I’m not just talking about solar panels, geothermal heating pumps, wind turbines, and rainwater collection. Though I am an avid fan of earthships and other sustainable houses, I adore green rooftops. I just read an issue in this month’s issue of National Geographic about rooftops with gardens, lawns, flowers, grass, and plants. What do you think of that? I saw a picture of a building in England adorned with ivy. Would you support a municipal law requiring all flat rooftops to be green? Would you advocate a tax incentive to make other rooftops having vegetation as well?

And part of living in a free society is also respecting other people’s freedom and rights. That includes not polluting their soil, not depriving them of livable environments, and not compromising their quality of life.
I will, totally, support green codes. I do not however believe that mandatory green-roofs will ever get on a ballot or in the building codes. What we need (like you brought up) is a serious tax incentive/rebate plan for green-roofs for both Residential and Commercial. Wouldn’t it cool to water a green-roof from a rainwater collection system on the same building? I think we will see the day when all new buildings will be required to have a certain percentage of green integrations, technologic (panels water heaters, ventilation) and/or passive systems (like green-roofs, skylights, rain collectors). Let’s hope it’s soon. As for us, we will build a straw-bale home, off the grid,… with more dogs.
