Research on the coupling relationship between energy consumption and architectural form design of university dormitory buildings under the target of low energy consumption

Abstract

In response to the challenges of global climate change, promoting low-carbon and green sustainable development has become a key direction for urban construction. With advancements in technology and methods, research on building energy consumption has gradually expanded from individual buildings to urban and block scales. This study regards dormitory areas as functionally unified blocks. From the perspective of block scale, taking Xi ’an, a cold area in China, as an example, through typical case study, field investigation and Rhino-UMI (Urban Modeling Interface) tool, energy consumption simulation of dormitory buildings was carried out to analyze the impact of building layout, spacing and orientation on energy consumption. Based on the target of low energy consumption, architectural form design strategies were proposed, and their effectiveness was verified through case optimization and energy consumption simulation. The coupling relationship between the two was discussed. The results show that for high-rise dormitory areas, enclosed layout is more energy-efficient; in a parallel layout, the gable spacing is positively correlated with energy consumption, with 20-meter spacing selected for design, cooling, heating and total energy consumption are the lowest; for a vertical layout, the most energy-efficient gable spacing is approximately 24 m; moderate increases in building height can reduce energy consumption, in the case of meeting the relevant control indicators, high-rise dormitory area height in the 11–18 floors, a higher building height can be selected on the basis of the design; the optimal direction of the parallel arrangement layout is due north and south; the optimal orientation of the enclosing type is 15° south by west.
