The consumptions and utilisation of energy in your company is an important aspect to focus on. we along with our professionals help you in growing efficiently. Energy Audit is a vital link in the entire management chain. The energy manager, while proposing various courses of action and evaluating their consequences, requires a detailed information base to work from energy audit attempts to balance the total energy inputs with its use and serves to identify all the energy streams in the system and quantifies energy usages according to its discrete function. An energy audit is an effective tool for defining and pursuing comprehensive energy management programmes. It has a positive approach aiming at continuous improvement in energy utilization in contrast to financial audit which stresses to maintain regularity. An energy audit provides an answer to the question – what to do, where to start, at what cost and for what benefits?

Energy audit helps in energy cost optimization, pollution control, safety aspects and suggests methods to improve the operating and maintenance practices of the system. 

Objectives of Energy Audit:

The energy audit provides the vital information base for overall energy conservation programme covering essentially energy utilization analysis and evaluation of energy conservation measures.

It aims at:

  1. Assessing present pattern of energy consumption in different cost centres of operations

  2. Relating energy inputs and production output

  3. Identifying potential areas of thermal and electrical energy economy.

  4. Highlighting wastage in major areas

  5. Fixing of energy saving potential targets for individual cost centres

  6. Implementation of measures of energy conservation and realisation of savings.


The overall objectives of the Energy Audit are accomplished by:

  1. Identifying areas of improvement and formulation of energy conservation measures requiring no investment or marginal investment through system improvements and optimisation of operations.

  2. Identifying areas requiring major investment by incorporation of modern energy efficient equipment and up-gradation of existing equipment.

Types of energy audit:

The energy audit can be of the following two types:

  1. Preliminary audit

  2. Detailed audit

Preliminary audit

Preliminary audit is carried out in the limited time say within 10 days and it highlights the energy cost and wastages in the major equipment and processes. It also gives the major energy supplies and demanding accounting. The questionnaire containing the industrial details of energy consumption process carried out, energy needed to unit product; load data etc. must be completed before the pre-audit visit. The pre-audit visit is done, by the audit team/audit consultant, in the plant area with the attention focused on the energy inputs, spots of wastage and available energy conservation opportunities. The items for waste recycling opportunities are identified. The data regarding energy inputs and outputs are collected for use during preliminary audits.

Detailed audit

Detailed energy audit, also known as comprehensive energy audit, includes engineering recommendations and well-defined projects with priorities. It accounts for the total energy utilised in plants. It involves detailed engineering for options to reduce energy consumption and also reduce cost. The duration of such studies is generally from 1 to 10 weeks. The action plan is divided into short term, medium term and long-term actions.

The short-term action plan requires no capital investment or least investment to avoid energy wastages and minimising non-essential energy uses and improving the system efficiency through improved maintenance programme.

The medium-term action plan requires a little investment to achieve efficiency improvement through modifications of existing equipment and other operations.

The long-term action plan is aimed to achieve the economy through the latest energy saving techniques and innovations. The capital investments are required to be studied thoroughly while finalising the long-term action-plan.

Report of Energy Audit:

The comprehensive energy audit report generally converts the following:

  1. Energy conservation opportunities (ECOs)

  2. Energy conservation measures (ECMs)

  3. Projected investments for ECMs.

  4. Projected annual savings of ECMs and pay-back period.

  5. Feasibility studies for retrofitting/modification work.

Benefits of energy audit:

  • It helps reduce energy costs in your facility.

  • With a reduction in production costs, the competitiveness of your company will be improved.

  • It helps reduce the dependence on foreign energy sources.

  • It helps reduce environmental damage and pollution.

  • It can increase the security of your energy supply.

  • It can reduce the consumption of natural resources.

  • It can reduce damage to the environment associated with the exploitation of resources.

  • It helps reduce the impact of greenhouse gas emissions.


Q 1. Why should I have an energy audit?

Ans. Much like the human body, our homes are made up of complex systems that work together.  If there is a problem with one of the systems, we get symptoms like uncomfortable rooms or high utility bills.  An energy audit allows you to set priorities for improving your home so you get the most improvement for your money based on building science, not flashy sales pitches.

Q 2. What does an energy audit include?

Ans. All audits performed by Efficient Energy Solutions start with a thorough visual inspection of the entire home and all the systems in it.  This is thoroughly documented with photos.  Depending on the type of audit, the visual inspection is followed by a blower door test, a duct blaster test, and combustion safety testing.  Once these tests are complete our energy auditors will sit with homeowners to give a visual presentation of all the photos taken during the energy audit.  Afterward, the homeowner is provided with a Prioritized Improvement Plan and a Recommendations Report.

Q 3. What is a duct blaster test?

Ans. A duct blaster tests the leakiness of the duct systems in the home.  The average duct system leaks 25%.  This means that ¼ of the air flowing through the ducts either leaks outside (wasting money) or brings outside air into the duct system (bring outside contaminants in).

Q 4. Why do you take so many photos?

Ans. This allows the homeowner to see exactly what the energy auditor sees at the time of the audit.  This helps the homeowner understand the effects of the conditions noted by the auditor.

Q 5.  How long does an energy audit take?

Ans. There are several factors that determine how long an energy audit takes.  The size of the house, the number of HVAC units, and how easily areas in the attic, basement, and crawl spaces are all major factors.  A full diagnostic energy audit takes from 4 to 6 hours.  A Visual Energy Assessment takes around 2 hours.
