14
Participant Players and Roles
15
Participant Players and Roles
  • OOE
  • ESDs
  • School Districts
  • Auditors
  • Commissioning Agents

16
OOE Role
  • Program oversight for consistency statewide
  • Verify eligibility of facilities annually
  • Issuing RFPs
  • Auditors
  • Commissioning
  • Update qualified auditor list
  • Audit waiver approval
  • Data collection and database management
  • Training programs for ESD and SDs

17
OOE Role
  • Quality control of audits
  • To compare data gathered from on-site survey to
    report assumptions, calculations, and
    recommendations
  • Review audit report
  • Check calculation methodology
  • Check if non-energy issues are addressed or
    ignored (i.e., IAQ)
  • Site visit
  • QC review for each vendor at each audit level
    plus random reviews

18
OOE Role
  • General technical assistance
  • Specific technical assistance on request
  • Reporting
  • Annual - PUC
  • Biennial - legislature
  • Quarterly - ESD and/or SD
  • Coordinate with the Energy Trust of Oregon

19
ESD Role
  • Verify eligibility of facilities annually
  • Receipt of public purpose funds
  • Reimburse eligible SD costs
  • Coordinate with Oregon Office of Energy
  • Provide assistance (in some cases)
  • Special cases - WESD, Beaverton SD

20
Clarification of WESD and OOE roles
  • WESD services
  • Turnkey services
  • Review of all audits (no on site reviews)
  • Their needs/requirements may differ from OOE
  • Any communications from WESD from an OOE employee
    should be regarded as WESD point-of-view
  • OOE services to WESD
  • Sub-contractor for audit reviews and general
    program development

21
SB1149/ESD Coverage
22
School District Role
  • Verify eligibility of facilities annually
  • Annual reporting of EUI data (into SID)
  • Hire auditors
  • Obtain additional financing BETC partners
  • Prioritize EEMs
  • Implement EEMs
  • Report completed measures to SID

23
Auditor Role
  • Audits
  • Specifications
  • Project verification
  • SD or ESD dependent
  • (e.g., EUI data entry)
  • Billing/invoice per school basis
  • Marketing (optional)

24
Commissioning Agent Role
  • Design review
  • Punchlist/functional testing
  • Marketing (optional)
  • RFP is currently on OOE website

25
Audit Reports and Expectations
26
Audit Format
  • Audits must be stand alone
  • Audits are NOT a design document
  • If engineering is necessary, say so (and include
    cost in analysis)
  • But, provide some basic information (e.g., new
    boiler should be X HP)

27
Audit Format
  • OOE Format _at_ www.energy.state.or.us
  • Dont have to download to use
  • All information in format is required
  • Should be similar in nature and organization
  • Minimum should include
  • EEM Summary
  • Individual EEM/OMs
  • Clear calculations

28
Calculations
  • OOE must be able to follow
  • All calculations must be presented
  • State assumptions appropriately
  • If using rules of thumb, state them
  • Based on my experience is not an acceptable
    thumb rule

29
Calculations
  • Audit Level 1
  • Nomographs
  • Appropriate rules of thumb
  • Simple spreadsheets
  • Interactive effects exist between specific EEMs
  • Audit Level 2
  • Bin analysis
  • Detailed spreadsheets
  • More sophisticated calculations
  • Should include interactive effects

30
Calculations
  • Audit Level 3
  • Complex spreadsheets
  • Must include hourly analysis
  • Must include interactive effects

31
Disclosure within report
  • Engineering design is required before
    implementing this EEM
  • May include some warning (e.g., water heater must
    be sized to satisfy athletic shower load)
  • If noise levels will change (increase), say so in
    the report
  • If energy use will increase, say so
  • Point out indoor air quality issues

32
Disclosure (cont)
  • Identify any safety issues
  • Include identification of known or potential PCB
    ballasts
  • Life of existing equipment
  • Justify your statements
  • Need more than is beyond its useful life

