Description

[0001] Description Method and svstem forthe construction of buildinas The invention relates to a method and System forthe construction ofbuildings. In a world where the urgent call fordecarbonization clashes with the pressing need for affordable housing, a profound paradox emerges within the environment. This paradox, coined äs the Housing and Climate Paradox, encapsulates the intricate interplay between the escalating climate crisisand the enduring housing crisis,presenting a formidable challenge tothe pursuitof sustainable development. At the heart of this paradox lies a simple reality: despite global commitments and ambitious targets, the decarbonization and sustainabilitytransition of our builtenvironment remain alarmingly offcourse. Building operational emissions soar to unprecedented levels, contributing significantly to the daunting statistic that buildings are accountable for a staggering 39% of carbon emissions. With current trajectories veering farfrom the2050 net-zero goals, the imperative to curb both embodied and operational carbon emissions looms ever larger. Yet, the pathway to net-zero construction isfraught with obstacles, chiefamong them being the inherent tension between environmental stewardship and housing affordability. The adoption of cost-effective modern methods of construction (MMC) emerges äs a criticallinchpininthisdelicate balancing act. However, the prevailing narrative suggests that pursuing net-zero targets without viable MMC solutions risks exacerbating the housing crisis, äs construction costs escalate, inevitably driving up average housing prices. Enter the "Eco-Economic Theory", a paradigm that illuminates the intricate nexus between theclimate crisisand the housing crisis,underscoring the urgent need for a paradigm shift inconstruction practices. Central to this paradigm the imperative fora low-cost, scalable, net-zero MMC solution one that not only addresses the embodied energy ofour builtenvironment but also mitigates the exacerbating factors ofthe housing crisis. Against this backdrop, becomes evident that the challenges confronting the housing crisisextend farbeyond mere supply-demand dynamics. The dearth of new homes bullt per capita, coupled with shortages in skilled labour, and the industry's high carbon emissions underscore the multifaceted nature of the crisis.Moreover, antiquated construction methods, evolving planning laws, and regulatory frameworks further compound these challenges, necessitating a comprehensive reimaginingofthe construction landscape. In light of these complexities, the imperative for innovation in construction practices has never been more pressing. Thus, isan object of the present invention to provide a holistic method and System that not only help reduce significantamounts ofC02 and build many houses forthose inneed but also be able tomake affordable housing scalable. This object issolved with the features ofthe independent Claims. The invention relates to a method forthe construction of buildings, inwhich a building iserected from a number of prefabricated building elements on a pre- constructed soleplateon a constructionsiteinaccordance witha predetermined construction plan: Firsta microfactory withatleasta partoftheequipment, preferablywitha large part of the equipment, most preferably with the entire equipment, which requiredforthe production ofthe buildingelements and forthe assembly ofthe building and which is accommodated in at least one transport Container, preferably designed in the manner of a Standard Container or large-capacity Container, istransported tothe construction siteby means ofa transport vehicle, preferably by means of a road-bound transport vehicle and / or by means of a singlejourney. Furthermore, the at least one transport Container isunloaded atthe construction siteand the microfactory isset up and prepared ready for Operation, whereby the building elements required for the construction of the building are manufactured by means of the microfactory on site at the construction preferably autonomously, most preferably by means of at least one autonomously operating material processing machine äs partofthe equipment and atleastone autonomously operating material handling device äs partofthe equipment and by using starting material to be machined and / or processed by means thereof.

And furthermore, at least one autonomously operating assembly robot provided äs part ofthe equipment, which issuitable and designed toassemble the building elements on the pre-constructed soleplate in a manner corresponding to the predetermined construction plan, preferably toassemble them insuch a way thatthe buildingelements are detachably connected toone another during assembly, so that the building elements are dismountable for theirreuse. The invention embodies a paradigm shift in construction practices, offering a comprehensive solution that addresses the intertwined challenges of the housing and climate criseswhile ensuring scalability and affordability inhousing Provision. By leveraging a novel approach centered around the establishment ofa microfactory directly atthe construction site,the invention revolutionizes the traditional construction process, delivering unprecedented beneftts across multiple fronts. Firstand foremost, the Integration of a microfactory equipped with advanced machinery represents a pioneering advancement inconstruction technology. By consolidating the production of building elements and the assembly process within a compact and transportable unit, our method streamlines the constructionworkflow, significantlyreducing logisticalcomplexitiesand resource inefficiencies. This not only enhances operational efficiency but also minimizes carbon emissions associated with transportation, thus contributing to the overarching goal ofdecarbonizing the builtenvironment. Moreover, the localized production of building elements offers a distinct advantage in terms of adaptability and customization. By fabricating components on-site, our method empowers builders totailordesigns tospecific project requirements with unprecedented precision. This flexibility not only facilitates the realization of diverse architectural visions but also enables the Integration of sustainable materials and construction techniques, further enhancing the environmental sustainabilityofthe bulltenvironment. Furthermore, the deployment of autonomously operating materiat processing and handling devices underscores our commitment to innovation and automation. By harnessing cutting-edge robotics technology, our method