Broadly speaking,
auditing energy is possible through one of the following four methods:
-
Fast auditing (transitional): This kind of auditing includes a fast and superficial
visit of the possibilities and equipments during which those points and equipments
are mentioned and suggested which could save on energy through slight or cheap modifications.
Such suggestions could include pipe insulation of warm water network, an elementary
examination of compacted air system, and a proposal for impeding the sink decrease
in compacted air systems and so on.
-
An analysis of equipment functioning: The main aim of this kind of energy
auditing is to determine the costs of different operational equipments. The operational
information of the equipments during the last years are gathered and analyzed, so
that patterns of energy consumption, the highest amount of demand and the potentials
of saving in energy consumption are recognized.
-
Standard energy audit: Along side with the two mentioned methods of energy
audit, this kind of energy audit includes an estimation of consumed energy in equipments
and an approximate estimation of saving amount in energy use of the equipments because
of optimizing measures.
-
Comprehensive
energy audit: This kind of energy audit has an appropriate exactitude, although
time consuming and expensive. This kind of energy audit may be possible by using
advanced measuring equipments and computer simulations. They could pave the way
for an exact determination of energy use in each of the equipment and then the saving
amount in each one of them after having implemented the mentioned modifications.
The needed data are measured, registered and gathered directly and then they are
analyzed. The most important features of this kind of energy audit are its comprehensive
view and a total use of engineering analyses and different simulations of equipments
and processes.
