1, policy-oriented judgment method
According to the national and local energy development policies and related planning, combined with the natural conditions and energy utilization of the project location, the energy consumption scheme of the project is analyzed and evaluated.
2, standard control method
The energy-saving standards and specifications that should be implemented in the analysis and evaluation project, especially the mandatory standards, specifications and clauses, should be strictly implemented. It is suitable for the evaluation of energy consumption scheme, building thermal design scheme, equipment selection and energy-saving measures of the project. The energy consumption scheme of the project shall comply with the provisions of relevant standards and specifications; Architectural design of the project, thermal index of envelope structure, indoor design temperature of heating and air conditioning, etc. Should comply with the provisions of the relevant standards; Equipment selection should meet the requirements of relevant standards and specifications for performance coefficient and energy efficiency ratio; Whether applicable energy-saving measures have been taken in accordance with relevant standards and specifications.
3, expert experience judgment method
Using the professional experience, knowledge and skills of experts, through intuitive empirical analysis to make judgments. It is suitable for the selection of empirical data in energy consumption scheme, technical scheme and energy consumption calculation of the project and the evaluation of energy-saving measures. According to the relevant majors involved in the project, organize relevant experts to analyze and evaluate whether the energy consumption scheme adopted in the project is reasonable and feasible and whether it is conducive to improving energy utilization efficiency; Analyze and judge whether the value of empirical data in energy consumption calculation is reasonable and reliable; Analyze and evaluate whether the energy-saving measures to be adopted in the project are applicable and feasible.
4, product unit consumption comparison method
According to the energy consumption of the project, the energy consumption index of the project unit product is compared with the energy consumption access standard stipulated by the project and the advanced level of the same industry at home and abroad. It is suitable for the selection of industrial project process scheme, the effect of energy-saving measures and the calculation and evaluation of energy consumption. Can not meet the prescribed energy consumption access standards, it should be a comprehensive analysis of the energy consumption process of product production, find out the main problems, and put forward suggestions for improvement.
5, unit area index method
Civil construction projects can calculate the energy consumption index per unit area according to different use functions and compare it with similar projects. If there is a big difference, it shows that there are problems in the scheme design or energy consumption system of the proposed project, and then detailed analysis can be made according to the energy consumption index per unit area of different varieties to find out the problems in the energy consumption system and put forward suggestions for improvement.
6, energy balance analysis method
Energy balance refers to the energy balance of the proposed project, including the balance of income and expenditure of all kinds of energy, the quantitative balance of consumption and effective utilization and loss. Energy balance analysis is a comprehensive and systematic analysis of the energy consumption of the project according to the energy balance results of the project, so as to clarify the energy utilization efficiency of the project, the size, distribution and reasons of energy loss, so as to help determine the energy-saving goals and find feasible energy-saving measures.
The above are the main methods of energy-saving assessment, which may change slightly according to the actual situation, but in general, different assessment methods should be selected according to different situations. I hope the above summary will be helpful to those in need.
