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

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
