Research On The Passive Thermal Insulation And Cooling Design Strategy On Public Buildings In The Lingnan Area

It's meaningful to propose the passive thermal insulation and cooling design strategy on public buildings in the Lingnan area in the case of the global energy and environmental crisis situation, the trend of large and quick construction of public buildings in China, and the higher energy consumption of public buildings in the Lingnan area because of the climate and economic development.Based on research of existing domestic and foreign passive insulation and cooling design strategies, traditional buildings in the Lingnan area, and climatic characteristics of the Lingnan area combined with natural geographic and cultural features, the integrated passive thermal insulation and cooling design pattern on public buildings in the Lingnan area has been proposed. And then, the writer put forward to the appropriate passive thermal insulation and cooling design strategy on public buildings in the Lingnan area based on it. Specific results are as follows:The appropriate passive thermal insulation design strategy on public buildings in the Lingnan area:external sun-shading of window and door openings including south, north, east, west and roof o f buildings, internal sun-shading of window and door openings, building self-shading and shade pants design strategies are proposed. It's also acquired passive thermal insulation design strategies on external structure of public buildings.The appropriate passive cooling design strategy on public buildings in Lingnan area:natural ventilation strategies based on shape, plane and space organization, and external structure of buildings are proposed. It's also acquired passive cooling design strategies on making full use of the principle of liquid evaporation, plant characteristics and other ways.The integrated passive thermal insulation and cooling design pattern and strategy on public buildings in the Lingnan area:the pattern aims to make the passive thermal insulation and cooling design on public buildings in the Lingnan area linked to other various design factors. The technical suitability, function compatibility and regional humanities should be taken into account on the integrated passive thermal insulation and cooling design strategy.
