Abstract: In the context of the rural revitalization strategy, islands welcome new opportunities for tourism development due to their distinctive landscape advantages such as oceans and beaches, and the construction of rural public buildings to assist tourism is also becoming increasingly valuable. The characteristics of the sea breeze include fast wind speed, high wind frequency, steady direction, and long duration, and therefore natural ventilation can be used in public buildings to save energy and reduce emissions. This paper takes Yingming Village on Naozhou Island in western Guangdong Province as the research object, explores the design strategy of wind adaptability of island public buildings from the aspects of site selection, layout and orientation, building shape, functional zoning, and window opening through field research, problem and demand analysis, data simulation, and other steps. It has been discovered that using a decentralized layout, orienting buildings in the direction of the dominant wind, reducing the edges and corners of building blocks, arranging functions sensibly in accordance with ventilation requirements, placing climate buffer spaces, and adjusting the size of windows on the windward side can all help to effectively improve the ventilation effect on buildings both inside and outside. This strategy can provide a reference for the wind adaptability design of public buildings in similar island villages.
