Evidence to retain

InputEvidence required
Heat-loss inputUse a site survey or documented calculation for the actual equipment boundary.
Operating dataRecord the annual hours and the evidence used.
Conversion factorRecord the publication, reporting year, activity unit and fuel basis.
ReviewHave the result checked before it is used in a statutory or contractual report.

For UK company reporting, use the applicable UK Government greenhouse gas conversion factors. Check the reporting year and factor basis.

Inzonex removable modular insulation on industrial equipment
Equipment heat loss

Measure exposed hot surfaces

Use measured surface area, temperature and operating hours to calculate heat loss from boilers, kilns, heat exchangers, valves and pipework. Inzonex supplies removable modular insulation for equipment that requires maintenance access.

  • Design target: surface temperature at or below 45 °C, subject to the application and design review
  • Claimed heat-loss reduction: up to 96%, subject to the measured boundary and insulation specification
  • Removable construction for inspection and maintenance access
  • Calculation record available for the selected equipment and operating conditions

Do not add a calculated reduction to an emissions report until the reporting boundary, factor, implementation date and verification method have been approved.

03

Use of the result

Use the record as working evidence. Do not describe the result as verified unless an appropriate review or assurance process has been completed.

Questions

Questions on this topic

Is this an official certificate?
No. It is a draft calculation record and does not independently verify the inputs.
Where should the heat-loss input come from?
Use a site survey or a documented calculation for the actual equipment boundary and operating conditions.
Can this result be used directly for CBAM?
No. CBAM embedded-emissions calculations must follow the applicable EU method and production boundary.
