The paper discusses the importance of greenery in cities. It considers the presence of green elements inside a typical urban perimeter block and deliberates about their impact on the solar radiation level on the facades and the yard. A series of computer simulations have been done using six combinations of surface reflectance (façade/yard) for six perimeter block configurations. The simulations were performed with DIVA, a plug-in for Rhino for Oslo (59.91273, 10.74609). The results confirm that a modest amount of greenery causes only a small reduction of the radiation, up to 11% in the yard and up to 13% in the lower parts of facades. Surface reflectances are important. The increase of façade reflectance from 22% to 66% is more than enough to compensate for adding green elements, e.g. one large birch and three smaller ever-green conifers.

绿化和表面反射率对周边街区太阳辐射的影响

该论文讨论了绿色植物在城市中的重要性。它考虑了典型城市周边街区内绿色元素的存在,并考虑了它们对外墙和院子的太阳辐射水平的影响。已经使用六种表面反射率组合(立面/庭院)对六种周边块配置进行了一系列计算机模拟。模拟是使用 DIVA 进行的,它是 Rhino for Oslo (59.91273, 10.74609) 的插件。结果证实,少量的绿化只会导致辐射的小幅减少,在院子里减少了 11%,在立面的下部减少了 13%。表面反射率很重要。立面反射率从 22% 增加到 66% 足以补偿添加绿色元素,例如一棵大桦树和三棵较小的常绿针叶树。
