Building Efficiency 305

The Building Efficiency 305 (BE305) program was created in response to the Miami City Commission's mandate to mitigate emissions of greenhouse gases and is intended to allow a data-based approach to analyze future energy needs, improve future usages, eliminate waste, and reduce costs.


The city of Miami has always been vulnerable to hurricanes, storm surges, and flooding, and we have a strong history of thriving in the face of adversity. However, over the past decade, Miami's acceptance and response to climate change has emerged as a new factor influencing the growth, and future trajectory, of the City. To ensure a sustainable and enduring future for the City and its residents, City of Miami is taking bold steps toward implementing an innovative and holistic approach to resilience.

Miami Forever Carbon Neutral is the City’s Greenhouse Gas Reduction Plan (GHG Plan) and a roadmap to achieve carbon neutrality by 2050. Today, commercial buildings contribute to approximately 35% of total emissions in the City of Miami, and tracking and reporting energy consumption through benchmarking programs is one of the first steps to understanding GHG reduction opportunities.

What is Benchmarking?

Energy and water benchmarking is a process whereby a building’s annual energy and water consumption data is joined with its physical and operational characteristics to create a comparable energy efficiency rating for that building.
This rating and other useful performance metrics allow a building owner to compare a property’s energy performance against itself over time as well as against similar buildings locally, regionally, and nationwide.
Annual benchmarking of energy and water consumption helps building owners, property managers, and facilities staff establish energy performance baselines, monitor performance over time, guide actions to cut waste, and verify energy and water savings from investments.
Benchmarking data provides summary information about public and private buildings, documenting trends in energy and water performance, and is the foundation for information to share with stakeholders. Benchmarking allows for a data-based approach to analyzing future energy needs, where improvements can be made and how to reduce costs.

Who's Required to Participate?

Building owners of multi-family and commercial buildings with 20,000 square feet or greater of floor space and 5 or more units are required to participate annually based on their reporting start date timeline.

What is the Timeframe?

Building Owners are initially required to comply with BE305 by either June 30th or October 1st, depending on building square footage. Buildings over 100,000 sq. ft. will first report their 2022 data in 2023. Learn more here.

What will the Report Include?

The annual benchmarking report includes basic building and property use information as well as a full 12 months of whole-building energy and water usage for the previous year. 


Building Owner Requirements

BE305 requires building owners of multi-family and commercial buildings with 20,000 square feet or greater of floor space and 5 or more units to benchmark every year.
