Leed Presentation Introduction on Fuel Cells

  1. 1. LEED and Alternative Energy STUDIO dnk was founded on the belief that there is a better way to build. It is a process that brings the Client, Architect, Engineers, and Contractor together in a collaborative environment that fulfills the Client's vision within budget, while respecting the environment .  
  2. 2. LEED NC 2009
  3. 3. LEED NC 2009
  4. 4. Energy and Atmosphere – Credit 1 <ul><li>Intent </li></ul><ul><li>To achieve increasing levels of energy performance beyond the prerequisite standard to reduce environmental and economic impacts associated with excessive energy use. </li></ul>Optimize Energy Performance
  5. 5. Energy and Atmosphere – Credit 2 <ul><li>Intent </li></ul><ul><li>To encourage and recognize increasing levels of on-site renewable energy self-supply to reduce environmental and economic impacts associated with fossil fuel energy use. </li></ul>On-site Renewable Energy
  6. 6. Smart grid
  7. 7. Building Integrated Solar Power
  8. 8. PV cell efficiency
  9. 9. Building Integrated Wind Power
  10. 10. Wind Power in the US
  11. 11. Fuel Cells
  12. 12. Where does H 2 comes from? steam reforming of natural gas - The fossil fuel that has the best hydrogen to carbon ratio is natural gas or methane(CH4 ) water based hydrogen production - nanostructured supported gold electrocatalysts photobiological – cyanobacteria achieve carbon monoxide to hydrogen conversion efficiencies of 100% biomass – hydrogen yields of 12% - 17% by weight of the dry biomass
