Energy Audit

Energy Audit

1.      Energy Audit

It is an inspection survey and an analysis of energy flows for energy conservation in a building. It may include a process or system to reduce the amount of energy input into the system without negatively affecting the output. It is important as it identifies opportunities to reduce energy expense and carbon footprint by determining areas where there is energy loss and where energy can be curbed.

2.      Components of an energy audit

Ø  Evaluation or Air Leakage

One of the important parts of an energy audit is checking for trouble spots where air is leaking out of a home. A device called a blower door is used to measure air leakage.

Ø  Assessment of Insulation

If a home has inadequate insulation, it makes it much easier for heat to escape in the winter, and cool air-conditioned air to leave in the summer.  By measuring the thickness of insulation, an energy auditor can help determine if there is a sufficient amount, and make recommendation if needed. An energy audit can help homeowners determine if they have adequate insulation.

Ø  Examination of Water Usage

Water consumption is another thing an energy auditor can measure.  Using excessive amounts of water can also contribute to an increased utility bill.  High-efficiency shower heads, toilets and washing machines are all innovations that can assist in water conservation.  An energy audit can identify shower heads, toilets and washing machines that are wasting water. An audit is a good first step when developing a sound plan for conserving energy.

3.      Significance in carrying out an energy audit in a building

The Energy Audit provides the vital information base for overall energy conservation program covering essentially energy utilization analysis and evaluation of energy conservation measures. It aims at:

Ø  Identifying the quality and cost of various energy inputs.

Ø  Assessing present pattern of energy consumption in different cost centers of operations.

Ø  Relating energy inputs and production output.

Ø  Identifying potential areas of thermal and electrical energy economy.

Ø  Highlighting wastage’s in major areas.

Ø  Fixing of energy saving potential targets for individual cost centers.

Ø  Implementation of measures for energy conservation & realization of savings.
