The purpose of an energy audit, and the use that can be given to the document, make this kind of contribution very valuable service to the customer. The objectives are,

  • Knowing the energy consumption (gas, electricity, steam, etc.)
  • Identify the largest consumption, and its processes,
  • Where and how to save energy and thus reduce costs and expenses,

These general steps follow a logical line when it comes to identify the profile of consumption, type of energy consumed and how both its transformation as the way it is done, inventory of energy consuming equipment. Once these aspects are known, the factors influencing consumption are identified, and technologies, we can identify savings opportunities, gathering all in a report.

Steps to an Energy Audit



Making contact and preliminary data processing and preliminary evaluation.


Energy audit in situ or making detailed remote data, and analysis of the situation.

Evaluating savings opportunities

Saving options and starting point for energy objectives. Energy efficiency, environmental assessment, economic and financial analysis.

Audit Report

Report preparation and presentation to the company.



The consumption profile refers to measured operational and verifiable, load profiles and consumption cycles, and even data if required pursuant to Directive 2012/27/EU Energy Efficiency also can assess the economic lifecycle investments.

Prior to the measurement of consumption data, an audit plan is prepared, with historical data and variables affecting consumption (outside temperature, occupancy, operating hours, etc.) for the purpose of the audit is able to identify correctly and verification. Therefore, there are protocols by type of energy and its uses.

Energy audits have become mandatory for large companies, which must be performed before 05/12/2015 and return to perform at intervals of four years from the previous audit. Guidelines to audit clients can fix them, but our proposal is based on ISO 50001 since the method is endorsed by the Directive in Annex IV.
