本文利用开发的城市区域热气候计算模型,针对高纬度严寒地区建筑容积率对局地热气候和室外热舒适性的影响进行了动态数值模拟。结果表明:多层建筑容积率的增加有利于改善冬季局地热气候和室外热舒适性;而对于高层建筑住区来说,容积率超过3.0时,将会对局地风速和太阳辐射造成大幅衰减。以上结论为更好地利用容积率对该地区进行开发和可持续发展提供了数据支撑。
In this paper, the developed model of urban regional thermal climate calculation is used to simulate the influence of the building volume ratio on the local thermal climate and outdoor thermal comfort in high latitudes and cold regions. The results show that the increase of multi-story building volume ratio is favorable to improve the local geothermal climate and outdoor thermal comfort in winter. For the high-rise residential buildings, the volumetric rate of more than 3.0 will greatly reduce the local wind speed and solar radiation . The above conclusions provide data support for the better utilization of plot ratio in the development and sustainable development of the area.
