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 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 “…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 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 Other LEEDers City of Phoenix City of Scottsdale ASU Commitment Arizona is currently ranked 10 th 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. Energy & Environmental Goals for Agua Fria
