Benchmarking Jam

Partner Logos

Join the USGBC-Missouri Gateway Chapter and the St. Louis Green Business Challenge for a Benchmarking Jam! Energy benchmarking is the process of measuring how much energy your building consumes, and comparing your energy performance to similar buildings. Benchmarking is the first step toward saving energy and money.

The U.S. Environmental Protection Agency’s ENERGY STAR Portfolio Manager is an online, interactive energy management tool that allows you to measure and track your building’s energy, water, and waste consumption, identify investment priorities, and verify improvements over time. All buildings benefit from benchmarking: businesses, institutions, schools, congregations, non-profits and governments are encouraged to attend.

Following an overview of the basics of benchmarking, volunteers will assist building representatives to enter their data into ENERGY STAR Portfolio Manager and review the results.


  • Welcome
  • Why Benchmark? An overview of the benefits of benchmarking, the 25×20 Voluntary Energy Benchmarking Campaign, and the City of St. Louis’s Building Energy Awareness Ordinance.
  • Benchmarking Basics: Learn how to use ENERGY STAR Portfolio Manager, including answers to common questions
  • Hands-On Help Session: Get hands-on assistance using the free, online ENERGY STAR Portfolio Manager tool.

In order for this event to be a success, each building representative should bring:

  • Laptop or Tablet
  • The building street address, year built, and contact information.
  • Gross Floor Area (square feet)
  • Energy Use Data
    • Attendees will need at least 12 consecutive months of utility bills for all fuel types used in the building. Bring the number of units of each energy type used, not just the dollar amount of the utility fee.
    • Historical energy use data can be downloaded on the Ameren Missouri website and requested from the Laclede Gas customer service team.
  • Property Use Details: Additional required information varies by building type. See the list below.
  • Portfolio Manager Account: Attendees should create a Portfolio Manager account online here prior to the event.
