4 Energy efficiency evaluation levels .
The energy efficiency rating of the lighting system is divided into 3 levels. Level 1 is the highest and is the leader level. The total score of energy efficiency evaluation of lighting systems of each level shall not be lower than that specified in Table 1.
Table 1 Energy efficiency rating of lighting systems
5 Evaluation procedures
5.1 Determining the evaluation scope
Before the evaluation, the list of lighting facilities involved in the evaluation shall be clarified, the scope of the evaluation shall be determined and written records shall be formed.
The scope of evaluation shall be determined by the operator or manager of the lighting system. The scope of the evaluation shall be determined jointly by the operator or manager of the lighting system.
The scope of a lighting system usually includes the luminaires and the control management system. The luminaire in a lighting system may be either an integrated luminaire or a luminaire consisting of a power supply. A luminaire can be either an integrated luminaire or a luminaire consisting of a power supply, light source/module, etc. The control management system usually consists of a single lamp controller sensor installed inside or outside the luminaire, a centralised controller outside the luminaire (also known as 'cabinet control'), control software and other components.
5.2 Determining the evaluation period
The period of time involved in the evaluation (evaluation cycle) should be defined before the evaluation. The period of normal operation of the lighting system should be selected as the evaluation period.
5.3 Collecting information
Before the evaluation, the relevant design, selection, operation and management documents should be collected according to the defined evaluation scope and evaluation cycle. Technical and management documents, including but not limited to:
a) Basic information of the system:
b) System design information;
c) Project bidding documents. Energy saving assessment and other special reports;
d) Equipment inventory, including the list of equipment and facilities within the system boundary;
e) Relevant tests, evaluations. Verification reports;
f) operation procedures. Operation records, maintenance records. Energy consumption statistics, historical lighting hours and other technical data;
g) personnel qualifications, training records, etc:
h) Documents proving energy saving renovation and others.
When the information collected does not fully prove the actual operation of the system, on-site measurements should be carried out.
5.4 Evaluation implementation
5.4.1 The operator or manager of the lighting system shall ensure that the system operates in accordance with safety, energy conservation. Environmental protection and other laws, regulations and mandatory standards requirements.
5.4.2 The evaluation agency or personnel shall evaluate and score each indicator in accordance with the lighting system energy efficiency evaluation index system and the assignment method given in Appendix A from six aspects, including equipment and facilities, system design, energy-saving monitoring, operation control, energy-saving renovation and management measures, and sum up the scores of each indicator to obtain a comprehensive quantitative score for the lighting system energy efficiency evaluation.
5.4.3 The evaluation agency or personnel shall review and check the design documents, statistical reports, original records, declaration documents. 5.4.3 The evaluation agency or person shall give the score by reviewing and checking design documents, statistical reports, original records, declaration documents, analysis/testing reports, third party certification and other supporting materials. The rating may also be given through interviews, field surveys, sample surveys. The evaluation information can also be collected by means of interviews, field surveys, sample surveys, field tests, etc.
5.4.4 The evaluation agency or person may combine the score with the results to give recommendations for system optimisation and modification. Recommendations for energy saving measures to strengthen management.
5.5 Preparation of evaluation report
The evaluation report shall include the following:
a) A brief description of the evaluation process;
b) Evaluation implementation team;
c) Scope of the evaluation:
d) List of information collected for the evaluation;
e) A description of the score sheet and supporting materials:
f) Energy efficiency rating;
g) Recommendations for energy efficiency measures;
h) Other annexes.
