Analysis of Residential Building Layout and Its Impact on Building Energy Consumption in Hefei Region

Abstract

This article focuses on residential buildings in the Hefei region. Energy consumption simulations for different building layouts were conducted using ECOTECT and BECH software. Comparative analysis of simulation results was performed for three different conditions: winter, summer, and transitional seasons. The study aimed to identify the most energy-efficient building layout considering the local climate. The results indicate that for winter and summer conditions, the row-column layout is the most energy-efficient, saving 7.66% and 8.33% compared to enclosed and slanted layouts in winter, and 4.98% and 5.07% in summer. However, during the transitional season, an enclosed layout in April achieves the best energy-saving performance, while in October, the enclosed layout consumes 2.82% more energy than the row-column and slanted layouts. Overall, considering annual energy consumption, the row-column layout proves to be the most energy-efficient for residential buildings in the Hefei region, with energy savings of 4.28% and 3.5% compared to enclosed and slanted layouts, respectively, providing valuable in sights for energy-efficient design in residential buildings.
