Abstract

Under the background of increasingly serious energy crisis, promoting the development of building energy conservation can effectively alleviate the problem of an energy shortage, ensure stable economic development, and energy-saving design has gradually become a major component of building design. In this study, the numerical simulation method was used to take a building with typical features in Hefei as the research object, and the Ecotect energy analysis software was used to systematically analyze the influence of different orientations on the annual building energy consumption. The study found that the impact of building orientation on energy consumption showed a significant linear relationship. As the outdoor temperature increased, the cooling load gradually increased, and the heating load gradually decreased. Among them, the total energy consumption load was the smallest when the building orientation was southwest 15°, and the total energy consumption load was the largest when the building orientation was east-facing. The research results provide a reference for the energy-saving design of buildings in different orientations in the Hefei region.
