First try at octopus, Parametric void

Hi everyone!
This is my first post on the forum and I wanted to discuss my first ever octopus definition I worked on.

I'm trying to minimize radiation while maximizing daylight to generate a form for a commercial building.

Catch is, I've tried to introduce a void geometry and added its geometric parameters into the genome as well.

Could someone look at it and see if the workflow makes sense? I currently don't have a powerful PC at work to test it. 

Is there anything I should improve/streamline/change in order to hasten the process?

Ps. GH file attached below. 

I've used a custom cluster by yazdani studio in two places for mass building. 

Thanks a ton!
