process for reviewing1
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
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
What Our Work Plan Says
  • Capture new measure proposals in Work Plan
    • 5 UES measures were expected from BPA
    • 3UES 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

New Measure Proposal

January 22nd, 2014

measure background
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
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
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 Assessment
  • Staff believesthat this measure couldbe 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 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
RTF Proposed Motion:

“I _________ move that the RTF:

(Pick one)

  • allocate staff resources towards developing a Coil Cleaning Standard Protocol measure, or
  • not allocate staff resources to developing a Coil Cleaning Standard Protocol measure.”
refrigeration cycle optimization preliminary staff review presentation

Refrigeration Cycle Optimization – Preliminary Staff Review Presentation

New Measure Proposal

January 22nd, 2014

measure background1
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 specifications1
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.
measure supporting data1
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 assessment1
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 motion1
RTF Proposed Motion:

“I _________ move that the RTF:

(Pick one)

  • allocate staff resources towards developing a Refrigeration Cycle Optimization Standard Protocol measure, or
  • not allocate staff resources to developing a Refrigeration Cycle Optimization Standard Protocol measure.”

New Measure Proposal

January 22nd, 2014

measure background2
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 specifications2
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 data2
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 assessment2
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 ProvenUES measure does not exist
rtf proposed motion2
