When designing new government buildings, make the roof out of solar panels with no underlying roof. Doubling the roofing doubles the materials and labor costs while adding unnecessary weight. If the roof is an integrated solar panel, you would not need to have a roof underneath. the solar panels could either be for electricity or for hot water. Additionally, designing the solar collector to also manage rainwater into cisterns, rain gardens, or other beneficial uses would be a big plus.