not only accelerates the construction process butalso minimizes relianceon manual labor, thereby addressing labor shortages and productivity constraints thathave lang plagued the construction industry. This not only improves construction efficiency but also enhances worker safety and well-being, creating a more sustainable and equitable construction ecosystem. Additionally, the utilization of autonomously operating carrying and assembly robots represents a transformative leap in construction methodology. By automating the transportation and assembly of building elements, our method ensures precision and consistency in construction, reducing the risk of errors and rework while expediting project timelines. Moreover, the detachable connection of building elements facilitates ease ofdisassembly and reusability, promoting circulareconomy principles and mitigating the environmental impact ofconstructionwaste. To summarise, the method according to the invention embodies a holistic approach to building that overcomes the conventional dichotomy between affordable housing and environmental sustainability. By synergistically addressing the challenges posed by the housing and climate crises, the invention not only reconciles the paradoxical relationship between the two but also paves the way for a future where both imperatives are harmoniously balanced. With itsinnovative blend oftechnology, efficiency,and sustainability, the inventive method represents a transformative solution that holds the Potential to revolutionize the construction industry and reshape the built environment forgenerations tocome. According to a preferred embodiment, the microfactory has at least one autonomously operating material processing machine, preferably a machine tool, most preferably a CNC-controlled machine tool, arranged inthe at least one transport Container, with which the starting material required for the manufacture of the building elements can be machined in a programme- controlled and autonomous manner. The microfactory furthercomprises atleast one autonomously operating material handling device, preferably arranged in the at least one transport Container, with a to-be-machined starting material, preferably a to-be-machined sheet timber and / or a to-be-machined insulation material, being autonomously fed to the at least one material processing machine by means ofthe at leastone material handling device. The machined starting material, preferably machined sheet timber and / or machined insulation material, isautonomously removed from the at least one material processing machine by means ofthe at leastone material handling device. Furthermore, the atleastone material handling device autonomously processes themachined starting material, preferably the machined sheet timber and / or the machined insulation material, necessary with the additional use of at least one further building material, intoprefabricated building elements and preferably deposits them at a predetermined location. The preferred method offers a refined and sophisticated approach to on-site construction through the integration of enhanced functionalities within the microfactory. Central to this isthe incorporation of at least one autonomously operating materiai processing machine within the microfactory, specifically a machine tool, preferably a CNC-controlled machine tool. This addition empowers the microfactory to autonomously machine the starting material required forthe manufacture of building elements ina precisely controlled and programmable manner, thereby ensuring unparalleled accuracy and consistency inthe fabrication process. Thus, a machine tool according tothe invention can be preferably defined äs a machine drivenby powerthat cuts,shapes, orfinishesmaterials.A CNC control (Computerised Numerical Control) isan automatic control System that isused in the production and processing of workpieces. These controls are usually integrated intomachine tools such äs milling machines, lathes, grinders and other CNC machines. The CNC control System works by coordinating and controlling the movement of the machine to perform the desired machining operations. The movements ofthe machine along multiple axes are precisely controlled based on digital instructions generated by a Computer. These instructionsare provided intheform ofnumerical codes (G-code orM-code) that define the positions and movements ofthe machine. The CNC control reads these codes and interprets them to execute the corresponding movements of the machine. This enables high precision, repeatability and efficiency in the production ofworkpieces, äs the movements ofthe machine can be controlled very precisely.A programme-controlled material processing machine ofthistype therefore enables simple, precise and autonomous production of the building elements required forthe construction ofthe building. Furthermore, the inclusion of at least one autonomously operating material handling device withinthe microfactory enhances itsoperational efficiencyand autonomy. This device, preferably situated within the transport Container, facilitatesthe seamless transportation ofto-be-machined starting material tothe material processingmachine and thesubsequent removal ofmachined material, without the need for human Intervention. This streamlines the production process, minimizingdowntime and maximizing productivity. Moreover, the autonomous processing capabilities of the material handling deviceextend beyond mere transportation, encompassing thetransformation of machined starting material, such äs forexample sheettimber and / or insulation material, into prefabricated building elements. This autonomous processing, supplemented by the potential use of additional building materials ifrequired, underscores the versatility and adaptability of the microfactory, enabling to accommodate a diverse ränge ofconstruction needs and specifications. In summary, the method according to this preferred embodiment isa tangible refinement ofthe general method ofthe invention äs outlined above, leveraging advanced technologies and enhanced functionalities to further optimize the construction process. By seamlessly integrating material processing and handling capabilitieswithinthe microfactory, thisembodiment notonlyenhances operational efficiencyand autonomy but also facilitatesthe precisefabrication ofprefabricated buildingelements, thereby advancing the overarching goals of sustainability, scalability, and affordability inconstruction. According to another preferred embodiment, the prefabricated building elements each