  5. Revised Problem Statement • Our objective is to design a wind energy system on a building of our choice. The building must be visually pleasing, yet still be effective enough to use wind as a major supplier of energy. Our chosen building, a 150,000m2mall outside of Boston, Massachusetts, has to incorporate current wind integration technology into its design. The wind energy must be cost efficient (ultimately save the mall money) and it must be in a geographical location that has a high enough average wind speed to make wind energy a viable power source. Our target population is the owners of the mall.

  6. Concept Generation Central Tower Design: This design consists of a tower in the middle of the mall which has the wind turbines in it, and a turbine at the top of the tower. There are 4 tunnels from each side of the mall which will funnel the wind into the vertical tunnel in which the turbines were located.

  7. FourCorner Design: The Four Corner Design has four wind turbines, one at each corner. The mall would have cut-outs at each corner for the turbines to fit in. The turbines would only be completely visible if you’re in front of them, and would be somewhat aesthetically pleasing due to the symmetry of the location of the turbines.

  8. One Big Turbine Design: The One Big Turbine Design has one turbine on the roof of the mall. The turbine has a diameter of 110 meters. This design was a preliminary idea that was ultimately transformed into our Central Tower Design.

  9. Many Turbine Design: The Many Turbine Design consists of about 30-50 small turbines which are lined up on top of the roof.

  10. Morphological Chart

  11. Pugh Charts Pugh chart for Types of Turbines So, the Vertical, Horizontal, and Helical turbines are all ranked equally We also created Pugh charts for: -The Location/Layout of the Turbine(s) -Highest Ranked: Central Tower Design -Materials Selection -Highest Ranked: Resin with Carbon Fiber

  12. Bill of Materials • 30 Horizontal Wind Turbines (10m diameter) • 28 GorlovHelical Turbines (2m diameter) • 1 Gorlov Helical Turbine (10m diameter) • 5 Generator Systems (1 for Central Chamber, 4 for Corner of Mall Gorlov Helical Systems) • 6.33m3 Stainless Steel (Cylinder: .25m diameter, 129m height…45m height for central chamber, 4x21m height for the corner helical system)

  13. Final Design Details • Total of 59 Turbines • Wind is funneled through a decreasing area from the outer wall into the center of the building, where it is directed upwards into a central tower • Wind in the tower turns the horizontal turbines and ultimately the helical on top (external wind also powers the top helical) • Water drainage system at the base of the central tower • External wind powers the four corner helical columns • Holes at the top of the column in order to let extra external wind into the tower

  14. Engineering Analysis: Mall • To construct a mall of approximately 150,000 m2, the cost of construction (including labor, materials, etc.) is about $400 million • Our mall is approximately 220m x 220m x 21m • It consists of three floors • The four quadrants are connected at the very bottom and very top the entire way around (this is how customers would navigate between quadrants)

  15. Engineering Analysis: Cost of Turbines • Horizontal Wind Turbines (10m diameter): $55,000 • GorlovHelical Turbines (2m diameter): $15,000 • GorlovHelical Turbine (10m diameter): $60,000 • Generator Systems (1 for Central Chamber, 4 for Corner of Mall Helicals): Price Included in Turbine Cost • 6.33m3 Stainless Steel (Cylinder: .25m diameter, 129m height…45m height for central chamber, 4x21m height for the corner helical system): $5,064 • Labor: 100 workers, 8hr/day, $18/hr, 30 days: $500,000 • TOTAL: 30($55,000) + 28($15,000) + $60,000 + $5,064 + $500,000 = $2.64 million

  16. Conclusion • With a cost to build of $2.64 million and an annual energy savings of $3.92 million, building the system will pay off in approximately 8 months, 2.5 days • We strongly feel that we met all of our customer needs due to our innovative design, effective choice of material, large power output of the system, and the location of the turbines with respect to safety
