The Role of Benchmarking in Promoting Strong Energy Management Systems Walt Tunnessen US Environmental Protection Agency ENERGY STAR Industrial Partnership May 21, 2010
Evolution EPA Efficiency Initiatives 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 • 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 Focuses on • Organizational practices • Team development • Tracking & Measurements • Capital & behavioral projects • Communication & employee engagement ENERGY STAR Guidelines for 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? 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 An energy management system without good benchmarks is like a ship at sea with out a compass! Benchmarks are the waypoints towards improved performance!
Barrier Uncertain bearing on efficiency Solution Provide a benchmarks as an objective measurement method of performance A barrier to greater efficiency
Benchmarking’s place in energy management 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 • 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 Energy Program & Facility Assessment Matrixes Used to evaluate energy program practices & identify gaps
Metrics shape approach • Absolute • Intensity • Source vs. site energy • Normalized intensity • Ratings
Fuel Efficiency: MPG 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 • 2 Formats: Energy Performance Indicators (EPIs) - Industrial • Portfolio Manager – Commercial Buildings
Industrial Focus Collaborative initiatives to develop resources for the industry
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 • www.energystar.gov/epis • www.energystar.gov/industrybenchmarkingtools
Reward & Learn Invest & Tune Tune Invest 100 1 25 50 75 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 19
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 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.

Promoting internal benchmarking 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
Results First sites to achieve the ENERGY STAR Challenge for Industry
Summary • 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
