[0044] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0045] In related technologies, the ventilation function of a building is generally determined manually according to the requirements of the building design ventilation code, so as to ensure the ventilation function of the rooms in the building that use natural ventilation. However, manual efficiency is limited, and the efficiency of determining the ventilation function of a building is too low.

[0086] The adjustment parameters of the three-dimensional model are determined based on the total ground area of ​​the building to be reviewed and the ventilation schedule.

[0087] Adjust the 3D model diagram according to the adjustment parameters.

[0088] With the continuous development of the construction industry, issues such as construction quality and the environment are receiving increasing attention. Factors such as lighting, ventilation, and construction quality all affect the quality of life and work for residents. Therefore, to protect residents' rights, relevant authorities issue a series of normative documents for buildings as building standards, and scholars also conduct research to improve the residential functionality of buildings, documenting relevant building standards.

[0089] These building standards can all serve as building design codes, including building ventilation design codes. According to the requirements of building ventilation design codes, it is necessary to determine the ventilation function of a building and ensure the ventilation function of rooms within the building that rely on natural ventilation. This work is generally done manually, but manually determining the building's ventilation function is too inefficient.

[0090] Therefore, the aforementioned deficiencies exist in the methods for determining the ventilation function of relevant buildings. To address these deficiencies, the embodiments of the present invention aim to improve the efficiency of determining the ventilation function of buildings by using a three-dimensional model of the building under review.

[0091] The following explanation, through specific exemplary solutions, clarifies the scope of protection claimed in the claims of this invention, so that those skilled in the art can better understand the scope of protection of the claims. It is understood that the following exemplary solutions do not limit the scope of protection of this invention, but are only used to explain this invention.

[0092] For example, refer to Figure 2 In one embodiment of the method for determining the ventilation function of a building according to the present invention, the method includes the following steps:

[0093] Step S10: Obtain a 3D model of the building to be reviewed;

[0094] In this embodiment, the building to be reviewed is the building whose ventilation function needs to be determined. This building can be either already constructed or yet to be constructed; that is, the building to be reviewed can be a design scheme. The building to be reviewed may include one or more rooms, each composed of architectural elements such as floors, wall panels, ceilings, windows, and doors. These architectural elements are three-dimensional, therefore a three-dimensional model of the building can be drawn. The three-dimensional model of the building to be reviewed is a scaled-down model of the actual constructed building, allowing for a visual determination of its structure. Based on the three-dimensional model, various component parameters of the building can be obtained, such as the height of various locations within the building, the dimensions of each room, the dimensions of windows, and the dimensions of doors. The dimensions can be further refined into parameters such as length, width, height, radius, and arc length based on the shape of each element.

[0095] Step S20: Determine the floor area and effective window area of ​​the target room in the building to be inspected based on the three-dimensional model diagram;

[0096] In this embodiment, the target room in the building to be inspected is first determined in the three-dimensional model diagram. The target room is the room in the building to be inspected that needs natural ventilation. The target room includes at least one window with an effective opening area. The effective opening area refers to the opening area that actually connects the interior and exterior when the window is fully opened.

[0097] It is understandable that the area of ​​a window is not necessarily equal to the effective opening area. For example, in the most common type of sliding glass window, under normal circumstances, when this type of glass window is fully opened, there will be space for at least one pane of glass to accommodate the other panes. This space is not an area that actually connects the interior and exterior. Therefore, the area of ​​the window is not equal to the effective opening area.

[0098] Optionally, the room type of each room in the building to be reviewed is determined based on the three-dimensional model diagram; it is determined whether the room type of each room belongs to the target room type that requires natural ventilation as specified in the ventilation code; if the room type belongs to the target room type, the corresponding room is determined to be the target room.

[0099] A 3D model can be a model annotated with each room type, allowing the identification of each room type. Alternatively, it can be a model depicting furniture, determining the room type based on the furniture information. A 3D model can also be a model of a building type, with the model type determined by the building type under review. The model then determines the wall structure and floor area of ​​each room, and finally, the room type. For example, if the building under review is a residential building, the 3D model type is also residential. Residential buildings typically have one bedroom, one living room, one bathroom, and one kitchen; two bedrooms, one living room, one bathroom, and one kitchen; or three bedrooms, one living room, two bathrooms, and one kitchen. The rooms are generally in similar locations, but the areas of different room types vary. Therefore, the room type of each room in a residential building can be determined based on the wall information and floor area.

[0100] Ventilation standards serve as the criteria for determining the ventilation function of a building under review. These standards specify the detailed parameters for determining this function and also define the target room types for which ventilation function determination is required. The process involves identifying whether a room in the building falls under a target room type as defined in the standards. If a room does, it is designated as a target room. For example, if the standards designate bedrooms, bathrooms, kitchens, and living rooms as target room types requiring ventilation function determination, then bedrooms, bathrooms, kitchens, and living rooms in the building under review are all target rooms. Storage rooms, however, are not considered target rooms and their ventilation functions are not determined. This method of determining ventilation function based on the specific ventilation requirements of different room types improves the efficiency of determining the overall ventilation function of the building under review.

