  1. Boiler Green Initiative (BGI)Design Review December 11, 2009 Neil Armstrong Hall of Engineering Boiler Green Initiative

  2. Agenda Hillel House • Overview of team • Hillel House • Wind Turbine • Bio Energy • Questions Boiler Green Initiative

  3. Rachel Machbitz, Team Leader Bio Energy Hillel House Wind Turbine Sean Zimmerman, Project Leader Beth Doering, Project Leader Jared Freyer, Project Leader and Webmaster Scott Sylvester Isaac Payne Fahad Ahmad Yuanhua Cheng Bryson Maikranz Hannah Keller Anthony Christie Team Overview: Organization Hillel House Joseph Cox LexiStehr Amber Ramsey Liz Hoffa Katie Jones Boiler Green Initiative

  4. Goals of the Project Hillel House • Focuses this semester: • To prevent soil erosion • Make the property more aesthetically pleasing • Complete rain garden design • Secondary goals • Make the Hillel House more energy efficient • Determine alternative energy sources • Community education

  5. Feasibility Chart for Alternative Energy Possible Not Practical Practical Boiler Green Initiative

  6. Design Criteria Hillel House • Criteria • Must be at least 10 feet from building • Size should be 20-30% of roof drainage area (for sandy loam soil) • Garden should optimize backyard drainage • Must have outlet for overflow Boiler Green Initiative

  7. Water Balance Calculations • Basic mass balance calculation • Retained water = Inputs – Outputs Input: Outputs: garden charging rate Top view, rain garden catchment Boiler Green Initiative

  8. Input: Rain Intensity Using this intensity, input ≈ ft3/hr Figure : Rain Intensity for Lafayette, IN for T-Year Events – The longer the storm the greater rainfall depth for T-Year events. http://www.in.gov/dnr/water/4897.htm Boiler Green Initiative

  9. Output: Infiltration Rate • Soil Type: Carmi • Well drained, deep sand/gravel • Sandy loam surface texture • Infiltration test • Surface: 3.17 in/hr • Subsurface (9 in): 3.75 in/hr • Error • 3D movement • Time constraints Boiler Green Initiative

  10. Water Calculation Results Team Name For a 2 year rain event, runoff is capture d for the following storm duration: Boiler Green Initiative

  11. Discharge Calculations Team Name • Assumed laminar, incompressible fluid • Bernoulli’s Eqn. – used to calculate velocity in pipe • Manning’s Eqn.– used to calculate fluid velocity in open channel • Discharge Eqn. – used velocity to find discharge V = velocity in ft/s p = pressure (psf) g = force of gravity (ft/s^2) ρ = specific gravity z = elevation (ft) n = surface roughness coefficient R = hydraulic radius (ft) S = slope of energy line º slope of bed V = velocity (ft/sec) V = velocity (ft/s) A = area (ft^2) Q = VA Boiler Green Initiative

  13. Rain Barrel Hillel House • Why use a rain barrel? • Increase water holding capacity • Environmentally friendly way to use water – don’t need as much from tap • Water storage for use during dry periods during summer • 50 gal would provide .85 in, or 53.3% of available water to plants • 50 gal costs $0.15, however customer would like the barrel Boiler Green Initiative

  14. Rain Barrel Design Hillel House Drain pipe 4 in Slip cap Valve 50 Gal. Rain Barrel 4 in Trench 2 in www.plumbingstore.com/pvc.html www.alibaba.com/product/satmip-10832960-10638 Boiler Green Initiative

  15. Rain Barrel Decision Hillel House Emsco 60 Gal. Deluxe Rain Barrel with Downspout Diverter, Hunter Green $99.99 • Durable, UV-stable 25% recycled resin • Lid can be removed for dipping large watering can • Plastic, can drill holes into it Digital image.

  16. Flowers for Rain Garden Hillel House • Constraints: • Tolerant of partial shade • Moisture conditions • Not invasive • Non spreading http://www.critsite.com http://image24.webshots.com http://www.northcreeknurseries.com Beatles spring or vernal sedge Marsh Blazing star Turtlehead http://davesgarden.com/guides/pf/go/73540/ http://davesgarden.com/guides/pf/go/1014/ http://davesgarden.com/guides/pf/go/133012/ Yellow Columbine, Golden Columbine Celandine Poppy, Wood Poppy White water lily http://www.rockingham.k12.va.us/ Day Lily 16 Boiler Green Initiative
