The Urban Design for Urban Block with Free Snow Cleaning in Cold andSnowy Cities Using Snow and Wind Simulations

在大雪寒冷的城市中，城区特别是公共区域道路和步行街的积雪清理耗费了巨大的精力和成本。因此，减少雪域城市的气体排放是雪域城市设计的必然要求。作者开发了减少札幌市市中心公共道路和人行道上积雪的街区设计。为减少市区清扫积雪的能量和CO2气体的排放，最理想的设计应该是紧密围合式的块状设计。

In the heavy snowy and cold cities, huge energy and cost have been spent for cleaning snow in urban area, especially in public area roads and pedestrian ways. Therefore cutting back on the emission of gases is required to the urban design in the snowy cities. Authors developed the block designs that reduce the snow accumulation on the public roads and pedestrian ways in downtown area Sapporo City. The block design with close rounding type should be most desirable design for reducing snow cleaning energy and emission CO2 gases in downtown area.
