Energy audits EN 16247/ISO 50002

An energy audit is key to developing an energy management program. Although energy

audits have various degrees of complexity and can vary widely from one organization to

another, every audit typically involves


  • data collection and review
  • plant surveys and system measurements
  • observation and review of operating practices
  • data analysis


In short, the audit is designed to determine where, when, why and how energy is

being used. This information can then be used to identify opportunities to improve

efficiency, decrease energy costs and reduce greenhouse gas emissions that contribute

to climate change. Energy audits can also verify the effectiveness of energy management

opportunities (EMOs) after they have been implemented.


We are certified energy auditors to comply with the requirements of Directive 2012/27 / EU on energy audits.

Energy Savings

The industry is one of the sectors of society which energy savings are needed. In the transport sector fuel savings is very important. Moreover, building design should consider, for example, insulation or building allocation in order to leverage solar energy for heating in winter.


Depending on the area you are analysing, the potential savings can reach 70% of the energy consumed. An example is lighting. Other technologies like ventilation can only reach a maximum of 25%. These are merely theoretical values, which have to be re validated after an in situ analysis.


Sometimes, the full potential cannot be exploited due to specific customer needs or simply because legal issues regarding air quality parameters.


In conclusion, only after an analysis of the actual situation in the company, potential real savings can be identified.


We check these savings according to the guidelines of different methodologies such as EVO protocols, ASHRAE guidelines or the new international standard ISO 50015.
