  1. Northwest ENERGY STAR Specification for Oregon 2012 Active UES Proposal Presentation to the Regional Technical Forum November 1, 2011 Ben Larson, Ecotope and David Hetherington, Fluid Market Strategies

  2. Measure Summary • Measure name: Energy Star Homes OR 2012 • Measure sponsor: NEEA • Measure description: • Construction of and installation of lighting and appliances in new, single family residences in accordance with the Northwest ENERGY STAR Homes 2012 Oregon Specification. Applies to houses built in OR only. • Measure type: UES • Requesting Status: Approved • Change in measure status: Yes (proposed  active) • Change in measure savings: No • Change in measure cost effectiveness: No • Other or follow-on work for RTF: No

  3. Measure History • Northwest ENERGY STAR (NWESH) homes program active in region since at least 2004. • Initial program had one, regional spec • In 2008, a targeted spec was developed for Oregon in response to the improved state energy code • Presented to RTF on February 5, 2008. • Savings approved at that time • OR spec revised again in 2011 in response to further code changes • Measure Developers: • Specs: NEEA, Fluid Market Strategies, Ecotope • Workbook: Ecotope

  4. Measure Background • Introduction and Process • Need for Specification Change • Oregon 2011 Code Change • EPA ENERGY STAR Specification Change • Specification Development • Regional Alignment

  5. Northwest ENERGY STAR Homes in Oregon

  6. Proposed NWESH Spec for Oregon

  7. Proposed Northwest ENERGY STAR Specification for Oregon

  8. UES Analysis Summary

  9. Measure Classification

  10. Measure Identifiers

  11. Constant Parameters • NWESH is a big package of measures - few constant parameters besides house dimensions and climates.

  12. Code Baseline • Code requires 2 add’l measures for compliance • No state-wide survey of measures but OR BCD will be building a database of code compliance starting this year • Base case in this analysis uses HVAC equip upgrade and house tightness/duct sealing measures • Heat Pump / Furnace upgrade highly probably (RTF already set base HP efficiency at HSPF 8.5) • Analysis from 2 Nov 2010 RTF shows range of energy use for different measure combinations: • HVAC upgrade + sealing is a mid-range user for all HVAC upgrade combos

  13. Predicted 2011 Savings Relative to 2008 ORSCpresented at RTF 11/2/2010 *More savings means less energy use in 2011

  14. UES Estimation Method: BOP1 Heat, Cool, Lights

  15. UES Estimation Method: BOP1 DHW, Ventilation

  16. UES Estimation Method: BOP2 Heat, Cool, Lights

  17. UES Estimation Method: BOP2 DHW, Ventilation

  18. Measure Cost Summary

  19. Measure Cost Detail (1)

  20. Measure Cost Detail (2)

  21. Measure Life & Sunset Criteria • Measure categories: • Shell: 70 years • Domestic Hot Water: 15 years • Lights: 7.6 years • Sunset Criteria: Measure shall sunset upon adoption of a new residential energy code in Oregon.

  22. Results

  23. BOP1: Gas Furnace w/ CAC Savings

  24. BOP1: Gas Furnace w/o CAC Savings

  25. BOP1: Heat Pump Savings

  26. BOP2: Zonal Electric Savings

  27. Cost Effectiveness: B/C Ratio’s

  28. Checklist: Guidelines

  29. Motion for Approval “I _________ move that the RTF approve the UES for Energy Star Homes Oregon 2012 with active status which will sunset upon adoption of a new residential energy code in Oregon.”
