1. Policy oriented judgment method

According to the national and local energy development policies and relevant planning, the energy consumption scheme of the project is analyzed and evaluated in combination with the natural conditions and energy utilization conditions of the project site

2. Standard specification comparison method

Analyze and evaluate the energy conservation standards and specifications that should be implemented in the project, especially the mandatory standards, specifications and terms should be strictly implemented. It is applicable to the evaluation of energy consumption scheme, building thermal design scheme, equipment selection, energy-saving measures, etc. of the project. The energy consumption scheme of the project shall meet the provisions of relevant standards and specifications; The architectural design of the project, the thermal index of the enclosure structure, the indoor design temperature of heating and air conditioning, etc. shall meet the provisions of relevant standards; The selection of equipment shall meet the provisions of relevant standards and specifications on 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

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 specified project energy consumption access standard and the advanced level of the same industry at home and abroad. It is applicable to the selection of industrial project process scheme, the effect of energy-saving measures and the calculation and evaluation of energy consumption. If the specified energy consumption admittance standard cannot be met, the energy consumption process of product production shall be comprehensively analyzed to find out the main problems and put forward improvement suggestions.

5. Unit area index method

Civil building projects can calculate energy consumption indicators per unit area according to different use functions, and compare with energy consumption indicators of similar projects. If the difference is large, it indicates that there are problems in the scheme design or energy consumption system of the proposed project. Then, a detailed analysis can be carried out 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 various energies, and the quantity balance between consumption and effective utilization and loss. The energy balance analysis is a comprehensive and systematic analysis of the energy consumption of the project according to the results of the energy balance of the project, so as to clarify the energy utilization efficiency of the project, the size, distribution and causes of the energy loss, so as to help determine the energy conservation goals and find practical and feasible energy conservation measures.

The above assessment methods are the main general methods for energy conservation assessment, which can be selected and used according to the characteristics of the project. Other evaluation methods can also be selected according to needs in terms of specific energy use scheme evaluation, energy consumption data determination, and energy conservation measures evaluation.
