Sustainability in Architectural Design - iterative process development

I am an architecture student doing an independent study on grasshopper to prepare for me thesis next year. The goals for the study are to develop tools to assist in generative design. I am trying to create grasshopper tools that will allow me to translate data from a spreadsheet into a iterations of visual representations (adjacency diagrams, program and circulation diagrams).
I am not exactly sure what the end result of my study will be but I am coming here in the hopes of finding people that have used grasshopper in the early stages of architectural design and picking their brain about the tools they have created to help guide the iterative process.