[0101] After identifying all target rooms in the building to be reviewed, the component parameters of the building to be reviewed are determined based on the 3D model. Based on the component parameters, the floor area and effective window opening area of ​​each target room are determined.

[0102] Step S30: Determine the ventilation function of the target room based on the effective window area and the floor area;

[0103] In this embodiment, the effective window area is a necessary gateway for indoor and outdoor communication. For a room, the larger the effective window area, the easier it is for outdoor air to circulate indoors. In addition, the size of the room is also related to the room's ventilation function. With the effective window area remaining constant, the larger the room, the worse the room's ventilation function. The effective window area and floor area of ​​the target room are key factors that determine the ventilation function of the target room. The ventilation function of the target room can be determined according to the preset formula, the effective window area, and the floor area.

[0104] Optionally, the ratio of the effective window area to the floor area is determined; when the ratio is greater than or equal to the preset ratio of the ventilation standard, the ventilation function of the target room is determined to be qualified.

[0105] The ratio P of the effective window area S1 to the floor area S2 is calculated using the following formula:

[0106] P = S1 / S2

[0107] The larger the effective window area, the larger the ratio, and the better the ventilation function of the room. On the contrary, the smaller the ratio, the worse the ventilation function. And the larger the floor area, the smaller the ratio, and the worse the ventilation function of the room. On the contrary, the larger the ratio, the better the ventilation function. It can be concluded that the larger the ratio, the better the ventilation function. The ventilation code is the standard for the building ventilation function. Among them, the preset ratio of the effective window area to the floor area of the room is recorded. For example, the ratio of the effective window area of a living or working room to the floor area of the room should not be less than 1 / 20, and 1 / 20 is the preset ratio. When the ratio determined according to the three-dimensional model diagram is greater than or equal to the preset ratio specified in the ventilation code, it is determined that the ventilation function of the target room is qualified.

[0108] Optionally, determine the preset ventilation parameter of the room type set in the ventilation code; determine the preset ratio of the effective window area to the floor area according to the preset ventilation parameter.

[0109] The room type of the target room belongs to the target room type in the review code. The target room type is the room type that needs to determine the ventilation function specified in the review code. The review code gives different preset ventilation parameters for different room types. For example, the ratio of the effective window area of a living or working room to the floor area of the room should not be less than 1 / 20, and the effective ventilation opening area of the kitchen should not be less than 1 / 10 of the floor area of the room. The preset ventilation parameter can also include other determination criteria in addition to the ratio of the effective window area to the floor area. For example, the effective window area of the kitchen shall not be less than 0.6 m2. First, determine the preset ventilation parameter of the room type of the target room set in the ventilation code, and then determine the preset ratio of the effective window area to the floor area from the preset ventilation norm.

[0110] Step S40: Determine the ventilation function of the to-be-reviewed building according to the ventilation function of the target room in the to-be-reviewed building.

[0111] In this embodiment, after determining the ventilation functions of each target room in the to-be-reviewed building, the ventilation function of the to-be-reviewed building is determined according to the ventilation functions of the target rooms of the to-be-reviewed building. When the ventilation functions of the target rooms that need natural ventilation in the to-be-reviewed building are all qualified, the ventilation function of the to-be-reviewed building is also qualified.

[0112] Optionally, generate a ventilation detail list according to the ventilation function, the floor area, and the effective window area of each target room; determine the ventilation function of the to-be-reviewed building according to the ventilation detail list.

[0113] Refer to Figure 4, the ventilation list includes each target room, whether ventilation is adopted in the room, as well as the floor area and effective window opening area of the target room. Among them, if the ventilation function meets the ventilation code, the ventilation function is qualified. According to the ventilation list, the ventilation function of the building to be reviewed can be seen intuitively, and it is also more convenient to calculate the ventilation function of the building to be reviewed.

[0114] Optionally, when the ventilation function of each target room on the ventilation list is qualified, it is determined that the ventilation function of the building to be reviewed is qualified; when the ventilation function of each target room on the ventilation list is unqualified, it is determined that the ventilation function of the building to be reviewed is unqualified; the adjustment parameters of the 3D model diagram are determined according to the total floor area of the building to be reviewed and the ventilation list; the 3D model diagram is adjusted according to the adjustment parameters.

[0115] There are relevant component parameters on the review list, as well as the ventilation function of the target room. According to the review list, the ventilation function of each target room can be determined. When each target room meets the requirements of the ventilation code, the ventilation function of the target room is qualified, and the ventilation function of the building to be reviewed meets the requirements of the ventilation code, and the ventilation function of the building to be reviewed is qualified. When there is a target room that does not meet the requirements of the ventilation code, the ventilation function of the target room is unqualified, and the ventilation function of the building to be reviewed does not meet the requirements of the ventilation code, and the ventilation function of the building to be reviewed is unqualified.

