GB/T 34913-2017Classification and presentation of civil building energy use (English PDF)

2.1 Building energy consumption

Operating energy consumption during use of the building, including inputs from outside, for the maintenance of the building environment (eg heating, cooling, ventilation and lighting, etc.) and

Various types of building activities (such as office, cooking, etc.) energy use, does not include building materials manufacturing and construction of energy. Building energy consumption should be eliminated

Consumption of electricity, fossil fuels and other physical quantities, and indicate the type and quantity of energy; but also to further the different types of energy

Unified conversion.

2.2 The energy coefficient

For the energy of the exergy and the number of energy ratio, the value of 0 to 1 between. The higher the energy grade, the greater the corresponding energy coefficient.

3 building energy consumption by the use of classification and index form 3.1 The boundary of building energy is located at the entrance of the building (Figure 1), corresponding to the power, fuel, cold /

Heat medium and other energy, that is, building energy consumption.

Notes 1. Building energy consumption excludes renewable energy (non-commodity energy) provided by solar energy installed on buildings, wind energy utilization equipment, etc.

Note 2. Electricity and fuel consumed by renewable energy systems (eg, electricity consumed by pumps in solar systems) are included in the building energy consumption.

Note 3. If secondary products (such as electricity, hot water, steam, cold water, etc.) produced in the building and produced by the transmission and distribution of cooling/heating medium energy systems are used in addition to their own use,

Building, then according to the fire distribution method described in Chapter 4 accounting for the secondary energy supply to other buildings corresponding to the input energy, and this input energy from

Deducted from the building energy consumption.

Note 4. Building energy consumption excludes energy storage charging equipment used for equipment outside the building.

See Appendix A for an example of building energy consumption.
