  1. P07421 - Sustainable Technology for the RIT Campus Lu Xu Jessie Gmeinder Chris Chaput Kevin Costantini Sam Eng Wojciech Mysliwiec Jeff Hoover Scott Rishell Bob Snow Eric Wong

  2. Feasibility Constraints Resources Economics Scope Technology Customer Needs Cost effective Decrease energy usage per FTE student by 10% by 2013 Improve RIT’s image as a green campus Provide experiential learning Environmentally friendly Overview

  3. Technology demonstration Photovoltaic (PV) Wind Solar Light Bio-diesel Technical report Energy Audit Water Cooling System Alternative Energy Sub Concepts

  4. Sub-Team Bob Snow Eric Wong Kevin Costantini Objective To design, build, and integrate a photovoltaic demonstrator onto the RIT campus To give students a chance to observe how this technology works and experiment with the system To explore what can be obtained from using this renewable energy source Concept Definition - PV

  5. Drawings

  6. Concept Selection Process • Developed 8 basic functions with concepts for each • Refined concepts and developed three sub-systems: • Type of Module (4 Concepts) • Mounting/Adjustment Setup (4 Concepts) • Display (2 Concepts) • Evaluated sub-systems/ developed system concepts • Initially evaluated concepts with weighted criteria • Initial Cost (35%) • Availability (20%) • Maximum Load (20%) • Efficiency (15%) • Ease of Install (10%)

  7. Rough Financial Requirements • PV MODULE: $800 • Battery: $300 • Inverter: $600 • Mount: $200 • Controller: $50 • Wiring, Grounding, & Disconnects: $300 • Miscellaneous: $250 • Total Cost: ~$2500

  8. Objective To produce 2nd generation stand alone roadway light To utilize hybrid technology power generation for best performance Sub-Team Jessie Gmeinder Sam Eng Wojciech Mysliwiec Concept Definition – Wind Solar Light

  9. Current Roadway light 30’ height 400w HPS bulb 0.6 ft-candles $3600 install ~$140/year to run 1st generation –recommendations Upgrade turbine Upgrade lighting Concept Generation – Wind Solar light

  10. Concept Selection Process • Chose LED light based on luminance and style • Developed 2 designs based on turbine changes • Vertical Axis (Savonius Style) • Horizontal Axis • Evaluated concepts with weighted criteria • Power Output (30%) • Cost Savings (25%) • Ease of Demo Manufacture (20%) • Durability (15%) • Aesthetics (10%)

  11. Rough Financial Requirements • LED: $725 • Turbine: $420-$875 • Solar panel: $0-$300 • Battery: $0-$75 • Pole: $700 -$1000 • Circuit: $100 • Total: ~$1945-$3075

  12. Objective To use RIT dining facilities existing waste vegetable oil (WVO) in producing usable biodiesel for campus vehicles To save $$ in amount of used diesel fuel Provide certain educational benefit for class learning from example Sub-Team Chris Chaput Scott Rishell Jeff Hoover Concept Definition – Biodiesel

  13. Refining Process Diagram pH Temp Methanol Reservoir Waste Vegetable Oil Reservoir Lye Reservoir Mixing Tank Glycerin Drain Operator Input Washing Tank Daq and Control Software Valve Control Bio-Diesel Storage Tank Pump

  14. Concept Selection Process • Marked out a general process flow • Determined potential usable amounts of WVO from sources • Considered placement of operations • Benchmarking of a commercial biodiesel processor • Weighted certain needs • Pump station included (15%) • Automated process (30%) • Make batches of 70+ gallons (20%) • Require low operator time (10%) • Robustness (5%) • Quality control (20%) • Estimated cost of materials for creating a single batch

  15. Rough Cost Analysis • A Biodiesel processor can pay for itself in little over 1/2 year in fuel savings • Serves as an example of alternative fuel in use • Product is cheaper when WVO is collected in greater quantities.

  16. Rough Financial Requirements • Major cost contributors: • Tanks: $350 • Tubing: $200 • Pumps: $200 • Immersion heater: $200 • Valves: $200 • Operation costs: ~$200/week • Initial Investment total: ~$2000

  17. Sub-Team Sam Eng Lu Xu Jessie Gmeinder Objective To save energy by maximizing efficiency of building systems Concept Definition –Energy Audit

  18. Energy Audit Process Flow Map

  19. Concept Selection Process • Developed 4 different audits • Initially evaluated concepts with weighted criteria • Audit ease of use (30%) • Feasibility (technical knowledge) (25%) • Length of audit/detail (20%) • Cost savings (15%) • Time to implement recommendations (10%)

  20. Benchmarking

  21. Objective To evaluate the implementation of a water cooling system that will: Meet campus cooling needs Save on energy consumption Utilize the Genesee River to provide a portion of cooling Reduce refrigerant usage Sub-Team Kevin Costantini Chris Chaput Scott Rishell Bob Snow Concept Definition – Water Cooling System

  22. Concept Selection Process • Developed 11 basic functions with concepts for each • Refined concepts and developed three sub-systems • Campus Distribution System (4 concepts) • Pumping/Cooling Station (3 concepts) • River Cooling Loop (4 concepts) • Evaluated sub-systems / developed 4 system concepts • Initially evaluated concepts with weighted criteria • Initial Cost (35%) • Operating Requirements (20%) • Efficiency (30%) • Land Displacement (15%)

  23. Drawing – Leading Concept

  24. Motivation Risks • Considerable investment • Implementation time • Construction requirements • Thermal discharge into Genesee River • River depth and temperature variations • Electricity savings • Improved cooling efficiency • Easier to maintain • Use of local energy as opposed to purchasing energy

  25. Benchmarking – Water Cooling

  26. The objective of the alternative energy group is to look into forms of alternative energy that can be used on or around campus and to illustrate the findings in a formal proposal Sub-Team Lu Xu Eric Wong Jeff Hoover Wojciech Mysliwiec Concept Definition – Alternative Energy

  27. Concept Selection • Wind energy, Electro kinetic energy, and methane were evaluated for this concept • Developed selection matrix with the following criteria • Cost (30%) • Environmentally Benign (20%) • Energy Production (15%) • Education (15%) • Image (10%) • Feasible within 5 years (5%) • Reduced Emissions (5%)

  28. Improve RIT’s financial position Reduce green house gas emissions Educational value Reduce 5-10% of RIT’s overall energy consumption Image acceptance Environmental impact (wetlands) Varying wind speeds Economic viability Location Motivation Risk

  29. Benchmarking – Wind Energy * Average wind speeds in Rochester, NY: 4.56 m/s

  30. Demo Cost Summary • Biodiesel system: ~$2000 • Wind-solar prototype: ~$3075 • PV demonstrator: ~$2500
