5.1 Calculation Principle
5.1.1 production and energy consumption
Production of various kinds of energy use is energy for productive activities, including primary energy (coal, crude oil, natural gas, etc.), quadratic
Source (electricity, heat, petroleum products, coke, gas, etc.), energy working fluid (water, oxygen, compressed air, etc.) and waste heat resources, including energy and energy
Working fluid within the enterprise storage, conversion and measurement of supply (including export) in losses, excluding life energy infrastructure projects, approved
Energy.
Corporate life with an energy enterprise system refers to the dormitory, the school, culture and entertainment, healthcare, business services and other aspects of early childhood education and childcare
Use energy. Not including the workshop, administration lighting, heating, cooling, bathing and other energy.
5.1.2 Production Enterprise reporting period energy consumption
During the reporting period the enterprise produced energy consumption There are three calculation methods.
Method one. enterprise reporting period, the production of energy companies to purchase the amount of energy consumption = beginning inventory amount of energy - the energy export business
Amount - Enterprise infrastructure projects energy consumption - Living with energy companies - ending stocks for the amount of energy;
Method two. enterprise reporting period, the production of energy consumption = energy consumption enterprises of various production processes and subsidiary auxiliary energy production system
The amount of internal energy conversion losses;
Method three. enterprise reporting period, production of the integrated enterprise energy consumption = energy consumption of the product and.
5.1.3 Measurement of the amount of physical energy
Measurement of the amount of physical energy should comply with "People's Republic of China Measurement Law" and the GB 17167.
5.1.4 Principles variety of energy (including energy production and energy consumption of the working fluid) and the unit of measure conversion
5.1.4.1 unit energy consumption by kg of standard coal (kgce) or tons of coal equivalent (tce), said to be its low (bits) equal to the amount of heat
