4. City of Choice: Cleveland, OH

5. Why Cleveland? Promising potential Ohio Wind Power Conference Nov. 2004 U.S. Sen. Sherrod Brown’s new legislation that would build a green manufacturing base in Ohio “Silicon Valley for Wind Power”

6. Average Wind Power

7. Customer Needs Analysis Kohl’s Department Stores -Uninterested Other small businesses concerned with up front costs Average MARR(minimum acceptable rate of return) of 12% As a result, we decided on a new design rather than a retrofit.

8. Design Matrix Generated by Customer Analysis Needs Metric MW Hr Economics Dollars Pride Stability Decibel Safety codes 1 The wind turbine can generate 15% of the building’s energy 2 The wind turbine has a payback period of less than 10 years 3The wind turbine is ascetically pleasing 4The wind turbine has a low initial cost 5The wind turbine is durable 6The wind turbine operates silently 7The wind turbine requires little maintence 8 The windturbine runs with winds as small as 5mph 9 The windturbine meets all safety requirements/regulations

9. Economic Analysis - Turbine Peak power of turbine is 1 MW – 1 MW x 30% capacity factor = 300 kW – 300 kW x (365 x 24 hrs) = 2,628,000 kW-hr per yr Estimated cost of a turbine + generator – Turbine = $250,000 – Generator = $500,000 Cost of maintenance = $13,140

10. Economic Analysis – Turbine, Cont Annual Worth = P(A/P, I, N) + A + G(A/G, i, N) + S(A/F, i, N) Offshore Turbine: -3,450,000(A/P, 12%, 25yrs) + (236,520 – 26,280) + 0 + 0 -3,450,000(0.1275) + 210,240 = -$229,635 Innovation Tower: -3,000,000(A/P, 12%, 75yrs) + (940,080 – 52,560) + 0 + 0 -3,000,000(0.1200) + 895,520 = $535,520

11. Economic Analysis – Turbine, Cont Net Present Value = A(P/A, i, N) Offshore Turbine: -229,635(P/A, 12%, 25yrs) -229,635(7.8431) = -$1,801,050 Innovation Tower: 535,520(P/A, 12%, 75yrs) 535,520(8.3316) = $4,461,738

12. Economic Analysis - Building Compared our design to the proposed Dynamic Tower in Dubai – The structure design and dimensions are similar – Estimated cost = $700 million This estimated cost is low compared to other skyscrapers – Easy assembly around main concrete core Building will use approx. 14.18 MW-hrs

13. ROI and Pay-off period for Turbines $750,000 (cost of turbine/generator) x 4 = $3 million (total cost of turbines) Estimated Yearly Revenue – 2,628,000 kW-hr x 4 = 10,512,000 kW-hr – 10,512,000 kW-hr x $0.09 per kW-hr = $946,080 – $946,080 - $13,140(maintenance cost) = $932,940 ROI = $932,940/$3 million = 31.1% ROI Payback = $3 million/$932,940 = 3.17 yrs

14. Initial Design Concept Horizontal wind turbines sandwiched between building floors Easily expandable design, can be used for buildings of all height Since the turbines are the same for all floors, this design has little unique parts, making it easier to manufacture

15. Initial Design, cont. Water tower energy storage concept Hydraulics system to move water tower to counter wind oscillations Fan shroud to improve efficiency Fan shroud controlled by pressure sensors Magnetic tracks for fan blades to reduce friction

16. Electrical and Structural Systems \Magnetic track connection between shaft and blades Central shaft for structural support. Also contains elevators, stairs, electrical wiring, and plumbing Magnetic coil around central shaft for power generation Curved blades for maximum efficiency
