Auditor Briefing Sheet
A one-page cover sheet included with every Large Commercial audit submission that pre-empts the most common scheme RFIs.
The Auditor Briefing Sheet is a one-page document EnergyAE includes at the top of every Large Commercial audit submission. Its purpose is to make the audit pack self-explanatory to a non-technical ESC/IPART auditor: brand and entity relationships are stated up front, naming inconsistencies are explained, and any non-standard modelling inputs are flagged with reasoning.
The briefing sheet is a direct outcome of the AE574 debrief — the “auditor lens” principle articulated during that project: “audit files must be self-explanatory for a non-technical auditor; the easier we make it for them, the fewer RFIs, the faster the approval.”

Contents
The briefing sheet is intentionally short — one page. It is read first by the auditor and answers questions they would otherwise raise as RFIs.
1. Brand and entity map
A small table:
| Role | Name | Notes |
|---|---|---|
| Registered brand on the scheme | {Hunt Heating Commercial Hot Water} | The brand under which the system is sold and registered |
| Legal entity (applicant) | {HydroHeat Supplies Pty Ltd} | ABN: {12 345 678 901}; registered address: {11 Fiveways Blvd, Keysborough, VIC} |
| Heat pump manufacturer | {Mayekawa Australia} | OEM. Address on EN 14511 report: {Kob Drive, Braeside, VIC} |
| Tank manufacturer | {Aquaplus} | Tank component supplier |
| Distributor / sales brand | {Hunt Heating} | Public-facing distribution brand |
This single table pre-empts the AE574-style auditor RFI on why the operation manual says “Mayekawa”, the install manual says “Aquaplus”, and the registered brand is “Hunt Heating”.
2. Document naming rationale
A short paragraph explaining each document’s authorship:
The EN 14511 test report is issued to the heat pump manufacturer ({Mayekawa}) as the testing party. The application is being made by the distributor ({HydroHeat Supplies}) under the registered brand ({Hunt Heating Commercial Hot Water}). The included Authorisation Letter from {Mayekawa} authorises {HydroHeat Supplies} to use the EN 14511 results for this application. The installation manual is co-branded as it is intended for end-user reference. The operation manual is the heat pump manufacturer’s standard document and references {Mayekawa}.
3. Model name map
Every model name as it appears on each document, plus the model name being applied for. Catches the “why does the test report say X but the application says Y” RFI:
| Document | Model name as printed | Notes |
|---|---|---|
| EN 14511 test report | HE-HWA-2HTC | Manufacturer’s model |
| AS/NZS 4692 report | AQP-1000 | Tank model |
| Installation manual | HHCHW-CO2-1000-HE | Applicant’s registered model code |
| Application register | HHCHW-CO2-1000-HE | As above |
| TRNSYS files | HHCHW_CO2_1000 | TRNSYS naming convention (no special chars) |
A Manufacturer Declaration explaining any name differences is included in the audit pack.
4. Tank coverage statement
If the application includes multiple tank variants:
The AS/NZS 4692.1 heat loss report covers the {EC} variant. The included Equivalence Declaration confirms that the {SC} variant shares identical heat loss characteristics.
5. Non-standard modelling inputs
If any aspect of the modelling deviates from defaults, explain:
Modelling uses {a 10°C deadband on the boost element, rather than the typical 5°C}, because {the control declaration confirms this is the factory default setting on the as-shipped product}.
The pump performance is represented in TRNSYS using the polynomial coefficients c0={0.123} and c1={0.456}, derived from the pump test report points {P1 = (40 L/min, 110 W), P2 = (100 L/min, 280 W)}. The fitted polynomial reproduces the test points within {2%}. See the Pump Performance Plot in the audit pack.
6. Performance map coverage
EN 14511 testing covered the following conditions: air dry bulb {2°C, 7°C, 12°C, 19°C, 38°C}; wet bulb pairs as per the report; water inlet {10°C, 30°C, 50°C}. AS/NZS 4234 annual simulation hours fall within this matrix (or close enough that extrapolation is bounded). See the Performance Map Coverage figure in the audit pack.

When the briefing sheet is mandatory
Always. Even for the simplest single-product follow-on submissions, the briefing sheet costs 30 minutes to produce and reduces RFI risk materially.
