Energy Budget Goals

  • Primary Goal

– Reduce volatility of gas pricing by increased hedging – Currently at near historical low prices

  • Secondary Goals

– Increase outreach programs – Reduce average consumption

Monitoring Capability

  • FASER Version 5.0 Software (1999)

– Monitors all accounts with energy vendors – Database maintained by Accounts Payable since 2006 by Bruce Gerber/Michael Virone – Updates/Patches required

  • PowerLogic Square D Software

– Monitors on campus sub-meters – Ideally suited for electrical tracking/troubleshooting – Capable of energy use reporting

slide-5
SLIDE 5

Monitoring Capability

(Continued)

  • Andover Building Management System

– Capable of control, monitoring, and reporting – 150 Buildings can be controlled

  • Phoenix Control Systems (Lab Hoods)

– Used in Labs and Animal Care Facilities where airflow tolerances are critical

  • CT Water

– Monitors campus supplied customers

  • Metering Program – In process

– 30 water meters, minimal users – 20 electrical meters – 10 steam meters

Energy Hogs

  • Develop lists of Top Ten “Energy Hogs”
  • Encourage Energy Hog managers to

proactively administer conservation efforts

  • Develop conservation goals addressing issues

discovered

  • Pursue high ROI improvements
  • Distribute progress reports
