Slide 4
City of Choice: Cleveland, OH
Slide 5
Why Cleveland? Promising potential Ohio Wind Power Conference
Nov. 2004 U.S. Sen. Sherrod Browns new legislation that would build
a green manufacturing base in Ohio Silicon Valley for Wind
Power
Slide 6
Average Wind Power
Slide 7
Customer Needs Analysis Kohls 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.
Slide 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 buildings 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
Slide 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
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
Slide 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
Slide 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
Slide 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
Slide 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
Slide 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
Slide 17
Artist Rendition of Initial Design
Slide 18
Final Design, Central Shaft Generator coils and magnets
Elevators and staircases Central lounge All the other plumbing and
electrical equipment
Slide 19
Final Design, Lobby and Recycled Water System Water Feature
