Where State Funded Schools

1. Where State Funded Schools Stand in relation to the State of Arizona Energy & Renewable resources mandates

2. Energy Codes • Arizona – Home rule state – codes are adopted and enforced on a local level. • 21 local municipal governments have adopted energy codes • ASHRAE – American Society of Heating, Refrigerating and Air-Conditioning Engineers – is a national model code that may be adopted by state or local governing body (ASHRAE gets revised every few years) • IECC – International Energy Conservation Code – another national model code that may be adopted by state or local governing body (IECC gets revised every few years) • For the most part the recent versions of both the codes are slightly different in their requirements

3. Energy Codes • Design Professionals are required to comply with the corresponding local energy code to get a building permit • All state owned or funded new buildings must comply with ASHRAE 2004 • 14 Jurisdictions have adopted IECC 2003 (example: Tucson - Sustainable Energy Standard) • 2 Jurisdictions have adopted IECC 2000 (example: Pinal County) • Only Phoenix has adopted IECC 2004 to date

4. Energy Codes Comparison * Could be accomplished with low-e glazing; double-pane glazing; shading devices; awnings etc.

5. Energy Codes Comparison

6. Energy Codes Comparison * Also minimum requirements of SFB Guidelines

7. Energy Codes Comparison • Conclusion: • Energy Codes are minimum requirements • The more recent the energy code the more stringent are the minimum requirements

8. LEED • Leadership in Energy and Environmental Design (LEED) – a Green Building Rating system developed by U.S. Green Building Council (USGBC) • National Standard for developing high-performance sustainable buildings • Rating system with 69 possible points • Four Levels of Rating • Certified – Minimum 26 points • Silver – Minimum 33 points • Gold – Minimum 39 points • Platinum – Minimum 52 points • Executive Order 2005-05 requires all state-funded buildings to meet at least LEED Silver standards “ to the extent practicable”

9. LEED • LEED certification requires Commissioning of buildings • LEED pursuit involves commissioning fees, application fees and review fees • Five major Categories • Sustainable Sites • Water Efficiency • Energy & Atmosphere • Materials & Resources • Indoor Environmental Quality

10. Easily achievable points that does not incur additional costs - 20

11. Points that would incur some additional costs ($3/sf to $8/sf) – 8 points Total = 28 (Minimum 26 points for LEED Certified rating)

12. Points with higher initial costs and potential 8 year payback – 7 points Total = 35 (Minimum 33 points for LEED Silver rating)

13. Ideas and Techniques with potential 8 year paybacks- Waterless Urinals Less Maintenance No Flush Control No Sensors No Water leaks 1 to 4 years payback Educate Maintenance staff Low installation costs

14. Ideas and Techniques with potential 8 year paybacks- Enhance building insulation Suggest standard R-30 Roofs Suggest R-19 Walls

15. Ideas and Techniques Elements with potential 8 year paybacks- Reflective Coating on roofing system Reduce heat gain through high-reflective coating

16. Ideas and Techniques with potential 8 year paybacks- Occupancy Sensors on regularly occupied spaces Reduce energy by treating only required amount of outside air Occupancy Sensors cost approximately $150 per room

17. Ideas and Techniques with potential 8 year paybacks- Daylight Sensors to harness daylight and reduce power consumption Allow more window to wall area ratio - clerestory Educational values

18. Ideas and Techniques with potential 8 year paybacks • Providing adequate insulation on hot-water pipes • Providing Bi-level switching and dimmers

19. CONCLUSION • For our schools to be the most energy efficient and sustainable will require a holistic approach to the design and continuing education for the users
