factory installation entirely. From the energy
balance, it can be determined the efficiency of
equipment and the presence or absence of
energy cost savings opportunities. After that, a more
detail test on each opportunity, estimated costs
and benefits of those choices that have been
determined is conducted.
In some cases, the energy auditor cannot
provide recommendations regarding a particular
investment, due to the risks or because the total
of investment is too large. In such cases, the energy
auditor will provide a recommendation regarding the
feasibility study (e.g. replacement of boilers,
furnaces, water vapor system and the process
changing).
The final DEA result will be a detail report
containing recommnedation along with benefits and
related costs and implementation program.
In general, it is quite difficult to deduce the
amount of savings that can be identified through the
energy audits. However, savings are usually close
to significant numbers, even through the simplest
energy audit. As a rough guide, the initial
energy audits are expected to identify savings
of 10 percent, which generally can be achieved
through house-keeping action at the factory
installation, or other actions that require little capital
investment. Detailed energy audits can
often achieved savings of 20 percent or more
for medium and long term period.
