Whenever we face an analysis of the real use of the “building – technological systems” system, we can resort to an energy audit. This can be described as an investigation, detection and analysis of energy flows in a building, system or procedure, aimed at reducing the amount of energy fed into the system, without negatively affecting performance.
The Energy Audit is a way to identify Energy Conservation Opportunities (ECO) or measures (ECM). The energy saving opportunities or measures consist in a more efficient use of existing plants or in a partial/global replacement of the systems themselves.
An energy audit consists of the following steps:
