Effects of Vegetation Shading on Thermal Performance, Towards Sustainability in the Case of an Arid and Dry Area: A Plot In Biskra University Campus as a Case Study

This research, on external thermal ambiances, tends to highlight and affirm the impact of vegetation on outdoor thermal comfort, in an arid environment, which is very hot and dry.This effect of generating a less harmfully environment, in terms of thermal atmosphere, was emphasized by; in situ measurements and later, by simulations, in a semi-open public space with a set of mature Ficus Retusa trees, which were then cut later.This has given us an important opportunity for an intangible conclusion on the thermal ambiance by means of a comparison, within the same space, in other words, with the same morphological characteristics but in two different states; case "A" with the presence of trees and after these same trees have been cut; case "B".This helped to deduce the impact of persistent vegetation on thermal comfort in such an environment; we took the measurements before and just after cutting the trees and madecalculation of comfort index from climatic factors, themselves dependent on morphological indices.Theresults we got highlighted the variations in the comfort index (PMV), that is, an indicator of the thermal comfort in both cases.At last, we deducted the great effect of the trees shade on the external thermal wellbeing in a public space located in a very hot and dry zone.
