  3. Content • Project Overview • Project Team • Process & Implementation • Major Findings • Post-Implementation Baseline Energy Usage • Energy and Cost Savings • Future Improvements

  4. Welch Hall Overview • Building constructed in 2001 • Total area of 179,222 square feet and four stories • Heating and cooling provided by the campus central plant • Original air handling unit design caused high fan energy and comfort issues • 5 air handlers, 195 terminal units, 9 exhaust fans

  5. Project Team Management Kenneth Seeton On-site CSU Dominguez Hills Facilities Personal MBCx Provider EnerNOC MBCx Implementation CSU Dominguez Hills EMCOR

  6. The Process • Meters installed and check for calibration • Pre-baseline data collected and Option C Baseline Created • EnerNOC verified what did and didn’t work; findings added to a punchlist. • Worked are way through a multi-page punch list • Nearly all repairs were made by staff RMs and BSEs • Brought Emcor in to install controller and do programing • EnerNOC field verified all the repairs by opening, closing, and testing every point • Post-energy data collected and savings calculated • Training / educational wrap up meeting

  7. Findings Log As A Punchlist

  8. 25 % Results Reduction in Annual Spending $108,306

  9. Pre-Investigation Baseline

  10. Pre and Post Baseline Comparison

  11. Energy Saving Measures Number of Instances Found 4 Measure Calibrate temperature sensors 2 Clean chilled water coils 1 Repair or replace non-functional valves 6 Repair or replace damper linkage or actuator 1 Raise economizer lockout temperature 3 Move temperature sensor away from heat source

  12. Future Improvements • Clean terminal unit reheat coils & re-TAB the building • Install turning vanes to reduce fan system effects • Implement a static pressure reset on air handling unit controls • Implement dual-setpoint occupancy flow at the zones

  13. Added Benefits of MBCx • How did this MBCx project help the campus with implementation and savings realization across campus • Everyone in my department became much more knowledgeable of the building • Employees saw the benefits of having things work correctly • Mechanics started to fix some of the same problems on other buildings or at least ask when we could get money to fix other things. • Finishing an MBCx gives a moral boost to the department and momentum to discover other savings on campus for a while
