Points to Ponder:

1. Do the new evaluation metrics that you’ve designed capture the meaningful differences between the building form alternatives?

I do think the new evaluation metrics that I’ve designed capture meaningful differences between the building form alternatives. As the value of mid-rotation angle increases, the floor area decreases and in turn the construction cost decreases. On the other side, cumulative insolation total value increases as the mid-rotation degree increases. These values offer the opportunity to weigh the differences between the models and consider what is most important to us. These new evaluation metrics create a fuller picture of my changing building form.

1. What other metrics would be useful to compute to help understand and make the case for which alternatives are truly better than others?

Some other metrics that I think would be useful to “make a case” for the better alternatives are daylighting potential, construction costs by material, and solar potential while considering shading surfaces. I wasn’t sure how to situate my building form within the site context, but I imagine surrounding buildings would have an impact on solar potential. Daylighting potential could also considerably decrease energy costs and construction material also have a large impact on cost. In the end, I feel like most things boil down to how expensive something is.
