  1. ASM: Building Integrated Wind Turbines April 24, 2008 AV’s Architectural Wind™ Development Paul M. Glenney

  2. GOSSAMER ALBATROSS AeroVironment – Icons of Cleannovation GM IMPACT GLOBAL OBSERVER GM SUNRAYCER HELIOS Doing more with much less… AeroVironment Inc.

  3. Wave Power: NAF Utility Scale Applications Two Prototypes Deployed Off Catalina Island Current/Tidal Power: Eelgrass Premium Power for Instruments on the Seabed Floor Example: Seismic Monitoring for Offshore Oil & Gas Mapping RE Powered Devices: Mola Solar Powered “Sea Turtle” Applications Include Monitoring: Eddy Currents for Oil & Gas Platforms Algae Bloom for Commercial Fishing Coral Reef Health Port Security Recent AV Developments in Marine Energy AeroVironment Inc.

  4. "Energy is the single most important problem facing humanity today. We must find an alternative to oil. We need to somehow provide clean, abundant, low-cost energy throughout the world to the 6 billion people that live on the planet today, and the 10+ billion that are expected by the middle of this century. The cheaper, cleaner, and more universally available this new energy technology is, the better we will be able to avoid human suffering, and the major upheavals of war and terrorism." • Richard E. Smalley, Nobel Laureate AeroVironment Inc.

  5. Coal: 209 years & counting… • Nearly 50% of US electricity is generated from coal • LADWP’s ratio is very similar • Coal plants release sixty varieties of hazardous air pollutants, among them lead, chromium, arsenic and mercury • Clean coal: ”We know there’s no such thing. There is no clean coal, only cleaner coal. Less dirty coal.” – Sen. Harry Reid (D) February 19, 2008 • Oil, natural gas and uranium are now considered “transient” resources: 60 years or less • Buildings comprise 30% of electricity use • Urgency for energy efficient and zero energy buildings • Los Angeles Green Building • Dodger Stadium Kayford Mountain, Appalachia AeroVironment Inc.

  6. Why Small Wind Turbines for the Built Environment? Distributed wind bypasses one of the most controversial aspects of wind power: siting large turbines in sensitive areas. Distributed wind intensifies urban development instead of encouraging sprawl. • Large wind turbines (>100kW) suffer from: • Structural requirements • Aesthetics • Noise & vibration • Inadequate resources • Siting: Zoning, FAA, etc. • NIMBY & BANANA • Small turbines can be fit into the built environment • AV’s focus on low-aspect ratio buildings AeroVironment Inc.

  7. Small Wind and the Built Environment Buildingsaccount for 30% of global electricity consumption. AeroVironment Inc.

  8. A New Implementation of Small Wind Small Wind generation results in pollution mitigation: Every kilowatt-hour of electricity produced using conventional fuels releases: - 1.26 pounds of carbon dioxide - 1.07 pounds of methane - 2.03 pounds of nitrous oxide • Building integrated wind turbines • Utility grid-connected • Modular and scalable • Complimentary with solar photovoltaics & green roofs • Rapidly and easily installed • Minimize roof penetrations • Fundamentally impact public perception of the relationship between energy production and energy use in the built environment AeroVironment Inc.

  9. Architectural Enhancements to Low Profile Buildings AeroVironment Inc.

  10. Building Integration Concept Investigation • Investigate Look & Feel – June 2004 • Long Beach, CA • Six turbines, 2.4 kW • Battery charging • Opinions of appearance… • Outdoor Wind Lab – June 2005 • Cabazon, CA • Utility grid-tied • Designed for 105 mph winds • Seismic and structural engineering • Wind flows over buildings • Three, five, and six blades Green: the new red, white and blue AeroVironment Inc.

  11. Aerodynamic Performance • Winds striking a building wall creates a frontal resistance to the wind • “Chimney Effect” for buildings with L/H > 5 • Creates a zone of accelerated air • 15% increase in velocity results in 50% more power • Power curve effectively shifts to the left • This phenomena can be analytically predicted AeroVironment Inc.

  12. Performance Optimization: Vector Flows • Turbine orientation with respect to accelerated wind flow is critical to maximizing energy AeroVironment Inc.

  13. Experimentation & Testing • 30 years of wind mapping experience • Experimental validation on structures • Cal Tech Lucas adaptive wind tunnel testing • Texas Tech Wind Science & Engineering Center: wind flow over low aspect ratio structures • Dynamometer testing • Mobile test platform • Computational fluid dynamics modeling 1:100 Scale Model – “Tilt-Up” Design Wind Vector AeroVironment Inc.

  14. “Architectural Wind leverages the ‘natural’ built environment… it is specifically engineered to take advantage of the acceleration effect of wind as it passes over the parapet” Key Finding: Accelerated Wind Flow Result: Three patents granted for Architectural Wind AeroVironment Inc.

  15. Partners in Innovation • Organizations with a commitment to sustainability • Climate change/GHG emission reductions • Environmental stewardship • Green building • Renewable energy • Want to engage stakeholders into this dialogue • Economic siting drivers: • Good wind resource (US Class 2+ or higher) • High electricity rates • Incentives (buydowns) BMW Group/Designworks, Newbury Park, CA AeroVironment Inc.

  16. Wind Siting: the Main Ingredient • Predominant wind direction • Boston vs. Boron • No obstructions upwind • Buildings • Trees • Hills • Facing side of structure • Focus on low aspect ratio buildings: • Distribution centers • Office buildings • Big box stores • Factories • Turbine pitch angle AeroVironment Inc.

  17. Attached is the master slide for AV presentations. Can you create a few slides with the payback of each sales price on one slide each (three slides). Also include one slide of the financials (MACRS, assumptions) and one of a good wind map. Case Study: Southern California AeroVironment Inc.

  18. Rapid Integration Onto Buildings • Mechanical interconnection: designed for concrete tilt-ups and pre-cast buildings • Plug & play electrical connectors with standard utility interconnection equipment AeroVironment Inc.

  19. 1st LEED Gold Certified Food Processing Plant Kettle Foods – Beloit, WI • Produce enough electricity to produce 56,000 bags of potato chips annually • Render used vegetable oil to produce biodiesel • Lighting & energy efficiency throughout • Preservation of local wetlands surrounding the facility AeroVironment Inc.

  20. Promoting Education & Awareness Adventure Aquarium – Camden, NJ AeroVironment Inc.

  21. Arizona State University: Global Institute of Sustainability AeroVironment Inc.

  22. Massport – Boston Logan Airport • Airports must balance their need for expansion and to reduce emissions simultaneously • Fuel efficient airplanes are on their way • Green buildings and electrification of runway equipment • Technology demonstration • 20 ea 1kW turbines • 60,000 kWh/year AeroVironment Inc.

  23. “When we are cabined in the present, we suffer from a certain poverty of imagination.  We massively underestimate human ingenuity and resilience.” • Daniel Pink • “I shut my eyes in order to see.” • Paul Gaugin "The tools we use to change the world ought to be beautiful in themselves. It's not just enough to survive. We've got to make something better than what we've got." - Alex Steffan AeroVironment Inc.
