Energy Audit:
Energy audit is an inspection, survey and analysis of energy flow for energy conservation in a
building, process or system. It is done with a view to reduce the amount of energy input into
the system without negatively affecting the output(s).
An Energy Audit is a survey conducted by an Energy Auditor to determine how much energy
a building uses and identify ways to reduce energy consumption. These are used to improve
the energy efficiency of homes, businesses, and other buildings.
As per the Energy Conservation Act, 2001, an energy audit is defined as “the verification,
monitoring and analysis of use of energy including submission of a technical report
containing recommendations for improving energy efficiency with cost benefit analysis and
an action plan to reduce energy consumption.”
Need for energy audit
The functions of the energy audit are,
- an energy audit can reduce energy consumption
- an energy audit can reduce the energy bill and save the money
- an energy audit can improve the comfort level
- an energy audit can reduce the carbon footprints
- an energy audit can reduce unnecessary waste and pollution
The energy audit is the great and most valuable step to save energy consumption and save
money.
Types of Energy Audit
There are several types of energy audits: walk-through energy audits, target energy audits, and
detailed energy audits.
Walk-through Energy Audits
The simplest and fastest type of energy audit is a walk-through energy audit. It is defined as
the simple surveying audit in which the auditor only investigates the energy consumption of an
organization and in this type of energy audit no major steps will be taken for consuming energy,
it is also known as a preliminary audit. It is the first step of auditing and it is the simplest and
quickest type of audit. And is focused on the major energy consumption area. The walk-through
energy audit is completed in the lesser time of spam. The auditor will find the energy
consumption area and developed the full list of the energy-saving measures.
Target Energy Audits
A target energy audit is more comprehensive than a walk-through energy audit. The target
energy audit starts with the finding of the walk-through energy audit. This type of audit
provides a detailed analysis of a specific project. This energy audit approach differs depending
upon the structure type whether it is a commercial structure, residential, or industrial structure,
but in all the structures more detailed information and data are needed. The outcomes are the
recommendations regarding the actions to be taken. A clear and brief energy report should be
submitted including the action plan “how to improve energy efficiency”.
