EN 16247-4 shall be used in conjunction with and is supplementary to EN 16247-1, Energy audits - Part 1: General requirements. It provides additional requirements to EN 16247-1 and shall be applied simultaneously. The procedures described here apply to the different modes of transport (road, rail, marine and aviation), as well as the different ranges (local to long distance) and what is transported (basically, goods and people). This European Standard specifies the requirements, methodology and deliverables specific to energy audits in the transport sector, every situation in which a displacement is made, no matter who the operator is (a public or private company or whether the operator is exclusively dedicated to transport or not), is also addressed in this document. This European Standard advises on both the optimization of energy within each mode of transport, as well as selecting the best mode of transport in each situation; the conclusions drawn by the energy audit can influence decisions on infrastructure and investment e.g. in teleconferencing or web meetings. Energy audits of buildings and processes associated with transport can be conducted respectively with the EN 16247-2 Buildings and EN 16247-3 Processes e.g. pipelines, depots and escalators/travelators. This part of the standard does not include the infrastructure which supplies energy e.g. the electricity generation of energy for railways.

This European Standard provides a general approach for energy efficiency and energy savings calculations with top-down and bottom-up methods. The general approach is applicable for energy savings in buildings, cars, appliances, industrial processes, etc. This European Standard covers energy consumption in all end-use sectors. The standard does not cover energy supply, e.g. in power stations, as it considers only final energy consumption. This European Standard deals with savings on energy supplied to end-users. Some forms of renewable energy “behind-the-meter” (e.g. from solar water heating panels) reduce supplied energy and therefore can be part of the calculated energy savings. Users of the standard should be aware that this renewable energy behind the meter can also be claimed as energy generated. The standard is meant to be used for ex-post evaluations of realised savings as well as ex-ante evaluations of expected savings. This European Standard provides saving calculations for any period chosen. However, short data series may limit the possible periods over which savings can be calculated. The standard is not intended to be used for calculating energy savings of individual households, companies or other end-users.

This International Standard is applicable to NPP computer-system hardware for systems of Class 1 and 2 (as defined by IEC 61513). The structure of this standard has not changed significantly from the original 1989 issue; however, some issues are now covered by standards which have been issued in the interim (for example, IEC 61513 for system architecture design) and references to new standards have been provided where applicable. The text of the standard has also been modified to reflect developments in computer system hardware design, the use of pre-developed (for example, COTS) hardware and changes in terminology. Computer hardware facilities used for software loading and checking are not considered to form an intrinsic part of a system important to safety and, as such, are outside the scope of this standard. Although the primary aim of this standard is to address aspects of new hardware development, the processes defined within this standard may also be used to guide the assessment and use of pre-developed hardware, such as COTS hardware. Guidance has been provided in the text concerning the interpretation of the requirements of this standard when used for the assessment of such components. In particular, the quality assurance requirements of 4.3, concerning configuration control, apply. Pre-developed components may contain firmware (as defined in 3.8), and, where firmware software is deeply imbedded, and effectively "transparent" to the user, then IEC 60987 should be used to guide the assessment process for such components. An example of where this approach is considered appropriate is in the assessment of modern processors which contain a microcode. Such a code is generally an integral part of the "hardware", and it is therefore appropriate for the processor (including the microcode) to be assessed as an integrated hardware component using this standard. Software which is not firmware, as described above, should be developed or assessed according to the requirements of the relevant software standard (for example, IEC 60880 for Class 1 systems and IEC 62138 for Class 2 systems). I&C components may include programmable logic devices that are given their specific application logic design by the designer of the I&C component, as opposed to the chip manufacturer. Examples of such devices include complex programmable logic devices (CPLD) and field programmable gate arrays (FPGA). While the programmable nature of these devices gives the development processes used for these devices, some of the characteristics of a software development process and the design processes used for such devices, are very similar to those used to design logic circuits implemented with discrete gates and integrated circuit packages. Therefore, the design processes and design verification applied to programmable logic devices should comply with the relevant requirements of this standard (i.e. taking into account the particular features of the design processes of such devices). To the extent that software-based tools are used to support the design processes for programmable logic devices, those software tools should generally follow the guidance provided for software-based development tools in the appropriate software standard, i.e. IEC 60880 (Class 1 systems) or IEC 62138 (Class 2 systems).
