Pre-Screening Interview Questions to Ask an Energy Auditor

Last updated on

An audit report full of recommendations nobody implements has saved nothing. These questions separate auditors whose measures were installed and paid back from those who produced a thorough survey.

TL;DR, what to screen for

The best pre-screening questions for an energy auditor test four things: savings clients actually achieved rather than recommendations issued, whether measurement supports the figures or they come from a table, whether recommendations are prioritised by payback the client can afford, and whether anyone verified the saving afterwards. Ask what was actually installed.

  • Savings achieved
  • Measured not estimated
  • Payback they can afford
  • Verified afterwards

Why pre-screen energy auditors before the site interview

Audits are commissioned more often than measures are installed, usually because the report lists thirty recommendations in no useful order and the client cannot fund the first three. Auditors who get results prioritise by payback within the client's budget and follow up to check the saving happened. The other thing that separates people is whether the figures come from measurement or from a standard table. A short screen asks both.

What actually matters when screening Energy Auditor candidates

  1. 01

    Technical depth

    Check command of ASHRAE Level I to III audit scope, ASHRAE 211 procedures, weather-normalized utility baselining, and tools like eQUEST, EnergyPlus, RETScreen, or IPMVP-based M and V.

  2. 02

    Work that shipped

    Ask for specific buildings audited: floor area, sector, ECMs recommended, verified kWh or therm savings, simple payback figures, and which measures the owner actually funded.

  3. 03

    Diagnosis under uncertainty

    Probe how they resolve conflicting evidence: blower door and duct blaster results, FLIR imagery, combustion analyzer readings, submetering data, or bills that contradict occupant reports.

  4. 04

    Working across the org

    Assess how they work with facility engineers, finance staff on payback thresholds, and utility rebate program administrators or contractors bidding the recommended scope.

Savings achieved

3 questions
  1. 01What experience do you have conducting energy audits?

    Listen for

    Number and type of audits with building sizes named, and what proportion led to installed measures.

    Audit counts quoted with no implementation outcome, or building types left undescribed.

  2. 02Do you have experience with residential, commercial or industrial audits?

    Listen for

    The methodological differences named, with process energy treated as a distinct specialism where relevant.

    All types claimed with no distinction, or industrial experience that turns out to be a large office.

  3. 03Can you explain the process you follow from initial contact to final reporting?

    Listen for

    A structured process including data gathering before the site visit, so the survey is targeted.

    Surveys conducted with no prior consumption data, or reports produced from a single walk-through.

Measured not estimated

4 questions
  1. 04Can you describe the methodologies you use during your audits?

    Listen for

    A recognised audit level named with the depth of measurement it implies, matched to what the client needs.

    Methodology described as inspection, or the same depth applied regardless of the decision at stake.

  2. 05What tools and software do you use when performing an audit?

    Listen for

    Measurement equipment used on site, such as loggers or thermal imaging, alongside modelling software.

    Audits performed with no instrumentation, or findings produced entirely from a software model.

  3. 06How do you ensure the accuracy and reliability of your findings?

    Listen for

    Estimates reconciled against actual consumption from billing data, with any unexplained difference investigated rather than left standing.

    Calculated savings never checked against billed consumption, or discrepancies left unexplained.

  4. 07What is your approach to assessing heating and cooling systems during an audit?

    Listen for

    Control settings and operating schedules examined alongside equipment, since controls often deliver the cheapest saving.

    Assessment limited to equipment efficiency ratings, or controls and schedules never examined.

Payback they can afford

3 questions
  1. 08Can you provide examples of energy savings you have helped clients achieve?

    Listen for

    Savings measured after installation with the baseline stated, not the figure that was projected.

    Projected savings quoted as achieved, or no client where the outcome was verified.

  2. 09How do you prioritise recommendations in your audit reports?

    Listen for

    Ordering by payback with the no-cost and low-cost measures first, so something can start immediately.

    Recommendations listed by system rather than by return, or capital measures presented first.

  3. 10What measures do you use to determine the effectiveness of your recommendations?

    Listen for

    Consumption compared before and after with weather and occupancy normalised, rather than raw bill comparison.

    Effectiveness assessed from unadjusted bills, or no follow-up measurement at all.

Verified afterwards

2 questions
  1. 11How do you handle projects where clients have limited budgets for implementation?

    Listen for

    A staged plan where early savings fund later measures, with the cheapest interventions identified clearly.

    Full recommendation lists issued regardless of budget, or capital measures pushed on clients who cannot fund them.

  2. 12Do you offer post-audit support or follow-up services?

    Listen for

    Follow-up as standard practice to check what was installed and whether the saving materialised.

    Involvement ending at report delivery, or no knowledge of what clients implemented.

How to score responses

Score every candidate on the same four criteria immediately after the screen. At this stage you are shortlisting for panel interviews, not making the final call.

  1. Technical depth

    35%

    5Names audit level scope precisely, explains degree-day normalization, and holds CEM, CEA, or CMVP with modelling work they built themselves.

  2. Work that shipped

    30%

    5Cites named audit reports with quantified savings, implemented measures, and post-retrofit verification rather than a list of recommendations only.

  3. Diagnosis under uncertainty

    20%

    5Walks through a puzzling consumption anomaly, the instrument data gathered, and how the true cause (controls, schedule, envelope) was isolated.

  4. Working across the org

    15%

    5Describes translating audit findings into capital requests, defending assumptions to CFOs, and shepherding incentive applications through utility review.

Thirty recommendations in no useful order and a client who can fund three of them saves nothing. A one-way video screen asks what was actually installed.

Screening FAQ

Process basics

How long should a pre-screening round for an energy auditor take?

Ten to fifteen minutes across eight to ten questions, answered async. Enough to establish the buildings they audited, test their measurement method, and hear what clients actually implemented.

How much does building type matter?

Considerably. Residential, commercial and industrial audits use different methods and find different opportunities, and industrial process energy is a specialism of its own. Ask which they have actually done.

Evaluating answers

What is the strongest signal when screening this role?

Measures that were installed. Auditors who get implementation prioritise by payback and know what clients did. Anyone who reports on recommendations issued has produced surveys rather than savings.

How do I judge their measurement?

Ask where the savings figures came from. Real answers involve metering, logging or bill analysis over a period. Anyone quoting savings from a standard table has estimated rather than measured.
