Developing a system for evaluating roof shape design

Considering problems in the processes of roof design, a system for evaluating the performances of roofs is presented in this paper. Based on a basic analysis of the primary geometric figures, which simplified from 10 roofs of Japanese Wooden Detached House (WDH), application of the Topology theory in roof design is founded. Adapting the continuous transformation character of Topology theory, Genetic Algorithm (GA) is selected to have simulations on varied roofs derived from a suitable Basic Model (BM) and utilized to search for efficient roof for meeting our Indices. To certificate the validity of the developed system, a sample trail by operating a Curved Roof Surface Model (CRSM) for obtaining an optimal roof to minimization thermal loads from roof is proposed.