have two spaced outer layers, preferably of sheet timber, most preferably a cross-laminated bamboo sheet, and an intermediate layer, preferably of an insulation material. By employing two spaced outer layers, preferably made of sheet timber, especially in the form of cross-laminated bamboo sheet, along with an intermediate layer of insulation material, the prefabricated buildingelements provide an optimal balance between structural stabilityand thermal insulation.Thisconstruction notonlyensures highstrength and durability ofthe components but also effectively reduces heat loss, leading to improved energy efficiency of the buildings. Moreover, the use of standardized materials enables cost-effective production and assembly ofthe building elements, reducing the overall project costs and enhancing the economic viabilityofthe method. Especiallythe utilizationofthe preferred cross- laminated bamboo underscores the commitment to sustainable construction practice. According toanother preferred embodiment, the method isfurther characterised in that several different building elements are produced by means of the microfactory, inparticular: a plurality of rectangular Standard panels, preferably formed by identical parts and / or invarying sizes,which are suitable and designed to be used by means ofthe at leastone assembly robot ina manner specifiedinaccordance withthe construction plan fortheformation ofbuildingsidewalls and / or fortheformation offloorplates and / or forthe formation of roof surfaces, and / or a pluralityoftriangulär panels, preferably formed by identical parts and / or in varying sizes,which are suitableand designed toform inclined roofconnection surfaces by means ofthe at least one assembly robot ina manner specified in the construction plan, preferably incombination with Standard panels, and / or a plurality ofbeam and / or column panels, preferably formed by identical parts and / or invarying sizes,which are suitableand designed toform wall connection elements, preferably for the connection of building side walls and / or for the connection of floorpanels, by mea.ns of the at least one assembly robot in a manner specified according to the construction plan. The production ofvarious types of building elements by the microfactory allows for customized adaptation to the specific requirements of the construction project. The manufacturing of rectangular Standard panels, triangulär panels, and beam and / or column panels enables flexible design ofthe building structure and architecture according to the specificationsof the construction plan. This facilitatesthe realizationofcomplex architectural concepts and thefulfillment of individualcustomer preferenceswithoutcompromising on efficiencyand quality. Additionally, the use of identical parts to form the different building elements simplifies the production and assembly processes. The standardized building elements can be easilycombined and interconnected, speeding up construction processes and reducing error susceptibility. This results in shortened construction times, improved construction quality, and overall increased productivity and profitability ofthe method. Additionally, thismethod aligns with the principle of carbon-negative construction by breaking buildings down into fundamental building blocks, which are manufactured äs panels to be assembled and disassembled. These panels aredesigned tobe demounted and reconfigured intonew shapes afterthe end of a building's thus mitigating carbon emissions from timber going to Overall, thisembodiment provides an optimal combination ofstructural stability, thermal insulation, flexibility,and efficiency, such that the method meets the requirements forsustainable, scalable, and cost-effective construction, paving the way fora transformative redesign ofthe construction sector. In order to meet the special requirements for the connection to the pre- constructed soleplate in particular, is recommended according to another particularly preferred embodiment that a plurality of rectangular base panels, preferably formed by identical parts and / or in varying sizes, are produced by means ofthe microfactory, which are suitable and designed to be arranged on the pre-constructed soleplate by means ofthe at leastone assembly robot in a manner predetermined according to the construction plan, with the Standard panels then being subsequently connected tothese base panels inthe vertical axis direction upwards. Preferably, the single building elements are detachably connected to one another and possibly to the soleplate by means of at least one fastening element, preferably by means of screw connections. From a general perspective, the detachable connection of single building elements, facilitated by fastening elements such äs screw connections, offers flexibility and adaptability in the construction process. This modularity allows for easy disassembly and reconfiguration of building components, enabling rapid adjustments to design modifications or future expansion requirements. Additionally, the use of detachable connections minimizes construction waste and facilitates material reuse, aligning with sustainable construction practices and reducing environmental impact. From a technical standpoint, the utilization of fastening elements, particularly screw connections, ensures robust and secure connections between building elements and the soleplate. This enhances structural integrity and stability, mitigating risks associated with structural failure or displacement during assembly or in response to external forces. Moreover, the standardized use of fastening elements streamlines assembly processes, reducing labour time and increasing construction efficiency.The abilityto easilydisassemble and reassemble buildingelements also simplifies maintenance and repair activities, allowing for quick and cost- effectiveinterventionsäs needed. According to another preferred embodiment, the at least one material handling device and / or the at leastone transport robot and / or the at leastone assembly robot isor are transported to the construction site by means of the transport vehicle together with the at least one transport Container, being preferably provided thatthe at leastone material handling device and / or the at leastone transport robot and / or the at least one assembly robot isor are accommodated in the at least one transport Container during the transport by means of the transport vehicle. By transporting the at least one material handling device, transport robot and / or assembly robot tothe construction