Energy Efficiency Ratio (EER)
Benchmark
A rapid, decision-ready tool to identify true energy efficiency and cost-saving opportunities across large building portfolios.
Energy costs are rising and increasingly volatile, while organizations with large and dispersed building portfolios face growing pressure to reduce energy spend and emissions. Yet many struggle to clearly understand which sites are genuinely underperforming and where efficiency investments will deliver the greatest value. Widely used metrics such as Energy Use Intensity (EUI) and external benchmarks offer useful reference points, but they do not account for differences in building size, use, configuration, age, or operating conditions. This often limits their usefulness for prioritizing action.
RESET Carbon’s Energy Efficiency Ratio (EER) Benchmark addresses this challenge by applying the EER, defined as Actual EUI divided by Predicted EUI. By comparing how a building performs against how it is expected to perform under normalized conditions, EER separates structural energy use from true inefficiency. This enables organizations to rapidly screen large portfolios, identify underperforming assets, and size energy and cost-saving opportunities at scale, without relying on upfront site-by-site audits or detailed energy modeling.
Why Energy Efficiency Ratio Benchmarking matters
As energy prices increase and climate targets tighten, organizations need faster and more robust ways to direct effort and capital.
- Identify which assets are genuinely inefficient, rather than simply energy intensive
- Quantify the scale of opportunity before committing to detailed studies
- Prioritize sites and actions based on expected impact
- Support consistent, data-driven decisions across diverse portfolios
By normalizing performance across different buildings, EER provides a clearer signal for action than traditional benchmarking alone.
Our Energy Efficiency Ratio Benchmark services
RESET Carbon provides end-to-end support, from rapid portfolio screening through to validated insights and roadmap development.
PORTFOLIO-LEVEL EER BENCHMARKING
We apply regression-based energy modeling to assess performance across large and dispersed portfolios:
- Development of portfolio-specific regression models reflecting building characteristics and operating context
- Calculation of Predicted EUI and Energy Efficiency Ratio for each site
- Identification of underperforming and outperforming assets
- Clear, decision-ready visual outputs for technical and non-technical stakeholders
ENERGY EFFICIENCY OPPORTUNITY IDENTIFICATION AND PRIORITIZATION
We translate benchmark results into quantified energy and cost-saving potential:
- Estimation of reduction potential under defined improvement scenarios
- Internal comparison across sites, asset classes, and regions
- Identification of priority sites for deeper investigation or follow-up action
- Support for investment and sequencing decisions
BENCHMARK VALIDATION AND CONFIDENCE BUILDING
Where required, we validate benchmark insights against real-world findings:
- Comparison of EER-based results with targeted onsite assessments
- Confirmation of directional accuracy and order-of-magnitude estimates
- Strengthening confidence in results for executive and investment decisions
SCENARIO DEVELOPMENT AND NEXT STEPS
We support practical translation from insight to action:
- Scenario 1: Bringing underperforming sites to expected performance levels
- Scenario 2: Lifting portfolios toward top-quartile performance
- Quantification of energy and cost savings under each scenario
- Alignment with broader energy management and decarbonization strategies
