Energy Efficiency Checklist

Increasing a building's energy performance is a continuous process of improving both building operations and systems. The first step to understand your building's performance is to measure your energy and water performance by benchmarking through ENERGY STAR Portfolio Manager. After benchmarking, the process of improving energy efficiency will be a bit different in each building, depending on current energy and water management practices and the age and efficiency of building systems.

Explore opportunities to save energy and invest in your building staff by checking out our Energy Efficiency Checklist.


Learn How to Comply with the City of St. Louis’s Building Energy Awareness Ordinance and the Building Energy Performance Standard Ordinance.

The City of St. Louis, USGBC-Missouri Gateway Chapter, BOMA St. Louis, Downtown STL, Inc and IFMA St. Louis Chapter are co-hosting three opportunities to learn how to comply. The events below are free to all, but space is limited. Registration is required.

Custom Alternative Compliance Plan pathway

Custom Alternative Compliance Path (CACP) path gives properties that are unable to hit their BEPS Target due to unusual circumstances the opportunity to customize a path that upholds the spirit of BEPS. Unlike the Paths 1-3, properties must apply to pursue a CACP and not all will be deemed eligible . Because pursuing a CACP is somewhat arduous and will take several months (not counting the implementation time), interested properties should plan ahead and take early action.

  • Custom Alternative Compliance Path (CACP) Eligibility Application- EXTENDED DEADLINE

    Saturday, September 30, 8:00 AM - 5:00 PM

    Properties that believe they need to pursue a CACP must first establish their eligibility. In an application to OBP, properties will select any of several qualifying scenarios (see Five Scenarios for CACP Eligibility page 36) and indicate how extenuating circumstances beyond the property’s control prevent it from complying with BEPS.


    Not all properties will be deemed eligible, as for some it may be more appropriate to pursue Path 3: Narrow the Gap to comply. 


    DEADLINE EXTENDED!!! The deadline to apply for eligibility is September 1st, 2023 has been extended due to the online application form crashing.