sitealong orwithinthe at leastone transport Container, the method significantlyreduces the need for separate transportation arrangements. This consolidation of transportation efforts not only minimizes fuel consumption and vehicle emissions but also reduces overall carbon emissions associated with constructionactivities.As a result, the method contributes to mitigating the environmental impact of construction projects, aligningwithglobal effortstocombat climatechange. This approach reduces the number oftrips required fortransportation to preferably one single journey, thereby conserving fuel and minimizing environmental disturbance caused by transportation activities. Especially the accommodation of the at least one material handling device, transport robot and / or assembly robot within the at least one transport Container during transportation also optimizes resource utilization and space efficiency and enhances logistical efficiencyand simplifies project planning. Thus, this approach enables better coordination of transportation schedules and facilitates smoother logistics management, resulting in reduced downtime and improved overall project productivity. According to a preferred embodiment, at least two, preferably exactly two, transport Containers designed inthe manner of a Standard Container or large- capacity Container are provided. This means that, for example, one of the transport Containers can be fitted with the at least one material processing machine and another transport Container can be fitted with the rest of the equipment, forexample withthe atleastone material handling device and / orthe at leastone transport robot and / or the at leastone assembly robot. The use of several, especiallytwo, transport Containers notonly offersadvantages interms of stowing the equipment when transporting the required equipment, but also considerable advantages inthe construction ofa microfactory, äs can be seen from the description ofthe following preferred embodiments: According to a specifically preferred embodiment, the transport Containers for forming the ready-to-use respectively ready- for-operation microfactory are placed at the construction site at a distance from each other and with their longitudinal side walls facing each other so that a longitudinal side wall of a firsttransport Container isdisplaced downwards, preferably folded down, in the direction of the floor in such a way that substantially bridges the distance on the floor side between the two transport Containers, preferably bridging insuch a way that the longitudinal side wall forms a further, substantially horizontally extending floorwall, being preferably provided thatthe longitudinal side wall, together with the Container floorwalls of the two mutually associated transport Containers, forms a walkable and / or continuous and / or horizontal microfactory floorwall, and / or a longitudinal side wall ofa second transport Container isdisplaced upwards, preferably folded open, inthe direction away from the floor insuch away that substantiatly bridges the distance on the ceilingside between the two transport Containers, preferably bridging insuch a way that the longitudinal side wall forms a further, substantially horizontal ceilingwall, being preferably provided thatthe longitudinal sidewall, together withthe Container ceilingwalls ofthe two mutually associated transport Containers, forms a common and / or continuous microfactory ceilingwall. Placing the Containers at a distance from each other and orienting their longitudinal side walls facing each other facilitates the creation of a functional microfactory layout with minimal effort. The integration of additional floor and ceiling walls, formed by displacing longitudinal side walls of the transport Containers, enhances also the structural integrityofthe microfactory ästhey can contribute to the stability and robustness of the microfactory, thus ensuring a safe and secure working environment. In summary, the utilizationof multiple transport Containers presents a holistic approach to equipment transportation and microfactory construction. According to another preferred embodiment, at least one of the two Container ceilingwalls and / or the upwardly displaced longitudinalsidewall isequipped on itsouter side with components ofan energy generation System, preferably with atleastone solar panel and / or with atleastone wind turbine and / or with atleast one wind wheel, wherein energy, preferably electricity, isgenerated with the energy generation System, being preferably provided that the energy generated and utilised for the Operation of at least a pari of the equipment, preferably for the Operation of the at least one material processing machine and / orthe atteastone material handling device.The utilizationofthe Containers fordual purposes, äs both the microfactory structure and a platform forenergy generation, offers technical and general advantages. Integrating energy generation components, such äs solar panels and wind turbines, into the Container structure enhances the sustainability and self-sufficiency of the construction process. By harnessing renewable energy sources, the microfactory can generate electricityto power essential equipment, such äs material processing machines and material handling devices. This reduces relianceon external power sources, minimizes operational costs,and enhances operational resilience,ensuring uninterrupted workflow even inremote or off- grid construction sites. Furthermore, the dual-functionality of the Containers reflects a commitment to sustainability and environmental stewardship in construction practices. By incorporating renewable energy generation Systems into the Container structure, the method reduces carbon emissions and environmental impact associated with construction activities. This aligns with global efforts to combat climate change and promotes a more sustainable approach to construction, fostering a greener and more environmentally consciousconstructionindustry. According to another preferred embodiment, at least one ofthe two Container ceiling walls and / or the upwardly displaced longitudinal side wall have or form at least one window. This ensures good visibilityinside the microfactory. This allows forimproved monitoring ofconstruction processes and facilitates natural Ijghting, creating a more comfortable and productive working environment. According to a specificallypreferred embodiment withthissolution, atleastone ofthe two Container ceilingwalls and / orthe upwardly displaced longitudinal side wall isorare