  1. Energy Management Planning

  2. Introduction Alan R. Mulak, PE 29 Ernie’s Drive Littleton, MA 01460 (978) 486-4484 amulak@comcast.net

  3. Introduction • Thank you • Credits! • My Opinion • Schedule

  4. EMP Seminar Outline • Today’s Schedule: • Before you begin the EMP…ask who, what, when, why, how. • First Steps…create the team, gather materials. • Next Steps… benchmarking, and energy audits. • Study the findings and make recommendations. • What will it cost? What will it save? • Finally, pulling it all together

  5. Why do we need an EMP? December 1, 2005 Electricity costs to skyrocket By DAVID SCHOETZSTAFF WRITER BARNSTABLE - The cost of the electricity supply for Cape Cod and Martha's Vineyard homeowners will increase by 81 percent starting with December meter readings. The cost of the actual electricity on residential bills will climb from 7.132 cents per kilowatt hour to 12.92 cents…. (Cape Cod Times)

  6. Why do we need an EMP?

  7. Why do we need an EMP?

  8. What if…? What if you are asked to develop an Energy Management Plan? Is it Mission Impossible?

  9. Before you begin… • Who wants the report? • Why do they want it? • When do they want it by? • What language do they speak? • How much do you want to spend?

  10. Before you begin… Form a team! Choose wisely!

  11. Before you begin… Who should be on your “Dream” Team?

  12. First Step Meetings • Invite only those who need to be there • Send them an agenda ahead of time • Start on time • Stick to the agenda • Take notes • Assign action items – everyone should get one • Adjourn on time • Issue minutes

  13. First Step Gather Materials • Energy bills: All fuels for at least 3 years. • Graphs! Pictures are truly worth 1000 words. • Drawings: Both building and equipment. • Physical descriptions, occupancy patterns, age, etc. • Pictures! • Specifications (if available) for all major equipment. • Preventative Maintenance program summary. • Written O&M Procedures.

  14. First Step

  15. First Step

  16. Next Steps Benchmark • Compare your buildings to each other and similar facilities. • Good performers? • See EPA Energy Star Building Portfolio Manager • https://www.energystar.gov

  17. Eligible Building Types Office Buildings Courthouse Hotels Schools Medical Offices Hospitals Grocery Stores Dormitories Warehouses

  18. Not All Buildings are Equal

  19. Fuel Efficiency: MPG Energy Efficiency: 1 - 100 What Does a Rating Tell us?

  20. Employing Portfolio Manager Screening tool • Identify poor performing buildings in need of improvements Scoping Tool • Use the generated score to determine course of action Evaluation Tool • Track and measure building improvements Energy Management Tool • Monitor building performance over time • Track building performance across all facilities

  21. Determining a Course of Action

  22. Before You Start: Collect Data Mandatory Data Needs • Zip code (to normalize data for weather) • Gross square footage of facility (includes secondary spaces) • 1 year of energy data (all fuel types) Helpful Data • (defaults may be used in lieu of this info to generate a rating) • Number of occupants • Number of PCs • Others (depending on space type)

  23. Getting Started:www.energystar.gov

  24. Login or New User?

  25. Eligible Space Types Note: Effective Date MUST be the same as the first date of the billing cycle for which you enter information.

  26. Energy Meters

  27. Meter Type/Unit

  28. Beginning Date of Bills

  29. Electricity Usage

  30. Results

  31. Questions? Contact: 1-888-STAR-YES energystarbuildings@epa.gov www.energystar.gov

  32. Award

  33. Next, the Energy Audit • Energy Audits: walk through vs. comprehensive energy audits • Smoking guns? Ask your team! • What can your utility tell you? • COM Check at www.energycodes.gov for code compliance and energy power density • HUD Commercial Audit info at http://www.globalgreen.org/pha-energytoolbox/energyaudit • Best Practices Guide http://www1.eere.energy.gov/femp/pdfs/omguide_complete.pdf

  34. Example Church Project: lighting (T12s) controls Results: 41% reduction in kwhrs 29% reduction in elec bill 1+ year payback

  35. Example College Project? ISO Load Response Program Results? • 280 KW predicted • 330 KW actual • plus kwhrs • plus LRP payment • plus AC reduction

  36. Example Navy Project: Uncontrolled Testing Labs Results: • Turn them off! • Savings - 14.8 MW to 8.2 MW

  37. Example • Project: • Hot water – 5 electric and 2 holding tanks off boilers • Results: • 8% reduction in kwhrs • $7500 cost for tankless • 2 year payback

  38. Energy Audit Survey • Lighting – simple, biggest bang for the buck. • Controls – roof vent fans? Exhaust hoods? Water heaters? • Old, neglected, out-of-tune equipment. • Leaky ductwork (air systems) • Hot air blowers • Steam Traps • Lack of O&M – filters, PM, etc. • Cooling Towers – VSD?

  39. Always… Layout Drawing Clipboard Flashlight 2 Pencils Tape Measure Camera Safety Glasses Sometimes… Light Meter Magnifying Glass Scrubby or Wipe CO2 Meter IR Thermometer Hand Tools (be careful) Energy Audit Tools

  40. Energy Audit Findings Three categories… • Immediate, ASAP. • Time bounded…next year or two. • Sometime in the future. Capital planning or further study required.

  41. Recommended Measures • Energy Conservation Measures (ECMs) with paybacks and rebates. • Automation such as PM and EMS’s. • Operational changes such as start and stop times, load shifting, etc. • Maintenance improvements. BOC! • Future upgrades (upon burnout).

  42. Recommended Measures ECM Basics: Simple Payback = Cost – Rebate / Savings

  43. Recommended Measures Cost? • This should be the total cost to install including labor, taxes, disposal, etc. • Sometimes, call in a contractor for a cost estimate. • Err on the high side.

  44. Recommended Measures Savings? • This should be the energy and if significant, labor savings. • When possible, have someone check your numbers. • Err on the low side.

  45. Recommended Measures • Rebates and Tax incentives? • www.energytaxincentives.org/ • USDA • Some resources: • www.utility.com • www.gasnetworks.com

  46. Energy Audits Case Study #1: Repair or Replace Boilers?

  47. Energy Audits Case Study #1: Benefits – 25% fuel savings (14,800 therms), reduced maintenance, less smoke Considerations – Cost! ($160,000 +/-) Help? – No. Savings in fuel - $29,466 at $2 per therm Payback – 5.4 years

  48. Energy Audits Case Study #2: Repair or Replace Chillers and Refrigeration System?

  49. Energy Audits Case Study #2: Benefits – Reliability! Electric savings (186,000 kwhrs), Maintenance Considerations – Cost! ($376,000) Help? – No. Savings in electric - $16,600 annually at $.07/kwhr Payback – 22.6 years

  50. Energy Audits Case Study #3: What to do about high ventilation / cooling expenses? Demand control ventilation?
