Use a measured equipment boundary, verified operating inputs and the conversion factor required for the reporting year.
Insulation can reduce Scope 1 emissions when it reduces on-site combustion of a fuel that is included in the organisation's Scope 1 boundary. It does not automatically create a reportable saving.
Calculation sequence
Energy saving = heat-loss reduction × operating hours ÷ system efficiency. Emissions saving = energy saving × the approved conversion factor.
Retain enough evidence for a reviewer to reproduce the result.
| Record | Minimum content |
|---|---|
| Equipment boundary | Asset identifiers and the surfaces included |
| Baseline | Surface area, temperature, ambient conditions and operating hours |
| Intervention | Insulation material, thickness, coverage and installation date |
| Calculation | Method, system efficiency, fuel factor and reporting period |
| Verification | Post-installation inspection or measurement and reviewer approval |
Use the Inzonex heat-loss calculators for the equipment calculation and the calculation record to retain the reporting inputs.
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.
Do not add a calculated reduction to an emissions report until the reporting boundary, factor, implementation date and verification method have been approved.
Use the reporting method that applies to the organisation.
This page explains the calculation structure. It does not determine an organisation's reporting boundary or provide assurance.
