Seamlessly integrating a modern design/technology, typically seen in rural areas, into an urban environment. + = ??
Either the hanging, or resting design could have been used Design meant to remain small while catching more wind (multiple turbines) The “Diner” Look
Compares traditional open face turbine to confined design Refined “Diner” Design Integrated for Building Type
“Pyramid” Design Building Top Ideas Rather than using only one edge of the roof, takes advantage of entire space
“Mayan” Design Modification of original Pyramid Design. Implements flat roof rather than pitched.
We chose our design based on a list of criteria the final design needed to meet. MetricRating (1-10) WeightTotal Ease of Integrationx2 Safe for chosen environment x2 Efficiencyx2 Aesthetic Integrationx1 Ease of Maintenancex1 Building Cost (Low)x1 Total:

The example building for our design: The One World Trade Center
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 Top and Frontal Dimensions

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.c om/wind-power4.htm Rotor Size and Maximum Power Output Rotor Diameter (meters)Power Output (kW) 1025 17100 27225 33300 40500 44600 48750 541000 641500 722000 802500 Sources: Danish Wind Industry Association, American Wind Energy Association
~ 20 years http://www.awea.org/faq/sagrillo/ms_oandm_0212.html Usable life of turbine
total volume of installed material = 10(110 2 + 80 2 + 50 2 + 30 2 ) = 219,000 ft 3
(size) x (average price) = turbine price (25 kW) x ($1,000/kW) = $25,000 http://www.windpower.org/en /tour/econ/index.htm install price = $15,000 Net Value of Turbine
(length of steel framework) x (cost of steel) = cost of framework (15,000 ft) x ($2/ft) = $30,000 (volume of brick) x (cost of brick) = cost of brick (200,000 ft 3 ) x ($0.01/ft 3 ) = $2,000 http://www.get-a- quote.net/ (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 to install brick) = install cost (200,000 ft 3 ) x ($0.02/ft 3 ) = $4,000 total value of structure = $58,500
total materials cost = $57,000 total labor cost = $41,500 total install cost = $98,500 Initial Costs
(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 www.eia.doe.gov/pub/oiaf/1605/cdrom/pdf/e-supdoc.pdf http://www.ecobusinesslinks.com/carbon_offset_wind_credits_carbon_re duction.htm
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%
