How did we do with utilities this past fiscal year?

With a second cold winter in a row the question arises "Just how did we do with utilities in FY15"? To put this into perspective we looked at a similar year, 2001. Fiscal year 2015 and fiscal year 2001 were similar years in terms of summer weather. Winter, however was slightly colder. FY15 had 7019 HDD (heating degree days) and 520 CDD (cooling degree days). FY01 had 6839 HDD and 509 CDD.

Having completed over 300 energy saving projects during these past 15 years, our FY15 electrical consumption was down 26.5%, gas consumption was down 27.5%, and water consumption was down 42.7% on a square foot basis compared to FY01.


The types of energy projects completed over the past fifteen years include the following:

  • Various Lighting Projects
  • Installation of Variable Frequency Drives
  • Purchasing power through the open deregulated market
  • Steam Traps & Steam Eye – Remote sensing for failures
  • OCC and CO2 Sensors used for Demand Ventilation Control 
  • Energy Contests amongst Housing Units
  • Temperature Setbacks – Unoccupied, Standby and Occupied
  • Installation of a new Chilled Water Bypass
  • Boiler Tune-ups
  • Burned different Fuel based on market conditions
  • Installation of an Aircuity system for Demand Ventilation Control in labs
  • Interconnection of Chilled Water Loop
  • Modification to Heating & Cooling set points
  • Steam Temperature Setbacks – Holiday breaks
  • AHU Scheduling coordinated with lighting and morning warm-up
  • Rain Gauge to assist in Scheduling Irrigation
  • DDC Controls/Compressor savings
  • Lighting Adjustments / Scheduling
  • Aggregating Natural gas to broker, not utility
  • Choosing Energy Source based on Economics – elected to heat by Natural Gas in lieu of Steam
  • Plumbing fixture selection providing water reduction
  • Coordinated snow melts sensors / improved operational performance
  • Adjusted mixed air temperature set points
  • Building Renovations (windows & temperature controls)
  • Replaced Pneumatic Controls with DDC Controls
