  1. The Solar PathNorth Carolina Association of Higher Education Facilities OfficersAnnual Conference March 7-8th, 2012 Photo by Roger Winstead.

  2. NC State University and Renewables • Solar Center Continuing Education • DSIRE Database • Advanced Energy • FREEDM • Energy Management • Sustainability Office

  3. Solar on NC State Campus 6 kW 40 kW 8 solar thermal panels 75.6 kW 3 kW 30 solar thermal panels + 112 pool heating collectors

  4. NEXT 40 YEARS - CLIMATE NEUTRALITY

  5. 2008 Greenhouse Gas Inventory

  6. HOW NC STATE COMPARES

  7. Impact of Near Term Strategies 20% GHG reduction in 2015

  8. Energy Key Performance Indicator: BTUs/GSF

  9. ENERGY CONSERVATION 2015 Goal 2015 Goal = 30% reduction of energy use compared to 2003

  10. PYRAMID OF CONSERVATIONTHE POWER OF ONE If behavior change can account for 5% of electricity reduction, how much $ will NC State save? Diagram: Minnesota Power: http://www.mnpower.com/powerofone/one_home/index.htm

  11. Why solar? • Student demand • Research opportunities • Public perception • Clean, renewable energy • Climate Action Plan

  12. Why not solar? • High relative cost for carbon reduction • Efficiency first • Perception: New technology • Perception: Onerous process

  13. The Solar Path • Use this procedure when a viable project is identified • Contains many of the forms needed • Very similar across state funded organizations

  14. Procedure Diagram • Insert diagram here

  15. Frequently Asked Questions • Glare • Liability • Wind • Roof warranty

  16. Solar Power for your University • Replicate our procedure • Contact us for more information

  17. Intern Project: Site Suitability Survey • Description of the project

  18. 10 criteria • Rooftop Access • Roof Install Date • Roof Type • Roof Area • BTUs/ GSF • Impediments • Orientation • Pitch • Visibility • Shade

  19. Impediments • Any object on the roof that impedes placement of a solar array either through • Physical presence • Casting of a shadow

  20. High Impediments - Dabney 50%< Roof Impeded

  21. Low Impediments - Witherspoon 25%> Roof Impeded

  22. Orientation • Determined along the long axis of the building • Ideal Orientation is E-W

  23. Carmichael gymnasium N

  24. Visibility • Determined by Walk-By Site Assessment • Low = >25% of roof visible • Medium = 25% - 75% of roof visible • High = > 75% of roof visible

  25. Low Visibility - Dabney

  26. High visibility - Jw isenhour tennis center

  27. Shading • Extent to which objects cast a shadow on rooftops • Low: >25% Shaded • Medium: 25% - 75% Shaded • High: <75% Shaded

  28. High shading - Turner House

  29. Low Shading - Centennial sub station

  30. Rooftop Access • Availability of perimeter space for crane use • Low: If materials can’t be stored on roof or no reasonable crane access • Medium: 1-2 sides available • High: 3+ sides available

  31. Low - lEazar hall • Materials can’t be stored on roof and no reasonable crane access points

  32. High - mckimmon center • 3 crane access points

  33. Roof Install date & Type • Date of most recent roof install • Type of roof currently installed

  34. wood deck with Asphalt shingles

  35. Wood deck with Slate Shingles

  36. Epdm • EPDM rubber stands for Ethylene Propylene Diene Monomer (M-class)

  37. Coal Tar Pitch

  38. Roof Area • Measured in ft^2

  39. conclusion • This project was almost completely student led • There are several existing systems on NCSU’s campus • Rooftops evaluated based on 10 criteria

  40. conclusion • John Galloway - jwgallow@ncsu.edu • Alex Crouse - ascrouse@ncsu.edu • Liz Bowen - Liz_Bowen@ncsu.edu

  41. Sponsors
