Energy Audits

Aiming at greater energy savings, the EU enacted Directive 2012/27/EU which was incorporated into Greek legislation with Law 4342/2015 and provides for the mandatory performance of energy audits in businesses that are not small and medium-sized enterprises (SMEs). The requirements are completed by the decision. 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, include a detailed overview of the energy consumption characteristics of a building or group of buildings, an industrial activity or facility, including transport, be based where possible on a life cycle cost analysis (LCCA) and be proportionate and sufficiently representative.

The 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 in its staff who have been evaluated by the Ministry of the Interior as class C auditors, the highest possible class, in order to cover all liable businesses. At the same time, they have extensive experience in energy management system inspections, energy inspections, energy audits and inspections in energy projects and RES projects, ensuring that energy audits are carried out with the required know-how, experience, objectivity and reliability.

Energy audits are carried out in buildings, processes and transport, and concern at least 90% of total consumption, while during the energy audit by our organization:

• The energy data are collected from the company, while in cases where there are insufficient data available, suitable measuring equipment is used for sample measurement at selected points of the installation and recording over time, in order to determine the individual consumptions.
• Based on the data collected, the energy baseline is established and the main energy uses and energy indicators are determined.
• The current energy performance is assessed.
• Energy saving measures are identified and evaluated using the Life Cycle Cost Analysis (LCCA) method rather than simple payback periods (SPP), in order to take into account long-term savings, residual values of long-term investments and revaluation rates.
• The energy audit evaluation report is drawn up and sent to the competent authorities.

Given the continuous increase in energy prices, the qualified energy auditors of TÜV HELLAS are next to 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 (EnMS) according to ISO 50001.
