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 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 Description ASHRAE ASHRAE IECC 2004 RoofR-15 WallsR-13 Glazing Shading Coefficient : 0.29 * Shading Coefficient : 0.46 * * Could be accomplished with low-e glazing; double-pane glazing; shading devices; awnings etc.

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

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

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
