Where State Funded Schools

Stand in relation to the State of Arizona Energy & Renewable resources mandates


Energy codes
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


Energy codes1
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


Energy codes comparison
Energy Codes Comparison

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

Energy Codes Comparison

* Also minimum requirements of SFB Guidelines

Energy Codes Comparison

  • Conclusion:

    • Energy Codes are minimum requirements

    • The more recent the energy code the more stringent are the minimum requirements


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”


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



Points that would incur some additional costs ($3/sf to $8/sf) – 8 points

Total = 28 (Minimum 26 points for LEED Certified rating)


Points with higher initial costs and potential 8 year payback – 7 points

Total = 35 (Minimum 33 points for LEED Silver rating)


Ideas and Techniques with potential 8 year paybacks payback – - Waterless Urinals

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 payback – - Enhance building insulation

Suggest standard R-30 Roofs

Suggest R-19 Walls


Ideas and Techniques Elements with potential 8 year paybacks payback – - Reflective Coating on roofing system

Reduce heat gain through high-reflective

coating


Ideas and Techniques with potential 8 year paybacks payback – - Occupancy Sensors on regularly occupied spaces

Reduce energy by treating only

required amount of outside air

Occupancy Sensors cost approximately $150 per room


Ideas and Techniques with potential 8 year paybacks payback – - Daylight Sensors to harness daylight and reduce power consumption

Allow more window to wall area ratio - clerestory

Educational values


Ideas and Techniques with potential 8 year paybacks payback –

  • Providing adequate insulation on hot-water pipes

  • Providing Bi-level switching and dimmers


CONCLUSION payback –

  • 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
