TS EN 16247-3

TS EN 16247-3 defines the requirements, methodology and reporting outputs for an energy audit carried out within a process. It addresses sites where a significant share of energy use comes from production or service processes, and it frames how the audit is organized, analysed and documented. It is applied together with EN 16247-1 and adds process-specific requirements to that general energy audit framework.

What a process-focused energy audit covers

The standard can apply to a single production line, multiple lines, or process-based service areas. It also recognizes areas such as offices, laboratories, research centres, packaging and warehouse sections when they operate under specific conditions linked to the site’s processes. An audit may cover the whole site or only part of it, so the boundary is set according to the actual energy flows and operating structure.

How it relates to EN 16247-1 and other parts

EN 16247-1 provides the general energy audit framework, while this part adds requirements specific to processes. If buildings are included in the audit scope, EN 16247-2 may be applied; if on-site transport is included, EN 16247-4 may be chosen. In general technical terms, this distinction matters because process equipment, support systems and internal logistics can have very different energy profiles, and separating them helps identify improvement opportunities more accurately.

The expected outputs are the organization of the audit, analysis of the data and reporting of the findings. In practical terms, that means a structured review of the main process steps, operating conditions and performance indicators that drive energy use. The standard supports a consistent and comparable approach to energy auditing in process-intensive sites.
