The roof is insulated to R-48 and the aboveground exterior walls are insulated to R-42. Approximately 77% of the roof is clad with solar panels, which help to cool the building by shading the roof. The chai achieves nearly zero net-energy use, due to high-energy efficiency and electrical production from the photovoltaic system. All heating systems are powered by electricity, not gas. The visible, above-ground portion of the building uses unfinished recycled-steel panels, which will eventually patina to blend in with the agricultural surroundings.