atleast partiallypivotable upwards from itssubstantially horizontal basic orientation inthe direction away from the transport Containers in such a way that inthe pivoted-up statetheyform a roofwith atleastone window. These Windows provide increased headroom and Ventilation,optimizingtheworkspace within the microfactory. Moreover, ample natural light enhances the performance of robots equipped with technologies such äs stereoscopy, ensuring precise and efficient operations. Stereoscopic technology relies, for example, on the use ofcameras orsensors to obtain a three-dimensional view ofthe environment. When sufficientnatural lightisavailable, these cameras or sensors can function more effectively by capturing clear and precise Images. Consequently, the robots can perceive theirsurroundings more accurately and optimize their movements and actions accordingly, leading to improved performance and efficiency. Furthermore, according to another preferred embodiment, a starting material required for the production of the building elements, preferably sheet timber and / or insulation material, isfed to the microfactory via a feed opening which, viewed inthe transverse direction, liesbetween the two transport Containers and, viewed inthe verticalaxisdirection,between the two longitudinal sidewalls displaced into their position of use, and in that the building elements are removed via a removal opening opposite the feed opening. Placing the feed opening between thetwo transport Containers and the longitudinal sidewalls in their position of use optimizes the material flow within the microfactory. This layout minimizes material handling distances, reducing downtime and streamlining production processes. By positioningthe feed opening between the transport Containers and the displaced longitudinal side walls, the method also maximizes the efficient use of space within the microfactory. This spatial optimization enhances workflow efficiency and allows for the incorporation of additional equipmentorworkstations äs needed. Furthermore, thearrangement ofthefeed opening and removal opening oppositeeach otherfacilitates a linear production process flow. This streamlined Operation minimises material handling steps and isparticularly useful forautomated operations. This is the more true in the case of a specific preferred embodiment, according to which the starting material required for the production of the building elements, preferably sheet timber and / or insulation material, isstored inside the microfactory at a defined storage location inthe region of the feed opening, and inthatthe building elements are deposited insidethe microfactory at a defined deposit location inthe region ofthe removal opening. This allows, for example, an arrangement in which the at least one material processing machine isarranged in a lateral region of the microfactory opposite the feed opening and / orthe removal opening. The at least one material handling device can in principle be designed and arranged in different ways. For example, according to a firstembodiment, such away thatthe atleastone material handling device oratleastone material handling device isarranged on the inside ofthe microfactory ceilingwall and / or on the inside of the microfactory floor wall, preferably isarranged in a fixed Position or isforcibly guided and movable atong a System. Or alternatively and additionally insuch a way that the at leastone material handling device or at least one material handling device forms an autonomously controllable component of the at least one material processing machine. Positioning the material handling device insidethe microfactory ceilingorfloorwalls optimizes space utilization and facilitates efficient material movement. Alternatively or additionally, integrating the material handling device äs an autonomously controllable component of the material processing machine enhances operational efficiency. This integration streamlines production processes and enhances overall automation withinthe microfactory. According to another preferred embodiment, the at leastone matehal handling device oratleastone material handling device isformed by a material handling robotwith atleastone gripperarm which ismovable indifferentspatial directions and / or isextendable ina program-controlled manner. The abilityofthe gripper arm tomove indifferentspatial directionsand / or tobe extendable ina program- controlled manner enhances itsversatilityinhandling various types ofmaterials and components within the microfactory. This versatility enables efficient manipulation ofmaterials regardless oftheir size,shape, ororientation, thereby optimizing production processes. The precise control over the movement and / or extension ofthe gripper arm ensures accurate positioning and manipulation of materials with high precision. This minimizes the riskoferrors ordamage during handling processes, leading toimproved product qualityand consistency. Furthermore, ispreferred that the at leastone carrying robot isformed by an autonomously travelling vehiclewhich travels autonomously to a predetermined location atthe microfactory and isloaded there autonomously, preferably by the orby a material handling device and / or by a loading device forming partofthe autonomously travellingvehicle,witha defined number and / or a defined type of the prefabricated building elements. Afterthe autonomous loading process, the autonomously travelling vehicle travels autonomously to a predetermined location on the pre-constmcted soleplate and isunloaded there autonomously, preferably by an unloading device forming part ofthe autonomously travelling vehicle and / or by at least one autonomously travelling unloading robot, preferably in such a way that the building elements are deposited at a predetermined location. The utilization of at least one autonomously travelling vehicle formaterial handling offers significantadvantages interms ofefficiency, precision, and automation, streamlining operations within the microfactory and enhancingoverall productivity.The automated loading processensuresefficient and precise handling of prefabricated building elements, minimizing the riskof errors and optimizing workflow. Furthermore, the precise unloading process ensures that building elements are deposited accurately at predetermined locations, facilitating seamless Integration intothe construction process. Inprinciple,the at leastone unloading device can be formed by a separate unit. However, for a high level of functional Integration, which helps to save components and resources, the