ENERGY EFFICIENCY FOR END-USERS

CSU Chancellors office coordinates the efforts to accomplish the goals established by Assembly Bill 32 for green house gas reduction.• California's major initiatives for reducing

greenhouse gas are outlined in AB 32, one of the goals is to reduce GHG emissions to 1990 levels by 2020.

Monitoring-Based Commissioning (MBCx)

Identifies a prioritized list of savings opportunities based on continuous analysis of the buildings operations.

SITESMARTSITESMART

SiteSMART: Data Driven Energy SiteSMART: Data Driven Energy EfficiencyEfficiency

Thousands of data points from throughout the facility

are collected and analyzed by EnerNOC

and delivered in detailed energy dashboards and scorecards with savings recommendations

Data is captured at the meter and behind the meter, then EnerNOC’s software continuously looks for equipment-level savings opportunities.

EnerNOC won the contract with the CSU through an RFQ process.

CSU Chancellors office provided funding to do MBCx in three of the CSUSM campus buildings.

200,530 square‐foot building, estimated savings of 11% electricity, 11% for Chilled Water, and 23% for heating hot water (in therms) using

MBCx program.

Campus used existing sub meters and installed a BACnet compatible server.

EnerNOC installed the gateway to download the data.

MONITORING EQUIPMENT MONITORING EQUIPMENT INSTALLATIONINSTALLATION

EnerNOC conducted a comprehensive audit at each building.

Baseline data starts being trended

AUDITS & MONITORINGAUDITS & MONITORING

EnerNOC issued the initial ScoreCard, with specific recommended measures.

The campus implemented the measures which were low cost – no cost maintenance items.

The measures that were implemented were submitted to the utility company for incentives.

– Some of the measures that were identified included:

• Loose belts , broken dampers, stuck hot water valves, and other maintenance items.

• Optimization of the VAV boxes and other controllers.

MEASURE & INSTALLATIONMEASURE & INSTALLATION

M&V reports were generated for the implemented measures.

The campus reviews the ScoreCard to see the impact of the implementations.

– The scorecards showed us the savings we provide the University by scheduling HVAC and interior lighting to be off during unoccupied times.

– The scorecards have identified several operational areas to help optimize plant operations.

The M & V reports created by SiteSMART were used to verify the savings we accomplished during our energy conservation project.

MBCx process will help us obtain LEED points for our new construction projects.

OTHER BENEFITS OF M & V OTHER BENEFITS OF M & V FOR THE CAMPUSFOR THE CAMPUS

The amount of data being transferred for a large campus requires a Building Management System that is BACnet compatible to operate efficiently.

Calibrate and verify all flow and kWh meters before recording the baseline data.

Communicate any other energy conservation projects to the MBCx team (this will effect incentive payment)
