Aiming at greater energy savings, the EU adopted Directive 2012/27/EU, which was incorporated into Greek legislation by Law No. 4342/2015 and provides for mandatory energy audits in companies that are not small and medium-sized enterprises (SMEs). The requirements are complemented by the Decree no. 175275 published on 30/5/2018, the international standards of the ISO 50001 series and the European standards of the EN 16247 series.

Based on the provisions of the Directive, energy audits must be based on up-to-date, measurable, traceable operational data in terms of energy consumption. In addition, they shall include a detailed overview of the energy consumption characteristics of a building or group of buildings, industrial activity or installation, including transport, be based, where possible, on life cycle cost analysis (LCCA) and be proportionate and sufficiently representative.

Energy audits are classified into 3 categories depending on the installation according to Law 4342/2015 (Article 10). TÜV HELLAS (TÜV NORD) has energy auditors on its staff who have been assessed by the Ministry of the Environment as class C auditors, the highest possible class, in order to cover all obligated companies. At the same time, they have extensive experience in energy management systems inspections, energy audits, energy audits and inspections in energy and renewable energy projects, ensuring that energy audits are carried out with the required expertise, experience, objectivity and reliability.

The energy audits are carried out in buildings, production and transport, and cover at least 90% of the total consumption, while during the energy audit by our organisation:

• Data is collected by the company, and in cases where there is insufficient data available, appropriate metering equipment is used for sampling at selected points of the facility and recording over time, in order to determine individual consumption.
• Based on the data collected, the energy baseline shall be established and the main energy uses and energy indicators shall be identified.
• The current state of energy performance shall be assessed.
• Energy saving measures shall be identified and evaluated using life cycle cost analysis (LCCA) rather than simple payback periods (SPP), in order to take into account long-term savings, residual values of long-term investments and revaluation rates.
• An energy audit assessment report shall be drawn up and sent to the competent authorities.

Given the continuous increase in energy prices, TÜV HELLAS' accredited energy auditors are at the side of the Greek company in order to identify its real needs and propose the most efficient energy saving measures. At the same time, TÜV HELLAS is an accredited certification body for Energy Management Systems according to the ISO 50001 standard.
