Electrical Energy Audit

ENERGY AUDIT OF INDUSTRIAL, COMMERCIAL AND RESIDENTIAL

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. It quantifies energy usage according to its discrete functions.

As per the Energy Conservation Act, 2001, Energy Audit is defined as “the verification, monitoring and analysis of use of energy including submission of technical report containing recommendations for improving energy efficiency with cost benefit analysis and an action plan to reduce energy consumption”.

In general, Energy Audit is the translation of conservation ideas into realities, by lending technically feasible solutions with economic and other organizational considerations within a specified time frame.

 

The energy audit is sometimes called an energy survey or an energy analysis, so that it is not confused with a financial audit.

The energy audit is a positive experience with significant benefits to the facility.

The term “audit” should be avoided if it clearly produces a negative image in the mind of a particular business, organization, or individual.

 

ENERGY AUDIT CONSULTANCY BY TEAM SHADOW ENERGY

A team of energy professionals from Nascon conducts Energy Audits of various Industrial, Commercial, Building, Residential facilities to reduce their energy consumption and help in proper maintenance of their electrical as well as thermal systems for energy efficiency, energy conservation, energy audit and management, electrical energy audit.

 

BASIC COMPONENTS OF AN ENERGY AUDIT

The audit process starts by collecting information about a facility’s operation and about its past record of utility bills. This data is then analysed to get a picture of how the facility uses – and possibly wastes – energy, as well as to help the auditor learn what areas to examine to reduce energy costs. Specific changes – called Energy Conservation Measures (ECM’s) –are identified and evaluated to determine their benefits and their cost effectiveness.

These ECM’s are assessed in terms of their costs and benefits, and an economic comparison is made to rank the various ECM’s.

Finally, an Energy Action Plan is created where certain ECM’s are selected for implementation, and the actual process of saving energy and money begins.

 

GOALS OF THE ENERGY AUDIT 

Clearly identify types and costs of energy use.

    Understand how energy is being used – and possibly wasted.

Identify and analyse more cost-effective ways of using energy

Improved operational techniques

New equipment, new processes or new technology

Perform an economic analysis on those alternatives and determine which ones are cost-effective for your business or industry.

TYPES OF ENERGY AUDITS

  1. Type I - also called walk-thru or checklist
  2. Type II - also called Mini-audit
  3. Type III - also called Maxi-audit
  4. Investment grade audit
  5. Master Audit

 

NINE MAJOR SYSTEMS TO CONSIDER

  1. Building Envelope
  2. HVAC System – people comfort
  3. Electrical Supply System
  4. Lighting
  5. Boiler and Steam System / Furnace and Ovens
  6. Hot Water System - domestic
  7. Compressed Air System
  8. Motors – that I can see
  9. Special Purpose Process Equipment
