Height correction factor for air conditioning load of super high-rise buildings in different climatic zones
Chen Liang
The wind velocity increase and temperature decrease affect the air conditioning load of super high-rise buildings, and the influence degree depends on the climatic zone where the building is located. Studies the height correction factors of summer cooling load and winter heating load through the exterior wall, roof and skylight in Harbin, Shenyang, Beijing, Shanghai and Guangzhou, which are selected from five climatic zones. The results show that the summer cooling load is little affected by wind velocity increase, and the cooling load decrease due to wind velocity increase and temperature decrease might be considered as the safety margin of summer cooling load, so the height correction factor of summer cooling load could be ignored in the calculation. The winter heating load is greatly affected by wind velocity increase, especially by temperature decrease, and the height correction factor of southern region is larger than that of northern region. The height correction factors for the exterior wall of tall building with the height of 500 m in Harbin, Shenyang, Beijing, Shanghai and Guangzhou are respectively 8%, 9%, 12%, 15% and 22%.
