1 Hillel House Project Review 2/27/09 Boiler Green Initiative

2 Introduction  Matt Leon – Senior, OLS (Project Leader)  Rachel Machbitz – Freshman, Engineering (Project Liaison)  Emily Pohlman - Senior, Environmental Science  Jessica Zuponcic - Freshman, Engineering Hillel House Boiler Green Initiative

3 Community Need  Relevance to the project partner What is the need that is being addressed?  Hillel House currently uses many of the same structures and appliances that were established with the house’s initial construction in 1959 and are in need of updating.  The building is wasting energy through excessively high heating and cooling bills. Hillel House Boiler Green Initiative

4 Community Need  Initial contact was made with the organization for the analysis of potentially establishing a green roof on the building.  Reducing building energy consumption will allow more funds to be directed to the students in the organization and improve the building. Hillel House Boiler Green Initiative

5 Goals of the Project  The BGI team will create a strategic plan to maximize energy savings with minimal capital input and implement small scale repairs and additions.  Our team will not be able to install large scale projects such as window replacement, electrical rewiring, or heating and cooling system changes. Hillel House Boiler Green Initiative

6 Goals of the Project  What is the success criteria? The success of this project will come from reducing energy costs for Hillel House at a rate that will justify the initial investment. Hillel House Boiler Green Initiative

11 Winterization  Insulation Keeps energy from escaping from the building and into the atmosphere, which keeps cost down.  Wrap Windows Keeps energy form escaping. Similar to insulation.  Replacing Broken Panes Replacing these panes will directly affect energy loss because we are fixing a hole in the wall. Boiler Green Initiative

12 Winterization Solutions  Insulation Caulking around windows, ceiling, and outlets  Wrapping Windows Clear wrap around all windows to help insulate  Replacing Broken Panes Taking out broken pane and replacing it. Hillel House Boiler Green Initiative

Rain Garden: Overview  A shallow constructed depression that is planted with deep-rooted native plants & grasses.  Easiest, most cost effective, and aesthetically pleasing thing that can be done to reduce the contribution to storm water pollution.  Reduces the need for an irrigation system.  Aesthetically pleasing while fixing the current walkway. 13 Boiler Green Initiative

Storage Calculations 14 Definite Integral Calculation-- Depth of reservoir: 1feet 11 2/3 inches Diameter of reservoir: 10feet 2 inches We are going to capture 600 gallons of rain which is 92% per rain event
