Background October, 2010 – January, 2012: Small/Rural Utility

Technical Support Needs Study – Conducted by Ecotope w/ RTF S/R Subcommittee

Final report included RTF-specific recommendations (from Ecotope and from utilities)

January, 2012: RTF reviewed RTF-specific recommendations and RTF-staff response

Designated the S/R subcommittee to prioritize recommendations and develop work plan

May, 2012: SRR committee selected PECI to mine regional schools audit programs and develop measure recommendations

Measure Proposal CriteriaMeasure Proposal

1. Specification

2. Preliminary description of savings estimation procedure

3. Estimate of total achievable regional savings potential

4. Estimates of EUL and cost

5. Category: Planning, Small Saver, Provisional, Operative

- RTF Guidelines

Measure Qualities1. Deemed and easy to implement 2. Achieve high savings3. Don’t change very often

- S/R Technical Support Needs Study

Small/Rural Utility UES Measure Design Checklist

The measure applies to small and rural utilities

The measure requires minimal utility oversight

The measure requires minimal technical support from the utility

Small/Rural utilities are likely to have delivery infrastructure

Definition is straightforward Identification of compliance with the

measure is straightforward

Analysis: Data• ODOE Cool Schools Program

– Energy audits of 500 school facilities in Oregon• 979 buildings• Just over 8000 measures identified, about 50% in small/rural

utility territory

• Additional data from– 13 MT school audits– 62 ID school audits

Measure Proposals

Measures Savings Estimation

Interior Lighting

(1) Low wattage T8 lamp(2-5) Delamp + high performance T8(6) Generic high efficiency fixture

The difference in baseline and efficient case Lamp Wattage is multiplied by the Operating Hours. Interior only: The Lighting Savings is multiplied by the interactive heating factor.

Exterior Lighting

(1) High efficiency pole/arm-mounted fixture with photocell

(2) High efficiency wall/ceiling-mounted fixture with photocell

Weatherization

(1) Attic insulation(2) Wall insulation(3) Floor insulation(4) Reduce infiltration

Create and calibrate baseline building prototypes. Simulate baseline and efficient scenarios and savings are the difference

Programmable thermostat

Shared Characteristics- Deemed- Small savers

Measure Proposals

Measures Savings Estimation

Demand control ventilation (gym or auditorium)

(1) DCV with VFD, packaged heat pump

(2) DCV with VFD, packaged gas furnace

(3) DCV on packaged heat pump (no VFD)

Create and calibrate baseline building prototypes. Simulate baseline and efficient scenarios and savings are the difference

Domestic hot water pump – time clock

Faucet aerator Engineering calculation using baseline and efficient case flow rates.

Vending machine controller Statistical analysis of EM&V results

Next Steps• SRR subcommittee will review final work

products– Make recommendations for further development of

measure workbooks

• Under 2013 budget, SRR subcommittee will select contractor to finalize workbooks

• Bring back to RTF in 2013 for approval once recommended by SRR subcommittee
