Abstract
As a result of the impact of energy consumption, research on ultra-low energy, nearly zero-energy, and zero energy buildings has been conducted in China. However, the design of the nearly zero-energy building is flexible; the traditional architectural design method is not fully applicable to nearly zero-energy buildings. The paper proposed a performance-based design method based on overall energy consumption and progress for the nearly zero-energy building. The design process of the relevant cases was also analyzed. The factors of cold and heat sources, environment, and renewable energy were combined to make a comprehensive analysis to get the optimal scheme of the nearly zero-energy building in the case. In general, the performance-based design method has a certain guiding significance for the design of nearly zero-energy buildings and certainly promotes the expansion of the nearly zero-energy building industry in China.
Highlights
With the development of the social economy, the urbanization process has rapidly advanced, and the living standards for humans have continuously improved
This paper investigates the design requirements and characteristics of nearly zero energy buildings to study and analyze the systematic design method and process of nearly zero-energy building development, which provides some guidance for the promotion and engineering application of nearly zero-energy buildings in China
Using the design method in an actual case, the final project energy saving rate was 62.84% comparing with the reference building and achieved design standards for nearly zero-energy buildings
Summary
With the development of the social economy, the urbanization process has rapidly advanced, and the living standards for humans have continuously improved. This has resulted in high energy consumption and a large number of pollutant emissions. In China, the energy consumption of building operations occupies about 20% of the total energy consumption of the whole country [1]. There are two main directions for building energy conservation, namely “developing sources” and “reducing consumption”. “Developing sources” refers to the development and use of new energy sources, while “reducing consumption” refers to the reduction of building energy consumption through new techniques
