DESCRIPTION Technical Field The embodiments disclosed herein relate to an automated method for generating a modified visualization. A corresponding computer program product and a corresponding autonomous system for executing such method are disclosed as well. Background Buildings contribute to 18 to 20% of the global greenhouse gas emissions. It is important to address this in the overall journey of decarbonization and sustainable development. Simulations, digital twins and industrial metaverse together are helping different industries to excel at the different stages of the life cycle. Accordingly, there is a need for supporting the overall journey of decarbonization and sustainable development of buildings. Summary 202321252 Embodiments herein generally relate to a method for generating a modified visualization, the modified visualization visualizing the environment comprising the modified object and visualizing the variation parameter. The method comprising the following steps. A step of the method is generating an initial visualization, especially based on a simulation model. The initial visualization visualizes an environment comprising an initial object (= initial component). A construction, e.g. a set-up and / or a structure and / or a construct, and / or a architecture, of the initial object is defined (=described / characterised) by structural parameters. A further step of the method is receiving a user input comprising a modification parameter, the modification parameter defining a modification (= change) in at least one of the structural parameters (resulting in a modification of the construction of the initial object, again resulting in a modified object), wherein the user input being received by gathering a user movement in relation to the initial visualization. E.g. the user input is received “within” the initial visualization while the initial visualization being a 3d visualization; “in relation” means that the visualization is shown to the user in a place (= location) in the real world, the user movement (also a user “interaction” with the visualization) is performed in relation to the place (= location) the initial visualization is visible to the user. The user motion is especially a hand gesture, an arm gesture and / or a body movement. A further step of the method is determining (= calculating) a modified object (= modified component) using the modification parameter and at least part of the structural parameters. The modified object is a modification of the initial object. The modified object is equal to the initial object regarding the for the determination used part of the structural parameters (the structural parameters, which also define the 202321252 construction of the initial object. The modified object is different (e.g. modified) to the initial object regarding the for the determination used modification parameter. A further step, especially performed by using a physics-based digital twin, of the method is calculating a variation parameter, the variation parameter describing a difference (= change) in a physical impact (= output, effect) between a physical realisation of an environment comprising the modified object and a physical realisation of the environment comprising the initial object, (e.g. predicted influence of the modification parameter on the initial object and on the environment, e.g. a predicted change in the physical impact (=output, effect) of the environment comprising the modified object compared to the environment comprising the initial object). A further step of the method is generating a modified visualization, the modified visualization visualizing the environment comprising the modified object and visualizing the variation parameter. The modified visualization is equal to the initial visualization expect to the modified object and visualizing the variation parameter. The method is especially useful for generating real-time simulations in the industrial metaverse and interactive visualization. The claimed method provides a basis for a framework with methodology and intuitive environment to provide real-time interactive feedback for the user in terms of physical impact parameters, for example energy consumption or carbon footprint, on the change in the structural parameters (input) to take informed decisions at all the stages of the building life cycle, e.g. during layout planning, during operation and / or during maintenance. “Real- time” according to this disclosure is to be understood as “close to real-time”. After the user input is received, the further steps follow immediately. 202321252 “Structural parameters”, also “inputs to the environment”, here refers especially to the layout of the environment (e.g. location of the tables, chairs, people etc.), upgrade decisions (size of the windows, size of the walls, materials used for the walls, location of the meeting room, location of the data centre, location of the different heat sources etc). “Physical impact”, also “physical output of the environment” or “physical effects”, here refers to outputs of the environment, especially refers to the energy consumption, ecological footprint, carbon footprint and / or thermal comfort in the building. In an embodiment the method is performed on multiple user devices, wherein the initial visualization is generated on multiple user devices, wherein multiple user inputs are received from multiple user input sources, e.g. different user inputs are received, wherein multiple versions of one modified object and / or different modified objects are determined, wherein variation parameter are determined for the multiple modified objects, and wherein multiple modified objects are visualizing by the modified visualization. In this embodiment, the method provides an automated end-to-end pipeline which enables interactivity between the users. This has the advantage to provide an immersive, a collaborative and an interactive method to work on the construction of objects in an environment and to get information on the physical impact of the corresponding physical realisations while users are located at different geographical location. A further benefit is that inputs from users with different expertise, e.g. expertise in thermal management, construction, renovation, decarbonisation, etc. can be included. In an embodiment multiple user inputs are received from one user input source (device). This allows one user to test different scenarios before realizing a modification in the real world. 