The research of daylight environment of high-rise office building in central business district in tianjin
Tianjin is a representative city for many cities of North China. The daylight environment of high-rise building is also representative.To know the daylight environment there, we first investigated more than twenty buildings (including 536 offices) in Tianjin.then looked into uniformity of daylighting and environment arroudings and analysised the result to come at if there is a best orientation of office building in Tianjin. There is a distinguishing feature of cities which developing speed balances to Tianjin:high-rise buildings are pre-eminent to the surroudings. We made numerical simulations with AGI32, and at last give the ratio of different floors illuminance. From the simulation we find another regular pattern, the illuminance have a sharp descend when the depth is 1.3 times of the window height no matter which orientation it is.
