25×20 Energy Benchmarking

The St. Louis High Performance Building Initiative is excited to challenge buildings in our region to benchmark building energy use, aiming for a 25% reduction in building energy consumption by the year 2020.

What is Benchmarking? It’s measuring how much energy a building consumes and comparing this to other buildings.

Why Benchmark? According, to ENERGY STAR data, buildings who benchmark for three years saw an average energy savings of 7%. You can’t manage what you don’t measure!

How can you get involved?

  • Step 1. Take the 25×20 Pledge to Benchmark Your Building.
  • Step 2. Find out how your building stacks up against similar facilities by enrolling in ENERGY STAR Portfolio Manager and benchmarking your building! Then report your data to the High Performance Building Initiative through ENERGY STAR, so we can track the region’s success.
  • Step 3. Use benchmarking results to inform your plans to save energy & money – and to aim for the goal of reducing energy use by 25% by the year 2020!

ENERGY STAR Portfolio Manager is a free and secure online tool that tracks energy and water consumption, as well as greenhouse gas emissions. Any building can use ENERGY STAR Portfolio Manager to manage energy and water use – schools, governments, congregations, businesses and retail stores. The 25 x 20 Benchmarking Campaign aligns with the City of St. Louis’ goal to reduce greenhouse gas emissions by 25% by 2020.

CHECK OUT THE 25 x 20 Collection on the Green Building Information Gateway (www.gbig.org), where all participants who have submitted their data to the High Performance Building Initiative are featured!
