New Measure Submission Process

Regional Technical Forum January 22nd, 2014

New Measures Submitted via Online Proposal Form

Weblink: http://rtf.nwcouncil.org/proposalform

Process for Reviewing

Process for Reviewing

• Staff recommends likely path of measure• Brings before RTF for questioning, and feedback• Seeks approval to spend staff resources developing

• If resources are approved, staff works with proposer and interested parties• Staff may further scope measure for feasibility• Important that sponsor of measure is involved in

development process

• Staff will bring before RTF once complete• Run through R&E subcommittee if research needed

What You Are Being Asked Today• Staff has received 3 new measure proposals in 2013• Developed checklists and probable development

categories• Posted to RTF agenda page

• Need RTF to decide that staff should pursue measure development• Alternately, could ask for more research/information

• Also provide feedback on proposed process• Future measure presentations should be relatively quick

What Our Work Plan Says• Capture new measure proposals in Work Plan• 5 UES measures were expected from BPA• 3 UES measures budgeted as placeholders• 2 Standard Protocol placeholders

• If more are developed, would need to reallocate resources from other areas• Any proposal from an “outside” entity takes

more staff time• Standard Protocols much bigger lift for RTF in general

Coil Cleaning – Preliminary Staff Review Presentation

New Measure Proposal January 22nd, 2014

Measure background

• Measure Name: Coil Cleaning• Likely Measure Type: Standard Protocol• Likely Measure Category: Provisional• Measure Sector: Commercial• End-Use: HVAC• Proposing Party: Nalco Company

(manufacturer of coil cleaning products)

• Interested Parties: BC Hydro, Seattle City Light, PSE, Avista

Measure Definition and Specifications• HVAC coils, from large roof-top units to small in-

room PTAC units, are cleaned using a pressurized (100-500 psi), proprietary cleaning agent• Product claims to both help HVAC systems operate

more efficiently and reduce odors related to dirty HVAC equipment• Product also claims that regular coil cleaning can

extend HVAC equipment life

Measure Supporting Data• A demonstration M&V project performed on a

hospital VAV system in BC Hydro territory showed savings of about 12% of total fan energy and 22% of total chiller electrical energy – or about 275,000 kWh/yr1

• ASHRAE has published a paper verifying the energy savings potential of coil cleaning2

1 Hanada, Vince. Coil Cleaning and Filter Change Demo Project: Fraser Health Authority, Eagle Ridge Hospital. BC Hydro, October 2011.2 Montgomery, Ross and Robert Baker. Study Verifies Coil Cleaning Saves Energy. Published in ASHRAE Journal Vol. 48, Nov. 2006.

Staff Assessment

• Staff believes that this measure could be developed as a Provisional Standard Protocol• The proposal is for a measure that is not already defined

in the existing RTF database• This measure has not been previously “de-bunked” by

the RTF or others• Measure is applicable in the region• Nalco (the proposer) has provided energy savings

calculations which could serve as the basis of a Provisional Standard Protocol calculator

Staff Assessment (continued)• Staff questions/concerns to the RTF• Bundling – Coil cleaning can be combined with other

HVAC O&M practices simultaneously (e.g. filter change/upgrade as in BC Hydro study)• Can savings for coil cleaning be computed separately from

other measures or O&M practices in a reliable manner?• EUL – No persistence studies found to support this

• RTF would need to estimate how long the savings persist• Baseline – Can data be collected to suggest what level

(or quality) of coil cleaning is already being done?

RTF Proposed Motion:

“I _________ move that the RTF:

(Pick one)

1. allocate staff resources towards developing a Coil Cleaning Standard Protocol measure, or

2. not allocate staff resources to developing a Coil Cleaning Standard Protocol measure.”

