Yüksek katlı konutun dış cephe malzemeleri için karşılaştırmalı enerji simülasyonu: Isınma ve soğuma verimliliği analizi

The interest in building energy performance and efficiency has been increasing in the last decades. Although several studies on energy-efficient buildings exist in the architecture, engineering, and construction (AEC) literature, none of them addressees the heating and cooling performance of high-rise building envelope materials. Such research would be a valuable guideline for the early decision-making process in energy-efficient high-rise building design. This study aims to (1) build up a knowledge base for exploring the optimal building envelope components based on the relevant aspects of energy performance to design energy-efficient high-rise buildings and (2) analyze and compare the effects of three different building envelope materials (i.e., reinforce concrete, timber wall, and curtain wall) on energy performance of a high-rise residential building. For this purpose, first, Cite Space, VoSViewer, and Gephi were used for building up a knowledge base in building energy performance. Then, various scenarios for evaluating the impact of envelope components (e.g., wall structure, window-to-wall ratio, and site orientation) were developed and analyzed. Efficient scenarios were opted for developing analyses in terms of floor, roof, and glazing type to decrease the heat loss/gain in the roof, floor, and glazing. Design Builder was utilized to design and model the case study building based in Istanbul, Turkey, and perform energy analysis for its heating and cooling efficiency by focusing on walls, roof, and ceiling (considering the building's orientation), window-to-wall ratio (WWR), and insulation. This research contributes to the AEC literature and industry by providing (1) detailed information about influential factors in heat loss/gain, (2) the factors to achieve energy efficiency and to decrease heating and cooling demand in high-rise buildings, (3) combinations for energy efficient building envelope materials, and (4) knowledge base for an efficient heating ventilation air conditioning system design for high-rise residential buildings. Accordingly, the results would be very useful for assisting professionals in the decision-making process of energy-efficient high-rise residential building design. Further, this study reveals promising topics in this scope for future research.
