What methodology is used in energy audit?

What methodology is used in energy audit?

3.2Energy Audit: Types And Methodology. Energy Audit is the key to a systematic approach for decision-making in the area of energy management. It attempts to balance the total energy inputs with its use, and serves to identify all the energy streams in a facility.

What are the four steps of an energy audit?

A systematic energy audit can be broken into four phases: planning, investigating, implementing and sustaining. Proactive facilities strive to continually improve energy efficiency by repeating these phases at regular intervals.

What is checked during an energy audit?

An energy auditor will take a look at your building from the outside. They’ll examine a variety of components, including windows, walls, and eaves, to see if they can spot any major issues causing leaks into or out of your home. The auditor will check out the attic (if you have one) to take a look at a few things.

How do you do a detailed energy audit?


  1. Step 1: Building and Utility Data Analysis.
  2. Step 2: Walk-Through Survey.
  3. Step 3: Baseline for Building Energy Use.
  4. Step 4: Evaluation of Energy-Saving Measures.

What are the three types of energy audit?

There can be three types of energy audits [24], and they are walk-through energy audits, target energy audits, and detailed energy audits.

How many types of energy audits are there?

Two types of energy audits are available: a preliminary energy audit and a detailed energy audit. The type you choose will depend on your needs. Preliminary energy audit: This type of audit is simply a data-gathering exercise that offers a preliminary analysis.

What are energy audit instruments?

Industrial Sector

S.No. Name of the Instrument
1. Flue Gas Analysers
2. Temperature Indicators
3. Infrared Thermometers
4. Thermal Insulation scanner

How many phases does an energy audit have?

Detailed energy auditing is carried out in three phases: Phase I, II and III.

How do you determine energy efficiency?

Conduct a home energy audit yourself and prioritize your energy efficiency upgrades.

  1. Locate Air Leaks.
  2. Consider Ventilation.
  3. Check Insulation Levels.
  4. Inspect Heating and Cooling Equipment.
  5. Lighting.
  6. Appliances and Electronics.
  7. Your Whole-House Plan.
  8. Professional Home Energy Assessment.

What are the four main elements comprising the monitoring and targeting?

Energy Monitoring and Targeting: Defining monitoring & targeting, Elements of mon- itoring & targeting, Data and information-analysis, Techniques -energy consumption, Production, Cumulative sum of differences (CUSUM).

What is the first step of detailed energy audit?

1. Data collection. Collecting the business energy audit data is the first step in the energy audit of existing buildings. The auditor takes into account criteria such as the surface area of the buildings, the energies used by the company and the uses of its occupants, and the energy bills.

How many stages are there in energy audit?

Detailed energy auditing is carried out in three phases: Phase I, II and III. Industry-to-industry, the methodology of Energy Audits needs to be flexible. A comprehensive ten-step methodology for conduct of Energy Audit at field level is pre- sented below.

What is an energy audit?

energy audit is a list of recommended energy efficiency measures (EEMs), their as-sociated energy savings potential, and an assessment of whether EEM installation costs are a good financial investment. Types of Energy Audits Energy audits typically take a whole building approach by examining the building

What is the scope and level of economic evaluation for energy audit?

Prior to conducting an energy audit, the scope and level of economic evaluation should be pre-defined. Energy Audit is conducted to determine ways to reduce energy consumption per unit of product output and/or to lower operating costs for facilities.

What is included in a preliminary energy use analysis?

All three levels of audits require a Preliminary Energy Use Analysis which involves the following: a site visit to assess the building and energy consuming equipment analysis of the utility bills to determine whether savings can be had by changing the utility rate a summary of utility bill data

Is ASHRAE level energy audit worth it?

A rightly sized energy audit will provide the right balance between audit cost and value of the audit. The ASHRAE Level audits are recommendations. They are not law. You can always pick and choose what they want and don’t want in the audit. What is most important is that you get value for your money.
