Last week we gave you an overview of ISO 50001. As a refresher, ISO 50001 is an Energy Management System certificate that provides a framework for establishing best practice energy management to organisations. The standard enables organisations to establish a framework necessary to improve energy performance, including energy efficiency, use, and consumption.
Now we'll give you an overview of the other ISO energy related certifications and how they could apply to your business.
ISO 50002 uses the terminology of ISO 50001 and describes a best practice framework to identify energy saving opportunities. Users of the standard follow standardised steps for identifying opportunities for improvement.
Using this standard, organisations implementing ISO 50001 have a traceable and verifiable audit trail of how each energy performance improvement opportunity comes to be. This is particularly useful when preparing an ISO 50001 energy review.
ISO 50003 addresses the additional requirements placed on certification bodies providing ISO 50001 certification services. Designed based on ISO 17021 – the primary standard for certification bodies carrying out management systems audit such as ISO 9001 and ISO 14001, this standard describes the competences of lead energy management systems auditors, minimum information to audit, the duration of audits and requirements for multi-site sampling.
Apart from the formulas to calculate what constitute “representative sampling” and “sample size” in multi-site organisations, this standard is not intended to be read and used by organisations implementing ISO 50001.
ISO 50004, like ISO 9004 and ISO 14004, gives organisations examples on how to implement, maintain and improve their ISO 50001-based energy management system. The examples give ideas and additional suggestions that an organisation may want to use when meeting the requirements of ISO 50001.
Also, like other ISO XXX4 guidance, no organisations can be certified to ISO 50004. The examples and practical boxes are merely for illustrative purposes only. In addition, following all the examples in ISO 50004 does not guarantee an organisation to be successfully certified in ISO 50001. The key to be successful is using ISO 50004 is to select, adapt, and improve on the examples presented such that they become appropriate and relevant to the organisation.
Energy savings have primarily been driven by innovating and applying energy efficient products. ISO 50001 introduced a new and timely concept called “energy performance”. This is an important concept because it is similar to KPIs familiar to many business managers. It is also important as it defines, for the first time, that energy savings can be achieved by many means: energy use, energy consumption, and energy efficiency.
ISO 50006, also using examples, gives examples, ideas and approaches where an organisation can define, measure, monitor, and review its energy baseline and energy performance. When the baseline and energy performance indicators are appropriate, repeatable and statistically significant, it can be used to forecast future energy consumption, monitor energy performance and apply appropriate corrective and preventive actions – a key requirement of ISO 50001.
ISO 50015 describes standardised steps to quantify and verify the effectiveness of energy performance improvement projects against their planned outcome. It does not prescribe or recommend which approaches or calculation methods when verifying energy savings.
Although strictly not a requirement of ISO 50001, the ability to measure and verify energy savings ensures it is based on data, increases the traceability and verifiability of energy savings claims, adds quantifiable value of implementing ISO 50001 and maintains and enhances continued commitment in saving energy by top management.
Check back here next week for Part 3 where we provide an in depth overview of ISO 50002.
