[0036] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.
[0037] First embodiment
[0038] Please refer to Figure 1 This embodiment provides a method for tracking and measuring individual carbon footprints in a building (hereinafter referred to as the "method"). The method is mainly used to measure and record the carbon emissions caused by individual activities in the building in chronological order. The method includes the following steps:
[0039] S1: Decompose energy consumption and divide the carbon emissions caused by individual activities in the building into independent carbon emissions and shared carbon emissions.
[0040] Individual carbon emissions refer to carbon emissions generated entirely by individual behavior and are unrelated to other people. For example, these emissions are generated during the independent use of personal or public office equipment. Shared carbon emissions refer to carbon emissions generated by more than one person. This type of carbon emission must be shared by each individual who contributes to the carbon emission.
[0041] S2: Measure the independent carbon emissions and shared carbon emissions within the minimum time step.
[0042] The independent carbon emissions measurement method involves attributing the carbon emissions generated by an individual's independent use of personal office equipment and the carbon emissions generated by the independent use of public office equipment over a predetermined time period to the user. Specifically, when an individual uses personal office equipment or public energy equipment, the user's identification system matches the tags on the personal office equipment or public energy equipment, and the energy consumption of the personal office equipment or public energy equipment is attributed to the user.
[0043] The individual carbon emissions within the minimum time step are equal to the product of the individual's occupancy function for the device and the device's power function, integrated over the minimum time step. The occupancy function is a function relative to time t, with its value at time t being 1 when the individual is occupying the device and 0 when the individual is not. The power function is a function relative to time t, with its value at time t being the power of the device at that moment.
[0044] The method for measuring shared carbon emissions involves two steps: energy usage zone division and carbon emission decomposition. Specifically, energy usage zone division divides individual activity areas into the smallest measurement units; carbon emission decomposition maps public energy equipment to the smallest measurement units, breaking down the energy consumption of public energy equipment into each of these smallest measurement units.
[0045] Among them, energy consumption area division refers to dividing an individual's activity area into the smallest metering units, so that an individual's activities in the building can be tracked without duplication or omission. Public energy refers to public energy equipment used by multiple people, including but not limited to lighting, air conditioning, and multimedia equipment. Public energy equipment needs to be mapped one-to-one with energy consumption areas, and the energy consumption of public energy equipment must be broken down into each smallest metering unit. The specific means of measuring shared carbon emissions can be to set labels on public energy equipment; when an individual uses public energy equipment, the user's identification system matches the label on the public energy equipment, and the energy consumption of the public energy equipment is included in the user's smallest metering unit.
[0046] The carbon emissions from a shared area within the minimum time step are equal to the integration of the shared area coefficient for an individual multiplied by the power function for that area over the minimum time step. The shared area coefficient is a function relative to time t, where its value at time t is the value of the occupancy function for that individual divided by the sum of the occupancy function values of all individuals for that public area at that time. The power function is a function relative to time t, where its value at time t is the power of the public area at that time.
[0047] S3: Add individual carbon emissions and shared carbon emissions to obtain the individual’s energy consumption within the minimum time step.
[0048] The beneficial effects of the method for tracking and measuring personal carbon footprint in buildings provided by this embodiment include:
[0049] 1. It can accurately measure each individual's carbon emissions, linking personal behavior with the building's energy consumption and carbon emissions, facilitating lean management of the building's energy consumption and carbon emissions;
[0050] 2. Accurately measure the carbon emissions impact of individual behaviors, facilitating the establishment of individual environmental impact assessment mechanisms as a standard for companies to continuously improve energy sustainability;
[0051] 3. The measurement method directly links individual behavior with carbon emissions, especially situations that lead to excessive carbon emissions, which can give each individual an intuitive feeling and facilitate the development of energy-saving and low-carbon living and working habits.
[0052] Second embodiment
[0053] This embodiment provides a system for tracking and measuring personal carbon footprints within buildings (hereinafter referred to as the "system"), which is primarily used to implement the method provided in the first embodiment. The system includes a tag, an identification system, an energy consumption metering sensor, a personal trajectory tracking sensor, and a carbon emissions mapping device.
[0054] The tags are installed on personal and public office equipment, and the identification system is installed on the user. When the user uses the personal or public office equipment, the identification system matches the tag. When the individual needs to use the personal or public office equipment, the identification system must be matched with the tag to indicate the start of energy use. When the individual ends the personal or public office equipment, the identification system must be matched with the tag again to indicate the end of energy use. During the period between the end time and the start time, the energy consumption of the personal or public office equipment is included in the individual's carbon emissions.
[0055] The energy consumption metering sensor device is used to measure the user's independent carbon emissions and shared carbon emissions within the minimum time step, and add the independent carbon emissions and shared carbon emissions to obtain the individual's energy consumption within the minimum time step.
[0056] Specifically, energy consumption metering sensors are used to measure the energy consumption of energy-consuming equipment at the smallest granularity. This can be achieved through two methods: direct measurement and indirect measurement. Direct measurement involves installing energy consumption metering sensors on power circuits to achieve circuit-level measurement. Indirect measurement, for systems such as central air conditioners that require other media functions, uses energy consumption metering sensors to monitor the status of each energy-consuming node and break down the overall energy consumption of the equipment into its individual energy-consuming areas.
[0057] Personal trajectory tracking sensors are used to track the movement trajectory of an individual in a building and determine the energy consumption area in which the individual is located during each time period. There are two ways to track personal trajectories: absolute position measurement and event-triggered measurement. Absolute position measurement means that an individual can determine their three-dimensional spatial position at any moment. Event-triggered measurement means that an individual only needs to provide an initial state, and the event of entering from one energy consumption area to another triggers the change in energy consumption area. There are two ways to measure the event triggered by the change in energy consumption area: one is to use the tags mentioned above, and the other is absolute position measurement. Absolute position measurement means that an individual can determine their three-dimensional spatial position at any moment, and trigger events by switching the absolute position in each energy consumption area. In this way, the two methods are used in combination to determine the energy consumption area in which the individual is located and whether the energy consumption area has changed based on absolute position measurement.
[0058] The carbon emissions mapping device is used to map the energy consumption of energy-consuming areas or equipment to individual carbon emissions through individual trajectory tracking. This process primarily involves two steps: one is to map the energy consumption of energy-consuming equipment to individuals by matching the equipment's tags with those of individuals. The other is to map energy-consuming areas. The rules are as follows: During each time period, if there is an individual in the energy-consuming area, the energy consumption of that area during that time period is decomposed across all individuals within that area. If there is no individual in the energy-consuming area, the energy consumption of that area during that time period is decomposed across all individuals within that area. If there is no individual in the energy-consuming area, the energy consumption of that area during that time period is decomposed across all individuals within the previous time period where someone was present.
[0059] The beneficial effects of the personal carbon footprint tracking and metering system in buildings provided by this embodiment include:
[0060] 1. It can accurately measure each individual's carbon emissions, linking personal behavior with the building's energy consumption and carbon emissions, facilitating lean management of the building's energy consumption and carbon emissions;
[0061] 2. Accurately measure the carbon emissions impact of individual behaviors, facilitating the establishment of individual environmental impact assessment mechanisms as a standard for companies to continuously improve energy sustainability;
[0062] 3. The measurement method directly links individual behavior with carbon emissions, especially situations that lead to excessive carbon emissions, which can give each individual an intuitive feeling and facilitate the development of energy-saving and low-carbon living and working habits.
[0063] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
