University of Waterloo Presentation (2009)

  1. 1. Team Members: Rob Enouy Andrea Murphy Adrienne Nelson Tim Pasche Chris Rea Ankit Sharma Neal Tanaka Faculty Supervisor: Dr. Michael Fowler 1
  2. 2. Introduction  To design a student centre for Farmingdale Campus of SUNY  Goal was to be as energy efficient as possible  Powered by Renewable energy sources  Budget of $28MM  45,000 square feet 2
  3. 3. Overview  Hydrogen Systems  Biomass System  Photovoltaic Cells  Wind Turbine  Geothermal 3
  4. 4. 4 Hydrogen Process Diagram SOLAR Wind Stirling Engine (Bio Gas) GRID SUFFICIENT POWER Scenarios: INSUFFICIENT POWER ELECTROLYSER EXCESS ELECTRICITY ? CENTER (LOAD) YES NO H2 COMPRESSION H2 STORAGE PEMFC
  5. 5. Design Intent Second Floor Plan Ground Floor PlanBasement PlanSite Aerial Perspective Main Entrance
  6. 6. Environmental Design• Site Considerations • Solar Orientation • Maintaining Open Space • Water Use Reduction • Recycled or Locally Sourced Building Materials • Providing for Interior Air Quality • Constructability • Power Consumption vs. Generation
  7. 7. Geothermal Energy 7  Provides clean renewable energy  Proves a steady and reliable source of energy 24 hours a day, everyday  EPA has identified over 750,000 geothermal systems in USA
  8. 8. Geothermal Energy - Design  Can provide 70% of max heating load (75kW)  Supplemental heat supplied by high efficiency furnace  Closed loop system with 5 heat pumps (15 kW each)  Vertical arrangement, drilling depth – 30 m  Combined geothermal system with reinforced insulation – increasing our savings  Government grant available - up to 10% of total cost for new geothermal installations 8
  9. 9. Solar Power Total active area installed: 2,185 m2 kWpeak installed: 219.9 kW Total installed cost of solar modules: $1,475,394.80 Angle of solar cells to horizon: ~41°
  10. 10. Wind Power Selected windmill model: WTIC 31-20 Total number of windmills installed: 10 Total installed cost of windmills: $339,000
  11. 11. Biogas Generation  Releases CO2 but considered neutral  Reduces landfill tipping fees  Calculations based on industrial case studies  30 kW produced from 430 kg/day
  12. 12. Stirling Engine 12 http://www.animatedengines.com/vstirling.shtml  Advantages  Flexible in terms of fuel  Waste heat recycled  Less maintenance required  Relatively quiet  Disadvantages  Longer start-up time  Higher capital cost