[0116] When the ventilation function of the building to be reviewed is unqualified, the 3D model diagram is adjusted according to the total floor area of the building to be reviewed and the ventilation list. When adjusting a target room with an unqualified ventilation function, the effective window opening area can be increased or the floor area can be reduced.

[0117] The review list can also include the ratio of the effective window opening area to the preset floor area of the target room, as well as the corresponding preset ratio. The preset ventilation parameters can be determined according to the ventilation code. The preset ventilation parameters include the preset ratio of the effective window opening area to the preset floor area. Such a ventilation list is generated according to the ventilation function, floor area, effective window opening area, ratio of effective window opening area to floor area, and preset ratio of each target room. When improving the ventilation function of the target room by reducing the floor area, the total floor area of the building to be reviewed remains unchanged. The adjacent rooms to the target room are obtained, and the ventilation situation of the adjacent rooms is determined according to the review list, that is, whether natural ventilation is required. If the adjacent room requires natural ventilation, the ratio of the effective window opening area to the floor area of the adjacent room is determined. If the ratio is large enough, greater than the preset maximum ratio, the floor area of the target room is expanded, and the floor area of the adjacent room is correspondingly reduced; if the ratio is not greater than the preset maximum ratio, the ratios of the effective window opening areas to the floor areas of other rooms are traversed.

[0118] In the technical solution disclosed in this embodiment, a three-dimensional model of the building to be reviewed is first obtained; the floor area and effective window opening area of ​​the target room in the building to be reviewed are determined based on the three-dimensional model; the ventilation function of the target room is determined based on the effective window opening area and the floor area; and the ventilation function of the building to be reviewed is determined based on the ventilation function of the target room. In this way, the target room in the building, as well as the floor area and effective window opening area of ​​the target room, can be determined using the three-dimensional model of the building to be reviewed. The effective window opening area is a factor in air entering the room. By using the effective window opening area and the floor area, the ventilation function of the target room can be determined, and thus the ventilation function of the building to be reviewed can be determined. Compared with manually determining the ventilation function of the building to be reviewed, this method can improve the efficiency of determining the building's ventilation function.

[0119] Optionally, refer to Figure 3 Based on any of the above embodiments, in another embodiment of the method for determining the building ventilation function of the present invention, the method for determining the building ventilation function further includes:

[0120] Step S50: Determine the room dimensions of the target room and the effective window opening dimensions of the windows based on the three-dimensional model diagram;

[0121] In this embodiment, the component parameters of the building to be inspected can be determined based on the three-dimensional model. The component parameters include the room dimensions and the effective window opening dimensions.

[0122] Step S60: Determine the theoretical ventilation area in the room based on the effective window opening size;

[0123] In this embodiment, the effective window opening size is the maximum opening size that the window can be opened. In a rectangular window, the effective window opening size includes the effective window length and the effective window width. Assuming that a standard level of wind blows outside the window, the area that can theoretically feel the wind blowing in through the effective window on the inside of the window can be determined based on the effective window opening size, which is the theoretical ventilation area.

[0124] Step S70: Determine the actual ventilation area based on the theoretical ventilation area and the room dimensions.

[0125] In this embodiment, the height of the theoretical ventilation area may exceed the height of the target room, the width may exceed the width of the target room, or the length may exceed the length of the target room. The actual ventilation area needs to be determined based on the actual room size of the target room.

[0126] Optionally, the size of the target room is determined based on the room dimensions; the ventilation function of the target room is determined based on the ratio of the effective window area to the floor area and the ratio of the actual ventilation area to the size of the space.

[0127] Room dimensions include the length, width, and height of the room. Based on these dimensions, the size of the target room can be calculated. The ratio of the actual ventilation area to the room size can more directly determine the impact of indoor and outdoor airflow on the entire target room. Thus, in addition to determining the ventilation function of the target room based on the ratio of the effective window area to the floor area, the ratio of the actual ventilation area to the room size can also be used to determine the ventilation function of the target room, which can improve the accuracy of determining the ventilation function of the target room.

[0128] In the technical solution disclosed in this embodiment, the room dimensions of the target room and the effective window opening dimensions are determined based on the three-dimensional model diagram; the theoretical ventilation area within the room is determined based on the effective window opening dimensions; and the actual ventilation area is determined based on the theoretical ventilation area and the room dimensions. By determining the actual ventilation area using the room dimensions and the effective window opening dimensions, the ventilation situation of the target room can be directly determined, thus more accurately determining the ventilation function of the target room.

[0129] Furthermore, this invention also proposes a device for determining the ventilation function of a building. The device includes a memory, a processor, and a program for determining the ventilation function of a building stored in the memory and executable on the processor. When the program for determining the ventilation function of a building is executed by the processor, it implements the steps of the method for determining the ventilation function of a building as described in the above embodiments.

[0130] Furthermore, embodiments of the present invention also propose a computer-readable storage medium storing a program for determining the ventilation function of a building. When the program for determining the ventilation function of a building is executed by a processor, it implements the steps of the method for determining the ventilation function of a building as described in the above embodiments.
