Constructive, aesthetical and psychological criteria for glass roof design

Abstract

The application of glazing allows the construction of very transparent roofs. To determine a transparent structure the lightness is a measurable factor within the subjective experience of transparency. At the example of transparent space grid structures with axial load-bearing glazing the interaction between measureable transparency, percept transparency and constructive criteria is analyzed. The constructive criteria include different parameters as pre-assembling, stability, member length, knot geometry and joint sealing. The measureable transparency criteria include lightness and transparency values due to contrast investigation and the percept transparency bases on a psychological study of 325 people assessing film sequences of 3D environments.
