  • Over the next few minutes I’m going to be going over: Some background information about B3, Reasons why we benchmarking, How to create an account, how to add your energy bill data to that account, and finally how to analyze your data.
  • If your city does not already have an account, click on the CONTACT US on the mainpage.
  • It is really important to have the square footage of the buildings, or else most of the reporting tool will not work. You can also add different used for a building. Remember to determine the % of the uses.
  • Here you can see all the different types of buildings you can pick! This part is also very important for the benchmarking process. The engineering models are based on building type.
  • Look into demand consumption details.
  • So here we are on the building main page. We are currently viewing the “Summary” tab. Here you can see a glimpse at several different measurements like a DASHBOARD. These have more comprehensive pages on the tabs.
  • So here we are the Benchmark Tab. I keep using the word BENCHMARK, but what does it mean? 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 rating is a measurement of a site’s actual consumptions to its predicted benchmark.
  • BASELINE is used to compare a site to itself using a defined baseline period. The baseline is weather normalized so that changes in weather do not affect the comparison.
  • This is the Reporting Page, my favorite.
  • In this drop down menu you can choose from many different ways to view a report. I won’t go through all of them.
  • This shows the electric use in kilowatt hours yearly. You could look at the same in $.
  • So here is where that Target piece comes into play again. I created a target for this building to reduce it’s energy use by 20% from the 2009 usage. Here the report graphs out what a 20% reduction would look like, and allows me to see how our current use compares.

  • 1. B3 Benchmarking Sarah Steinman Minnesota GreenCorps Energy Conservation MemberAvailable to assist local units of government with B3 Sarah@CleanEnergyResourceTeams.org 612-625-3759 www.CleanEnergyResourceTeams.org
  • 2. B3 Benchmarking • Background • Why benchmark? • Account creation • Data collection and entry • Data analysis www.CleanEnergyResourceTeams.org
  • 3. B3 Benchmarking: Background B3 stands for:Buildings Benchmarking and Beyond www.CleanEnergyResourceTeams.org
  • 4. B3 Benchmarking: Background• 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. mn.b3benchmarking.com• Made in collaboration with the private design firm The Weidt Group www.CleanEnergyResourceTeams.org
  • 5. B3 Benchmarking: Background Public Buildings in B3Current Statistics• Number of Organizations 1,339 City• Number of Sites 4,879 1564• Number of Buildings 6,435 State• Number of Meters 10,242 2989 County• Total Square Feet 283,463,826 561 Public Schools 1321 www.CleanEnergyResourceTeams.org
  • 6. Why Benchmark? You Can’t Manage What You Don’t Measurewww.CleanEnergyResourceTeams.org
  • 7. Why Benchmark?Benchmarking your buildings can help answer some ofthe questions you may have about your energy use. • Which of my buildings are under-performing? • How can I compare yearly heating costs taking in account unusually high winter temperatures? • Is our City Hall energy efficient compared to others in Minnesota? • Are our buildings performing up to their expectations based on square footage and space usage? www.CleanEnergyResourceTeams.org
  • 8. Why Benchmark? Benchmarking is useful when your city, county, school district, or other entity……would like to find the “lowest hanging fruit” efficiency projects.…would like to demonstrate to others the value of your energy efficiency projects.…would like to participate in various financing projects. www.CleanEnergyResourceTeams.org
  • 9. Account CreationThe following slides briefly go over how to create a B3 account and how to utilize the features. ACCOUNT CREATION DATA COLLECTION DATA ENTRY ANALYSIS www.CleanEnergyResourceTeams.org
  • 10. Account Creationmn.b3benchmarking.com www.CleanEnergyResourceTeams.org
  • 11. Account Creation: Building Editor When creating an account, it is crucial to enter the Square Footage of the building. Also, Specify theSpace Usage Type www.CleanEnergyResourceTeams.org
  • 12. Account Creation: Building EditorThere are many spaceusage types fromwhich to choose. www.CleanEnergyResourceTeams.org
  • 13. Data Collection Data Collection ACCOUNT CREATION DATA COLLECTION DATA ENTRY ANALYSISwww.CleanEnergyResourceTeams.org
  • 14. 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 theirutility 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 www.CleanEnergyResourceTeams.org
  • 15. Data Collection Data Collection ACCOUNT CREATION DATA COLLECTION DATA ENTRY ANALYSISwww.CleanEnergyResourceTeams.org
  • 16. Data EntryOnce historic data is in the system, monthly dataentry is quick and easy.Often, the staff person that pays the utility bills isable to spend a few minutes each month entering thenew data into B3 www.CleanEnergyResourceTeams.org
  • 17. Data CollectionExample ofwhere to find therelevant data onyour bills for B3 www.CleanEnergyResourceTeams.org
  • 18. Analysis ACCOUNT CREATION DATA COLLECTION DATA ENTRY ANALYSISwww.CleanEnergyResourceTeams.org
  • 19. Analysis: Summary Tab Your Building’s “Dashboard” These measures have their own tab at the top that offer more detailed information www.CleanEnergyResourceTeams.org
  • 20. Analysis: Summary Tab kBtu/SF/YearThis measure is a very importantnumber to know. It is like an MPGfor your car, but for your building.This building is using 79.73 kBtu/SF/Year www.CleanEnergyResourceTeams.org
  • 21. Analysis: Benchmark Tab Note that LESS than the benchmark is GOOD 79.73(actual) .89 In B3, “benchmarking” is an engineering model (ratio) that predicts how much energy a site would use if 89.47 it were built to today’s energy codes. The B3 ratio (prediction) is a measurement of a site’s actual consumptions to its predicted benchmark. www.CleanEnergyResourceTeams.org
  • 22. Analysis: Benchmark Tab Baseline is used to compare a site to itself using a defined time period. The baseline is weather normalized so that changes in weather do not affect the comparison. www.CleanEnergyResourceTeams.org
