In the prior art, building energy consumption data is only compared and analyzed on different time dimensions for a single building. For example, the whole consumption of electric energy, gas energy and water energy of a building in the year is compared with that in the last year.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
Fig. 1 is a flowchart of a first embodiment of the method for identifying energy consumption of a building, and fig. 2 is a schematic diagram of a process for grouping buildings in the method for identifying energy consumption of a building.
As shown in fig. 1 and 2, in the present embodiment, the method of identifying energy consumption of a building includes the following steps S1, S2, and S3.
And S1, acquiring the environmental parameters and energy consumption data of each building in the building group.
Wherein the environmental parameters include: a natural environment parameter and/or a social environment parameter. The acquisition of the environmental parameters may be obtained through a specific acquisition terminal, or may be obtained by accessing a database, which is not limited in the present invention. For example, in this embodiment, each building is provided with an environmental parameter acquisition terminal, and the natural environment parameters are acquired by receiving the natural environment parameters acquired by the environmental parameter acquisition terminals in this step; the social environment parameters are obtained by calling the pre-stored social environment parameters from the database. Of course, the geographical location of the building, which is hereinafter referred to as the natural environment parameter, may be a static parameter, i.e. obtained by accessing a database. Meanwhile, the natural environment parameter and the social environment parameter are only one standard for dividing the parameters, and can be divided into a static parameter and a dynamic parameter, and can also be divided into a sensor parameter and a non-sensor parameter, which is not limited in the invention.
The natural environment parameters include: the indoor and outdoor air pressure value of the building, the indoor air quality value of the building and the indoor and outdoor carbon dioxide concentration value of the building.
The social environment parameters include: the administrative region to which the building belongs, the building state to which the building belongs, the building structure to which the building belongs, the completion time of the building, the type of energy used by the building, the energy use system of the building, the building area, and the number of people using the building. Wherein, administrative area includes: province, city, county (e.g., a certain province, a certain city, a certain county, a certain cell). The building state comprises: office buildings, hotels, residences, public places (museums, natatories, sports halls, etc.), factories, single villas, or rural yards. The building structure includes: glass curtain wall structures, brick concrete structures or reinforced concrete structures; the energy types comprise electric energy, gas energy, water energy, heat energy and cold energy. The energy use system of a building includes: air-conditioning refrigeration system, heating system, public lighting, elevator, office energy, residential energy, and production energy.
In this embodiment, each building is provided with an energy consumption data acquisition terminal, and this step acquires energy consumption data by receiving energy consumption data acquired by the energy consumption data acquisition terminals.
The energy consumption data includes: at least one of power consumption, water consumption, and gas consumption. Specifically, the energy consumption data includes: electricity, water, and gas consumption of each room of each floor in each building. More specifically, the energy consumption data is subdivided, and the energy consumption data includes: power consumption and water consumption of the refrigeration system; the power consumption, the gas consumption, the water consumption and the heat consumption of the heating system; power usage of the lighting system; office electricity consumption; residential electricity consumption, gas consumption and water consumption; at least one of electricity consumption, gas consumption and water consumption in the production link.
And S2, dividing buildings with the same or similar environmental parameters into the same group.
Wherein, the condition that the environmental parameters of the buildings are the same means that the environmental parameters of the buildings are completely the same; the similarity of the environmental parameters of the buildings means that the environmental parameters of the buildings fall within a preset range. For example: the geographic locations of the building 001, the building 002 and the building 003 are all within the geographic location range of 38 degrees 39 '-38 degrees 10' north latitude and 104 degrees 04 '-104 degrees 05' east longitude, and the environmental parameters of the geographic locations of the building 001, the building 002 and the building 003 are similar. For another example: the outdoor temperatures of building 001, building 002, and building 003 are all in the temperature range of 25-26 degrees celsius, and the outdoor temperatures of building 001, building 002, and building 003 are considered to be similar.
The purpose of this step grouping is: the buildings which can be subjected to energy consumption comparison are divided into a group, the buildings in the group are considered to have the same energy consumption condition, and therefore the energy consumption comparison of the buildings in the group can reflect the energy consumption condition of the buildings.
S3, building energy consumption standards of a group are determined.
Determining the building energy consumption criteria within a group may be in any one of three ways:
the first method is as follows: and acquiring a pre-stored preset threshold value from a database or a human-computer interaction interface, and taking the preset threshold value as a building energy consumption standard.
The second method comprises the following steps: and acquiring a pre-stored preset threshold value from a database or a human-computer interaction interface, and generating an energy consumption standard based on the preset threshold value and the environmental parameters of the building.
The third method comprises the following steps: an energy consumption standard is generated based on the energy consumption data for the buildings within the group.
The preset threshold may be input by a user or stored in a database, and may be an empirical value or a standard value, which is not limited in the present invention.
The second mode and the third mode can realize that the energy consumption standard of the buildings in the same group is dynamically changed according to the natural environment parameters (such as air temperature) of the buildings. Such as: for buildings in the north, the outdoor temperature in winter is low, the energy consumption for heating is high, and the temperature in winter in the south is higher than that in the north, and the energy consumption for heating is low. In the second and third modes, the temperature sensor transmits the natural environment parameters (such as the annual average air temperature) of the building to the cloud server, and the cloud server calculates the influence of the natural environment on the energy consumption of each building when calculating the energy consumption standard, for example, the energy consumption standard of the building located in a region with a low air temperature is relatively low if other conditions are the same. At this time, the buildings in the same group may be geographically distant but have the same outside annual average air temperature, so that the difference in the energy consumption of the buildings in the group can reflect the difference in the energy consumption of the buildings between two regions (e.g., inner Mongolia and Beijing). The difference between the second mode and the third mode is whether a preset threshold is used, the building energy consumption standard in the third mode completely depends on the energy consumption data of the buildings in the same group in the acquisition stage, and the energy-saving buildings and/or the over-standard buildings in the same group can be found more easily. And the second mode is more referential when determining the standard, so that the situation that all problems cannot be found when a plurality of buildings exceed the standard is avoided.
S4, identifying buildings and/or energy-saving buildings in the group with energy consumption exceeding standard based on the building energy consumption standard of the group.
Wherein the building energy consumption criteria within the group include: the energy consumption standard exceeds the standard and/or the energy-saving standard.
In the step, identifying the buildings with the energy consumption exceeding the standard based on the energy consumption exceeding the standard; and/or identifying energy saving buildings within the group based on energy saving criteria.

It should be noted that the second preset environmental parameter is an environmental parameter different from the first preset environmental parameter. In the present invention, the number of packets and the number of stages are not limited and are determined according to actual conditions. The grouping process may be a semi-automatic process or an automatic process, such as clustering, and the grouping formed last may also produce different results with different buildings to be grouped, and the invention is not limited thereto.