202321252 The method has the further advantage that a virtual test environment is provided, which enables to run multiple scenarios to respect regulations from ISO, GRIHA, ASHRAE 55, CEN. The method further enables the user(s) to understand the change in physical output (e.g. the change in physical effect and / or in physical impact) even if the user(s) is / are not an expert in the field. Thereby the method serves the user to take informed decisions respecting multiple requirements.

Brief Description of the Drawings Fig. 1 shows the steps of a method for generating a modified visualization, and Fig. 2 shows additional steps of the method described in Fig. 1 for realizing a modification in a construction. Detailed Description Fig. 1 shows an automated method comprising the steps: - Step S1: Generating an initial visualization (V1), the initial visualization V1 visualizing an environment comprising an initial object 11, 121, 122, 13, 14, 15, a construction of the initial object 11, 121, 122, 13, 14, 15 being defined by structural parameters 1, - Step S2: Receiving a user input 6 comprising a modification parameter 2, the modification parameter 2 defining a modification in at least one of the structural parameters 1, wherein the user input being received S2 by gathering a user movement S2 in relation to the initial visualization V1, - Step S3: Determining a modified object 51, 521, 522, 53, 54, 55 using the modification parameter 2 and at least part of the structural parameters 1, - Step S4: Calculating a variation parameter 4, the variation parameter 4 describing a difference in a physical impact 16, 56 between: 202321252 o a physical realisation R5 of an environment comprising the modified object 51, 521, 522, 53, 54, 55 and o a physical realisation R1 of the environment comprising the initial object 11, 121, 122, 13, 14, 15, - Step S5: Generating a modified visualization V5, the modified visualization V5 visualizing the environment comprising the modified object 51, 521, 522, 53, 54, 55 and visualizing the variation parameter 4. The method is especially useful for real-time simulation in the industrial metaverse and interactive visualization. In a further embodiment the initial visualization V1 and / or the modified visualisation V5 is arranged (= configured) as a metaverse environment, and / or a three-dimensional environment, and / or an augmented reality environment, and / or a virtual reality environment. The three-dimensional (3D) environment has the advantage that the user movement S2 is gatherable in 3D relation to the place (= location) the initial visualization V1 is visible to the user 6. The metaverse environment, the augmented reality environment and the virtual reality environment are forms of the three- dimensional environment, which enable the user 6 to experience an environment virtually. The augmented reality environment allows the user to see a real-world environment supplemented by annotations, augmentations and / or visual elements shown in relation to the real world. In a further embodiment the environment (comprising the initial object 11, 121, 122, 13, 14, 15 or the modified object 51, 521, 522, 53, 54, 55) is arranged (= configured) as a room, and / or a building, and / or a building 202321252 infrastructure, and / or an urban infrastructure, and / or a village or a city, and / or a park, and / or an industrial environment. Wherein the initial object 11, 121, 122, 13, 14, 15 and the modified object 51, 521, 522, 53, 54, 55 are arranged (= configured) as table, and / or chair, and / or window, and / or wall, and / or room, and / or data centre, and / or heat source, and / or air conditioning, and / or evaporator, and / or duct, and / or cooler, etc. In a further embodiment the method comprises the additional step S2a (not shown in the figures): Sending a demand for the user input comprising the modification parameter 2. The demand asks the user 6 to provide the modification parameter 2. This has the advantage that the availability of the modification parameter 2 is ensured, e.g. in case the user 6 could forget to provide it (regularly). In a further embodiment the step of sending S2a the demand is initiated in periodical time frequency, a defined stage of a life cycle of the environment, a defined stage of a life cycle of the initial object 11, 121, 122, 13, 14, 15. This has the advantage that the demand and the requested user input is initiated / provided in definable time steps. An example for a defined stage of a life cycle is a planned maintenance activity. In a further embodiment the step of receiving S2 the user input initiates the steps of determining S3 the modified object 51, 521, 522, 53, 54, 55 and calculating S4 the variation parameter and generating S5 the modified visualization V5 in (near) real-time. “Real-time” according to this disclosure is to be understood as “close to real- time”. After the user input is received, the further steps, especially the determining S3 the modified object 51, 521, 522, 53, 54, 55 and calculating S4 the variation parameter 202321252 and generating S5 the modified visualization V5 follow immediately. This has the advantage that after the user input is received S2, a collaborative method and / or a virtual test environment to work on the construction of objects in an environment and to get information on the physical impact 16, 56 of the corresponding physical