JWG 14 - TC 65/JWG 14

This document defines a set of environmental performance evaluation (EPE) data classes, including their properties.
It is applicable to entire manufacturing facilities or to parts of a manufacturing facility.
This document applies to manufacturing systems including discrete, batch and continuous control, which are defined in IEC 62264-1.
The following are outside the scope of this document:
- syntax of EPE data and data models;
- protocols to exchange EPE data;
- functions that can be enabled by the use of EPE data;
- product life cycle assessment;
- EPE data that are specific to a particular industry sector, manufacturer or machinery;
- acquisition of EPE data.

IEC 63376:2023 specifies the functions and the information flows of industrial Facility Energy Management System (FEMS). Generic functions are defined for the FEMS, to enable upgrading traditional Energy Management System (EMS) from visualization of the status of energy consumption to automation of energy management defining a closer relation with other management and control systems. A generic method to classify the FEMS functions will be explained. The information exchange between the FEMS and other systems such as Manufacturing Operations Management (MOM), Manufacturing Execution System (MES) and Enterprise Resource Planning (ERP) will be outlined.

ISO 20140-5:2017 specifies the types of environmental performance evaluation (EPE) data, including their attributes, which can be used for evaluating the environmental performance of manufacturing systems based on the general principles described in ISO 20140‑1. It also provides recommendations for mapping the EPE data on to information models specified by IEC 62264.
ISO 20140-5:2017 applies to discrete, batch and continuous manufacturing.
ISO 20140-5:2017 is applicable to entire manufacturing facilities and to parts of a manufacturing facility.
ISO 20140-5:2017 specifically excludes from its scope the syntax of the data and information models, the protocols to exchange data models, the functions that can be enabled by data models, and the activities in Level 1 and Level 2.
The scope of ISO 20140-5:2017 also includes indicating the differences among various data and information models and the differences among various representations of environmental performance by actual data.
ISO 20140-5:2017 refers to the semantics of the structured data and information models used by communication protocols. The semantics explain the meaning of the attributes and of the context information.
The following are outside the scope of ISO 20140-5:2017:
- product life cycle assessment;
- EPE data that are specific to a particular industry sector, manufacturer or machinery;
- acquisition of data;
- the activity of data communication.

IEC/TR 62837:2013(E) provides to the technical committees a framework for the development and adaptation of documents in order to improve energy efficiency in manufacturing, process control and industrial facility management.
