1 Hillel House Project Review 4/3/09 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 1950 and are in need of updating.  Our goal is to reduce electricity consumption by 15% and gas consumption by 20-30% 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. We don’t want to spend more than $4000 on the rain garden. Hillel House Boiler Green Initiative

10 Winterization  Insulation Keeps energy from escaping from the building and into the atmosphere, which keeps cost down.  Covering Windows with Plastic Keeps energy from 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

15 Windows: Data  Best Window and Door had a Lower U-Factor (.28 versus.31 for Bee Window)  Similar SHGC (Solar Heat Gain Coefficient)  Number of Windows vs. Price Bee Window: 71 Windows for $44, Best Window and Door: 82 Windows for $46, Best Window and Door has Lower Cost per Window ($564.86/Window) Boiler Green Initiative

16 Solar: Overview  Goals of Solar Energy Reduce electricity use from grid Creative use of passive solar to reduce heating/cooling needs Extend the roof overhang on the building in order to block sun in summer Hillel House Boiler Green Initiative

17 Solar: Proposed Solutions  Passive solar Use natural lighting to reduce interior lighting needs Can be utilized while minimizing window surface area during replacement Hillel House Boiler Green Initiative

Need for Rain Garden  Cuts down on water consumption  Reuse of rain water  Aesthetically appealing with the plants  Learning tool about wetlands for the community and Purdue by making a Rain Garden brochure 18

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.  Eliminates the need for an irrigation system.  Provides the opportunity to fix the current walkway. 19 Boiler Green Initiative
