Abstract

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