 Yeah, the main push was twofold, and it was to balance a reduction in energy use and then a production of clean energy. We found that doing one or the other didn't get us to where we wanted to go, and yet working with local builders and engineers, we found that dialing both of those together was a really powerful recipe. The way we engineered it was we modeled out exactly how much energy our buildings would use over a 12-month calendar year.
