- The State of Minnesota B3 Energy Benchmarking program has
been developed by the State of Minnesota Department of Administration and Department of Commerce to help State and local governments improve the energy performance of their buildings by tracking and managing facility energy consumption.

Why Benchmark?
Benchmarking is useful when your city, county, school district, or other entity would like to:
Find the “lowest hanging fruit” efficiency projects. Participate in various financing projects. Complete an action in the GreenStep Cities program. Demonstrate to
- thers the value of
your energy efficiency projects.

Data Collection
- Historic energy data will need to be collected from your utility.
- 3 Years is preferable
- Local government entities can get this historic data from their
utility provider.
- Data needs to include:
- Start and end date of meter reading
- Consumption in therms, kWh, gallons of fuel, etc
- TOTAL billing amount in $
- Electric demand charges if available

Data Entry
Once historic data is in the system, monthly data entry is quick and easy.
Often, the staff person that pays the utility bills is able to spend a few minutes each month entering the new data into B3.

Analysis: Summary
kBtu/SF/Year This measure is a very important number to know. It is like an MPG for your car, but for your building.
This building is using 79.73 kBtu/SF/Year

Analysis: Benchmark
www.CleanEnergyResourceTeams.org
In B3, “benchmarking” is an engineering model that predicts how much energy a site would use if it were built to today’s energy codes. The B3 ratio is a measurement of a site’s actual consumptions to its predicted benchmark.
Note that LESS than the benchmark is GOOD
89.47 (prediction) .89 (ratio) 79.73 (actual)

Analysis: Benchmark

See that MORE than the benchmark is BAD
Sites that use more energy than the benchmark are good candidates for an energy audit.

New Features
www.CleanEnergyResourceTeams.org
Features that will be rolled out in 2013
- Advanced Benchmarking - further define building spaces, parameters and
- perations to improve the accuracy of the benchmark ratio and opportunities for
improvement
- Improvement module - Identify buildings to improve
and create plans to track progress
- Water Consumption Tracking - New mode to track and
baseline the water consumption for your organization and buildings.
- Integration with upgraded ENERGY STAR Portfolio Manager -
ENERGY STAR is overhauling their website and services so we'll be overhauling how we integrate and share B3 data with Portfolio Manager.

FAQ: Weather Normalization
www.CleanEnergyResourceTeams.org
Weather Normalization mathematically adjusts the energy consumption figures to factor out any variations outside air temperature may have had allowing for an "apples to apples" comparison of one periods of time's energy consumption to another period of time. Example: you used less energy in 2010 than 2009 so is that savings related to more efficient operations or due to the fact that the winter of 2010 was warmer than 2009 thus you would expect to use less heating energy in 2010. Unlike many programs which use heating and cooling degree days, the B3 Benchmarking system uses an algorithm to determine the nonlinearity relationship between load and temperature thus establishing the appropriate curve and balance point.

FAQ: Benchmark
www.CleanEnergyResourceTeams.org
B3 Benchmarking automatically creates an energy Benchmark for each
- site. The benchmark is a prediction of the site’s consumption based on an
engineering model of the buildings and space types, constructed as if each building were built to the current Minnesota Energy Code. Actual consumption of the site will vary from the benchmark. If the variance is large, you should check all your building and meter reading data. The Benchmark is designed to be a good screening tool to identify sites that need attention. Sites that use more energy than the benchmark are good candidates for an energy audit.
