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

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 2

Measure History Northwest ENERGY STAR (NWESH) homes program active in region since at least – 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.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 3

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

UES Analysis Summary

Measure Classification 9

Measure Identifiers 10

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

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 12

Predicted 2011 Savings Relative to 2008 ORSC presented at RTF 11/2/ *More savings means less energy use in 2011
