The Design of building envelopes consists of two major phases in two different disciplines are structural design and climatic design. This may be due to disjointed parameters that affect the design and optimization process, as well as different expertise of the designers and engineers in each field. Heinz Isler is an engineer who is studied about this subject and has designed extremely efficient shells with excellent performance over time. Considering his works, there are a few shell structures which have one or multiple apertures, mainly designed to introduce daylighting into the space. But how have these apertures influenced the structural performance of the shell. This paper intends to look at a perforated spherical concrete shell and assess its structural and daylighting performance. With constant thickness and building area and changing the half opening angle of the spherical shell structure. Then, the size, number and location of the openings is altered in order to observe the effect on the structural and environmental performance of the shell. Thegoal of this compatibility study is to demonstrate relation between topology, structural performance and environmentalperformance, and may be used by designers who consider multiple performance criteria in early design phases.
