Whether on business or for the individual, "green" at work and in life are increasing in the proportion. Millennials mind the environment and public welfare, hoping to join the green business, glue stick environmental protection and renewable energy into quite a lot of attention; enterprises are increasingly able to accept this concept, and energy consumption not only generate benefits in profit, more bring positive publicity to the enterprise image, why not?
The state policy in energy saving, environmental protection, also increasing tilt,glue gun the advent of the financial crisis is accelerating stressed its importance. Energy conservation is a big market for energy auditors and energy audits will gradually increase the demand for India in 2004-2006, approximately 5,000 trained energy auditors. Now, we want to lead you to understand an important part in energy saving projects: energy audit.
What is Energy Audit?
Energy audit is the use of energy utilization study accounting business evaluation methods, energy use per unit of energy utilization for quantitative analysis, using units of energy efficiency, consumption levels, economic and environmental effects of energy audit, monitoring, diagnosis and evaluation to seek energy-saving potential and opportunities. Energy audits are generally responsible for the sector and using units of energy audit agreement or contract entered into to determine the objectives and content.
Energy audit do?
For the provision of energy services companies, if borrowing "pre", "sale", "sale" service concept of analogy, then, energy audits or "pre", a process that occurs in energy-saving projects signed with the client Contract ago, only for the energy audit, where the user needs to know the energy saving, energy saving how much space, what kind of energy-saving measures can bring the user an acceptable return on investment requirements. Energy audit is mainly related to technical issues, you need energy service companies and customers with the completion. Energy Auditors need to talk with the customer to use more energy situation, under the leadership of the customer to view the scene with equipment operation, collection of relevant data and information necessary tools and equipment needed to take measurements; according to data obtained and measured data to calculate the equipment and systems which can save, how much money can be saved, by what means can save and budget for energy-saving measures the amount of investment. Through data analysis and field survey results, issued by the energy audit reports, work out a comprehensive energy plan submitted to the customer. Make a simple analogy, the energy audit is like a doctor's diagnostic process, that can improve the problem, a prescription; and customers to accept payments if the medication is a contract.
Enterprises in general, not just set up a job to do preliminary energy audit this one. Energy audit done, if the customer is willing to accept the program of energy conservation construction, reconstruction, these construction and renovation progresses, the effect of the follow-up and reach, are measured validation, the content of this work is similar to "sale."
How to Start Energy Audit?
Do energy audits of experience required is very high, university graduates is difficult to achieve this standard. Because the energy audit need to see the scene, based on experience and space for energy-saving potential, if the lack of experience, then do not know where to look on, do not know what data the test. Some places, such as energy-saving system has done well, but spent a large effort to test, it is a waste. In this case, the university graduates did not run through several on-site, it is difficult to determine, and therefore need a lot of time to get started, and explore the rules and doorways. From the working background, the general energy audit done, at least 3-5 years relevant work experience; from academic background, the need to at least degree, HVAC, heat and power, electrical engineering can join.
The key point of the energy audit?
① heart scale experience is king.
Energy audit is mainly based on the experience of engineers, the site run more and do more projects, get more experience, can be very adept at the scene to determine which have the potential energy and space, grasp the key points, thus further to do specific tests and data analysis.
Do energy audit to understand the energy systems used inside the building, learn about their temperaments, these systems have their own indicators, such as refrigeration system to produce a ton of cold energy, needs to consume many kilowatts. Head to a steelyard in the heart, to what constitutes well-condition, it is efficient. With this steelyard later, you can determine how much energy space. These are to experience a lot of sites, familiar with the operating characteristics of many devices can achieve.
② a "special" and more able to maintain the updating of knowledge.
Energy audit to understand the multi energy system. Of course, one can not very proficient in each system, but need to have a core area of expertise, as well as a comprehensive understanding of the other energy systems. General to do the project, not the building is the factory, of which the device surface are common, such as air-conditioning system, air compressor systems, boilers (steam distribution) system, to fully understand the performance of these devices and parameters. The line to keep the knowledge to do this update rate, because there are constantly new technology introduction.
③ master the return on investment, there are budget estimate capacity.
Energy audit of this "audit" is not a financial audit, but rather draw on the financial "audit" concept, considerable energy consumption details of each review, and audit tools are those measuring instruments, analytical tools. Energy audits are not required to master the audit of financial knowledge, but knowledge of engineering or economics must master. For example, simple payback (SPB), internal rate of return (IRR), return on investment (ROI) and other parameters of the calculation.
ROI is a conceptual thing, she'll know how it works. Can calculate the energy savings, will be counted investment budget estimate will be, for example in energy conservation programs, then add a control system to increase the number of controllers, sensors, what kind of features to achieve about how much money to spend. But the most important thing is the technical field, has the potential to find out where, how, how much can be sections, this is the key point.
④ training.
American Association of Energy Engineers AEE (Associationof Energy Engineers) energy management division registered CEM (CertifiedEnergyManager) is more popular in the industry, especially foreign. CEM training programs usually last 4-5 days, CEM received the title of one of the conditions required to participate in up to 4 hours of a professional examination. Study and examination of the contents are to do energy audits often meet the knowledge of the content such as energy audits and procedures. Knowledge of technology studied under a more comprehensive, such as air conditioning system, boiler system, air compressor system, energy-saving potential in buildings and factories in general applied to cover the nine major systems.
Difficulties encountered in the work experience?
We sometimes with customers to explain energy-saving measures and programs, the client based on production considerations, and the inherent mode of thinking, do not fully understand our measures and the benefits of the program. We now must convince him, why did you take this energy-saving measures. And customers in these areas, such as differences arise, do not too much to dwell on the details of the technical and technicbuyer to spend unnecessary effort, it is best to find the value of the contract energy management recognition, because they are valuebuyer, they are more concerned about can guarantee energy savings, return on investment is good.
Prospects for the future development of energy audit?
Some of the technology industry madman, willing to dig deep in professional practice, more people to a certain age, want to turn to management positions.
Energy Auditors, the average annual salary?
This business is in the high income in the industry, according to the different nature of business, salary levels will be so different from annual salary of more than 8 million people, the annual salary of foreign companies generally 10 million to hundreds of thousands of dollars.
