Master Utility Spreadsheet
37 different tabs. Electrical Usage (kwh), Electrical Demand (kW), Electrical Cost, Outside
Lighting Cost, Steam Usage, Natural Gas Usage and Cost, Dumpster Cost, Building
Information (Square Footage/Renovation), Budget per Utility, Street Addresses,
Heating/Cooling Degree Days are all incorporated into the Master Utility Spreadsheet.
Department of Facilities Management
Maintenance & Operations
• Currently has five years of utility data
• Has been essential in forecasting utilities
• Has streamlined billing to auxiliary enterprises
• Has not increased time required for data
management due to the fact that data requires
entry into spreadsheet somewhere
• Has proven to be an excellent tool when working
with outside engineering firms (eg. ESCO’s,
commissioning agents, electrical provider, etc.)

Energy Use Index spreadsheet allows analysis of how buildings are performing.
Department of Facilities Management
Maintenance & Operations
Energy Use Index (Energy Use Intensity) is a unit of measurement that describes a building’s
energy use. This represents the total energy (electricity, natural gas and steam) consumed by a
building relative to its size or square footage.
The electrical usage (kWh) and steam usage (pounds) are converted to a common measure of
BTU (British Thermal Unit) and combined.
This measure of energy usage is then divided by the square footage to give you the usage per
square foot.
This Energy Use Index can be used to provide a benchmark to compare facilities and/or a
building against itself when energy conservation methods are pursued.
The Energy Information Administration (Department of Energy) provides some information for
comparison benchmarking and national averages on EUI and kWh usages per square foot for
colleges and universities.
Department of Facilities Management
Maintenance & Operations
• Allows comparison with external organizations
with different utility rate structures
• Allows comparative reports to be developed
between similar facilities or groups of facilities
• Information from EUI’s is used to target facilities
for inspection or retro-commissioning based on
performance

Sub-Metering at Building Level

Department of Facilities Management
Maintenance & Operations
Digital Sub-Metering- Allows for trending of data
based on defined parameters
Consistency and reliability of data from meters is
critical - do your homework (e.g.. installation
requirements, turn down requirements,
compatibility with building automation systems,
cost to calibrate, need for calibration)
Targeting of buildings or systems that are outliers

Lessons Learned
• Ensure decisions are data driven
• Verify estimates and forecasts for projects
against “actual” data
• Don’t become “attached” to a project/idea
• Don’t overlook the importance of routine
maintenance
• Capital renovations will have the most significant
impact to energy conservation

Where are we going?
• Natural Gas Cogeneration?
• Remain focused on reducing electrical demand
(magnetic bearing chillers, precinct chill water,
vfd’s, Capital and Maintenance Reserve
Renovations, improved controls strategies)
• Development on “Design Standards” for controls
strategies and sequences of operations for
systems management
• Increase Retro-commissioning efforts
