The impact of greenery and surface reflectances on solar radiation in perimeter blocks
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.
