  11. What is DEER? • A collection of data for Residential and Non-Residential energy efficiency measures. • It provides a common set of: • Ex ante Savings values: kW, kWh, kBtu; • Measure Costs; and • Effective Measure Life (a.k.a EUL)

  12. Previous DEER Database • Savings estimates and cost estimates were never integrated • Database on hard copy and soft copy • Commercial measures savings had not been updated since 1994 • Residential measures savings more recently in 2001 • No information on EULs

  13. DEER Update • First Phase of DEER Update began in 2003 and included: • Updating savings for non-weather sensitive measures • Updating weather-sensitive models and the software –Measure Analysis Software • Creating a searchable, on-line database

  14. DEER Update • Second Phase of DEER began in 2004 and included: • Revised non weather sensitive lighting measures savings estimates • Completed the Measure Analysis Software for weather sensitive analysis • Developed a limited number of “High Priority” weather sensitive measure savings estimates • Integrated measure cost into the database • Partial release Milestone completed on March 2005 • Frozen to support June 1st EE filing

  15. DEER Update • Final DEER milestone Completed on-line DEER version 2.0 on August 31, 2005 • Supercedes March 2005 DEER version 1.0 • Revised non-weather sensitive data • Added new and updated weather sensitive measures • Added Agricultural measures • Integrated new effective useful life estimates • Completed integration of cost data • Updated the website with the new information

  16. DEER Update Final Report Milestones • Draft Final Report - Sept 30th for PAC • Final Report - October 31st

  17. DEER Update • TOU Profiler– Currently TBD • Too many other issues; other items with higher priority • Definition of kW • Calibration • Unification of kW definition across all measures and end uses • Agreed initially: • Create a Time of use Profiler • Will utilize the DEER eQuest model • The model will be available for download • Preliminary estimate of amount of data • More discussions needed

  18. Measure Cost Study (MCS) Project Team • Marshall Keneipp, Summit Blue Consulting (Project Manager) • Floyd Keneipp, Summit Blue Consulting • Joshua Radoff, Summit Blue Consulting • Cathy Chappell, Heschong Mahone Group, Inc. • Cynthia Austin, Heschong Mahone Group, Inc.

  19. MCS Project Overview • Undertaken to update measure cost estimates within DEER • Previous update conducted in 2001 • Parallel completion schedule to DEER Update • High priority measures complete in March 2005 • Full update completed in August 2005

  20. Measure Cost Study (MCS) Project Scope of effort • 814 separate costs were collected on 287 measure IDs • Many measure IDs have one cost • Some measure IDs have costs for multiple bins (i.e. capacities, purchase volumes, etc.). For example measure D03-410, residential condensing 90 AFUE furnace, has 10 costs - one cost for each of 10 Btu capacities • 625 separate base costs were collected • Some measures were full cost only and did not require base cost estimates • 574 measure labor cost were collected • Some measures were incremental equipment costs only and did not require a labor cost estimate • A total of over 12,100 individual cost observations were collected

  21. Questions/Comments?

  22. Development of DEER ProductsNon-Weather Sensitive Energy Savings Presenter: Gary Cullen – Itron

  23. Non-Weather Sensitive MeasuresResidential Measures • CFL Lighting • Refrigerators • Clothes Washers & Dryers • Dishwashers • Water Heating • Swimming Pool Pumps

  24. Non-Weather Sensitive MeasuresResidential Measures • CFL LightingMeasure Impact = (delta watts/unit * hours/day * days/year * In Service Rate) / 1000 watts/kWh Demand Impact =delta watts/unit * In Service Rate * Peak Hour Load Share The “In Service Factor” is an estimate of the percentage of lamps that are actually used. It is a rough estimate based on utility experience. “Hours of Operation/Day” and “Peak Hour Load Share” from KEMA CFL Metering Study

  25. Non-Weather Sensitive MeasuresResidential Measures • CFL Lighting – Example (14W CFL replace 60W Inc)Measure Impact = (46W * 2.34 hours/day * 365 days/year * 0.9) / 1000 watts/kWh = 35.4 kWh Demand Impact = 46W * 0.9 * 0.081 = 3.35 W

  26. Non-Weather Sensitive MeasuresResidential Measures • RefrigeratorsUsed the Energy Star calculator available on-line at: http://www.energystar.gov Key Input values for the calculator: Refrigerator Type (top, side, or bottom mount freezer) Ice through the door (yes or no) Refrigerator fresh volume (cubic feet) Refrigerator freezer volume (cubic feet)

  27. Non-Weather Sensitive MeasuresResidential Measures • Clothes Washers Utilized the three recommended Consortium for Energy Efficiency (CEE) Tiers for Modified Energy Factor:Used the Energy Star calculator (that utilizes an EF rather than MEF) on-line at:http://www.energystar.gov Estimated the equivalent EF value for CEE MEF values from Energy Star list of approved washers Other key Energy Star variables include: Number of wash cycles/year (E Star value is 392 cycles) Washer capacity (three sizes – 1.5, 2.65, and 3.5 cubic feet) Further disaggregated impacts by water heat and clothes dryer fuel types Fuel impact disagreegations based on ‘Efficiency Vermont” estimates Demand impact based on a energy/peak factor of 0.417. This is carryover from previous 2001 DEER

