A living building is like a flower, planted and rooted to its place. It collects its energy from the sun. It harvests its water from the rain. This building does not pollute. It engages actively with the environmental around it. And its beautiful and inspiring. This is natures blueprint for building a better world, says visionary architect Jason McLennan. He designed the Living Building Challenge 2.0 to raise the bar on green building: meet or exceed what nature provides. While the standards seem impossibly high, it may be simpler than we imagined.
