GB/T 40498-2021General principles of drafting energy consumption norm standards for public institutions (English PDF)

3.1 Comprehensive energy consumption

During the operation of a public institution, the sum of the converted actual amount of energy consumed in a calendar year according to the prescribed calculation method.

Note: The unit of comprehensive energy consumption is kilogram standard coal (kgce). [Source: GB/T 2589-2020, 3.5, with modifications]

3.2 Amount of energy consumer

In a calendar year, the daily average number of energy consumers in a public institution.

3.3 Comprehensive energy consumption per person

During the operation of a public institution, the ratio of comprehensive energy consumption to the amount of energy consumer in a calendar year.

Note: The unit of comprehensive energy consumption per capita is kilogram standard coal per person (kgce/person).

3.4 Conventional energy consumption per unit building area

During the operation of a public institution, in a calendar year, the ratio of the sum of standard coal that is converted from the physical quantities of various energy consumption other than vehicle energy consumption to the building area.

Note: The unit of energy consumption per unit building area is kilogram standard coal per square meter (kgce/m2).

3.5 Heating energy consumption per unit heating building area

During the operation of a public institution, in a heating period, the ratio of the sum of standard coal that is converted from the physical quantity of energy consumption for heating to the heating building area.

Example: The calendar year is 2021, for the heating consumption, the relevant information of the heating period from the winter of 2020 to the spring of 2021 is selected.

Note: The unit of heating energy consumption per unit heating building area is kilogram standard coal per square meter (kgce/m2).

3.6 Non-heating energy consumption per unit building area

During the operation of a public institution, in a calendar year, the ratio of the sum of standard coal that is converted from the physical quantities of various energy consumption except heating energy consumption and vehicle energy consumption to the building area.

Note: The unit of non-heating energy consumption per unit building area is kilogram standard coal per square meter (kgce/m2).

3.7 Constraint value

Under the premise of ensuring the normal operation of a public institution, the allowable limits of relevant energy consumption indices.

3.8 Reference value

A.2 Calculation method for the amount of energy consumer in an educational institution

The amount of energy consumer in an educational institution should be composed of in-staff teachers and personnel, handymen, support personnel, registered students, and outsiders. The winter and summer vacations of the corresponding personnel shall be deducted when calculating the daily average amount of energy consumer. For outsiders, the daily average amount of energy consumer should be calculated according to the duration of stay in the educational institution. An example is as follows.

The amount of energy consumer in a school is as follows:

a) In-staff teachers and personnel: The number of people is 400, of which 300 people do not work in the school during winter and summer vacations, and the remaining 100 people need to continue to work on campus during winter and summer vacations;

b) Handymen and support personnel: The number of people is 240, of which 175 people do not work in the school during winter and summer vacations, and the remaining 65 people need to continue to work on campus during winter and summer vacations;

c) Registered students: The number of people is 3,000, of which 2,500 are not at school during winter and summer vacations, and the remaining 500 people are not at school only during winter vacation;

d) Outsiders:

--- Meeting 1: The number of participants is 3,000, and the meeting time is 2 days;

--- Meeting 2: The number of participants is 5,000, and the meeting time is 3 days.

Through the above description, the calculation of the amount of energy consumer in this school can be summarized according to Table A.2: […]