  28. Non-Weather Sensitive MeasuresResidential Measures • Clothes Washer – Example (Tier 3 2.65 cu.ft) Measure Impact = (cycles/year * capacity / base EF) – (cycles/year * capacity / measure EF) = (392 * 2.65 / 1.58) – (392 * 2.65 / 4.94) = 447 kWh Demand Impact = Measure Impact * energy/peak factor = 447 kWh * 0.417 = 186.4 W

  29. Non-Weather Sensitive MeasuresResidential Measures • Clothes Dryer1993 National Appliance Energy Conservation Act (NAECA) minimum efficiency used for base technology: EF = 3.01 for electric dryers EF = 2.67 for gas dryersUsed DOE test procedure guidelines for: Drying cycles per year = 416 UEC of 2.33 kWh/cycle for electric (969 kWh/year) UEC of 8.95 kBtu/cycle for gas (37.2 therms/year) Assumed 416 cycles represented Single Family Assumed 250 cycles for Multi-Family (CEC estimate of 60% less use by MF) Energy savings 5% of energy use. This is a carryover from previous 2001 DEER Demand impact based on a energy/peak factor of 0.371. This is carryover from previous 2001 DEER

  30. Non-Weather Sensitive MeasuresResidential Measures • Clothes Dryer – Example (SF electric) Measure Impact = Electric base use * Savings Percentage = 969 kWh * 0.05 = 48 kWh Demand Impact = Measure Impact * energy/peak factor = 48 kWh * 0.371 = 17.8 W

  31. Non-Weather Sensitive MeasuresResidential Measures • DishwasherUsed the Energy Star calculator available on-line at: http://www.energystar.gov Key Input values for the calculator: Base Energy Factor (EF) = 0.46 Measure Energy Factor = 0.58 Annual wash cycle (DOE test procedure) = 215 (assume SF) MF wash cycles (assumed to be ~75% of SF) = 160 • Demand impact based on a energy/peak factor of 0.371. This is carryover from previous 2001 DEER

  32. Non-Weather Sensitive MeasuresResidential Measures • Water HeatingMeasures: High efficiency water heater (electric EF=0.93, gas EF=0.63) Heat pump water heater (EF=2.9) Point of use water heater low flow showerhead (from 2.5 to 2.0 gallons per minute) Pipe wrap Faucet aerators Savings expressed as % of base use Base use varied by utility service area (same method as 2001) • Demand impact based on a energy/peak factor of 0.22. This is carryover from previous 2001 DEER

  33.

  41. Non-Weather Sensitive MeasuresNon-Residential Measures Cooking - Methodology Relied primarily on the PG&E technology briefsFor each of these measures, the energy savings calculation methodology is of the form: Savings = (APECRBase – APECREfficient) * Daily Hours * Days Where: APECR = The Average Production Energy Consumption Rate/hour Daily Hours = 12 Days = 365

  42. Non-Weather Sensitive MeasuresNon-Residential Measures • Copy Machines – three sizes 0-20 copies/minute 21-44 copies/minute over 45 copies/minute Methodology assumptions from Energy Star calculator

  43. Non-Weather Sensitive MeasuresNon-Residential Measures • Vending Machine Controls Characterized in two measures by being installed in: Cold drink vending machines Uncooled snack vending machines Measure savings and characterization from the Pacific Northwest Regional Technical Forum database Methodology assumes operated during off-peak hours, therefore no demand savings

  44. Non-Weather Sensitive MeasuresNon-Residential Measures • Water Heating Savings expressed as % of base use Base use varies by building type. Come from the 1994 DEER study Measures: High efficiency gas water heater (7.1% savings) Point of use water heater (10% savings) Water circulation pump time clock (6% savings)

  45. Non-Weather Sensitive MeasuresNon-Residential Measures • High Efficiency Motors Meet premium efficiency standards established by the Consortium for Energy Efficiency (CEE) Base efficiency meets Energy Policy Act (EPACT) minimum Motor sizes range from 1 HP to 200 HP Motor hours of operation vary by industry sector Motor loading from US DOE Motor Master software Peak demand based on a coincidence factor of 0.75

  46. Non-Weather Sensitive MeasuresNon-Residential Measures • High Efficiency Motors - CalculationEnergy savings (kWh) = (Motor HP / EPACT motor efficiency) * kW/HP * hours of operation * motor loading – (motor HP / premium motor efficiency) * kW/HP * hours of operation * motor loading Peak (kW) = (motor HP * kW/HP * coincidence factor / EPACT motor efficiency) - (motor HP * kW/HP * coincidence factor / premium motor efficiency)
