Scope
GB/T 35071-2018 is the English-translated version of 能量系统优化导则.
GB/T 35071-2018 is a Chinese national guideline on how to optimise an energy system as a whole rather than equipment by equipment.
It gives the basic principles, the sequence of steps and what each step must contain: dividing the system boundary, surveying the current situation and collecting representative data checked against material and energy balances, analysing the system's energy use and identifying energy-saving opportunities, drawing up and implementing an optimisation plan, and finally evaluating and maintaining the results.
The energy analysis relies on energy balance tables and network diagrams under GB/T 28751 and GB/T 28749 and on benchmarking against consumption limit standards, while savings are verified under GB/T 28750 and GB/T 32045.
It applies to energy users in all industries. It was issued on 14 May 2018 and has applied since 1 December 2018.

3 Terms and definitions
For the purposes of this document, the terms and definitions defined in GB/T 30716 apply.
4 Basic rules for energy system optimization
The energy system optimization shall follow the following principles.
a) In the case of meeting production needs, take the energy system as the optimization object as a whole; take into account economic benefits and […]
6 System boundary division
a) The boundary of each energy component or process within the system shall be clarified;
b) Boundary division shall ensure the controllability of energy system optimization within the boundary;
c) When different enterprises are involved in the same energy system optimization project, the system can be divided according to the boundary of the associated enterprise.
7 Status survey and data collection
7.1 Relevant materials and data for status survey and data collection shall meet the needs of system energy analysis and energy opportunity identification, optimization program development, implementation and performance evaluation.
7.2 The collected production and operation data shall be representative, timeliness and consistency.
7.3 Verify and correct collected data and material according to material balance, energy balance and relationship.
8 System energy analysis and energy saving opportunity identification
8.1 System energy analysis
System energy analysis shall include but is not limited to the followings.
a) From a system-wide perspective, perform energy analysis based on major energy-consuming equipment, processes, and units. Energy system energy balance table and energy balance network diagram can be drawn according to GB/T 28751 and GB/T 28749;
b) For the energy consumption of main products, procedures, based on energy consumption limit standards, carry out benchmarking analysis. In absence of corresponding specific standards, it shall be benchmarked with advanced levels at home and abroad;
c) Analyze the main energy medium and evaluate the rationality of energy utilization from the aspects of energy generation, storage, conversion, transportation, distribution, use and recycling. Conduct analysis of […]
