?What is an energy audit
Definition of energy audit: Energy audit is a set of measures that are used to identify, how the amounts and situations of energy consumption in an activity or process, and during which energy saving opportunities and facilities are identified and evaluated.
Energy audit in the building
The energy audit in the building includes a detailed examination in order to determine how the energy consumption of the unit, estimate the initial costs and finally provide a proposed plan to reduce the energy consumption of the building. According to the general definition of building energy audit, various methods are provided by specialists and experts to implement energy audit in the building.
Based on this, in order to avoid arbitrary energy audits, it has been tried to prepare building energy audit guidelines and make them available to auditors, and by using them, energy audits in buildings can be conducted in a coordinated and targeted manner to achieve the desired result. It should be noted that the energy audit in the building is a function of the auditor's scientific level, experience, awareness and knowledge of new technologies and the latest energy optimization methods, and therefore energy auditors may provide different solutions to reduce the energy consumption of a building, but more importantly It is that the methods of recording the basic information of the building and performing the relevant calculations are the same, so that the same conclusion regarding the energy consumption of that building can be presented.
Energy audit in industry sector
Improving energy consumption and improving the quality level of consumption in an industrial unit, considering that the amount of energy required to produce a product is specified in the design, starts with reducing losses and then improving the process, load and energy management, increasing the efficiency of equipment by making changes and replacing equipment. , increasing thermal recovery and recycling wasted mass flows, etc. continues.
The starting point for achieving the optimal state of consumption in an industrial unit is an energy audit. Energy audit in an industrial unit is a general title that can include various concepts according to the type of service provided, but generally refers to the set of activities carried out in an industrial unit that lead to determining the quantitative and qualitative status of consumption. energy in the unit and providing methods to improve the existing conditions is referred to as energy audit. Depending on the method considered for energy audit, the following main goals are considered in such projects:
Identifying the amount and manner of energy consumption and determining energy consumption intensity coefficients (system review)
Providing solutions to reduce energy consumption and intensity (system treatment)
Compilation of the activities of the single energy group to check and control the state of energy consumption (maintenance of the system
It is obvious that achieving these goals in each industrial unit, according to the various parameters and existing determining conditions, requires its own planning and studies and requires a complete understanding of the unit. The auditor's sufficient understanding of the process and method of producing the product and the knowledge of the key and high-use points in its production process will make the auditor able to achieve the set goals faster, better and more completely based on this knowledge. Also, accurate determination of consumption conditions is obtained by performing field activities and attending the unit and performing the necessary measurements, which require accurate planning and implementation of the program in short and appropriate time conditions and full understanding of the capabilities of different measuring devices. Diagnosing and determining the effectiveness of energy saving opportunities also requires full identification of process conditions, correct understanding of existing conditions and potentials, and determination of mutual effects of proposed changes in working conditions.
Energy consumption index
For each specific industry, a parameter called Specific Energy Consumption or SEC is defined and calculated. The energy consumption index shows the amount of energy consumed per unit of manufactured product. For example, the energy used to produce one ton of steel or aluminum or one meter of fabric shows the energy consumption index of each of these products. The mentioned index is calculated for both domestic and industrialized countries. Some of these indicators are known as international indicators.
Types (levels) of energy audit
Checking and measuring energy consumption (approximate estimate of consumption, potentials and possibilities of saving through review and visual observation)
Preliminary (initial) energy audit (initial estimate of energy consumption) or short-term energy audit
Comprehensive energy audit (comprehensive) Comprehensive estimate of energy consumption with full details
