ISO 50006-2014 pdf free download.Energy management systems – Measuring energy performance using energy baselines EnB) and energy performance indicators (EnPI) – General principles and guidance.
ISO 50006 provides guidance to organizations on how to establish, use and maintain energy performance indicators (EnPis) and energy baselines (EnBs) as part of the process of measuring energy performance.
The guidance in this International Standard is applicable to any organization, regardless of its size, type, location or level of maturity in the field of energy management.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 50001 and the following apply.
3.1 adjustment
process of modifying the energy baseline in order to enable energy performance comparison under equivalent conditions between the reporting period and the baseline period
Note 1 to entry: ISO 50001 requires adjustments to the EnB when EnPIs no longer reflect organizational energy use and consumption, or when there have been major changes to the process. operational patterns, or energy systems, or according to a predetermined method.
Note 2 to entry: Typically adjustments are made to account for changes in static factors. Note 3 to entry: Predetermined methods typically reset the EnK at defined intervals.
3.2 baseline period defined period of time used to compare energy performance with the reporting period
3.3 boundaries physical or site limits and/or organizational limits as defined by the organization
4.1 General overview
4.1.1 General
In order to effectively measure and quantify its energy performance, an organization establishes EnPis and EnBs. EnPis are used to quantify the energy performance of the whole organization or its various parts. EnBs are quantitative references used to compare EnPI values over time and to quantify changes in energy performance.
Energy performance results can be expressed in units of consumption (e.g. Gj, kwh). specific energy consumption (SEC) (e.g. kwh/unit), peak power (e.g. kW), percent change in efficiency or dimensionless ratios, etc. The general relationship between energy performance, EnPis, EnBs and energy targets is illustrated in Figure 1 in the introduction.
Energy performance can be affected by a number of relevant variables and static factors. These can be linked to changing business conditions such as market demand, sales and profitability.
An overview of the process to develop, use and update EnPIs and EnBs is illustrated in Figure 2 and described in detail in 42 to 4.f. This process helps the organization to continually improve the measurement of its energy performance.
4.1.2 Energy consumption
Quantifying energy consumption is essential for measu ring energy performance and energy performance improvements.
When multiple forms of energy are used, it is useful to convert all forms to a common unit of measure of energy. Care should be taken to perform the conversion in a manner that appropriately represents total energy consumed including losses in the energy conversion process.
4.1.3 Energy use
Identifying energy uses such as energy systems (e.g. compressed air, steam, chilled water, etc.), processes and equipment helps to categorize energy consumption and to focus energy performance on uses that are important to an organization.
4.1.4 Energy efficiency
Energy efficiency is a frequently used metric for measuring energy performance and may be used as an EnPI.ISO 50006 pdf download.
