصرف انرژی در ماه­های سرد برای دماهای ذوب 24 و 28 درجه به­ترتیب برابر با 08/36 و 15درصد بود. بیشترین کاهش مصرف انرژی در کل ماه­های سال مربوط به جبهه جنوبی بود. به­طوری­که در دمای 18 درجه این کاهش به­ترتیب در ماه­های گرم و سرد به­ترتیب 65/61 و 80/61 درصد، در دمای 24 درجه 83/65 و 5/74 درصد و در دمای 28 درجه 53/62 و 94/61 درصد نسبت به حالت پایه بود. لذا، باتوجهبه اقلیم سرد تبریز، استفاده از PCM با دمای ذوب 24 درجه مناسب بوده و به لحاظ اقتصادی مقرونبهصرفه است.</div>

In this study, documents and plans of the studied building were taken and modeled in Rhino and Grass Hopper software. In these simulations, the weather data of Tabriz city was used and the process of analyzing and checking the amount of energy consumption was done through Honey Bee and Lady Bug plugins. Also, the number of users of the space (a family of 4) and the times used during the day (whole year) were considered.
