- Cost of Construction by surface area ($500 to $1000 cost linearly increases from ground level to 750 feet).
- Solar Insulation Calculations for all nonground surfaces

Points to Ponder:
- 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.
- 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.
