“The slogan could be: Put it in writing and you will save! We reported the town energy usage in our annual report and now everyone has ideas to reduce town energy costs.” – Theresa Swanick, Effingham Energy Committee
"The Town of Plainfield, NH has benefitted from the use of Portfolio Manager to benchmark where we stood as compared to other municipalities as well as measuring our own progress as we moved the performance of our school from the 30th percentile to the 96th over a multi-year period. It also helps us monitor performance going forward to make sure we continue to maintain our progress. The Energy Committee for the town is having a similar experience as we work on the municipal buildings. If you don’t measure it, you can’t control it." -Allan, Plainfield NH
How to Benchmark:
1. Obtain digitized energy use data from your utility
Tracking energy involves obtaining usage data from electric and heating fuel providers. A few years (or at least one year) of historical usage data can help provide a good baseline of usage. Heating fuel data can be obtained from each respective fuel provider.
EPA’s FREE Portfolio Manager tracking tool will upload data from excel spreadsheets and provide reports on energy use for each building entered. Free tutorial or in person assistance is available for getting up to speed using Portfolio Manager.

Energy Benchmarking Defined: According to the US EPA, energy benchmarking is a first step in your energy management practices "that involve assessing energy performance, setting energy-savings goals, and regularly evaluating progress. Facility- or building-level energy performance benchmarking is an integral part. It provides the reference points necessary for gauging the effectiveness of energy management practices and management for continuous improvement."
Energy Benchmarking may also be referred to as an energy inventory.
EUI= Energy Use Index, the amount of energy used per square foot of building space.
kBtu = One thousand British thermal units. A British thermal unit is the amount of energyneeded to cool or heat one pound of water by one degree Fahrenheit. New Hampshire buildings may use oil, propane, gas, wood or steam. By converting energy into British thermal units, Portfolio Manager allows us to compare buildings that are heated by different sources.
Site Energy Use Vs. Source Energy Use
ENERGY STAR Portfolio Manager gives you two metrics for your building’s energy use, Site Energy Use and Source Energy Use. You’re probably already familiar with site energy, which is the amount of heat and electricity consumed by a building as reflected in your utility bills. Looking at site energy can help you understand how the energy use for an individual building has changed over time.
EPA has determined that source energy is the most equitable unit of evaluation. Source energy represents the total amount of raw fuel that is required to operate the building. It incorporates all transmission, delivery, and production losses. By taking all energy use into account, the score provides a complete assessment of energy efficiency in a building.
How Benchmarking & Tracking Energy Usage Benefits Towns NH Fire Stations: The following chart shows the amount of energy used per square foot in 12 New Hampshire fire stations in 2013. How does your town’s fire station compare?
