Energy Audits

Tool to assess the energy footprint of companies and energy efficiency strategies

TerrAria carries out energy audits for obligated entities pursuant to Legislative Decree 102/2014, as well as for voluntary entities. Large enterprises and energy-intensive companies are required to perform an energy audit every 4 years, starting from the first deadline set on 5 December 2015, in compliance with Legislative Decree 102/2014, which transposes Directive 2012/27/EU on energy efficiency.

The energy audit is an important tool for companies to understand their energy footprint and to assess energy efficiency measures. It is the instrument through which the consumption profile, energy balance and energy management of a company are analysed, with the aim of identifying and quantifying energy efficiency opportunities in the production processes involved, in the general and auxiliary services supporting them, and finally in the building-plant system in which the company operates.

The main steps of the audit are:

• acquisition and processing of consumption data: energy consumption monitored through electricity meters and the gas meter;
• calculation of energy performance indicators based on production data at the highest available level of detail;
• on-site inspection of the production facility, with verification of data and characteristics (power, efficiency, operating hours, etc.) of the main machinery;
• analysis of the collected information and identification of any need for further investigation;
• discussion with the company on the pre-feasibility of possible energy efficiency measures;
• preparation of the audit report, in compliance with the provisions of Legislative Decree 102/2014.

For the preparation of energy audits, TerrAria uses ERGapp, a Web application developed in-house and delivered via browser as a service accessible from any device (PC, tablet, smartphone), capable of monitoring and analysing energy consumption in real time, reconstructing historical consumption series, displaying power quality parameters, analysing EnPIs (energy performance indicators) and corporate KPIs (Key Performance Indicators), and simulating the savings achievable from each identified energy efficiency measure.
