Scope

GB/T 41013-2021 is the English-translated version of 电机系统能效评价.

GB/T 41013-2021 sets out how to evaluate the energy performance of a motor system and give it an energy efficiency level.

It covers stable-running systems made up of small and medium-sized electric motors below 1000 kW, a single driven machine - fan, pump or air compressor - and its control device, transmission and pipe network; more complex systems and motor system stations can use it as a reference.

The standard defines the efficiency levels and the procedure, from the documents collected to the scoring carried out against the index system and scoring method of normative Annex A, where any item without supporting evidence scores zero, and it lists what the evaluation report must contain, including energy-saving recommendations.

It is intended for system operators and evaluation bodies. It was issued on 31 December 2021 and has applied since 1 July 2022.

5 Evaluation procedures

5.4 Evaluation implementation

5.4.1 The operator or management party of the motor system shall ensure that the operation of the system complies with the requirements of laws, regulations and mandatory standards such as safety, energy saving and environmental protection.

5.4.2 The evaluation agency or personnel shall evaluate the energy efficiency of the motor system according to the scoring index system and scoring method given in Annex A and give quantitative results.

5.4.3 The evaluation agency or personnel shall give scores by consulting and checking design documents, statistical reports, original records, declaration documents, analysis/test reports, relevant third-party certification certificates and other supporting materials. Relevant evaluation information can also be collected through discussions, field investigations, sample surveys, and field tests. Each scoring result shall be supported by documented information. The score for the scoring item without corroborating materials is 0.

5.4.4 The evaluation agency or personnel can give suggestions on energy-saving measures in terms of system optimization and transformation, strengthening management based on the scoring results.

5.5 Preparation of evaluation report

The content of the evaluation report shall include:

a) A brief description of the evaluation work process;

b) Evaluation of the implementation team;

c) Scope of evaluation;

d) Evaluation of the list of information collected;

e) Description of the score sheet and the certified materials;

f) Energy efficiency rating and comprehensive score;

g) Recommendations for energy saving measures; […]
