Confirm the standard version

SBTi states that version 1.3.1 remains the framework for target validation during 2026. Validation under version 2.0 starts in 2027.

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

View modular insulation Prepare a heat-loss study

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

Reconcile the inventory

Link activity data, factors, exclusions, base year, target boundary and progress figures to controlled records.

Evidence completed action

For an efficiency project, retain the equipment boundary, method, operating data, conversion factor and review status. Do not apply a general reduction percentage.
