Passive cooling potential of alley trees and their impact on indoor comfort

Abstract

The significance of vegetable shading is, that it can minimize the risk of overheating and also the negative effects of urban heat island. The aim of the paper is to analyze more precisely the shading effect of alley trees, and their impact on indoor comfort. The shading efficiency of trees is a species-specific attribute, because of the varying crown structure and leaf density. The analyses aimed the quantification of the transmissivity of characteristic individuals of three frequently planted species. On the base of measured data the cooling load of the buildings and the risk of summer overheating are calculated.
