Management Review: decisions and actions to improve the energy performance
●
Regular, detailed energy audits (not just once like in the environmental review)
●
Checklists
Integration of ISO 50001 into ISO 14001 (1) Energy Policy:
●
●
●
includes the term Energy Efficiency Energy objectives have to be measurable, documented, and labeled with a timeframe includes a commitment to ensure the availability of information and of all necessary resources to achieve objectives and targets
Integration of ISO 50001 into ISO 14001 (2) Planning
To add to ISO 14001: ●

●
Energy indicators
●
Prominent areas of energy consumptions: summary of changes in retrospective and estimation of future energy consumptions
Integration of ISO 50001 into ISO 14001 (3) Implementation and Operation
To add to ISO 14001: ●
Qualification and competence of management representative concerning energy efficiency
●
Additional topic for training: energy
●
Energetic consideration in procurement, energy efficiency as a criterion
●
Rate the energy consumption in the interpretation, modification or repair of any assets, including buildings, with substantial impact on energy consumption
Integration of ISO 50001 into ISO 14001 (4) Monitor and Measure
To add to ISO 14001: ●
●
●
●
Set the relationship between energy consumption and associated factors for every practicable case and assess the actual energy consumption compared to the expected at fixed time intervals. Hold records of all significant unplanned deviations from the expected energy consumption, including the reasons and remedies. The relationships between energy consumption and energy factors must be reviewed at set intervals and revised as necessary. Whenever possible, the organization has to compare the indicators for their energetic performance with similar internal or external organizations or constellations.

Energy Monitoring Technical Requirements
www.efficiency-from-germany.info
Energy Management System ISO 50001 – Monitor and Measure
●
Energy-review has to contain: ●
●
Historical and actual energy consumption on the basis of measurements and other data
Goals of energy reduction = relative measurement of energy use ●
Energy use per piece, per kg, per m² or something comparable
●
Goal of energy independent of change in production
Energy Management System ISO 50001 – Monitor and Measure
● ●
Define operative goals Analysis of energy consumptions (e. g. of processes, compressed-air, heating, illumination,...) is facilitated
●
Intermittent estimation and validation of energy consumptions
●
Introduction of performance indicators for energetic power ●
e. g. kWh per production unit
●
e. g. kWh per m² building area
●
Use key values for ongoing control, to assure intervention in the case of deviations
Energy Management System ISO 50001 – Monitor and Measure Examples for Monitor and Measure: ●
Ongoing monitoring and recording
●
Summary in the form of key values
●
Analysis of key values for validation
●
Intervention in case of deviations
●
Examination of power and adaptation of goals
Energy Management System ISO 50001 – Monitor and Measure
●
Calibration of measurement set-up and storage of data recordings
●
Requirement: identification of improvements
●
●
Measurements as well as measurement techniques have to be comprehensible at every status The reproducibility is leading, not the accuracy of the measurements
Energy Management System ISO 50001 Monitor and Measure – Introduction of Procedures Procedures should describe the following: ●
How are energy consumptions measured, recorded and monitored
●
The comprehension of monitoring, including the measuring intervals
●
Calibration and maintenance of the measurement set-up
●
Tasks and responsibilities of the relevant personnel
●
How energy consumption is presented against the performance indicators for energetic power

Current Transformer
●
The advantage of the split core type (left), is an easy integration into running systems. Normally no switching-off is necessary
●
Must of course right dimensioned for the existing power rails or cables
●
In switched-on systems installing by an electrician only!
Note: The operation of a Current Transformer in idle state generates a large magnetic flux in the input winding and can destroy the CT. Therefore, the CT must always be shortcircuited during installing / de-installing

S0-Pulse Interface Functional Scheme
Meter Data Logger (e.g. VIDA350)
The pulse generator of a meter is connected with 24V DC (for example by a digital input from the Vida350). If the optocoupler gets a pulse of the counter, the circuit is closed and the Vida adds one pulse. According to the standards, the voltage can be around 20-30 V and the current can be around 20-30 mA (approximate values) Meters that have not a S0 standard pulse output can be destroyed by too much voltage or current! Therefore these meters need a S0 converter
S0-Converter
Meter Data Logger (e.g. VIDA350)
●
Connection up to 3 water or gas meters
●
3 galvanically insulated digital inputs
●
With a voltage of < 5V and a current of < 6mA suitable for connection of sensitive pulse generators
→ for details see manual of VIDA350

The neutral wire N to terminal 11 The two connections of the secondary circuit of the three current transformers (K and L) are connected to the terminals 1, 3 / 4, 6 / 7, 9 The 24V DC for the S0 pulse generator are connected to the terminals 20 and 21 - or - if an inverted one is necessary at 22 and 21 The terminals 23 and 24 are for a bus connection, like LON, M-Bus, etc.
U1389 Meter – Display U
Main display is not/cannot be calibrated, if U is displayed. Correct connection: Continuously lit phase symbols Phase failure: Symbol for affected phase is cleared from display. Incorrect phase sequence: Phase symbols blink in the following order: 3-2-1. Negative power: Respective phase symbol blinks. 4 quadrant display of instantaneous power: positive or negative active power P, positive or negative reactive power Q. For bus connection: appears when the meter transmits a data packet.

Energy Management System ISO 50001 Metering Point Concept (What to Measure, How and Where) Points for consideration in a Metering Point Concept: ●
●
●
●
●
●
●
which are the most interesting measuring points, regarding minimal wiring and installation costs check the existing counters for compatibility, are maybe new meters or pulse converters necessary what is the best equipment (Standard or maybe LonWorks Components, if additional are interesting) definition of data transfer and interfaces for existing systems where is the best locations for the installation of data loggers (consideration economically aspects, cabling effort, GSM reception, etc.) what are the best measurement intervals (for example 15 minutes)
If these points are clarified, a Metering Point Concept table should be created. This is a good overview and makes the integration of the measuring points in JEVis easier.
