  2. 2. What’s the Matter with Buildings?<br />According to the World Watch Institute, buildings account for one fourth of the world's wood harvest, two fifths of its material and energy usage, and one sixth of its fresh water usage.<br />
  3. 3. Natural Building<br />Doing more with less is the key to working with, and not against, the natural world that supports us.<br />

  43. 43. Rethinking the Material World<br />“Beat, heat and treat is a good methodology, and it built the country,” says Brandon Tinianov, chief technology officer of Serious Materials. <br />“But we have to approach it a little differently because our eyes are now open.”<br />Dwell 2008<br />
  44. 44. “So if you want to change something big, you have to change the material first.”<br />Material science is design at the molecular level. <br />How molecules are shaped, and how those shapes link together, determines the physical properties.<br />Ordered molecules, like diamonds, are harder and stiffer, while messy molecules can be pulled apart.<br />
  45. 45. Small changes, like turning iron into steel by adding carbon, have world-changing impact on what can be imagined, planned and built.<br />
  46. 46. Green plastics & Biomimicry<br />How does nature make things?<br />Plants make things out of CO2 and then assemble them into bark and leaves.<br />Replacing complex liquid carbon (petroleum) with strings of simple carbon oxides also requires less energy than standard polymer making.<br />It’s a low-temperature, low-pressure reaction.<br />Charles Hamilton, Novomer Inc.<br />
