2. Design Process Needs Assessment Conceptualization Production Preliminary Design Detailed Design Design a building that can utilize wind energy Using Google Sketch up and Solid Works we created a dorm that uses wind energy efficiently Patent Searches and Benchmarking Discusses ways to utilize wind turbines in buildings Make it aesthetically pleasing and cost efficient Researched types of turbines and costs of energy in dormitories . Measured wind speeds at different heights. Sketched many designs, and narrowed in on one.

7. Revised Problem statement • Energy efficiency has become of utmost importance in this “Green World”.  Dormitories, as seen in East Campus, are outdated, and use energy wastefully through old-fashioned heating systems, appliances, and building materials.  The addition of thousands of freshman only magnifies the effects these inefficient technologies have on the consumption of energy.  Although the consumers of energy feel few effects initially, in the long run there will be irreversible damage to the Earth.  Looking from the University’s perspective they would be attempting to decrease the amount of money spent on energy in attempts to put it towards other educational resources.  In general, making buildings which are energy efficient will save money, energy, and the Earth.  • Customer: Penn State University

10. Concepts • Building ~Have an architecturally pleasing building where the turbines do not look like they were simply bolted on afterwards. ~Chose a building that uses large amounts of energy, so it would benefit from the wind energy system • Horizontal vs. Vertical Turbine ~Incorporate both into the system in order to capture and store the most wind • Turbine Material ~Lightweight ~Durable ~Low Cost

11. Pugh Charts and Concept Selection How to Gather Wind We chose concept 4, four dorms in a square with tunnels in between, because it consistently outranked all of the others in this chart as well as in all other iterations.

12. Tunnel Material We chose concept 4, the one way mirror glass for our tunnel. It outranked aluminum and fiber glass, and ranked the same as steel. This was the same for all other iterations as well, and we felt the one way glass was a better fit.

13. Turbine Material The carbon fiber and fiber glass outranked the aluminum and steel, thus we chose to use carbon fiber for the vertical turbine and fiber glass for the horizontal ones. Turbine Location Having the turbines on the outside of the building was ranked as the best choice. We chose to have one large vertical turbine in the center of the four dorms and nine horizontal turbines per side (forty-eight total) because we felt this would produce the most energy.

14. Final design • 4 dorm buildings (here in State College) in a square with tunnels (made of one way mirror glass) in between each building. • 48 smaller horizontal turbines: 12 on each of the four sides, with 4 rows of 3 held up by horizontal bars. These turbines will be made out of fiberglass, and 500 W each. • 1 large vertical turbine in the center of the 4 dorms. It will be 5000 W and made out of carbon fiber.

20. Bill of materials Engineering Analysis: We feel the total cost is on par with typical costs of building an integrated wind system. The cost may vary do to differences in labor cost.

23. Calculation of energy • The total maximum energy produced by our turbines is 942,179.75 kWh/yr (223,181.03 kwh/yr by the VAWT turbine and 14979.14 kwh/yr by the HAWT turbines). • The estimated energy consumed by the four dorm buildings per year is 2,100,000 kWh. • This leaves 1,157,820.25 kWh of energy still being used per year.

24. Return on investment • The estimated costs of powering the four buildings without win energy assistance is $20,055,000 per year. • The estimated cost to power the buildings with the energy assistance is $11,057,183.39 a year saving the university $8,997,816.61 per year. • Thus, our integrated wind energy system will turn out to be a good return on investment.

25. FinalRemarks • By hiding the large turbine in the middle of the four dorms and having rows of smaller turbines in between the dorms, the buildings are still architecturally pleasing. • By choosing to have the turbines made out of fiberglass and carbon fiber, the goal of light weight, durable, and relatively low cost turbines was achieved. • By incorporating both HAWT and VAWT turbines as well as tunnels, the maximum amount of wind will be gathered.

26. Final Remarks • Overall, we feel we were able to design a sufficient integrated wind system that the consumer would be pleased with.