33
OM Savings
  • OM savings are not real, unless
  • School must SEE any claimed savings
  • Contracted service that can be cancelled
  • In house savings would require that school reduce
    staff as a result of the measure

34
Hours of Operation
  • Question hours provided by schools
  • Hours often include more than school
  • OOE Defaults
  • Elementary - 2,000 hours
  • Middle - 2,200 hours
  • High School - 3,200 hours

35
Lighting
  • Use IES for guidance
  • Recognize the school staff does not like underlit
    areas
  • Lockers in halls need light
  • Many areas are used by students for other than
    traditional purposes (hallways are study areas)
  • OOE Recommends
  • 50 footcandles for general classrooms
  • Must measure fc for all audit levels

36
Project Costs
  • Requires justification
  • Based on my experience is not an acceptable
    method of cost estimating
  • Identify your source
  • R.S. Means
  • Estimating Software
  • Recent similar project (but include a brief
    description of the similar project with dates)
  • Contractor estimates

37
Energy Efficiency Measures (EEMs)
  • OOE has provided a list in SID
  • We have tried to develop a complete list
  • Cant anticipate everything
  • If we missed a common EEM, notify OOE. We can
    add to the list
  • If a single use item, add as Other in SID
  • Include a list of rejected EEMs, if appropriate

38
Rates
  • Report should include the rate schedule that the
    school is using (or will use in the near future)
  • Use the appropriate cost in calculations
  • Not the average cost

39
Things OOE will be watching
  • Existing fc levels must be provided
  • Lighting changes
  • If you remove lamps/delamp, you must include
    appropriate information on
  • Proposed lumen levels
  • If you are changing technology
  • Provide adequate documentation to explain the new
    technology

40
Generic Red Flags
  • Any EEM with odd paybacks
  • Inappropriate EEMs (new boiler rather than stack
    damper)
  • Inappropriate design temperatures
  • Inappropriate weather data (see OOE website for
    weather data)
  • Claiming savings based on manufacturers savings
    estimates
  • Baseline adjustments
  • Dangling EEMs

41
OOE Attention List
  • Existing lumen levels
  • Boiler combustion efficiency test (mandatory for
    level II and III audits)
  • Heating oil consumption (minimum 2 years)
  • Hours of operation
  • Condition/operation of outside air dampers
  • Questionable assumptions
  • Unjustified delamping

42
Termination of Agreement to Agree
  • Negligence
  • Non-professionalism
  • Not fixing audit errors
  • Other reasons as they occur
  • Non-responsive
  • Repeating same errors

43
Requiring further evaluation
  • Acceptable statements of EEMs requiring further
    evaluation include
  • In general EEMs that are beyond the scope of the
    level of audit being performed
  • Level 1 audit which includes evaluation of
    chiller controls
  • Complex control strategies
  • Others as applicable

44
Not requiring further evaluation
  • EEMs requiring further evaluation should not
    include
  • Lighting
  • Timeclocks / simple DDC

45
EEM Requirements
  • Must reduce energy use
  • Fuel switching can be done if total energy use is
    reduced (saves BTUs)
  • Projects (set of EEMs at a school) must have ?
    10 year simple payback
  • In audit report, list EEMs with gt10 year simple
    payback

46
Engineering economics
  • Simple payback is measure of success
  • Life cycle cost not required, but can be
    beneficial
  • Life of new equipment must be stated
  • District cannot buy down projects

47
Feedback from Schools
  • Not enough OMs are identified
  • Level I audit is not sufficient (not enough
    information)

48
Feedback from OOE
  • Red flags and disclosures are ignored
  • E.g., savings based on my experience are not
    allowed
  • Need existing fc levels
  • Do not include costs of security system features
    in cost of DDC system
  • Please enter audits into SID when finalized by
    SD or ESD

49
Your Turn
  • Questions
  • Feedback
  • Concerns
