Agua Fria District Energy Strategies

Governing Board Energy Policy Faculty and Staff awareness and

participation in good practices Monitoring energy consumption and

feedback to building occupants and designers

Cost-effective systems and building design practices which enhance learning

SFB New School Design Criteria

• Building Envelope per ASHRAE 90.1-1999

• Energy Star Roofing Materials – reflectivity

• Lighting – T8 w/ Electronic Ballast (minimum), Occupancy Sensors, LED Exit signs

• HVAC compliant with DOE Federal Energy Management Program – Energy Star

• Controls – Occupancy Sensor or Schedule

• Utility Consumption Monitoring

Energy Conservation Mandates

Governor’s Executive Order 2001-3“…all public schools in the State of Arizona shall be

designed and constructed in a manner to reduce

energy consumption and create more energy efficient

facilities…”

Governor’s Executive Order 2005-05

All new state-funded buildings shall have three characteristics:

• Meet at least the LEED “Silver" standard

• Derive at least 10 percent of energy from a renewable resource

• Include energy efficiency standards consistent with AZ Revised Statutes 34-451

Other LEEDers

• City of Phoenix

• City of Scottsdale

• ASU Commitment

• Arizona is currently ranked 10th in LEED buildings

•Select and install low-emitting materials which will improve indoor environmental quality and decrease negative impacts on health and the environment.

•Attempt to match materials that are installed in the existing structures with environmentally-preferred alternatives, as appropriate.

•Implement recycling programs and policies to ensure that both construction and normal day-to-day waste streams are reduced and diverted away from the landfill.

•Implement sustainable construction methods that reduce negative impacts on the learning environment, support pollution reduction, and minimize disruption at the campus.

Energy & Environmental Goals for Agua Fria

•Seek to demonstrate innovation whenever possible, to enhance the educational experience for students, staff, teachers and the community.

•Seek appropriate awards and certifications associated with this environmental design and building program to enhance the educational experience for the student, district and community at large

Energy & Environmental Goals for Agua Fria

•Enhance the student learning environment by implementing innovative design strategies, paying careful attention to comfort, noise, glare, and indoor environmental quality.

•Maximize energy-effective daylighting design to enhance the learning environment and reduce energy expenditures.
