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

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