What is Public building benchmarking?
Public building benchmarking is the practice of measuring the energy and water use of government-owned buildings and comparing them with similar buildings, their own history and targets. Many cities, counties and states benchmark public buildings in ENERGY STAR Portfolio Manager, sometimes because a local ordinance or state law requires it.
What it is
Benchmarking turns utility bills into comparable metrics such as energy use intensity and, where available, an ENERGY STAR score. It shows which buildings use more than expected for their type, size, climate and use.
Governments often lead by example, so many benchmarking ordinances apply to public buildings first or at lower size thresholds. Some jurisdictions also publish public building results.
Benchmarking by itself does not save energy. It prioritizes. The value comes from acting on the worst performers and then measuring whether the actions worked.
Who it applies to / where it is used
City, county and state facilities and sustainability teams, school districts, public universities and special districts. Requirements depend on the jurisdiction, so check the current ordinance or statute that applies.
How it is measured / what evidence it needs
Benchmarking needs complete, accurate whole-building data for every covered building, every year.
- Twelve months of energy and water data for each building
- Gross floor area and property use details
- Energy use intensity and score, where available
- Weather-normalized trends year over year
- Data quality checks for missing or estimated bills
How Aqueduct helps
Aqueduct supplies measured, validated consumption for every building, ready for benchmarking and for acting on the results.
- Utility bills and meter data are validated and gaps flagged before submission
- Metered consumption can be exported to ENERGY STAR Portfolio Manager
- Weather-normalized baselines show which buildings are truly improving
- The jurisdiction or owner submits its own benchmarking reports