at least one loading device can be formed by the at least one assembly robot inan advantageous dual function. Preferably, the at leastone autonomously movable assembly robot has atleast one gripper arm which is movable in different spatial directions and / or extendable in a program-controlled manner, by means of which the prefabricated building elements are gripped, preferably by means ofa vacuum gripper unit, and placed in a manner corresponding to the predetermined construction plan. The use of autonomously movable assembly robots with movable and extendable gripper arms enhances flexibilityand precision in handling prefabricated building elements. This allows for efficientgripping and placement of elements according to the predetermined construction plan, contributing to streamlined construction processes and ensuring accurate assembly. According to a specificallypreferred embodiment, the at leastone gripperarm or at least one additional gripperarm has assembly tools, by means ofwhich the building elements placed in accordance with the construction plan are detachably fastened. The Integration of assembly tools into the at least one gripper arm ofthe assembly robot enables the effective attachment of building elements according to the construction plan. This capability enhances the assembly process by allowing for the immediate fastening of elements upon placement, reducing theneed foradditional manual labour and improving overall construction efficiency. According to another specifically preferred embodiment, the at least one assembty robot and / or another separate assembly robot isor are also suitable and designed to autonomously assemble and disassemble further structural elements, preferably Windows and / or cladding elements and / or fa^ade elements. This expanded functionality streamlines the construction process by automating additionalassembly tasks, reducing relianceon manual labour,and ensuring consistent qualitythroughout the construction project. According to another specifically preferred embodiment, the at least one autonomously operating carrying robot simultaneously forms the at least one autonomously operating assembly robot. This preferred integrated approach streamlines material handling and assembly processes, reducing the need for separate robotic Systems and enhancing overall coordination and synchronizationoftasks.As a result, construction timelinesare expedited, and project efficiency ismaximized. According to preferred embodiment, the at least one transport Container is a cuboid freight Container, preferably a 20-foot Container, preferably with the following dimensions: ExteriorDimensions (infeet):20' long x 8'wide x 8'6" high ExteriorDimensions (inmetres): 6.10m lang x 2.44m wide x 2.59m high InferiorDimensions (infeet): 19'4" lang x 7'9"wide x 7'10" high InteriorDimensions (inmetres): 5.898m long x 2.352m wide x 2.393m high Utilizinga cuboid freightContainer, preferably a 20-foot cuboid freightContainer, ensures compatibility with existing transportation infrastructure and logistical Systems. Standard dimensions allow for seamless Integration into shipping networks, simplifying the transportation process and reducing logistical complexities. The dimensions of the Container, both exterior and interior, are carefully designed to maximize space utilization while adhering to Standard shipping regulations. This ensures efficient packing of the microfactory equipmentwithin the Container, minimizing wasted space and reducing shipping costs. Furthermore, the standardized dimensions facilitate handling and maneuverability ofthe Container during loading, unloading, and transportation. Compatibility with common handling equipment, such äs cranes and simplifies logistics and reduces the risk of delays or damage during transit. Standardized Container sizes result in lower shipping costs, making transportation of the microfactory more economical without compromising on equipment capacity or functionality. Compliance with Standard Container dimensions also ensures adherence to transportation regulations and safety Standards. This minimizes regulatory hurdles and facilitatessmooth transit of the microfactory to the construction site, avoiding potential delays or complications associated with non-compliant shipments. The same principle applies to the use of 40-foot Containers, which may reduce the number of Containersneeded. In a further aspect, the object described above issolved by a System forthe construction of buildings, in particular by a System for the construction of a building according to a method described above. The resultingadvantages are identical to those of the method, so that reference ismade to the previous explanations inorder to avoid repetition. The invention isfurther explained inmore detail and by way of example only with reference to drawings. These drawings show: Fig.la to 11 illustrate schematically and by way ofexample the various stages inthe manufacture ofa building according tothe invention, Fig.2a exemplary and schematic a view of the feeding of a material processing machine with sheet timber tobe processed, Fig.2b schematic and exemplary an assembly process carried out by means of a material handling device for producing a building element, Fig.2c shows a schematic example of an assembly robot during the assembly of prefabricated building elements according to a given construction plan, Figure 3a shows a schematic and exemplary front view of an exemptary building structure with different building elements, Figure 3b shows a schematic and exemplary exploded view, alternative to Figure 3a, showing the various prefabricated building elements assembled toform an alternatively constructed wall. Inthe following, Figures 1a to 11are used to explain inmore detail, by way of example and schematically, an embodiment of a method for constructing a building, inwhich a building 28 isconstructed from a plurality of prefabricated building elements 16 on a pre-cronsucted soleplate 24 of a construction site 5 inaccordance with a predetermined construction plan. In a firststep (Figure 1a), a microfactory 1, preferably with orat least a large part of the equipment required to manufacture the building elements and to assemble the building 28, which isaccommodated here, for example, intwo transport Containers 2, 3 designed in the manner of a Standard Container or large-capacity Container, istransported tothe constmction site5 (see Figure b) by means ofa transport vehicle 4, here, forexample, by means ofa road-bound transport vehicle inthe form of a truck