Ecological aesthetic of wind environment about the circular earth building in Fujian,China

Green building has become the trend of urban development in the twenty-first century as the threat of global warming is ever more challenging. The traditional Tulou in Fujian, China, characterized by its distinct building form and local culture is an outstanding representation of ecological building. From the perspective of ecological aesthetic, this research discusses the aesthetic factors of wind environment of Eryi Lou, the largest Tulou in Fujian. Starting from the GIS analysis on the overall environment, also assisted by MapInFo, this research further analyzes the external and internal wind environment of the Eryi Lou through site measurement of the building's ventilation efficiency. Results showed that building form of Eryi Lou corresponded with topography and landform, as well as life wisdom of symbiosis with the environment and meets the requirements of ecological aesthetics criteria of both local characteristics and national character. The design of the major entrance with Feng Shui-oriented axis, as well as the design of courtyard in the quadrangle, circular corridors, and windows on the forth-storey are all intended for better cross-ventilation and heat dissipation. Such a design is a combination of aesthetics and human-based functional use, proving that Eryi Lou is an ecological building corresponding to the concept of ecological aesthetics, is an exemplar of symbiotic relationship between modern city development and environment.
