Assessment criteria for form environmental performance of building envelope in hot arid climatesud

摘要

This paper represents the methodology carried out for the investigation of a part of audmultiphase experimental research work that examines the effect of various forms and geometries ofudbuilding envelope elements on indoor environments under given summer or winter conditions. Theudresearch also includes the influence of outer envelope form upon indoor thermal conditions, externaludand internal solar behaviour, natural ventilation and day lighting performances under particularudclimatic conditions. The different phases aim at investigating large number of roof and wall formsudusing different measurement tools and techniques; onsite and experimental investigations,udlaboratories rigs, and computational simulations. The research-project considers the environmentaludproperties of spaces enclosed by different architectural forms and geometries in order to find outudtheir Forms’ Environmental Performance (FEP). The lack of appropriate tools for environmentaludinvestigations of some building-envelope forms and their internal and external environmentaludrespond scenarios are identified along with better understanding of form environmental benefits. Thisudresearch has been carried out on various curved roof forms being the most popular roof form in hotudarid regions; in this paper the conical roof form will be discussed in more detail.
