Early ’90 - Green Lights – Technology Focus

Mid ’90s - ENERGY STAR - Performance Standards & Labeling

Shift Focus to whole buildings and organization management

Late ’90s - ENERGY STAR Building Benchmarks & Labels

Partner of Year Award focused on “Program” vs “Project”

Early ’00s - ENERGY STAR Guidelines for Energy Management

Mid ’00s - Industrial Plant Benchmarks / Multiple Building Benchmarks

Late ’00s – ENERGY STAR Challenge for Industry

issues in the market
Issues in the market
  • Upgrading the technology did not always improve performance.
  • U.S. companies tended to focus on selective projects rather than continuous improvement.
  • Efficiency gains from improved O & M and “behavioral” changes overlooked or discounted
  • Uncertainty in gauging performance
management systems approach
Management Systems Approach

Focuses on

  • Organizational practices
  • Team development
  • Tracking & Measurements
  • Capital & behavioral projects
  • Communication & employee engagement

ENERGY STAR Guidelines for Energy Management

standardization of energy management
Standardization of Energy Management
  • ISO 50001 - Energy Management Systems underdevelopment
  • ANSI MSE 2001:2008 – Energy Management Standard
  • European Energy Management Standards
  • ASTM standards being developed for:
    • Compressed systems, motors, steam systems, etc.
why energy management systems
Why Energy management systems?

Companies with strong energy management programs:

  • Achieve greater results
  • Identify & implement better projects
  • Focus on continuous improvement
  • Have greater access to capital
  • Establish energy efficiency cultures
  • Sustain energy savings over time

Most companies and sites do not have strong programs:

  • Many companies lack formal energy programs.
  • “Managing energy” is done through ad hoc projects
the role of benchmarking
The role of benchmarking

An energy management system without good benchmarks is like a ship at sea with out a compass!

Benchmarks are the waypoints towards improved performance!

a barrier to greater efficiency

Uncertain bearing on efficiency


Provide a benchmarks as an objective measurement method of performance

ENERGY STAR Guidelines

for Energy Management

  • Can be based on comparison of management practices or energy data
    • practice benchmarking gives an idea of where to improve by identifying best energy management practices
    • energy data benchmarking informs how well an entity might perform and improve and the position of that entity in terms of energy performance
  • Benchmarking confirms if improvement projects have had an effect
types of benchmarking
Types of benchmarking
  • Internal
    • compares performance against internal baseline or benchmark
  • External
    • compares performance against a metric “outside” of the organization
    • identifies “Best in Class” performance
  • Quantitative
    • data-driven; compares actual numbers
  • Qualitative
    • based on best practices; compares actions
qualitative benchmarking
Qualitative Benchmarking

Energy Program & Facility Assessment Matrixes

Used to evaluate energy program practices & identify gaps

metrics shape approach
Metrics shape approach
  • Absolute
  • Intensity
  • Source vs. site energy
  • Normalized intensity
  • Ratings
the energy performance score

Fuel Efficiency:


Energy Efficiency:

1 - 100

The Energy Performance Score

Answers: “If all plants in the industry use energy as this one, what percent of plants in the country would be better, and what percent would be worse?”

energy star scores
  • External
    • Define “best in class” for an industry or building type
  • Sector Specific
    • Industry sector-specific at 6 digit NAICS code (or more refined)
  • Whole facility / building level
  • All fuels and energy sources
  • Source energy intensity
  • Intensity based on production
  • Normalized for key variables
  • Performance ranked on a scale of 1 to 100
energy star benchmarking tools
ENERGY STAR Benchmarking Tools
  • 2 Formats: Energy Performance Indicators (EPIs) - Industrial
  • Portfolio Manager – Commercial Buildings
industrial focus
Industrial Focus

Collaborative initiatives to develop resources for the industry

plant energy performance indicators
Plant Energy Performance Indicators
  • Spread-sheet based tools
  • Enable a higher level of energy management
    • Provides industry wide comparison
    • Enables better goal setting
    • Empowers management to require greater energy performance from plants
    • Provides opportunity for EPA recognition
application of benchmarking results

Reward & Learn

Invest & Tune








Application of benchmarking results

Best investment opportunities are in lower quartiles - greatest potential for improvement

RCx & O&M improvements yield savings and label candidates

High scorers provide lessons learned and label candidates

Energy Performance Score


energy star label
  • Must have an Energy Performance Rating of 75 or higher
  • Must pass an environmental compliance screen
  • 55 ENERGY STAR Industrial Plants have earned the label
    • Auto Assembly
    • Cement
    • Wet Corn Milling
    • Petroleum Refining
    • Pharmaceuticals
    • Food Processing
    • Glass Manufacturing
gauging sector performance
Gauging Sector Performance

EPA’s Experience with the Automobile Assembly Sector:

  • Based on ENERGY STAR benchmarking of auto assembly plants, EPA has seen fuel usage in the industry improve by 12 percent over a five year period.
  • The level of inefficiency has also dropped by 1.0 mmBtu/vehicle.
  • The range of performance has also narrowed.
    • This means that while the best auto assembly plants have improved, the others have more than "kept up" with this improvement.

ENERGY STAR Challenge for Industry

    • Plants establish an energy intensity metric;
    • Select an energy tracking system;
    • Create an Energy Tracking Planif their company does not have existing procedures.
    • Set a 10% improvement in 5 years goal.
    • Register their baseline annual intensity
    • Verify savings if goal is achieved.
  • Helps plants establish a culture of benchmarking that drives performance
  • Facilitates stronger management practices

First sites to achieve the ENERGY STAR Challenge for Industry

  • Empowers industry to shift the curve of energy performance
    • For most companies, the ENERGY STAR EPI is the first time they are able to see how their plants’ energy performance compares to that of their industry
  • Enables companies in the benchmarked industry to set competitive goals for plant improvement
  • Enables EPA to gauge improvement of an industry’s energy performance over time
