[0052] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0053] Example 1:
[0054] like Figure 1 As shown, this embodiment provides a building shading adaptive dynamic control method, including the following steps:
[0055] S10, establishing a building simulation model;
[0056] like Figure 2 As shown, in this embodiment, the room parameters include architectural characteristic parameters and building thermal parameters. Architectural characteristic parameters include space dimensions and environmental occlusion, while building thermal parameters include boundary conditions, internal heat sources, and HVAC parameters. A full-scale room model was constructed using a typical office room in Guangzhou as an example. The room measures 6m wide, 4m deep, and 4m high and is located on the central floor of an office building. The room has only one exterior wall connected to the outdoors, with a centrally located window. The room's thermal parameters were set according to the General Specification for Energy Conservation and Renewable Energy Utilization in Buildings (GB55015-2021).
[0057] In this example, to better demonstrate the control model's optimization of lighting energy consumption, a stepless dimming system was used to ensure optimal lighting quality (work surface illuminance > 500 lux). When natural light is sufficient, the lighting system is turned off to conserve energy. The lighting points were set 1m and 3m from the window, and 0.75m high.
[0058] In this embodiment, the sunshade device is a roller blind sunshade device arranged outside the outer window, and its size is consistent with that of the outer window.
[0059] S20, such as Figure 3 As shown, according to the usage scenario and environmental parameters, the building performance simulation model is used to set different shading state conditions, calculate the building performance simulation results, and optimize the building performance simulation results according to the optimization goal to obtain the optimal shading state schedule throughout the year; the following steps are included:
[0060] S21. Set optimization goals;
[0061] In this embodiment, the optimization goal is set as: while satisfying the glare index DGI at 1 m away from the window < 25, the shading state operating condition parameter group with lower building energy consumption is the more optimal value.
[0062] S22. Input usage scenario and environmental parameter group;
[0063] In this embodiment, the usage scenarios include HVAC set temperature and occupancy schedule;
[0064] In this embodiment, the environmental parameter group is the meteorological data of a typical meteorological year, which is a collection of multiple environmental meteorological data with a period of one year and a time interval of one hour. Specifically, it is the China Standard Weather Data (CSWD) of Guangzhou. The meteorological data has a period of one year and a time interval of one hour, including outdoor temperature and humidity, solar radiation intensity, and work surface illumination.
[0065] S23. For each piece of environmental meteorological data, set different shading state conditions, and simulate and calculate the building performance simulation results corresponding to the shading state condition parameter group;
[0066] In this embodiment, the sunshade device is a roller blind sunshade device. Therefore, according to the control method of the sunshade device, the working parameter of the sunshade device is set as the lowering height, and the lowering height is divided into five levels at equal intervals to obtain a sunshade state working condition parameter group [0%, 25%, 50%, 75%, 100%]; among them, 0% and 100% represent unobstructed and completely obstructed working conditions, respectively.
[0067] In another embodiment of the present invention, the sunshade device is a blind, and the working parameter of the sunshade device is set to be a blind angle. The blind angle is divided into four levels at equal intervals to obtain a sunshade state working condition parameter group [0, 30, 60, 90];
[0068] S24. According to the set optimization goal, select the shading state working condition parameter corresponding to the optimal building performance simulation result in the environmental meteorological data, and record it as the optimization result corresponding to the environmental meteorological data;
[0069] In this embodiment, all shading conditions are simulated according to the environmental parameter group input in step S22, and the shading state with DGI less than 25 and minimum energy consumption in each hour is recorded as the optimization result corresponding to that hour.
[0070] S25. Traverse and calculate the optimization results of all environmental meteorological data in the environmental parameter group to obtain the optimal shading state schedule for the whole year.
[0071] In this embodiment, the China Standard Weather Data (CSWD) for Guangzhou has a total of 8760 hours of meteorological data, so steps S23-S24 are iterated 8760 times so that all environmental meteorological data have corresponding optimization results, and the optimization results are combined into an optimal sunshade status schedule for the entire year.
[0072] S30, such as Figure 4 As shown, a building shading adaptive control model is established, and the building shading adaptive control model is trained using the optimal shading state schedule throughout the year, including the following steps:
[0073] S31. Select a machine learning classification algorithm to establish a building shading adaptive control model;
[0074] In this embodiment, the random forest algorithm (RF) and the decision tree algorithm (DT) are respectively selected to establish the building shading adaptive control model, and the use of the two algorithms is based on the Sk-learn library of Python.
[0075] S32, converting the optimal shading state working condition parameters into classification labels and setting them as the output of the model, setting the environmental meteorological data and usage scenarios as the feature inputs of the model, and using the optimal shading state full-year schedule obtained in step S25 to train the building shading adaptive control model;
[0076] The feature inputs of the random forest algorithm (RF) and decision tree algorithm (DT) are as follows Figure 5 As shown;
[0077] Among them, the environmental parameters in the feature input of the random forest algorithm (RF) include: incident solar radiation intensity on the building facade (Incident solar radiation on the facade), outdoor air temperature (Outdoor temperature), set-point temperature for indoor air conditioning and cooling (Set-point temperature for cooling), daylight illuminance on the first working surface (Daylight illuminance 1), and daylight illuminance on the third working surface (Daylight illuminance 3);
[0078] The environmental parameters in the feature input of the decision tree algorithm (DT) include: incident solar radiation intensity on the building facade (Incident solar radiation on the facade), outdoor air temperature (Outdoor temperature), set-point temperature for indoor air conditioning and cooling (Set-point temperature for cooling), and daylight illuminance 2 on the second working surface (Daylight illuminance 2).