and preferably by means ofa single orjourney. The two transport Containers2,3 are here exemplary cuboid 20-foot Containers, so-called freightContainers,which preferably have the following dimensions: Exterior Dimensions (infeet): 20' long x 8'wide 8'6" high ExteriorDimensions (inmetres): 6.10m lang x 2.44m wide x 2.59m high InteriorDimensions (infeet): 19'4" lang x 7'9"wide x 7'10" high Interior dimensions (inmetres): 898m long x 352m wide x 393m high As can be seen from Figure 1b and Figure 1c,thetwo transport Containers 2, 3 are unloaded atthe construction site5 and then the microfactory isset up and prepared for Operation. As these are Standard Containers, the transport Containers 2, 3 can be unloaded using conventional trucks As can be seen inparticularfrom the combined view of Figures 1c and 1d, the two transport Containers 2, 3 are placed next to each other at a distance and with theirlongitudinal side walls 7, 8 facing each other toform the ready-to-use microfactory atthe construction site5 insuch away thatone longitudinal side wall 7 of the firsttransport Container 2 bridges the distance between the two transport Containers 2, 3 on the floorside ina state inwhich isfolded down towards the floor.The bridging takes place insuch a way that the longitudinal side wall 7 forms a further, horizontally extending floor wall, so that the longitudinal side wall 7 together with the two further Container floorwalls 9, 10 ofthetwo associated transport Containers 2,3 form a walkable, continuous and horizontal micro-factory floor wall. Furthermore, a second longitudinal sidewall 8 ofthe second transport Container 3 isfolded upwards so that bridges the distance on the ceilingside between the two transport Containers 2, 3 insuch a way that the longitudinal side wall 8 forms a further, horizontally extending ceilingwalland the longitudinal sidewall 8, together with the Container ceiling walls of the two associated transport Containers 2, 3,forms a common and continuous micro-factory ceilingwall. As can also be seen from Figure 1e, inthe example shown here, Container ceilingwalls 11, 12 and the longitudinal side wall 8 äs a further Container ceiling wall can also be swivelled upwards from their essentially horizontal basic orientation (see Figure 1d) in the direction away from the two transport Containers 2, 3.This allows them toform a dormer window with several viewing Windows 13 atthe frontwhen swivelledopen. As isonly indicated extremely schematically inFigure 1e bythe labelling "Solar", both the Containerceilingwalls 11, 12 and the upwardly opened longitudinalside wall 8 äs a furtherContainerceilingwallcan be equipped on theiroutersidewith components ofan energy generation System, forexample with solar panels.As a result, energy, preferably electricity, can then be generated with an energy generation System not shown here, which inturn can be used, at least in part, äs energy forthe Operation ofat leastsome ofthe equipment described inmore detail below. As an alternative to solar panels, wind turbines orwind wheels can also be provided on the roofside,forexample, butthisisnotshown furtherhere. Hydrogen-driven or hydrogen-based energy generation Systems might be used here inaddition or alternatively (also not shown). As can be further seen from Figure 1f, when the microfactory has been completely assembled and setup and prepared forOperation,a startingmaterial required forthe manufacture ofthe buildingelements, forexample sheet timber 14, can be fed tothe microfactory via a feed opening 15 which, viewed inthe transverse direction, islocated between the two transport Containers 2, 3 and, viewed inthe vertical axis direction, between the two longitudinal side walls 7, 8 displaced intotheirposition of use. Afterthe prefabricated building elements 16 have been manufactured in the microfactory 1, they are removed from the microfactory viaa removal opening 17 opposite thefeed opening 15 and made available forpick-up and collection,äs willbe explained inmore detailbelow. The sheet timber 14 can be delivered separately to the construction site 5,äs can the building materials and construction materials required for the manufacture of the prefabricated building elements 16, such äs insulation material, fastening elements, etc. As indicated schematically inFigures 1a to 1d by the labelling ofthe transport Containers 2, 3 with the designations "CNC" and "arm", at least one autonomously operating material processing machine, preferably at least one CNC-controlled machine tool 18, can be accommodated in the transport Container2, forexample, and transported tothe construction site5.The CNC- controlled machine tool 18 isonlyshown very schematically and äs an example in Figure 2a. With this CNC-controlled machine tool 18, the starting materials required for the manufacture of the building elements 16, such äs the sheet timber 14 (see Figure 2a), can be processed, for example cut to size, in a programme-controlled and autonomous manner. Inthe transport Container 3,which islabelled "arm", on the other hand, parts of the other equipment inparticular can be accommodated and transported to the construction site 5, forexample, such äs a material handling device, which described inmore detail below and isformed by at least one material handling robot 19, at leastone carrying robot20 and at leastone assembly robot 21 ,the functionsofwhichare also described inmore detailbelow. As can be seen in particular from Figures 2a and 2b, the at least one material handling robot 19 isequipped with a gripperarm 22 movable indifferent spatial directions, which is moved program-controlled in such a way that autonomously feeds a sheet timber 14 to be processed tothe machine tool18, äs shown only extremely schematically and inprincipleinFigure 2a. As further schematically indicated inFigure 2a, the material handling robot19 can, forexample, be arranged ina fixed positionon the insideofthe microfactory floorwall, forexample inthe vicinityofthe machine tool 18, inorder not only to feed withthe starting material tobe processed, such äs the sheet timber 14 to be processed, äs described above, but also to remove the processed starting material, such äs the processed sheet timber 14, from äs schematically indicated inFigure 2b. As can also be seen in Figure 2b, the material handling robot 19 is further designed, for example, in such a way that also processes the processed starting material, forexamplethe processed sheettimber 14,togetherwith other building materials and construction materials, shown here only äs an example by the insulation