Energy and Sustainability Additional Benefits Secured four solar AC units and accompanying solar panels at no cost to the District using a Pasadena Water and Power grant Secured $142,500 worth of LED lighting at no cost to the District through WeDIP Secured $59,842 worth of CFL lighting, ballasts, and occupancy sensors at no cost to the District through SC Edison Secured a 9.5 cent per kWh Power Purchase Agreement with PFMG Solar

Energy and Sustainability Post Conservation Program Concerns Cenergistic’s Experience Data shows approximately 67% of programs saved more with a second contract with Cenergistic “Just like driving a car, when you take your foot off the gas of the energy program, you’re going to slow down.” “The Cenergisitic program needs constant effort to achieve continued savings.” “In fact, when clients have ended their Cenergistic energy program, energy use has risen.”

Energy and Sustainability The California Clean Energy Jobs Act The California Clean Energy Jobs Act (Prop 39) was initiated when voters approved Prop 39 in November 2012. Prop 39 provides energy efficiency funds for five fiscal years ending in 2017-18 fiscal year. The District receives funds by submitting an energy expenditure plan (EEP) to the California Energy Commission (CEC). The energy manager was trained in 2013 to meet the guidelines necessary to receive the funds and take on all aspects of the Prop 39 program for the District.

Energy and Sustainability Additional Prop 39 Benefits As part of the EEP process, all projects done at sites must include an ASHRAE Level 2 audit and CEC paperwork. Completed Prop 39 projects done by the energy manager at Muir HS and Pasadena HS saved the District an additional $83,080. The cost of ASHRAE Level 2 audits for Muir HS and Pasadena HS is approximately $40,080. The cost of having the EEP paperwork completed is approximately $53,000. Both audits and paperwork completed by the energy manager cost less than $10,000 which was covered by Prop 39 funds.

Energy and Sustainability Sustainability Work Started discussions on environmental sustainability in 2011 leading to a reduction in paper consumption Officially, formed a District Green Team in 2014 Completed a Sustainability Circle in 2014 Created a Sustainability Action Plan in June 2014 Completed a national application for sustainability in December 2016 If time permits, will submit Energy Star applications for various District sites in 2017
