Accomplishments (Major Completed Projects) ⋅ 2012 – District wide – SAWS toilet Fixture replacement ⋅ 2011 – SPC-SWC - SECO Solar Panels ⋅ 2011 – District Wide – CPS Energy Audits ⋅ 2011 – District Wide – SECO ECRM Assessment ⋅ 2009 – District Wide – 4 day work week ⋅ 2008 – NVC Recycled water ⋅ Recycling ⋅ 2004 – PAC – 4 Day work week ⋅ 2003 – SAC, SPC and PAC - SECO ECRM Projects

Current Projects ⋅ NLC – Recycled Water ⋅ SAC – First Responders Academy Water line ⋅ SAC – First Responders Academy On Site Package Treatment Plant ⋅ District Wide – SECO projects ⋅ District Wide – Sustainability Policy and Procedures

Summer Energy Savings Initiative ⋅ Turn off boilers when outside air temperature is above 90 °F ⋅ Four day work week schedules. ⋅ CC® Measures Electricity (kWh) Demand (kW) Gas (CCF) Water (gallons) 2011 Total Savings 1,503,0541,96958,8544,572,231 Summer 2011 total cost savings: $199,194

New Building Optimization: CC ® measures implemented: September 20, 2011 Before CC ® After CC ® Before CC ® After CC ® ~ 25 % reduction in consumption Weather normalized trend data: ~35% demand reduction Performing Arts (Convocation) at Palo Alto College

Implemented CC ® Measures Supply air temperature reset schedule based on outside air temperature Supply air static pressure reset schedule based on outside air temperature ⋅ Reset schedules based on outside air temperature have been implemented this year at every campus.

Temperature and dead-bands: (Energy Conservation Code ) ⋅ Standard setpoints district wide to maintain a dead-band (minimum cooling and heating) of at least 5 °F Space Temperature CSPHSP Heating Band Cooling Band High Air Flow Low Air Flow HSP Heating Band CSP Cooling Band Space Temperature BeforeCurrently being implemented

Next Steps ⋅ Possible LEED Certified Projects –Manzanillo Hall at Northwest Vista College (In progress) –Mountain Laurel –Huisache Hall ⋅ District Wide Solar Panel installations where possible ⋅ PAC, SAC, SPC Rainwater harvesting

Recognitions and Presentations ⋅ 2010 ACUPCC award ⋅ 2007 TEES Mega Energy Saver Award ⋅ 2004 (?) CPS Energy Saver Award Presentations: ⋅ International Conference for Enhanced Building Operations (ICEBO) ⋅ Hot and Humid

Cumulative Savings
