"夏氏遮阳"与岭南建筑防热

50年前,夏昌世教授建立了岭南现代建筑的防热理论并付之实践,留下了新建筑窗口遮阳和屋顶遮阳的先例,这一创举被称为“夏氏遮阳”。夏氏遮阳虽有缺点,但体现了岭南建筑防热方向,所以应该发展。岭南现代建筑防热主要有隔热和散热两种途径。隔热分为遮阳隔热、结构和构造隔热、室内遮热板隔热三方面;散热又分通风散热、辐射散热、导热散热三方面。当代岭南建筑防热之路应该是：自然降温与人工空调相结合;遮阳与遮雨相结合;学习传统,大距创新。

"Xia Changshi's Sunshade" and Lingnan Architecture Heatproofness

50 years ago, Professor Xia Changshi established the theory of Lingnan neoteric architecture Heatproofness and practice it. He gives us a precedent of sunshade for windows and roofs. To commemorate this pioneering work of Lingnan architecture, we call it "Xia Changshi's sunshade".It shows the way of Lingnan architectural heatproofness and should be developed though it has shortcoming. There are mainly two ways in Lingnan neoteric architectural heatproofness - heat insulation and heat dissipation. Heat insulation has three ways: by sunshade, by constitution and structure, by indoor heat shelter; heat dissipation also has three ways: by ventilation, by radiation and by heat conduction. The way of heatproofness for contemporary Lingnan architecture should be like this: natural cooling works with air condition, shelter for sun-radiation and rain. We should learn from the tradition and innovate intrepidity.
