Category: Technology

Abstract:This paper Provides customers/ industrialist with recommendations which will increase the comfort, health, safety and prolong the durability of the assets. Aware owner may conduct preliminary energy audit by observing daily/ monthly energy consumption and make a list of concern area so when an auditor, come for auditing the management is ready /prepared to get focus on the major problem. Become more aware, after energy audit compare calculations for savings have been identified with the actually achieved generally savings are determined on higher side. Further some auditor use the high cost of electricity to calculate energy savings. This can give a false picture of the actual savings and may result in over-optimistic savings predictions. This paper also provides how to calculate the exact values from the electricity bills, and how to use these values. Finally, the discuss is on the several daily use of energy -savings measures which energy auditors frequently consider. Energy Audit is to determine ways to reduce energy consumption per unit of product output or to lower operating costs. Energy Audit provides a \"bench-mark\" (Reference point) for managing energy in the organization and also provides the basis for planning a more effective use of energy throughout the organization. SAFETY We also conduct Health Assessment and Safety Audits of existing plants to minimize the incidences of accidents. We continuously strive to improve our safety practices and we dedicate significant time and effort to ensure that we provide a safe work environment for our employees. HOW TO CONDUCT WALK-THROUGH AND PROCESS AUDIT Conduct Meeting Create Team Collect Plant Data Conduct Field Investigation Create Equipment Inventory And Distribution Of Demand And Energy Develop ECMs and Implementation Strategies.

INTRODUCTION
First, introduced about energy audit. Energy means is the capacity of a system to do work. All movements are made with the help of energy, Energy can be found in a number of different forms such as Chemical energy, electrical energy, heat (thermal energy), light (radiant energy), and mechanical energy. The most general definition of an audit is an evaluation of a person, organization, system, process, project or product. Audits are performed to ascertain the validity and reliability of information, and provide an assessment of a system's internal control. The goal of an audit is. to express an opinion on the person/organization/system etc. under evaluation based on work done on a test basis. Energy audit is the key to a systematic approach for decisionmaking in the area of energy management. It attempts to balance the total energy inputs with it use, and serves to identify all the energy system in a facility. An energy audit is an inspection, survey and analysis of energy flows for energy conservation in a building, processor system to reduce the amount of energy input into the system without negatively affecting the output.

TYPE OF ENERGY AUDIT:-
One way to identify method to improve energy efficiency, there are many types of energy audits that can be performed at any field. The term energy audit is commonly used to describe a broad spectrum of energy studies ranging from a quick walk-through of a facility to identify major problem areas to a comprehensive analysis of the implications of alternative energy efficiency measures sufficient to satisfy the financial criteria of sophisticated investors. Three common audit programs are described in more detail below. 1) Preliminary Audit (Walk Through Audit) The preliminary audit alternatively called a simple audit, screening audit or walk-through audit, is the simplest and quickest type of audit. Sample readings and measurements are taken, including power, lighting level, thermal comfort are recorded. EMO (Energy Management Opportunities) and findings are provided in written report for implementation by your management team. A walk-though audit as its name implies involves a walking tour of the premises, where the auditor inspects the energy related systems. Energy data if available for one or more years would be requested for analysis,. Advantages of the walk-though energy audit include faster results and lower cost. EMO's can be implemented quickly using the proven technology. During the walk-through audit if the auditor unable to identify EMO (Energy Management Opportunities) then benefit from a comprehensive audit is recommended, which is more sophisticated audit for a specific part of a system or process. 2) General Audit (Modified Audit) This type of audit is not warranted for the majority of installations. The standard energy audit is more detailed than the walk-through audit; more data is collected and analysed. Being more through less likely to overlook more complex EMO's as known as a standard energy audit. This audit involves a longer more detailed investigation than the walk-through audit. This type of audit will be able to identify all energy conservation measures appropriate for the facility given its operating parameters. A detailed financial analysis is performed for each measure based on detailed implementation cost estimates; site-specific operating cost savings, and the customer's investment criteria. Sufficient detail is provided to justify project implementation. 3) Investment-Grade Audit (or Full Audit) The investment grade energy audit is the most sophisticated of all the type of energy audit. It requires detailed energy modelling, analysis of the facility, and energy meter data for several years the investment-grader audit alternatively called a comprehensive audit, detailed audit, maxi audit, or technical analysis audit, expands on the general audit described above by providing a dynamic model of energy use characteristics of both the existing facility and all energy conservation measures identified.

NEED FOR ENERGY AUDIT
The Energy Audit would give a positive orientation to the energy cost reduction, preventive maintenance and quality control programs which are vital for production and utility activities. Such an audit programmer will help to keep focus on variations, which occur in the energy costs, availability and reliability of supply of energy, decide on appropriate energy mix, identify energy conservation technologies, retrofit for energy conservation equipment etc. Energy Audit will help to understand more about the ways energy and fuel are used in any industry, and help in identifying the areas where waste is occurring and the scope for improvement exists. The primary objective of Note:-electricity utility do not impose penalty up 90%power factor however incentive is given for power factor above 95%.by providing capacitor bank loading on electrical system get reduce due to reduction in reactive power.

ECONOMIC FORMULAS
Simple Payback on an Investment (Years) = Net Installation Cost ($) ÷ Annual Energy Savings ($) 5-Year Cash Flow ($) = 5 Years - Payback (Years) x Annual Energy Savings ($) Simple Return on Investment (%) = [Annual Energy Savings ($) ÷ Net Installation Cost ($)] x 10

SOME OTHER RECOMONDATION
Further it is suggested that work be carried out Considering the potential processes to be used by growing industries. Select ballasts and lamps carefully with high power factor and long-term efficiency in mind. Consider painting the walls a lighter color and using less lighting fixtures or lower wattages. Use task lighting and reduce background illumination Use energy-efficient motors where economical. Check for undervoltage and over-voltage conditions. Balance the three-phase power supply. (An imbalanced voltage can Demand efficiency restoration after motor rewinding.(If rewinding is not done properly, the efficiency can be reduced by 5 - 8%) .Recycle water, especially if sewer costs are based on water consumption.

Tips/Risk in Developing and Successful and Cost Effective Energy Conservation Program
 

• Water and Electric are the most common input in the process focused conservation of these two input will save cost and option for reuse of water must be explore.
• Avoid wastages.
• Recommended changes in the process may not be well received if they affect wastewater effluent quality or product quality is mandated; energy efficiency is not.
• Recommended changes may require more operator attention, which could require additional labour costs and training.
• Recommended capital cost for the change may be difficult to budget.
• Capital cost may be difficult or impossible to finance.
• They may be a heavier focus on the agency capital costs versus OandM saving such as energy.

CONCLUSION
With the help of this paper, we have concluded, A Energy audit increases the productivity of organization. Energy audit helps to increase output of any industry and decreases cost of production without scarifying the efficiency. Energy audit provides batter stability to the industry or organization then the statutory audits.
