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 percentage charge on customer utility bills. • The Oregon Public Utility Commission is responsible for overseeing Energy Trust administration of ratepayer funds. • In 2010, paid more than $71.3 million in incentives for efficiency and renewable energy projects.
Why are Savings important to you? Savings that are predicted by your energy model can result in real dollar savings to the owner.
Why are Savings important to you? Other non-energy benefits (NEB’s) that are realized through energy conservation: • Marketability (public image) • Better tenant retention/occupancy rates • Increased occupant comfort • • Environmental benefits (ex. CO reduction) Environmental benefits (ex. CO 2 reduction)
Why are Savings important to ETO? • Savings credited to utilities’ IRP • Used for load forecasting
Why are Savings important to ETO? Energy Efficiency is viewed as a resource equivalent to generation - “The less you consume, the less you have to generate in the first place.”
Effect of Savings to Date – Overall Since 2002, cumulative savings total of: • 254 average megawatts of electricity • 17.8 million annual therms of natural gas • Saved participating customers almost $800 million in bills
2009-2010 Savings – New Buildings “Other” Building types include: •Assembly •Auto Services •Church •Grocery •Gym/Athletic Club •Infrastructure •Laundry/Dry Cleaners •Laundry/Dry Cleaners •Manufacturing •Parking structure/Garage •Religious/Spiritual •Retirement/Assisted Facilities

Cost-effectiveness trends
Measures that typically have not been cost-effective for ETO • Cool Roofs/Eco Roofs
Measures that typically have not been cost-effective for ETO • Insulation (pipe and envelope) beyond code levels • Low-e paint
Measures that typically have not been cost-effective for ETO • Windows (PST shows some cases where it might be cost-effective) • Window Films
Measures that typically have not been cost-effective for ETO • Heat Recovery (incl. drain waste)
Measures that typically have not been cost-effective for ETO • Motors (now under new fed specs) • Ice Storage (Peak reduction) • Behavioral Measures • • Water Heaters in non-restaurants Water Heaters in non-restaurants • Others?
Measures that typically have been cost-effective for ETO • Almost everything related to lighting and lighting controls. • LED’s are the exception as they are still an emerging technology still an emerging technology • Daylighting as well
Measures that typically have been cost-effective for ETO • Demand Control Ventilation • HVAC Controls
Measures that typically have been cost-effective for ETO • Water heating savings measures (showerheads, aerators, etc.)
Measures that typically have been cost-effective for ETO • Refrigeration measures

Measure Analysis and Development
New Measure Analysis Why • Increase demand for product • Drive down product cost over less efficient alternative How • • Request from PMC Request from PMC • Request from market (A/E firms) • Regional support - Opportune time for a coordinated effort • Pilot effort - ex. Emerging tech.

Prioritizing Measures
Measure Types - Prescriptive • Quantifiable and repeatable energy savings across a broad spectrum of building sectors, climates, etc. • Generally preferred by participants and program staff program staff • “Y ou get x dollars per piece of equipment”
Measure Types - Custom • May demonstrate repeatable savings, but varies across installations & building types • Not always widget based • • Climate dependant Climate dependant • Hours of use/occupancy dependant
Example #1-Predictive Savings Tool
Example #2-NB Lighting Tool
New Buildings Program – Typical Project Measure Distribution • 50% of all projects < 25,000 SF • 77% of projects pursue Standard measures • 70% of project savings come from projects that pursue some form of energy modeling

Existing Buildings Custom Project Count by Year
When should projects model?
Modeled projects by building size New Buildings (2009 – 2011) LEED Projects Custom (Modeled) Projects Area (sq.ft) # Area (sq.ft) # 0-30,000 14 0-30,000 1 30-50,000 30-50,000 7 7 30-50,000 2 50-70,000 11 50-70,000 7 > 70,000 35 > 70,000 22 Total 67 Total 32
When should New Buildings projects model? • Projects pursuing LEED certification • Projects > 70,000 SF • Energy intensity of project type (e.g. Grocery vs. grade school) • Pursuing aggressive energy efficiency strategies (e.g. natural ventilation and radiant floors)
