ABSTRACT

A large body of literature demonstrates that geometries with mathematically pure expressions are visually pleasing; however, there are fewer publications concerning how these relationships might be integrated into architectural design. This chapter aims to integrate these geometries with daylight when formed by the edge of light and shadow that result from direct sunlight entering a room through roof apertures and displays on northern walls. This chapter aims to investigate the potential of allowing architects to predict the resulting indoor shadow lines in an early stage during the design process. First, by describing a method to evaluate the degree of purity of lines. Next, by applying the described method to test the hypothesis that more geometrically pure combinations of northern walls and roof apertures’ configuration, as a starting point, will yield geometrically pure shadow lines. Finally, to extract a regression equation that opens an opportunity to develop a design decision-making representation tool that enables architects to predict the geometric purity of shadow lines in the stages of early design.
