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. 5/17/2015 Energy Key Performance Indicator: BTUs/GSF

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

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

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

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

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

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
