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). (PER) et d’indicateurs de performance énergétique (IPÉ) — Principes généraux et lignes directrices. STANDARD. ISO. First edition.

If some outlying measurements are excluded, care should be taken that this does not introduce bias into the EnPI or 5006 EnB. Like any SEU, this management is done by measuring specific elements of the system within a specific measurement boundary. EnBs are quantitative references used to compare EnPI values over time and to quantify changes in energy performance.
For example, a factory with multiple activities might need to submit a single EnPI value to meet a government programme requirement. The organization should select an adequate data collection frequency for each energy consumption and relevant variable included in the EnPI and the corresponding EnB. Identifying and analysing outliers It can be challenging to identify and analyse outliers.
If the variable is relevant, one expects to see evidence of a relationship in the scatter of points. However, energy variables related to the measperformance improvement ures being included. Accept and continue Learn more about the cookies we use and how to change your settings.
Energy 5006 can be represented in volume and mass flow or weight units fuel or converted into units that are multiples of joules or watt-hours e.
Information on standards We can provide you with the knowledge that your organization needs to succeed. Compressed air systems can be managed by setting specific EnPIs that relate to the energy performance of the system. This standard is not included in any packages. A strategic decision of such a nature would necessitate the updating of the EnB to a recent period such as the last year to serve as the new reference point.
NOTE In some cases, such as when a new facility is being constructed and there is no appropriate operating history, it can be necessary to simulate, estimate or calculate the expected energy consumption for the new facility to serve as the EnB. Users are responsible for its correct application. The difference between target and the current EnPI is also displayed.
ISO 50006 Energy Baseline (EnB) and Energy Performance Indicator (EnPI)
After visibly assessing trends in energy consumption and variables, the organization can assess the significance of the relationship. Energy performance is a broad conceptwhich is related to energy consumption, energy use and energy efficiency.
Some organizations will develop a baseline using standard operating conditions, based on multiyear data.
The EnB enables an organization to assess changes in energy performance between selected periods. For example, if market demand required a change in the mix of products produced during andthe drop in consumption cited above might or might not be related to improvements in energy performance. When selecting appropriate EnPIs, key factors to consider are the users of the information and their needs.
This is called data collection frequency. We need your help! General principles and guidance.

The comparison might also show iao energy savings as result of an energy improvement project. This could be illustrated in the following equation. This is the change in values from the baseline period to the reporting period, expressed as a percentage of the EnB value. The organization needs to consider the specific energy performance targets while identifying and designing EnPIs and EnBs.
Engineering based theory can be applied where complex relationships exist between energy consumption and relevant variables that cannot be accurately captured with regression. An organization may discover that some of the EnPIs that were identified previously as significant may not be measurable due to data limitations or other barriers.
Short EnB durations may also be necessary for situations in which there is an insufficient quantity of reliable, appropriate or available historical data e. Data analysis in this isl, indicates that raw material quality does not cause a significant change in energy consumption. The measurement system tracks system specific power and energy consumption.
One year also lso the full range of seasons and hence can sio the impact of relevant variables such as weather on energy use and consumption. The organization should review these static factors over time, to ensure that the EnPIs and EnBs remain appropriate and to record any major changes that could affect 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.
Practical Help Box 7: Reviews There are no reviews 50006. An organization should set an energy target and an energy baseline for each EnPI. Data collection is performed periodically e.
As a minimum, it is recommended that organizations establish at least two EnB operational status conditions: The energy performances achieved by the enterprises as the result of ISO implementation should be appropriately determined based on a valid baseline and energy performance indicator.
Detailed results may be better suited for the engineers in order to find opportunities for establishing energy performance improvement actions. ISO Lead auditor and auditor especially from certification body as part of ISO requirement and compliance to accreditation scheme. Sustainability or energy team of group enterprises or corporate level in order to define appropriate baseline uso performance indicator 550006 their member of group and subsidiaries, which extremely important to determine the performance and benchmarking of energy performance within their group of enterprises.
Take the smart route to manage medical device compliance. BSI is incorporated by Royal Charter. For the purposes of this International Standard, energy refers to the various forms of energy, including renewable, which can be purchased, stored, treated, used 500006 equipment or in a process, or recovered.

The main types of EnPIs are: Certified energy manager who want to learn more on how to develop energy baseline EnB and energy performance indicator EnPI based on International recognized standard.