realisations R1, R5 of the objects and the environment are provided in real-time. A simulation and visualization, which are running on a single platform reduces the delay in feedback and thus makes the response V5 real-time and interactive. In a further embodiment the structural parameters 1 and the modification parameter 2 comprise a construction material, and / or a dimension (=size), and / or a geometry, and / or an architectural parameter, and / or a position (=location) within the environment, and / or a machine or device type, and / or a set-up of the said machine or device of the initial object 11, 121, 122, 13, 14, 15 and the modified object 51, 521, 522, 53, 54, 55 (including a feature of the initial object 11, 121, 122, 13, 14, 15 and the modified object 51, 521, 522, 53, 54, 55). The construction of the initial object 11, 121, 122, 13, 14, 15 being defined (=described / characterised) by structural parameters 1. The modification parameter 2 defining a modification (= change) in at least one of the structural parameters 1, resulting in a modification of the construction of the initial object 11, 121, 122, 13, 14, 15, again resulting in a modified object 51, 521, 522, 53, 54, 55. The structural parameters 1 and the modification parameter 2 influence the physical impact 16, 56 (= output 16, 56, effect 16, 56) of the physical realisation R5 of the environment comprising the modified object 51, 521, 522, 53, 54, 55 and 202321252 of the physical realisation R1 of the environment comprising the initial object 11, 121, 122, 13, 14, 15. In a further embodiment for calculating S4 the variation parameter 4 at least part of the structural parameters 1, the modification parameter 2 and an environment structural parameters are used. The variation parameter 4 describing a difference (= change) in a physical impact 16, 56 (= output, effect 16, 56) between a physical realisation R5 of an environment comprising the modified object 51, 521, 522, 53, 54, 55 and a physical realisation R1 of the environment comprising the initial object 11, 121, 122, 13, 14, 15. This means that the variation parameter 4 describes a predicted influence of the modification parameter 2 on the initial object 11, 121, 122, 13, 14, 15 and on the environment, e.g. a predicted change in the physical impact 16, 56 (= output 16, 56, effect 16, 56) of the environment comprising the modified object 51, 521, 522, 53, 54, 55 compared to the environment comprising the initial object 11, 121, 122, 13, 14, 15. Therefore, at least part of the structural parameters 1 and the modification parameter 2 are used to calculate the variation parameter 4. The environment structural parameter can comprise a further factor or further factors defining the construction of the environment, e.g. a construction material used within environment, and / or a dimension (=size) of the environment, and / or a geometry of the environment, and / or an architectural parameter of the environment, and / or at least on structural parameter of at least on further object within the environment. In a further embodiment an output of step S4 are the physical impacts. The input of step S4 is the modification parameter, e.g. the new structural parameter. 202321252 In a further embodiment the step S4 of calculating the variation parameter 4 is done using a simulation, and / or a physics-based simulation, and / or a model, and / or a digital twin, and / or a physics-based digital twin, and / or computer- aided-design model of the physical realisation R1 of the environment comprising the initial object 11, 121, 122, 13, 14, 15 and the physical realisation R5 of the environment comprising the modified object 51, 521, 522, 53, 54, 55. This has the advantage of features to automatically read the structural parameters 1, e.g. material, dimension, and other required simulation inputs from the BIM (Building information modeling) interface / database and the further advantage to update a physics-based simulation model. Tools like energy plus, Amesim, Modelica etc. can be used to model an environment, e.g. a building and to understand the energy consumption 16, 56. Existing standard models and master simulation or DT model can be reused and / or finetuned or 1D simulation models could be automatically generated based on the drawings and the necessary information in the BIM interface. Another feature is capabilities to perform co-simulation when required to get the detailed understandings on the system of interest. For example, Amesim simulation with Star CCM simulation. Co-simulation is the joint simulation of loosely coupled stand-alone sub-simulators. A co-simulation algorithm takes care of time synchronization and interactions across the sub-simulators. The interactions between these sub- simulators are only synchronized at discrete communication points. A virtual test environment also facilitates comparing as built and as planned (designed) structures. This comparison leads to difference between what was designed and what was built. For this the framework has features to represent scanned data (geometry) of the environment or building 202321252 together with a sensor data (physical measurements) overlay. The scanned data and the sensor data lead to the as built structure. The framework also has a calibration feature using real-time sensor measurements to provide close to reality response and adjustments for the virtual test environment, to keep the virtual model in sync with the real system. Therefore, the framework has the feature to seamlessly interact between the sensor data, simulation data and the visualization environment. As framework could host a surrogate model (replacement model). If detailed simulation models are time consuming surrogate models or data driven light weight models can be used. As framework could also host composable modelling (different models which are composed together) and simulation artifacts. In a further embodiment the method comprises