以热环境优化为目标的控制性详细规划编制技术

The exploitation of technology of regulatory detailed planning aiming at optimization of thermal environment

通过分析控制性详细规划传统指标与热环境影响因子的关系,在建筑密度、容积率和绿地率等指标的基础上,提出天空角系数、不透水率、绿化覆盖率等热环境评估补充指标,并运用计算机数值模拟方法 DUTE和Fluent,模拟限定条件下的容积率奖励案例对近地面风场、温度场的影响,直观地展示容积率奖励机制在热环境控制方面的价值,为控规编制技术提供新的思路。

The relationship of existing indicators and thermal environmental impact factors was analyzed,and the assessment indicators were proposed,which were,building density,floor area ratio,greening rate,sky view factor,impervious rate and greenery coverage rate. Control standard classification of thermal environment and quantification of indicators were also described. In addition,the feasibility of floor area ratio incentive mechanism was confirmed by using computer numerical simulating method DUIE and Fluent,and the applicable conditions were put forward.
