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

4. Goals of the Project  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 4 Hillel House

5. 5 Boiler Green Initiative Practical Not Practical Possible RequirementsSolar Water heating Insulation of Pipes Solar Electricity Wind Turbines Price/Cost$$ $5000 with federal incentive Roughly $2.65/6’ of insulation About $20000 + possible incentives $6890+ shipping and installation Compatible with Indiana weather Requires plenty of sunlight Pipes are indoors, inside of building Requires a lot of sun; south-facing windows are desirable Requires wind to function Difficulty of Installation Should be installed professiona lly Easy to install Can either be installed professionally or by home owner Not enough information available Aesthetically pleasing Mostly metal and piping, and two panels Not visibleComposed of solar panels 18ft tall, made of metal, large cylindrical figure Feasibility Chart for Alternative Energy

6. 6 Design Criteria  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 Hillel House

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

8. 8 Boiler Green Initiative Input: Rain Intensity http://www.in.gov/dnr/water/4897.htm Figure : Rain Intensity for Lafayette, IN for T-Year Events – The longer the storm the greater rainfall depth for T-Year events. Using this intensity, input ≈ ft 3 /hr

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

11. 11 Discharge Calculations  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 Boiler Green Initiative Team Name Q = VA 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)

13. 13 Rain Barrel  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 Hillel House
