Evaluation model for coupled urban local climate and buildings

Numerical modeling is an important tool to study urban-concerned problems. A thermal comfort and energy evaluation model is derived from revisions of a previous study, to simulate and predict the interaction of a coupled urban building-site climate. The methodology of principal calculations is demonstrated first, and then a hypothetical district of high-rise office buildings in Shanghai is selected. On-site climate parameters, anthropogenic heat and T_SE*, etc., are simulated and evaluated. The results show that during the air-conditioning period, the outside T_SE* value is strongly influenced by the set-point temperature of the air-conditioning system. When the set-point of the air-conditioning decreases from 28°C to 22°C, the anthropogenic heat increases 193 W/m² district, which gives rise to an increase of 0.23°C in outside T_SE*.
