Study On The External Shading With Metal Components For Australian Buildings

It is currently a global trend to save energy in all areas. As an important technique forenergy efficient buildings, external shading is widely used throughout the world. Althoughshading is increasing popular, in China its methodology and techniques are still pre-mature.Technically the shading structures with concrete components suggested by Xia is popular.When it comes to shading with metal components, there are also some applications. However, most techniques involved are introduce from abroad directly without innovations. The potential benefits of shading with metal components are not optimized.More often than not, the external shading components cannot become a harmonic partof building elevation.The practice of sun shading in Europe has drawn much attention from internationalarchitects. However, Australia has similar climate as China. In recent years, Australianarchitects have made impressive progress in combining the elevation styles with externalshading with metal components. Their experience is valuable for Chinese architects,especially in the design of buildings in south China, where the climate is hot and humid.This thesis generalizes the development of sun shading in Australia first. After thatsome recent and representative examples of external shading with metal components arestudied. Then the effectiveness of these shading styles and their influence on lighting andventilation are analyzed under the climate of both their original places and south China,with the help of numerical simulation software. Comparisons are also made with ordinaryshading styles in China.Following results have been obtained:1.The state-of-the-art and future of external shading with metal components inAustralia are concluded together with local climate and culture. Specifically speaking,Australia is rich in metal, which is easy to be processed into different shapes. Thus metal iswidely use for eternal shading components, which improve the energy efficiency ofbuildings and represent local culture and art. 2.With proper simulations, Australian external shading styles adopted both in theirlocal climate and in south China are compared with respect to the effectiveness andinfluence on lighting and ventilation. The adaptability of these shading styles to hot andhumid climate in China is discussed.
