Boiler Green Initiative (BGI)Design Review December 11, 2009 Neil Armstrong Hall of Engineering Boiler Green Initiative
Agenda Hillel House • Overview of team • Hillel House • Wind Turbine • Bio Energy • Questions Boiler Green Initiative
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
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
Feasibility Chart for Alternative Energy Possible Not Practical Practical Boiler Green Initiative
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
Water Balance Calculations • Basic mass balance calculation • Retained water = Inputs – Outputs Input: Outputs: garden charging rate Top view, rain garden catchment Boiler Green Initiative
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
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
Water Calculation Results Team Name For a 2 year rain event, runoff is capture d for the following storm duration: Boiler Green Initiative
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

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
