Energy Audit and Energy Diagnosis

auditoria-energetica

 

An energy audit comprises the inspection, study and analysis of the flows of energy in a building, industry, process or system, and is designed to demonstrate the dynamic energy of the system being studied. Its fundamental aim is the reduction of consumption and, therefore, energy and financial savings.

 

To fulfil this objective, an energy audit is based on three fundamental premises:

  • To adjust a plant’s real consumption to the nominal levels, guaranteeing good maintenance of the installations.
  • To reduce nominal consumption with new technologies that raise energy consumption efficiency.
  • To minimise the energy demands of the process, optimising energy services operation.

There are a number of stages to the energy audit process:

  • A study of the system being analysed, with an audit of the following:
    • consumption habits
    • heating and air conditioning equipment
    • electrical equipment
    • lighting equipment
    • the thermal insulation of the installation
  • An analysis of the data gathered.
  • Confirmation of data and values.
  • Proposal for improvements.

An energy audit may be broader or narrower in scope depending on its depth, and ranges from basic energy diagnosis to the implantation of measures funded through an energy services company (the ESE audit).
