On Geometric Form Genesis Directed by Buildings' Efficency- Canton Tower Case Study

Abstract

Lately, energy efficency in architecture and urbanism has played a crucial role. Wind and facade exposure to sun, being important elements of energy efficency particularly in the sense of energy renewability, might produce significant obstacles if not properly estimated in the process of designing and up building. Thus the creation of optimal geometric form is very important for further proper functioning of the building. The final geometric form when created applying various geometric transformations or deformations from starting basic forms (such as prisms, cylinders, cones, etc .) might be easily investigated in the sense of sunlit and its constructive stability under wind influence using any various software, for example VASARI for the sake of effecient energy consumption. In the paper we discuss the process of deriving the geometric form of the Canton Tower, Guangzhou, China, with respect to insolation and wind gust following the change of iso-photes and wind iso-gust lines in accordance with the geometric form derivation.
