Today the most interesting thing I learned was about the Living Pa. I had never heard of the living building challenge before. I thought that this was a really cool way to inspire people to not only incorporate sustainable initiatives, but really be innovative and go to the extremes of sustainability. It was interesting to learn that this company was started in Seattle and made me want to learn more about this program. Sustainable architecture is such an important part to creating sustainable cities, and yet it is relatively new. Not only does it create less waste and save energy, but it creates and spreads a sustainable mindset that will will help each person change their actions.
