● Management Review: decisions and actions to improve the energy performance

● Regular, detailed energy audits (not just once like in the environmental review)

● Checklists

Differences ISO 14001 / ISO 50001

Energy Policy:

● includes the term Energy Efficiency

● Energy objectives have to be measurable, documented, and labeled with a time-frame

● 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 (1)

Planning

To add to ISO 14001:

● Energetic aspects

● Energy indicators

● Prominent areas of energy consumptions: summary of changes in retrospective and estimation of future energy consumptions


Implementation and Operation


● 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


Monitor and Measure


● 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.

Integration of ISO 50001 into ISO 14001 (5) – The Special Role of the Energy Team

● Commitment of the company to meet certain rules and specifications

● Rules and specifications can the defined by the company

● According to the energy policy and the strategic and operative action plans

● Compliance of all legal requirements

● Compliance must be confirmed through the compliance management

Compliance Management

4 keystones of the Compliance Management

Identification of risks

Internal control system

Internal and external communication system

Internal information system

ComplianceManagement


● Identification and analysis of legal risks● Knowledge about the legal framework

● Evaluation of needed trainings● Development and improvement of company policies

Identification of risks

Internal information system


Internal and external communication system

● Reporting system for violations ● Development of a method for complaints ● Contacts with authorities

● Call of a compliance manager ● Development of a control method for the communication

Internal control system


http://www.energymanager.eu/

● Several years of professional experience in related areas

● Not necessarily, but definite advantages are:

● Education that corresponds to the activity

● e.g. technical education or technical studies

● Certificate as energy manager from recognized certification bodies

● European training for energy managers (EUREM)

The Energy Manager: Training, Qualifications, Requirements

● Looks after the implementation of EnMS

● Checks and controls the results, counteracts for non-compliance

● Communicates all results with top management

● Interface between the top management and the remaining employees

● Controls the energy team

● Size of the energy team depends on the size of the company


Internal Marketing

Do good things and talk about it

● An energy manager must represent his actions in the company as well

● Periodical reports for the employees and the management

● Achieved savings must be communicated

● Set the achieved performance into a striking ratio



Energy Monitoring

Technical Requirements

● 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


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


● 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


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

● Vortex-, ultrasonic flow meter

Energy Management System ISO 50001 – Measuring Technique

● Fan-, volume meter, Woltmann meter● Ultrasonic flow meter

● Flow meter ● Thermometer

● Pressure-, partial pressure transmitter

Energy Management System ISO 50001 – Measuring Technique

● 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 short-circuited during installing / de-installing

Current Transformer

• Flexible metering coil to be placed around power line• Metering principle based on rogowski effect (induction)

Mode select voltage Um Mode

0V ≤ Um ≤ 12V Analog output in VAC

12V < Um ≤ 18V Digital pulse output

18V < Um ≤ 24V Debug mode

Medaflex Clamp-on Ammeter

● 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

Meter <-- --> Data Logger (e.g. VIDA350)

S0-Pulse Interface Functional Scheme

● 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

Meter <-- --> Data Logger (e.g. VIDA350)

S0-Converter

• Acquires active energy (import) with electronic reverse-action lock

• 2, 3 or 4-wire systems with any load• Long distance transmission of energy import pulses

via S0 interface with pulse rate according to selected features, LON, M bus or L bus interface

• For household, industrial and commercial applications

• Class 1, PTB approval• Direct (U128x) connection or via transformer

(U138x) – fixed or programmable transformation ratio

• LCD for:– Active energy and instantaneous power– Phase and phase sequence– Reversed current transformer polarity and

exceeded ranges– Positive or negative active or reactive power– Parameters enabling

• CT, VT and S0 parameters can be:fixed, calibrated, adjusted, enabled and disabled

• Test LED for calibration purposes

U1389 Electronic Active Energy Meter from GMC

● The three phases L1, L2, L3 are connected to the terminals 2, 5, 8. 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

The DS18B20 perform a measuring range from -55°C up to 124°C. For the operation above 100°C, an external voltage supply is recommend.Connections: 1: GND 2: DATA 3: VDD

1-Wire Temperature Sensor DS18B20

• VIDA350 supports up to 18 compatible (DS18B20) 1-Wire temperature sensors

• The 1-Wire bus provides different types of wiring (tree, star or chain structure)

• The 1-Wire devices are connected to the VIDA350 using screwing clamp 7 (Data) and 9 (GND)

• To offer a well structured bus communication every 1-Wire sensor has an explicit ID number

1-Wire Temperature Sensor

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.
