1. Policy-oriented judgment method
An analysis and evaluation of the project's energy use program based on the national and local energy development policies and related planning, combined with the natural conditions of the project site and energy use conditions.
2. Comparison of standards and norms
Analysis and evaluation of energy-saving standards and norms that should be implemented for the project, especially the mandatory standards, norms and provisions should be strictly implemented. Applicable to the project's energy program, building thermal design program, equipment selection, energy conservation measures and other evaluation. The project's energy use program shall meet the provisions of relevant standards and norms; the project's building design, thermal indexes of the envelope, heating and air-conditioning indoor design temperatures, etc. shall meet the provisions of relevant standards; the selection of equipment shall meet the provisions of relevant standards and norms on the performance coefficients and energy-efficiency ratios; and whether or not applicable energy-saving measures have been taken in accordance with the provisions of relevant standards and norms.
3. Expert Experience Judgment Method
The judgment method of using the experience, knowledge and skills of experts in professional aspects through intuitive experience analysis. Applicable to the project energy program, technical program, the value of empirical data in the calculation of energy consumption, the evaluation of energy-saving measures. According to the relevant professions involved in the project, the corresponding experts are organized to analyze and evaluate whether the energy-use scheme adopted by the project is reasonable and feasible, and whether it is conducive to improving the efficiency of energy use; analyze and judge whether the value of the empirical data in the calculation of energy consumption is reasonable and reliable; and analyze and evaluate whether the energy-saving measures to be selected for the project are applicable and feasible.
4. Comparison method of unit product consumption
Based on the project's energy consumption, the project's energy consumption per unit of product is analyzed by comparing the project's energy consumption indexes with the stipulated project's energy consumption access standards and the international and domestic advanced level of the same industry. Applicable to the selection of industrial project technology programs, the effect of energy-saving measures and energy consumption calculation evaluation. If it fails to meet the prescribed energy consumption access standards, it should comprehensively analyze the energy-using process of product production, find out the main problems and put forward suggestions for improvement.
5. Unit area index method
Civil building projects can be calculated according to the different functions of the unit area of energy consumption indicators, compared with the energy consumption indicators of similar projects. If the difference is large, it indicates that the proposed project program design or energy system and other problems, and then can be analyzed in detail according to the varieties of energy consumption indicators per unit area, to find out the problems of the energy system and put forward proposals for improvement.
6. Energy balance analysis
Energy balance is the proposed project as the object of the energy balance, including a variety of energy income and expenditure balance, consumption and effective use and loss of the number of balance between. Energy balance analysis is based on the results of the project energy balance, the project energy situation for a comprehensive and systematic analysis, in order to clarify the project energy efficiency, energy loss size, distribution and loss of the reasons, in order to determine the energy-saving goals, looking for practicable energy-saving measures. The above assessment methods are the main methods common to energy-saving assessment, and can be selected and used according to the project characteristics. In the specific energy program assessment, energy consumption data to determine the evaluation of energy-saving measures can also be selected according to the need to use other assessment methods.
7. Adhere to the energy-saving assessment and review of the front
The development and reform departments will not approve or endorse fixed asset investment projects that do not obtain approval for energy-saving review and submit energy-saving registration forms according to regulations.
