  2. Agenda • Overview of team • Pay-As-You-Throw • Hillel House Boiler Green Initiative

  3. Team Overview: BGI • The BGI team is involved with creating, designing, and implementing systems benefiting the local community and environment Boiler Green Initiative

  4. Team Leader: Ken Little Hillel House Pay-As-You-Throw Project Leader: Matt Leon Heather Carhart William Naville Caroline Early Nicole Samuelson Yitian Hu Team Overview: Organization Project Leader: Udit Pandey Ken Little Cassie Sands Bhakti Khandagale Allyssa Stoll Rachel Roberts Boiler Green Initiative

  5. Pay-As-You-Throw (PAYT)Project Review 11/14/08 ARMS 1098B Boiler Green Initiative

  6. Introduction PAYT • Heather Carhart – Senior in Quantitative Agricultural Economics • Caroline Early – Sophomore in Communications • YitianHu – Sophomore in Civil Engineering • BhaktiKhandagale – Freshmen in First Year Engineering • UditPandey – Sophomore in Mechanical Engineering • Rachel Roberts – Senior in Math Education and Natural Resources & Environmental Science http://www.epa.gov/osw/conserve/tools/payt/topics.htm Boiler Green Initiative

  7. What is Pay-As-You-Throw? • System where residents pay for Waste service based on trash thrown out or put at curbside • Residents only pay for what they use similar to utility system • Two Basic PAYT systems: Volume and Weight • Volume uses bags, tags, or stickers • Weight uses various can sizes per pound • More than 5,000 communities in the U.S. practice PAYT • Cities large and small, rural and urban http://www.epa.gov/osw/conserve/tools/payt/tools/index.htm http://www.epa.gov/osw/conserve/tools/payt/top20.htm Boiler Green Initiative

  8. Community Need PAYT • Our project partner: Rev. Peter Bunder • Investigate an alternative waste and recycling system for the city of West Lafayette • Benefits to Addressing Community Needs • Proposal and innovative ideas presented to Rev. Peter Bunder and West Lafayette Go Greener Commission • Equity in the community • Encourage recycling in the greater society Boiler Green Initiative

  9. Community Need PAYT • Relevance to the project partner • Design Question: Is a metered trash or Pay-As-You-Throw program feasible for the city of West Lafayette? • Reasoning: Avoid an increase in resident’s sanitation bill • Current system is a fixed rate for a variable amount of waste • Current system is not sustainable Boiler Green Initiative

  10. Goals of the project PAYT • Duration of Project: 12 months • Goals: Proposal for pilot program and PAYT program • Not currently addressed: Education and Implementation • Potentially addressed next semester http://www.epa.gov/osw/conserve/tools/payt/top7.htm • Overall Objectives: Case Studies in Bloomington, Indiana and Lansing, Michigan & Pilot Program in West Lafayette’s 2nd District Boiler Green Initiative

  11. Goals of the Project PAYT • What is the success criterion? • Presentation of concise and current information concerning the PAYT program, endorse a specific rate structure design • What are the deliverables? • A proposal for best method to implement a PAYT program for the city of West Lafayette. Boiler Green Initiative

  12. Background Information Boiler Green Initiative

  13. Background Research PAYT • Research Case Studies and current waste disposal system of West Lafayette • Additional information that could be utilized. • We could also use first hand knowledge and reviews of PAYT programs in Indiana and grants that will financially aid the implementation and sustenance of the program. Boiler Green Initiative

  14. Benefits to PAYT program • Environmental Sustainability: Effectively promotes waste reduction • Economic Stability: Stable revenue covers cost of services • Equity: Economically fair delivery of services PAYT offers “a direct economic payback to the people” —San Jose elected official http://www.epa.gov/osw/conserve/tools/payt/tools/index.htm Boiler Green Initiative

  15. Benefits to a PAYT program • Duke University National Study • 14 to 27% average waste reduction • 32 to 59% increase in recycling Source: http://www.epa.gov/epawaste/conserve/tools/payt/tools/sld_show.htm • Examples of U.S. Cities Saving • Wilmington, NC (population 75,000) $400,000 per year • Littleton, NH(population: 5,800) $40,000 in extra fundswith PAYT • Gainesville, FL (population: 96,000) $186,200 savingsSan Jose, CA(population: 850,000) reduced cost by $4 million annually http://www.epa.gov/osw/conserve/tools/payt/tools/index.htm Boiler Green Initiative

  16. Barriers to a PAYT program • Potential for illegal dumping • Potential for uneven cash flow due to variable rates • An increase in administrative costs • Identifying trash to residents in multiple unit housing Boiler Green Initiative

  17. Bloomington Case Study & Current West Lafayette Waste System Boiler Green Initiative

  18. Figure 1 Bloomington, Indiana Two Yellow sticker ($4) per bin FREE One green sticker ($1) per bin Two Yellow sticker ($4) per bin One Yellow sticker ($2) per bin

  19. Bloomington: Overview of Regular Services PAYT • Number of households served: 15,100 • Tons of trash decreased from 2004 – 2007 by approximately 800 tons which in cost is $30 thousand in ATF • In 2007, next revenue from tags was approximately $960,400 Boiler Green Initiative

  20. Lansing, Michigan: Overview of Services • Proportional Rate System utilizing both Bags for trash and stickers for bulk items. • Blue Billy Trash Carts System • 32 gallon = $38.00 per 3 months • 65 gallon = $48.00 per 3 months • 95 gallon = $49.00 per 3 months (includes 3 extra 30 gallon bags on side) • $50 annual fee that covers recycling costs • Purchase a package of 5 blue bags for $8.75 at convenience stores and local grocery stores as needed. • Yard waste is collected between April and November. • Large Items over 30 pounds and/or longer than 4 feet in length, such as furniture must be tagged with a bulk collection sticker ($33.00 per sticker). • Restrictions: nothing over 30 pounds and/or 4 feet in length without bulk item sticker Boiler Green Initiative

