Industrial energy audits

The industrial energy audit is a diagnostic and decision-making tool that enables you to reduce your energy consumption by identifying potential savings in your utilities(electricity metering, thermal energy metering, gas metering, water metering, steam metering, compressed air metering), industrial processes and buildings.

Objectives of an energy audit in industry :

1. Increase your energy efficiency
2. Reduce your production costs
3. Reduce your energy bill
4. Stop your energy losses
5. Optimizing your assets
6. Improving quality

Become an active player in your company's sustainable development, whatever your sector: carry out an industrial energy audit.

The energy audit is the cornerstone of your company's energy optimization strategy:

Energy audit methodology and standards systems

Define appropriate ratios and yields for quantitative or qualitative monitoring to improve and monitor energy efficiency.

European Directive 2012/27/EU

The Energy Efficiency Directive establishes a legal framework to support the European Union's drive to reduce greenhouse gas emissions. Article 8 of the directive obliges EU member states to introduce an energy audit for companies whose main activity is subject to regulatory obligations in terms of energy efficiency.

Energy performance monitoring: The ISO 50001 standard

Designed to help organizations in all sectors of activity, this standard proposes practical ways of reducing energy use through the implementation of an energy management system. A continuous improvement system is based on several stages:

1. Take stock of energy consumption
2. Identify the main areas of use
3. Define a policy for efficient energy use
4. Set targets and objectives to implement this policy
5. Use data to better understand problems and make decisions to remedy them
6. Measuring results
7. Reviewing policy effectiveness
8. Continuous improvement in energy management

NF EN16247-1 and NF EN16247-3 energy audit standards

Published in 2012, they present datasheet for energy audits of buildings and industrial facilities. They form the methodological basis for carrying out an energy audit according to the procedure described in the NF EN ISO 50001 standard. ADEME has drawn up a methodological guide based on these standards.

Drawing up a measurement plan: Standard NF EN 17267

The 6 steps for drawing up a metering plan, in compliance with the standard, constitute a guideline for ensuring that energy consumption is monitored and that effective efforts are made to reduce energy consumption in industry.

1. Define the context, objectives and constraints
2. Assessing the initial situation
3. Define an action plan to improve the measurement system
4. Set up the measurement system with the support of an industrial automation integrator
5. Maintain the measurement system
6. Exploiting measurements

One expertise, one team, one project: your energy audit

Communication solutions for your energy measurement sensors

Energy values, thermal and electrical energy metering and all your measurements are accessible locally for daily monitoring by your operators.

Thanks to our wired or wireless communication products, this data is transmitted from the meters to our touch interface via a Modbus-type fieldbus or via the HART protocol of our measuring instruments(pressure measurement, flow measurement, level measurement, temperature control, gas analysis and radiation protection).

A human-machine interface (HMI) enables measurements to be displayed in real time, either locally on site or remotely, and data to be saved. Communication protocols (Modbus, Ethernet, Profibus, etc.) available on the touch screen allow interfacing with existing automation systems, your supervision systems or our monitoring and energy optimization software.

The Monitouch man-machine interface software calculates the Energy Performance Indicators of your installations and shares them in a database.