material 23, ina program-controlled and autonomous manner tothe prefabricated building elements 16 and deposits them ata predetermined location or at a defined deposit location inthe area ofthe removal opening 17. There they are then picked up by an autonomously operating carrying robot 20 (see Figure 1g) and transported to a pre-constructed soleplate 24 at the constructionsite5. As can also be seen inFigure 2b, the prefabricated buildingelements 16 have, for example, two spaced outer layers of sheet timber 14 and an intermediate layer of insulation material 23, which are screwed together, for example. This can also be done program-controlled and autonomously by the material handling robot 19. The carrying robot 20, which isonly shown extremely schematically in Figure 1g, isformed, forexample, by an autonomously travellingvehiclewhich travels autonomously toa predetermined locationon the microfactory (see Figure 1f) and isloaded there autonomously, forexample by the material handling robot 19 and / or by a loading device 25 forming part of the autonomously travelling vehicle,forexample a gripperarm orthe like,witha defined number ora defined type of the prefabricated building elements 16. After the autonomous loading process, the carrying robot 20 formed by the autonomously travelling vehicle then drives autonomously to a predetermined point on the pre-constructed soleplate 24 and isunloaded there autonomously, forexample by the loading device 25 forming part ofthe autonomously travelling vehicle, which also forms an unloading device, and / or by at least one autonomously travelling unloading robot notshown here.The unloading process ispreferably carried out insuch a way that the prefabricated building elements 16 are deposited at a predetermined location, where they are then picked up by the autonomously operating assembly robot 21,which forms partofthe equipment, and, äs shown only very schematically inFigure 2c, placed, forexample, on the pre-constructed soleplate 24 ina manner corresponding tothe predetermined construction plan, insuch a way that the buildingelements 16 are detachably connected toeach other during assembly (see also Figures 1i and which show different construction Steps), so that the building elements 16 can also be dismantled again forreuse (see Figure The at least one autonomously operating assembly robot 21 preferably has a program-controlled gripper arm 26 that can be moved in different spatial directions and / or is an extendable gripper arm 26, by means of which the prefabricated building elements 16 can be gripped, which isparticularly evident from Figure 2c. For this purpose, the gripper arm 26 can be equipped with a vacuum gripper unit,forexample. Inaddition, the gripper arm 26 can have assembly tools by means ofwhich the building elements 16 placed according to the construction plan are detachably fastened together, forexampte by means ofa screw connection. As can be seen inparticularfrom the combined view ofFigures 1h to 1j,the at least one assembly robot 21 can be designed such that not only places or arranges the prefabricated building elements 16 on the pre-constructed soleplate 24 in a predetermined manner inaccordance with the construction plan and detachably fastens them (Figure 1h), but that also assembles the floorplates 27 present inthe building 28 (Figure 11)and then, starting from the floorplate 27, assembles the other parts of the building, such äs the roof surfaces 29 (Figure After the building 28 has been completed by assembling the prefabricated buildingelements 16 produced by the microfactory on siteatthe construction site5,the buitding28 can be provided withfurtherbuildingelements, which can be, for example, done by subcontractors. These include, for example, the application of a roof cladding element 31, forexample roof tilesor the like, or the arrangement of Windows or fa^ade elements 30. Alternatively, these additional elements can ofcourse also be installed autonomously on the building 28 by the assembly robot 21 or a further separate assembly robot, which isnot shown here. The particular advantage of the solution according to the invention lies particular inthe fact that, äs shown only very schematically in Figure 11,the building 28 can also be dismantled again by reversing the building assembly Steps described above, in particular in connection with Figures 1g to 1k, autonomously by means of at teast one assembly robot 21. This isdone in particular by simply loosening the detachable connections between the individual building elements 16 orthesoleplate24, sothatthe building elements 16 are available again fora new building construction, forexample ata different location. As willnow be explained inmore detail merely by way ofexample and by way of Illustration with reference to Figures 3a and 3b, several different building elements 16 can be produced with the microfactory 1. For example, a plurality of rectangular Standard panels B, preferably formed äs identical parts, which can be used, forexample, äs shown inFigures 3a and 3b, toform building side walls and / or toform floor plates 27 and / or toform roof surfaces 29. In addition, a plurality of triangulär panels D1 and D2, preferably designed äs identical parts (äs regards D1) and ina varying size(äs regards D2 with respect to D1), which can form sloping roof connection surfaces, for example in combination with other prefabricated building elements. Furthermore, a plurality of beam and / or column panels C1 and C2, again preferably designed äs identical parts (äs regards C1 and C2) and invarying sizes (äs regards C1 with respect to C2), which can form wall connection elements forthe connection of building side walls and / or forthe connection of floorpanels, äs also shown by way ofexample only inFigures 3a and 3b. And finally, a plurality of rectangular base panels A1, A2 and / or A3, preferably formed äs identical parts (äs regards A1 and A3) and in a varying size (äs regards forexample A2 and A3 with respect toA1 which are suitably designed to be arranged on the pre-constructed soleplate 24 ina predetermined manner according to the construction plan and, äs shown merely exemplarily and schematically in Figure 3a, also on the floorplate 27, inorder to then connect further prefabricated building elements to these. As already explained above, the individual building elements 16 are detachably connected to each other and, ifnecessary, to the soleplate 24 by means of at least one fastening element, for example by means of detachable screw connections,which are notshown indetail here.