the additional step of measuring S1a (not shown in the figures) and / or loading S1a at least part of the structural parameters 1 before generating S1 the initial visualization V1. This additional step might support generating the initial visualization V1. The initial visualization V1 can be either generated from scratch if the structural parameters 1 are measured from a real-world environment R1. As an alternative or supplementary the structural parameters 1 can be loaded, e.g. from a database. Fig. 2 shows additional steps of the method described in Fig. 1. The additional steps are: - Step S6: Receiving a user 6 input which accepts the variation parameter 4 (the user 6 input being gathered in relation to the modified visualization V5, especially in relation to the variation parameter 4 and / or the modified object 51, 521, 522, 53, 54, 55 within the modified visualization V5), 202321252 - Step S7: Receiving a modification command 7, the modification command 7 being a command to realize the modification in the construction of the initial object 11, 121, 122, 13, 14, 15 according to the modification parameter 2 (e.g. to construct the modified object 51, 521, 522, 53, 54, 55), - Step S8: Sending (= providing) the modification command 7 to an execution unit 8, the execution unit 8 being arranged for realizing the modification in the construction of the initial object 11, 121, 122, 13, 14, 15 (e.g. to construct the modified object 51, 521, 522, 53, 54, 55) upon receiving the modification command 7. In general, the purposed method enables a test environment and supports a user 6 with a visualisation of a predicted influence 4 of the modification parameter 4 on the initial object 11, 121, 122, 13, 14, 15 and on the environment, e.g. a predicted change 4 in the physical impact 16, 56 (= output, effect 16, 56) of the environment comprising the modified object 51, 521, 522, 53, 54, 55 compared to the environment comprising the initial object 11, 121, 122, 13, 14, 15. The previous embodiment further enables the realisation R5 of the modification of the (initial) object into the modified object 51, 521, 522, 53, 54, 55 in the real world. Before the user 6 input, which accepts the variation parameter 2 is received S6, a UI to play around with scenarios, e.g. different modified objects 51, 521, 522, 53, 54, 55 can be provided to the user 6. After testing different scenarios, the user 6 selects a preferred scenario, and the modification command 7 is received S7 from the user 6. This embodiment has the advantage that an outcome (variation parameter 4 and corresponding modification parameter 2) of one or od multiple virtual tests is connected to real controllers 8 (execution unit 8) to maintain the sustainable operation of the building infrastructure. 202321252 In a further embodiment the modification command 7 is received S7 from multiple user 6 input sources, wherein the modification command 7 is checked for conformity before it is sent S8 (provided S8) to the execution unit 8. In an embodiment the method is performed on multiple user 6 devices, (e.g. wherein the initial visualization V1 is generated on multiple user 6 devices, wherein multiple user 6 inputs are received S2 from multiple user 6 input sources, e.g. different user 6 inputs are received S2, wherein multiple versions of one modified object 51, 521, 522, 53, 54, 55 and / or different modified objects 51, 521, 522, 53, 54, 55 are determined S3, wherein variation parameter 4 are determined S4 for the multiple modified objects 51, 521, 522, 53, 54, 55, and wherein multiple modified objects 51, 521, 522, 53, 54, 55 are visualizing S5 by the modified visualization V5) wherein the modification command 7 is received S7 from multiple user input 6 sources. This has the advantage to provide a collaborative method to work on the construction of objects in an environment and to get information on the physical impact 16, 56 of the corresponding physical realisations R1, R5 while users 6 are located at different geographical location. Before a modification is realised in the real-world the modification command 7 from multiple user 6 input sources (e.g. from different users 6) is checked for conformity. In a further embodiment the physical impact 16, 56 (referred to by the variation parameter 4) comprising an energy consumption, and / or a carbon footprint, and / or a level of thermal comfort, and / or a level of thermal distribution, and / or a temperature, and / or a water consumption, and / or a heating medium consumption. “Physical impact” 16, 56, also “physical output of the environment” 16, 56 or “physical effects” 16, 56, here refers to outputs 16, 56 of the environment, especially refers to 202321252 the energy or carbon footprint or thermal comfort or time to construct. The structural parameters 1 and the modification parameter 2 influence the physical impact 16, 56 (= output, effect 16, 56) of the physical realisation R5 of the environment comprising the modified object 51, 521, 522, 53, 54, 55 and of the physical realisation R1 of the environment comprising the initial object 11, 121, 122, 13, 14, 15. The structural parameters 1 and the modification parameter 2 of a wall (or a window) define a conduction, a convection, and a radiation of the wall (or of the window). This again defines the physical impact 16, 56 of the physical realisation R1, R5 of the wall (or the window) in the environment. In a further embodiment the variation parameter 2 is visualized by the modified visualization V5 as an augmentation, and / or a further layer, and / or a text box, and / or a sign. The augmented reality environment visualization allows the user 6 to see a real-world environment supplemented by annotations, augmentations and / or visual elements shown in relation to the real world. The embodiments of the visualization of the variation parameter are providing options for a visualization in an augmented reality environment visualization.