Refrigeration Cycle Optimization – Preliminary Staff Review Presentation

New Measure Proposal January 22nd, 2014

Measure background

• Measure Name: Refrigeration Cycle Optimization

• Likely Measure Type: Standard Protocol• Likely Measure Category: Provisional• Measure Sector: Residential &

Commercial• End-Use: HVAC & Refrigeration• Proposing Party: Emerging Energy

Solutions (ClimaCheck)• Interested Party: ETO?

Measure Definition and Specifications• Instruments make it possible to attain system

performance data to optimize refrigeration and cooling system operation

• ClimaCheck manufactures two types of equipment that meet this specification:• Portable Installation: Portable ClimaCheck can be

connected to a desired system; it will provide equipment performance documentation within 30 minutes of connection.• Fixed Installation: Fixed ClimaCheck equipment will

provide continuous monitoring of equipment performance and energy consumption. Immediate feedback provided if maintenance required.

Sample Equipment

Measure Supporting Data• The ClimaCheck system is currently installed in:

• Refrigeration systems in large grocery stores in Vancouver, Toronto, and Denver (planned)

• Cooling systems for Virgin Atlantic (35 locations), EDF Energy • Pilot study with NREL conducted at a grocery rack at SuperValue

(Maryland). SuperValue went bankrupt, none of the findings were actualized as savings

• Working with NREL to set up 2 pilot installations

• Initial estimates of energy saved by this measure for large commercial refrigeration systems in an ETO installation are 6%- 10 %• For the ETO installation, savings are predicted to be ~85,000

kWh/ year

Staff Assessment

• Staff believes that this measure could be developed as a Standard Protocol• The new measure proposal is complete with energy

savings information from case studies• The proposal is for a measure that is not already defined

in the existing RTF database• Proposal doesn't address a measure that has already

been de-bunked by others (or the RTF)• Measure is applicable in the region

RTF Proposed Motion:

“I _________ move that the RTF:

(Pick one)

1. allocate staff resources towards developing a Refrigeration Cycle Optimization Standard Protocol measure, or

2. not allocate staff resources to developing a Refrigeration Cycle Optimization Standard Protocol measure.”

Thermostatic Shower Restriction Valve –

Preliminary Staff Review PresentationNew Measure Proposal

January 22nd, 2014

Measure background

• Measure Name: Thermostatic Shower Restriction Valve

• Likely Measure Type: UES• Likely Measure Category: Provisional• Measure Sector: Residential• End-Use: Hot Water• Proposing Party: ShowerStart, LLC• Interested Party: Southern California

Gas, Ucons

Measure Definition and Specifications• Device works by slowing the water down to a

trickle once the hot water reaches the valve, thus saving the hot water that would be wasted down the drain when the shower is not being attended.

• In CA this measure is bundled with low flow showerheads.

Measure Supporting Data• The ShowerStart system is currently approved by CA Energy

Division and offered in California and by Puget Sound Energy (PSE).

• This measure is also being introduced in EE programs in California, Arizona, Florida, Georgia, Texas, Michigan, Colorado, and New York (As per conversation with ShowerStart).

• Measure savings dependent on time a shower is left unused by user; this parameter is speculative and no actual field measurements have been conducted yet. ShowerStart, LLC is planning to conduct research with utilities to better understand this parameter.

• Estimates of energy saved by this measure approved by CA Energy Division are 45 kWh for SF and 50 kWh for MF

Staff Assessment

• Staff believes that this measure could be developed as a Provisional UES measure• The proposal is for a measure that is not already defined

in the existing RTF database• Proposal doesn't address a measure that has already

been de-bunked by others (or the RTF)• Measure is applicable in the region• Research shows that ShowerStart is usually bundled

with low flow showerheads for ease of implementation• Data to construct a Proven UES measure does not exist

RTF Proposed Motion:

“I _________ move that the RTF:

(Pick one)

1. allocate staff resources towards developing a Thermostatic Shower Restriction Valve UES measure, or

2. not allocate staff resources to developing a Thermostatic Shower Restriction Valve UES measure.”