  24. Budget & Future Semester Plans Boiler Green Initiative

  25. Preliminary Budget PAYT Boiler Green Initiative

  26. Discussion of Future Plans/Current Decisions PAYT • Currently, our team has begun the Rate Structure Design in which we have many decisions and aspects to consider. • Following a decision concerning billing process, rate structure design we will complete a proposal suggesting a method to implement a Pay-As-You-Throw program in West Lafayette. http://www.epa.gov/osw/conserve/tools/payt/top15.htm Boiler Green Initiative

  27. Rate Structure Decisions: • Proportional • Variable • Two-tiered/ Multi-tiered http://www.epa.gov/epawaste/conserve/tools/payt/tools/sld_show.htm Boiler Green Initiative

  28. Rate Structure Design • Program goals • Waste Prevention • Greater Equity (greater level of fairness) • Extended landfill capacity (ATF) • Revenue Stability • Addressing Barriers • Well-designed rate structures can help communities control illegal diversion and cooperation between departments and collaborative community efforts can prevent enforcement difficulties http://www.epa.gov/osw/conserve/tools/payt/tools/official.htm • Pricing System: Proportional, Variable Rate, Multi-tier • Analysis: estimate price based on budget or perform advanced rate setting analysis for projected year • Keys to Success: Complementary Programs & Education Boiler Green Initiative

  29. Rate Structure Design • Proportional Pricing System: Each household spends $10 per month Creating a $558,000 revenue generated from the sale of trash tags, which is much more than generated from $9 fixed rate without including increase in recycling revenue generated • Assumptions: • Current W. Lafayette Trash Trends • PAYT National Trends • Proportional Estimate 35 gallons of trash weighs no more than 40 pounds • Estimated Need per Household is 5 tags/bags (35 gal) per month Boiler Green Initiative

  31. Hillel HouseProject Review 11/14/08 Boiler Green Initiative

  32. Introduction Hillel House • Matt Leon (Project Leader, Management, Senior) • Kenneth Little (Engineering, Senior) • William Naville (Engineering, Freshman) • Nicole Samuelson (Engineering, Freshman) • Cassie Sands (Engineering, Freshman) • Allyssa Stoll (Engineering, Freshman) Boiler Green Initiative

  33. Community Need Hillel House • 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. Boiler Green Initiative

  34. Community Need Hillel House • 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. Boiler Green Initiative

  35. Goals of the Project Hillel House • 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. Boiler Green Initiative

  36. Goals of the Project Hillel House • 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. Boiler Green Initiative

  37. Solution Feasibility Chart Hillel House Feasible Possible Not Feasible Boiler Green Initiative

  38. Solar: Overview Hillel House • Goals of Solar Energy • Reduce electricity use from grid • Creative use of passive solar to reduce heating/cooling needs Boiler Green Initiative

  39. Solar: Proposed Solutions Hillel House • Passive solar • Use natural lighting to reduce interior lighting needs • Can be utilized while minimizing window surface area during replacement www.eere.energy.gov Boiler Green Initiative

  40. Solar: Proposed Solutions Hillel House • Solar water heating • Reduce heating costs for hot water production • Minimal hot water consumption makes this option less necessary www.eere.energy.gov Boiler Green Initiative

  41. Solar: Proposed Solutions Hillel House • Photovoltaic cells • Reduce the use of electricity from grid (Duke Energy) • Climate limits viability in Indiana • $23,000: 3.87 kW system would return $345.73/year in electricity costs (http://rredc.nrel.gov/solar/codes_algs/PVWATTS/version1/US) • 66.5 year payback www.solarpanelstore.com Boiler Green Initiative

  42. Green Roofs: Overview Insert Project Name Here • A building roof covered partially or fully by vegetation. • Provides insulation for the house which would increase energy efficiency. • Save cooling costs up to 75% in the spring and summer. • Reduces water runoff, can retain as much as 60 percent of all rainwater. Boiler Green Initiative

  43. Green Roofs: Partial extensive Insert Project Name Here • Vegetation covers only specific sections of the house. • Cheaper than full roof. • However, costs more per square foot. • Can be placed in strategic locations. Boiler Green Initiative

  44. Green Roofs: Full extensive • The roof size of the Hillel House is 5850 sq ft. • It costs about $13.80 per square foot to install a green roof. Total cost of $80,671 • At the current electricity prices, they would save about $420 per year with a green roof. • 192 year payback Boiler Green Initiative

  45. Green Roofs: Limitations Insert Project Name Here • It is much more cost effective on a larger scale than the Hillel House. • May not be cost effective enough to implement on the Hillel House. • The roof needs to be structurally sound. The condition of the Hillel House roof may not be adequate and full saturated weight is between 20-50 lbs/sq.ft. • Environmental benefits far outweigh financial benefits Boiler Green Initiative

  46. Winterization: Overview Insert Project Name Here • Winterization • Insulation • Wrap Windows • Replace Window Panes • Replace Window Caulking Boiler Green Initiative

  47. Infrared Heat Loss Images

  48. 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

  49. Winterization Solutions Insert Project Name Here • 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. Boiler Green Initiative

  50. Geothermal: Overview • Geothermal heating/cooling systems use a heat pump and a system of underground exchangers to heat and cool a building more efficiently than conventional methods. Boiler Green Initiative
