16 Innovative Energy Practices within the California Community College System

17 Butte College Campus wide MBCx (aka Metering Project shhh) Ken Albright, MBA, CEFP

18 Prop 39 Doesn t Like Meters Meters, by themselves, cannot save energy (true) Managing energy consumption at the building level is not efficient without meters and data loggers (also true) Monitoring Based Commissioning (MBCx) is OK with Prop 39 (sorta)(still?) If an MBCx project can install meters and still achieve the Savings to Investment Ratio (SIR) it s OK Ergo: we found the SIR needed to install meters campus wide

19 Scope Install meters Total inhabited buildings 32 (one not included) Already had bldg level energy metering 2 LEED, 1 stand alone, 2 electricity only metered New meters installed 27 electricity 25 natural gas (all building don t have gas) No other energy inputs All connected to BAS to collect and record data Collect before data Retrocommissioning Collect after data

20 Costs Meter installation Electricity $99k Natural gas $76k Connection to BAS $125.5k Retrocommissioning programming $63.7k Commissioning agent $25.7k Total $389.9k Prop 39 $303k PG&E Incentive $118k Total $421k Funding

21 Retrocommissioning Working on only 8 buildings Total in project = 255,841 OGSF District = 785,717 OGSF ~33% of space Some of our biggest consumers of energy How did we know that? Low hanging fruit Projected 1 year savings $40, year NPV = $596,754 Sir = 1.4

22 Measurement & Verification In progress now Middle of summer not ideal for MBCx data collection Will extend into fall Confident we ll have more than enough savings Finding lots of problems to fix

23 The Moral of the Story It IS possible to have a metering project You just have to call it an MBCx project

25 CERRITOS COLLEGE INTEGRATED ENERGY MASTER PLAN

26 Cerritos College Campus

27 INTEGRATED ENERGY MASTER PLAN / CERRITOS COLLEGE Quick Facts Founded in ,000+ students (FTES) 135 acres 41 buildings, I million gsf $560 million for modernization and new construction $115 million operating budget $2.1 million annual cost of energy

28 INTEGRATED ENERGY MASTER PLAN / CERRITOS COLLEGE Green Cerritos College Environmental Stewardship Sustainability Initiatives Board Policy 3580 Environmental Sustainability Cerritos College Sustainability Plan Greenhouse Gas Reductions Energy Savings Water Conservation Green Education USGBC s LEED standard for projects above $5 million CCC/IOU Partnership first of akind Integrated Energy Master Plan

29 INTEGRATED ENERGY MASTER PLAN / CERRITOS COLLEGE Project Approach Create a comprehensive plan of holistic energy solutions Align with present state and future condition of campus Dual integration: intra campus and with California s guiding energy policies Real world solutions using a wide spectrum of applications A strategic roadmap for other institutions

30 Challenges Facilities master plan IEMP overlay One meter over 40 major buildings One gas meter Sub meters do not isolate the different load cooling load, lighting loads, plug loads and heating. Data gathered over 3 years to be effective Installation of permanent sub meters time consuming Electric circuits will need to be modified Temporary meters when installed are for a few months only

31 What do we know Facilities master plan and phasing Spatial mapping window, walls, footprint, etc Age of each building Codes determine performance and construction Climate files cooling and heating loads Light fixtures lighting consumption Types of mechanical systems central plant, roof top packaged system, VRF systems, etc Energy Upgrades will effect IEMP

32 Data Analytics Regression methods in predicting the accuracy of software. ASHRAE recommendation of consumption in sq ft CBECS method for consumption Utility Data for electricity gas and water Utility bill alignment 15 minute data for 3 years Calibration

37 Existing Energy Consumption By Building

38 Comparison of Cerritos College EUI, CBECS and Goal EUI

39 Green House Gas Emissions

40 Summary of Recommendations Apply Energy Design Guidelines for all new building design and construction Conduct ASHRAE Level II and I energy audits Continue to identify and implement energy efficiency and conservation measures Participate in cost beneficial Demand Response Program Assess and implement site specific renewable energy alternatives

41 Conclusion Road map: An integrated energy master plan overlay to facilities master plan Benchmarking the entire campus Help manage energy and energy costs, short, medium and long term Reduction in operational costs to better utilize funds for other initiatives Funding opportunities: utility rebates, Prop 39, bond funds
