Data Driven Energy Audit Strategies

  1. 1. Data Driven Energy Audit Strategies Bennett Fisher Founder & CEO bfisher@retroficiency.com Phone: 202-744-4000
  2. 2. Even the experts agree – today’s audit process is frustrating at best Most Challenging Phase of Building Retrofit Retrofit Projects Market Opportunity (Survey of Auditors) Non-Financial Execution Challenges $400B Potential Projects $60B Realized Projects Source: Pike Research(c) 2012 Retroficiency, Inc. PRIVATE and CONFIDENTIAL 2
  3. 3. Organizations must answer these key questions to achieve a positive energy assessment outcome How many buildings 1 do I want to evaluate? Many One 2 What information do Energy Consumption Building Asset I have available? What resources are 3 appropriate given Manual Analytics Models project scope? What do I want the 4 outcome to be? ECIs ECMs(c) 2012 Retroficiency, Inc. PRIVATE and CONFIDENTIAL 3
  4. 4. Focus on the buildings that matter, and not those that don’t 1 Distribution of Portfolio Savings Potential Current Potential % of Savings Potential Spending ($) Savings ($) Building #1 $671,973 $250,626 Building #2 $939,946 $250,461 Building #3 $650,101 $220,326 Buildings Building #4 $1,146,006 $205,087 #1-#6: Building #5 $2,270,114 $104,701 75% Building #6 $308,458 $61,706 Buildings Building #7 $986,329 $59,251 Building #8 $225,025 $57,031 #7-#16: Building #9 $418,305 $55,640 25% Building #10 $421,414 $54,266 Building #11 $275,883 $38,989 Building #12 $334,848 $33,405 Building #13 $187,604 $28,243 Building #14 $2,743,762 $24,411 The top 6 of 17 buildings Building #15 $112,285 $9,394 (35%) in the portfolio have Building #16 $248,664 $0 75% of the savings potential. Building #17 $217,591 $0 Total $12,158,308 $1,453,537 Note: Building sample set from single utility portfolio.(c) 2012 Retroficiency, Inc. PRIVATE and CONFIDENTIAL 4
  5. 5. Interval and asset data can deliver insights, but should be used at different phases of the audit 2 Energy Interval Data Building Asset Data • Granular consumption data • General characteristics to Definition (e.g., readings every 15 minutes) detailed energy systems in the building • Request from utility • Interviews with owner / How You • (Larger) building operator Get It owners/operators may have • Building walk-through • Identify no-/low-cost operational • Scoping phase When You opportunities • Deliver detailed audit Use It • Determine retrofits to investigate recommendations(c) 2012 Retroficiency, Inc. PRIVATE and CONFIDENTIAL 5
  6. 6. Determine the approach that strikes the right balance between time, cost and measure(s) 3 Traditional Emerging Spreadsheets Detailed Modeling Analytics-Based • OK for lighting projects • Systematic input approach • Complex building models • Difficult to do more • Streamlines benchmarking Overview • Appropriate for highly complex systems and • Rapidly calculates potential customized projects ECM interaction measures Ease of Use Moderate Difficult Easy Time Investment Varies Significant Limited Required Expertise Some High Some(c) 2012 Retroficiency, Inc. PRIVATE and CONFIDENTIAL 6
  7. 7. ECIs help hone in on the right opportunities; ECMs should be developed closer to implementation 4 Energy Conservation Indicators Energy Conservation Measures • Lighting intensity is high during • Condensing gas boiler with a 91% unoccupied hours combustion efficiency • Appears to be simultaneous heating • Super T8 fixture with 3 30-watt lamps and cooling in building and electronic ballasts • Cooling system running constantly • Install air side economizer control with during high cooling degree days and dry bulb changeover control may be undersized(c) 2012 Retroficiency, Inc. PRIVATE and CONFIDENTIAL 7
  8. 8. Given those answers, managers should consider the best option given available time and budget Benchmark Level I Level II Level III Minutes or Weeks or Time: Hours 1-2 Days 3-5 Days Months Budget: <$500 $5K-$7.5K $10K-$20K $35K-$50K+ How many 1 buildings do I Many One want to evaluate? 2 What information Energy Consumption Building Asset do I have available? What resources are Spreadsheets Complex Model 3 appropriate given project scope? Analytics 4 What do I want the ECIs ECMs outcome to be?(c) 2012 Retroficiency, Inc. PRIVATE and CONFIDENTIAL 8
