In accordance with the 2012 European directive on energy efficiency (2012/27/EU), companies with more than 250 employees are obliged to carry out an energy audit of their activities by December 5, 2015. Many manufacturers in France are concerned, and have not yet decided between the mandatory audit or ISO 50001 certification. Siemens is offering them a decision-support service to assess their operational systems and energy management procedures:
- an online self-assessment tool, the first phase of awareness-raising, accompanied by a presentation of Siemens energy efficiency solutions;
- a pre-diagnosis Energy Management Health Check, which enables the company to assess the organization of its energy management and the various avenues for improvement;
- various monitoring and analysis phases via Energy Analytics to help companies identify their savings potential with the aim of optimizing the energy efficiency of their facilities, with services tailored to their needs.
ISO 50001 or energy auditing of facilities
If a company falling within the scope of the directive fails to carry out this audit, it may be fined the equivalent of 2 % of its annual sales (financial year N-1). The audit must cover at least 80 % of the amount of energy invoices paid by the company. However, for all audits carried out before December 5, 2015, this coverage rate can be reduced to 65 %. ISO 50001 provides organizations with a normative framework for integrating energy performance into their management practices. Among other things, it aims to help operating units make more judicious use of their energy sources, promote best practices in energy management and use, reinforce good behavior in these areas, and evaluate and prioritize the application of new energy-efficient technologies. Any industrial company that does not integrate the energy efficiency process within its facilities, and therefore does not meet the ISO 50001 standard, will have to renew an energy audit every 4 years.
Siemens helps manufacturers to reduce their energy consumption
" Siemens is currently making manufacturers aware of the need to take stock of their energy consumption. To do so, they can already carry out a pre-diagnosis of their installation.n", explains Pierre Marzin, Service Sales Specialist in the Digital Factory division. The Siemens Energy Efficiency Service Center (CS2E) offers them a first level of online self-assessment. " Depending on the results, the operator is free to contact Siemens for further information and to ask the right questions about implementing an Energy Efficiency approach in line with the ISO 50001 standard. "continues Pierre Marzin.
L'Energy Management Health Check (EMHC) by Siemens examines energy management processes and evaluates current systems and procedures in every area of the company on a scale of 1 to 5 stars. This approach is structured in such a way as to determine the status of all energy fluids used, management processes and organizational structures. During the EMHC analysis, certain areas with optimization potential, or actions to be taken, will be identified and commented on in the final report. The next step will be to propose the implementation of a metering plan within the facilities. Indeed, to analyze the data inherent in the site, it is necessary to deploy the technical means to gather information and establish an initial overview: who consumes energy, where and how much?
Implementing an energy management system
Siemens offers several levels of monitoring and analysis to simplify the management of industrial energy consumption and ensure compliance with the ISO 50001 standard. On the basis of B-Data software, Siemens has developed various examination phases to help operators identify potential savings and optimize the energy efficiency of their facilities. An on-site "Energy Box" enables all the necessary information to be acquired and securely uploaded to a database. A platform Energy Analytics The dedicated system enables operators to log in at any time, using a login and password, to obtain the reports or analyses they require: potential gains at site, operational and field levels, a monthly management report, load profile comparison modules, energy cost allocation or even a non-productive analysis, for optimizing energy costs or purchases. Pierre Marzin emphasizes: " Simple energy transparency can reduce bills by 5 to 10 %, and identifying potential savings can reduce consumption within the system by up to 30 %. "
