greenhouse gas emissions
Greenhouse Gas Emissions
  • 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.
csusm compliance with 987
CSUSM compliance with 987
  • Executive order 987
    • The CSU shall develop a strategic plan for energy procurement and production to reduce energy capacity requirements from the electricity grid, and to promote energy independence using available economically feasible technology.
new buildings
New buildings
  • Performance standards for new buildings of at least 20% better than Title 24
  • New buildings designed to meet LEED standards
  • Participating in SDG&E Savings by Design program
central utility plant
Central Utility Plant
  • 1.4 million gallon Thermal Energy Storage tank (TES).
  • Siemens Building Automation System
    • Schedule for equipment start and stop times
    • Schedule exterior and interior lighting
  • High efficiency air filters
  • Cog style belts for large air handlers
  • Continuous commissioning and monitoring of the existing buildings.
energy service company project esco
Energy Service Company project (ESCo)
  • Interior and exterior lighting retrofit projects
    • Exterior/High pressure sodium to T-5 florescent
    • Interior/Motion sensors, 32 Watt 5000K lamps and new diffusers
  • Central Utility Plant upgrades and energy efficiency projects
    • Boiler and chiller replacement
    • Variable primary pumping

future initiatives
Future Initiatives
  • Installing photovoltaic’s
  • Reviewing fuel cell technology
  • Future cogeneration plant
  • Additional buildings added to SiteSMART
  • Sub metering all buildings for electrical demand
  • Flow meters for chilled and hot water in each building
  • Comprehensive Building Management System
  • SiteSMART to pull all the data together and make it presentable.
  • DemandSMART provides incentive payment opportunity as well as meeting the load shed requirement.

Monitoring-Based Commissioning (MBCx)

  • Identifies a prioritized list of savings opportunities based on continuous analysis of the buildings operations.
sitesmart data driven energy efficiency
SiteSMART: Data Driven Energy Efficiency

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

and delivered in detailed energy dashboards and scorecards with savings recommendations

Thousands of data points from throughout the facility

are collected and analyzed by EnerNOC

csusm s enrollment in sitesmart
CSUSM’s Enrollment in SiteSMART
  • 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.
craven hall building

154,967 square‐foot building, estimated savings of 10% electricity and 15% for Heating Hot Water (in therms) using MBCx

university hall building
University Hall Building

71,300 square‐foot building, estimated savings of 10% electricity, and 15% for heating hot water(in therms) using MBCx program.

kellogg library building

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.

monitoring equipment installation
Monitoring equipment installation
  • Campus used existing sub meters and installed a BACnet compatible server.
  • EnerNOC installed the gateway to download the data.
audits monitoring
Audits & Monitoring
  • EnerNOC conducted a comprehensive audit at each building.
  • Baseline data starts being trended
measure installation
Measure & Installation
  • 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.
measurement verification
Measurement &Verification
  • 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.

Energy Savings

*Kellogg Library lighting retrofit increased heating loads during program

other benefits of m v for the campus
Other benefits of M & V for the campus
  • 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.
lessons learned
Lessons learned
  • 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)
