energy diagnosis

The energy diagnosis aims to provide an energy framework of the company’s site through the construction of energy models, with details of the main users and distribution of their consumption.

The use of summaries of detailed models for cost centers, areas or utilities allow:

  • an immediate comparison of the site with industry benchmarks, allowing You to identify the critical points
  • the related proposal for energy saving measures, with quantification of the economic benefits and the maximum investment.

The energy diagnosis is carried out thanks to the high experience and professionalism of ALENS’s technicians, without the need to use measuring instruments, allowing reduced time and costs (except in specific cases, where it is necessary to proceed with detailed measures in the field).

Energy diagnosis is carried out in compliance with the UNI CEI EN 16247 regulation.
Enea has provided information about the modalities to conduce the monitoring plan, which has to support  the diagnosis, predicting it continuously for the whole solar year preceding the diagnosis (or in sample surveys in particular cases).  

In addition, Enea has provided guidance on how to carry out the monitoring plan which supports the diagnosis throughout the calendar year preceding the diagnosis (by sampling in particular cases).
