  1. Team 5 – Puerto Rico Zach Balton Bianca Marie Lopez de Victoria James Ball Evan Niemann

  2. What is our design goal? Seamlessly integrating a modern design/technology, typically seen in rural areas, into an urban environment. + = ??

  3. Early Concepts Sketches The “Diner” Look Either the hanging, or resting design could have been used Design meant to remain small while catching more wind (multiple turbines)

  4. Refined “Diner” Design Integrated for Building Type Compares traditional open face turbine to confined design

  5. Building Top Ideas Rather than using only one edge of the roof, takes advantage of entire space “Pyramid” Design

  6. “Mayan” Design Modification of original Pyramid Design. Implements flat roof rather than pitched.

  7. What are the needs? We chose our design based on a list of criteria the final design needed to meet.

  8. Designs Under Review The “Diner” Design (Resting) The “Diner” Design (Hanging)

  9. “Pyramid” Design “Mayan” Design “Mayan” Design has the highest results

  10. The “Mayan” Dimensions The example building for our design: The One World Trade Center

  11. Top and Frontal Dimensions The top of our example building has the projected dimensions of 145’ x 145’ (1) (1): Taken from http://www.glasssteelandstone.com/BuildingDetail/439.php

  12. Turbine Dimensions

  13. Outcome of design (Shown with antennae):

  16. Power Output of Final Design Optimal Wind Speeds for Turbine is 15 m/s Ideally, wind turbine of diameter 10.668 meters will have a power output of approximately 25 kW http://science.howstuffworks.com/wind-power4.htm

  17. Usable life of turbine ~ 20 years http://www.awea.org/faq/sagrillo/ms_oandm_0212.html

  18. total volume of installed material = 10(1102 + 802 + 502 + 302) = 219,000 ft3

  19. Net Value of Turbine (size) x (average price) = turbine price (25 kW) x ($1,000/kW) = $25,000 install price = $15,000 http://www.windpower.org/en/tour/econ/index.htm

  20. (length of steel framework) x (cost of steel) = cost of framework (15,000 ft) x ($2/ft) = $30,000 (length of steel framework) x (cost to install steel) = install cost (15,000 ft) x ($1.50/ft) = $22,500 (volume of brick) x (cost of brick) = cost of brick (200,000 ft3) x ($0.01/ft3) = $2,000 (volume of brick) x (cost to install brick) = install cost (200,000 ft3) x ($0.02/ft3) = $4,000 total value of structure = $58,500 http://www.get-a-quote.net/

  21. Initial Costs total materials cost = $57,000 total labor cost = $41,500 total install cost = $98,500

  22. (power produced) x (emissions prevented) x (price of carbon credit) = revenue (25 kW) x (0.520 tons/MWH) x ($10) = $130 monthly $1,560 annually http://www.ecobusinesslinks.com/carbon_offset_wind_credits_carbon_reduction.htm www.eia.doe.gov/pub/oiaf/1605/cdrom/pdf/e-supdoc.pdf

  23. (electricity price) x (power output) = savings ($0.10/kWh) x (25 kW) = $2.50 hourly $60 daily $21,900 annually http://www.eia.doe.gov/neic/brochure/electricity/electricity.html

  24. maintenance estimate maintenance costs = 1% of install cost ($98,500) x (1%) = $985 annually maintenance = $985 annually http://www.awea.org/faq/sagrillo/ms_oandm_0212.html

  25. net annual revenue = $22,475

  26. Economics $58,500 P= $98,500

  27. Economics ROI= Avg. Net Annual Income First Cost ROI= $23,460 / $98,500 = 0.2382 x 100 = 23.82% ROAI= Avg. Net Annual Income Avg. Book Value Avg. Book Value= First Cost + Salvage Value= $98,500 + $58,500 2 2 = $78,500 ROAI= $ 23,460 / $ 78,500 = 0.2989 X100 = 29.88%

  28. Economics Payback Period(2): -$98,500 + $23,460 = -$75,040 -$75,040 +$23,460 = -$51,580 -$51,580 + $23,460 = -$28,120 -$28,120 + $23,460 = -$4,660 -$4,660 + $23,460 = $18,800 Approximately 4.3 years

  29. Economics 10% Interest Rate Factor Net Present Value: $23,460  (PA, 10%, 20) = $23,460(8.5135) = $199,726.71 $985  (PA, 10%, 20) = $985(8.5135) = $8,385.79 NVP = -$98,500 + $199,726.71 + $8,385.79 = $109,612.47
