چکیده مقاله :
با در نظر گرفتن اقلیم منطقه، طراحی ابعاد و تناسبات پلان بنا و قرارگیری مناسب ساختمان، سبب کاهش بار حرارتی، برودتی و بهبود برخورداری ساختمان از تهویه طبیعی می گردد. در این مقاله یک نمونه موردی ساختمان اداری در اقلیم معتدل و مرطوب شهر رشت با نرم افزار Designbuilder 5.4 شبیه سازی و مقادیر تهویه طبیعی و انرژی مصرفی کل سالانه آن محاسبه می شوند. هدف، تحلیل وضعیت موجود، ارائه پیشنهاد بهبود رفتار تهویه- انرژی مصرفی بر اساس تناسبات پلان، جهت گیری و ارائه الگوهایی جهت طراحی ساختمانهای اداری در اقلیم معتدل و مرطوب است. بر این اساس ساختمان مورد مطالعه در 7 جهت مختلف جنوبی، 45، 30 و 15 درجه جنوب شرقی و غربی شبیه سازی و مقادیر تهویه و انرژی مصرفی سالانه محاسبه می شوند. در مرحله بعد با پیشنهاد تغییر شاخص تناسبات پلان ساختمان مورد مطالعه از 2:3 به 1:3، 1:2 و 1:1 ، شبیه سازی هر یک به ازای 7 جهت مورد نظر انجام می شود. کمترین میزان انرژی مصرفی کل سالانه ساختمان با شاخص تناسب1:3 و جهت گیری شمالی-جنوبی و بیشترین مقدار تهویه طبیعی نیز با همین شاخص تناسب در جهت گیری 30 درجه جنوب غربی و جنوب شرقی حاصل می گردد. همچنین با هدف تحلیل کمی مقایسه ای شاخص های تغییر تهویه و انرژی مصرفی به ازای تغییر جهت برای چهار شاخص تناسب محاسبه می شوند. بیشترین شاخص تهویه به ازای کمترین شاخص رشد انرژی مصرفی در شاخص تناسب 1:2 به ازای زاویه 15 درجه جنوب شرقی و غربی حاصل می شود.
Considering the region's climate, designing the dimensions and proportions of plans and proper location of buildings reduce the thermal and cooling load, and improve natural ventilation of buildings. Accordingly, in this paper, an office building in the temperate and humid climate of Rasht was simulated using DesignBuilder 5.4, and the natural ventilation and total annual energy consumption were calculated. The aim of the study was to analyze the existing situation, propose methods to improve the ventilation-energy consumption behavior based on plan proportions, orientation, and, present models to design office buildings in temperate and humid climates. Therefore, the building was simulated in seven different orientations, namely south, 45, 30 and 15-degree southeast, and west, and the values of ventilation and annual energy consumption were calculated. Then, it was proposed to adjust building plan proportions from 2:3 to 1:3, 1:2, and 1:1, to simulate each proportion for 7 different orientations. The lowest total annual energy consumption was observed in a building with a 1:3 proportion and north-south orientation, and the highest natural ventilation with the same proportion was obtained in 30-degree southwest and southeast orientations. Furthermore, changes of ventilation and energy consumption indices were calculated for the changes in four proportions in order to conduct a comparative quantitative analysis. The highest ventilation index was obtained for the lowest energy consumption growth index in 1:2 proportion for 15-degree southeast, and west orientation.
