Everyone pays attention to cars, power plants, etc., but few are talking about our largest environmental impact: buildings. Buildings use 76% of our total electricity vs. transportation which uses 1%. Buildings are the largest energy consumer of any type and have the highest CO2 emissions. LEED standards are moving us in the right direction, but they are still not a Net Zero impact. What's more, we could make buildings that actually *restore* the environment. In my talk I'll share the evolution of building sustainability, our current environmental impact, and share what is possible for the future.
