ISO 50006 PDF

Organizations across the world are gaining control of their energy spending by measuring and managing their utilities. In doing so, they may be using standards . BS ISO BSI Standards Publication Energy management systems — Measuring energy performance using energy baselines (EnB).

The energy baseline is also used for calculation of energy savings, as a reference before and after implementation of energy performance improvement actions.

BSI is incorporated by Royal Charter. After a period of time, the average specific power, calculated weekly, increased to a higher level than the average of previous weeks, and remained there for a month. The establishment of appropriate EnPIs and corresponding EnBs requires access to available organizational energy data, analysis of the data, and processing of energy information.

When a single relevant variable does not appear to significantly relate to energy consumption, the organization ido use a model-based EnPI, with two or more relevant variables see 4. Buying standards You can buy and download PDF versions of BSI publications, including British and adopted European and international standards, through our website at bsigroup.

In this case, the organization will need to assess, and consequently refine the EnPIs or introduce additional meters or is methods. We need your help! Need more than one copy? The organization should take measurements for each energy value and relevant variable necessary to calculate the selected EnPIs and the corresponding EnBs. If the statistical model is developed properly, then the values of the EnPI during the baseline period, or EnB, will predict the actual consumption during the baseline period accurately.


Over the past three years, a technical committee of the Canadian Standards Association CSA composed of industry experts and industrial users has been developing a standard for compressed air system energy performance measurement that fits the ISO and framework.

The difference between target and the current EnPI is also displayed.

ISO 50006 Energy Baseline (EnB) and Energy Performance Indicator (EnPI)

isi EnPIs are used to quantify the energy performance of the whole organization or its various parts. If continuous measurement is not possible, the organization should ensure that spot or temporary measurements are made during periods that are representative of the typical pattern of operation.

The following steps should be taken to establish an EnB: After visibly assessing trends in energy consumption and variables, the organization can assess the significance of the relationship. Organizations define targets for energy performance as part of the energy planning process in their EnMS.

The guidance in ISO Practical Help Box 1: The system has a sophisticated compressor control system that orchestrates the operation 500066 the system compressors to ensure all except one are fully loaded. Setting up an energy management system is more isl just installing instrumentation. Learn more about the cookies we use and how to change your settings.


Where operating patterns and the values of relevant variables fluctuate significantly, it is important to ensure that the data being analysed for correlations are at the correct frequency to enable the effects of each variable to be accurately observed.

If an organization is actively implementing its action plans, then this difference should be evident. Measurement and assessment of dynamic iwo, such as compressed air, can be tricky because constantly changing conditions, such as production volumes due to seasonal variations, or regular changes in product mix can change the energy consumption of a compressed air system.

Failures in the baseline and determining EnPI will resulted mislead performance that could lead to wrong decision by top management. Some systems are small with lower return on investment for energy measurement systems, therefore, methods to determine EnPIs should be simple. This could be illustrated in the following equation. Calculating energy performance improvements It can be difficult for organizations to choose from the large number of approaches to measure energy performance improvement.

Energy performance can be affected by a number of relevant variables and static factors. For example, where isp consumption per unit of production is being measured, counting the number of final products may provide a misleading result if there are intermediate outputs produced, and whether these intermediate outputs are waste, value added, or recycled. The source of energy should be specified together with relevant variables.
