Overview Concept & Design Approach Background Vertical Axis Wind Turbines Application Prototype Cost Analysis Return on Investment Summery & Conclusion
Concept & Design Approach Objective:
Design an aesthetically appealing commercial building with integrated wind turbines to generate clean energy.
Design Approach: Integrated Vertical Axis
Wind Turbines along the corners of the building
Unified building-top turbine system in x shaped array
Background How wind is generated
Temperature differences Cold air in cities vs. warm
air in surrounding area Current Applications
Horizontal Axis Wind Turbines
Vertical Axis Wind Turbines Main concept of the
building design based off of the usage of VAWT
VAWT allow for more integrated wind energy generation
Better integrated wind energy systems
More efficient in turbulent wind conditions Like around buildings

Return Investment
Researched/Assumed Facts:-Average wind speed of 10mph for 12 hours per day-Average cost of electricity: 12.73 cents per kWh-Life span of Turbine is 30 years-Air density = 1.23 kg/m^3-Betz Limit = 59.26%
Calculations:
Maximum Available Power from wind = (.5)*(air density)*(surface area of turbine)*(wind velocity)^3*(Betz Limit)
Maximum Available Power from wind = 2185watts or 2.2kW
Power Generation
Profit of Power Generated = (Maximum Available Power from wind)*(hours per day)*(days per year)*(current market price of electricity)
Profit of Power Generated = $1226.66/yr
Breakeven Time
Time to Breakeven = (cost of turbine)/(profit of power Generated)
Time to Breakeven = 12.27 years
Return of Investment
ROI = [(gain from investment) - (cost of investment)] / (cost of investment) *100
ROI = 144% over 30 years
