Energy Trust Overview and Measure Development BESF Presentation 6/15/11 Energy Trust Funding & Incentives Funding for incentives is provided by ratepayers of PGE, Pacific Power, NW Natural and Cascade Natural Gas through a
“Other” Building types include:
New Buildings Existing Buildings # projects completed 530 2,500 kWh saved 58,900,000 88,000,000 Therms saved 1,900,000 1,400,000
Therms saved 1,900,000 1,400,000 Total incentives paid ($) $10,350,000 $17,000,000
Measure # Energy Efficiency Measure Name Measure Lifetime (Maximum 70 yrs) Annual Electricity Savings (kWh) Annual Natural Gas Savings (therms) Total Incremental Cost of Measure Total Potential Incentive If Measure is Cost- effective Combined Utility System BCR Combined Societal BCR Simple Customer Payback w/ Incentive (years) 1 Awesome Energy Efficient Measure 5 100,000 4,000 $20,000 $7,000 6.7 2.3 1.2 Efficient Measure 2 Less Awesome Energy Efficient Measure 5 100,000 4,000 $75,000 $0
7.0 3 Less Awesome Energy Efficient Measure (but with longer lasting flavor) 45 100,000 4,000 $75,000 $18,200 13.9 3.4 5.3
Measures Under Analysis Program Sector Measure Name Description Status Building Sector Priority Responsible BE VFD (Variable Frequency Drive) Develop prescriptive VFD measure for BE similar to NBE program Waiting for LMC to initiate blessing memo Office, Retail, School 1 LMC BE Under counter commercial dishwashers Re-do dishwasher analysis to align with upcoming EnergyStar changes. Re-run cost effectiveness test to align with new EnergyStar levels. Foodservice 1 ETO NBM Boiler Pipe insulation Revise old R-8 insulation measures to be more like BE measure. ETO working savings numbers around to keep incentive levels equal. Multi-family 1 ETO BE/NBE Commercial windows Replacement of windows with various U-factor and SHGC combinations for new and existing buildings ICF finalizing PST for both programs Office, Retail, School 2 ICF BE Window Films Tinted window film to lower cooling requirements of commercial buildings Enerlogic has made a product that appears cost-effective for large office
in windows PST, and could find market niche in historic buildings Hospitality/Lodging, schools, grocery, retail, office, hospital 2 LMC niche in historic buildings NBE Controls for EC motors in walk-ins Measure to add a controller or program the EC motor so that fan speed is varied based on refrigerant flow. For a single compressor system, the fan will go to a low speed when compressor stops running. In a multi- plex, a liquid line solenoid valve must be installed so that refrigerant flow can be stopped to the evaporator coil so that refrigerant doesn't go unevaporated through the coil when the fan speed ramps down. PECI is completing a workpaper for the
measure? Grocery 2 PECI BE Case Doors Efficient refrigeration case doors for cases that do not have anti-sweat heaters or controls. PECI looking into grocersmart program for
program, so may not be worth digging further. Grocery 3 LMC BE/NBE Door gaskets for refrg cases Prescriptive measure to replace worn door gaskets for refrigeration cases RTF approved savings. ETO will check to see if cost-effective in our program Grocery 4 ETO BE/NBE LED Parking Lot lighting LED replacement/new lamps for parking lots RTF investigating cost-effectiveness for this measure in their custom program. May adopt similar practices for regional
Retail 5 RTF

Higher incentives for design process activities (e.g. CFD modeling) Emerging technologies, innovative passive designs, and behavioral measures Monitoring and Reporting feedback loop
Design assistance and process checks for smaller, design-build type projects Comprehensive package of Comprehensive package of measures and guide for small commercial buildings; incentives per square foot Green Certification – Earth Advantage Commercial Functional testing requirements
Incentives for systems that promote behavioral changes Incentives for low cost control systems Incentives for optimization software that requires no human interface Energy consultant provides feedback of performance and makes recommendations Energy consultant provides feedback of performance and makes recommendations Motivation for increased participation with Existing Building incentives