[0079] The collection points for the daylighting illuminance of the first, second, and third working surfaces are set based on their distance from the exterior windows, and are all collected using daylighting sensors. The number of daylighting sensors used by the random forest algorithm (RF) and the decision tree algorithm (DT) differs. RF uses two daylighting sensors to collect the daylighting illuminance of the first and third working surfaces, enabling more precise adjustment of the indoor lighting environment by controlling the external shading state. The decision tree algorithm (DT) uses data from a single daylighting sensor, reducing the number of sensors while still achieving similar energy savings.
[0080] It should be noted that the number and orientation of the lighting illumination data collection points in the adaptive control model established for different scenarios (for example, the orientation of the lighting illumination sensor, which defaults to horizontal illumination, but in some cases is vertical illumination) are selected and adjusted according to actual needs.
[0081] S33, adjusting and pruning the building sun shading adaptive control model to obtain a trained building sun shading adaptive control model.
[0082] In this embodiment, the prediction accuracy of the building shading adaptive control model based on the random forest algorithm (RF) and the decision tree algorithm (DT) in each direction is as follows: Figure 6 As shown in the figure, it can be seen that both building shading adaptive control models can achieve good prediction accuracy in the simulation data.
[0083] Figure 7 This is a visualized optimal roller blind lowering position decision tree diagram of the building sunshade adaptive control model established based on the decision tree algorithm (DT) of this embodiment. It can be seen that the building sunshade adaptive control model established using the method of this embodiment has good interpretability.
[0084] S40. Use sensors to dynamically collect environmental data (i.e., environmental parameters), and use a building shading adaptive control model to obtain optimal shading state conditions based on the environmental data, thereby achieving building shading adaptive dynamic control.
[0085] S50: Using a memory to record environmental data collected by sensors and user usage habits, and updating an optimal shading state annual schedule and a building shading adaptive control model based on the environmental data and user usage habits stored in the memory.
[0086] Figure 8 and Figure 9 The following are comparison graphs of the annual energy consumption performance of the building shading adaptive dynamic control method of this embodiment and other methods in west-facing rooms and south-facing rooms. It can be seen that the results for the south and west directions are not much different and show the same trend. Secondly, it can be clearly observed that the lighting energy consumption and cooling energy consumption under the Ctrl-RF and Ctrl-DT shading control obtained by this method are almost the same as the optimization results. Compared with Ctrl-Solar, Ctrl-DGI and Ctrl-Work, a lower comprehensive energy consumption level can be achieved. This shows that although there is a certain error in the prediction of the hourly shading position through the adaptive control model, its energy-saving effect is almost the same as that of the optimal shading control, and it is more energy-efficient than the general shading strategy.
[0087] Figure 10 and Figure 11 The adaptive dynamic control method for building shading of this embodiment is compared with the annual UDI (100-2000 lux) ratio under different shading control strategies in south-facing rooms and west-facing rooms. In south-facing rooms, the adaptive shading control models (Ctrl-RF and CRTL-DT) proposed by this method are basically the same as the optimization results, with a ratio of more than 70%. Compared with the benchmark room (without shading), the adaptive shading control (Ctrl-RF and CRTL-DT) proposed by this method can reduce the proportion of time >2000 lux, increase the proportion of UDI (100-2000 lux), avoid uncomfortable glare and reduce lighting needs.
[0088] In summary, this embodiment greatly improves the effect of dynamic shading equipment in energy saving and adjusting indoor light environment by combining simulation optimization with machine learning, realizes flexible and scientific response to environmental parameters collected by sensors, and can adapt to changes in indoor and outdoor environments and changes in user usage habits. Compared with traditional shading control methods based on a fixed value, the method of the present invention is more targeted in control objectives and can be closer to achieving the optimization objectives set by users; this embodiment realizes automatic and continuous shading state optimization by setting up a memory, combining building performance simulation with computer programming, reducing the time and energy invested in human control, and realizing a cyclic process of input → simulation → reading results → optimization → re-input according to the results after optimization. By continuously collecting new data for simulation optimization and model training, the accuracy of prediction and versatility in different usage scenarios are improved. In addition, through this method and process, users do not need to have professional knowledge related to architectural science and computer science, and can obtain a nearly optimal shading adaptive control strategy by following the prompts. This embodiment uses machine learning to establish a shading adaptive control model and converts the output of the shading adaptive control model into classification labels, thereby improving the prediction efficiency of the model, so that the shading adaptive control model can achieve good classification effects even when the number of samples is small, and at the same time will not impose too much burden on the performance of the controller.
