Description

FIELD OF THE INVENTION

The present invention relates, in various embodiments, to technology for configuration of a digital twin for a building or other facility via BIM (Building Information Modelling) data extraction and asset register mapping. Other embodiments relate to technology configured to provide data flow management for defining of digital records representing building infrastructure based on building information modelling data.

BACKGROUND

Any discussion of the background art throughout the specification should in no way be considered as an admission that such art is widely known or forms part of common general knowledge in the field.
Modern buildings have a wide range of connected devices, for example devices managed via a Building Management System (BMS), and other Internet of Things (IOT) devices. Configuration of a user interface that provides convenient access to those devices across building in a logical manner is a complex and error-prone task. For example, it typically requires identification of all devices in a building, and individual mapping of those to particular locations defined in a control interface.
Building Information Modelling (BIM) technology is widely used for the purposes of building design, allowing collaboration over building design, for example in the context of enabling users to add and information objects representing building components to architectural diagrams. However there are often technical challenges associated in leveraging models created through such software for purposes beyond the design phase of a building.

Thus, appearances of the phrases “in one embodiment”, “in some embodiments” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment, but may. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner, as would be apparent to one of ordinary skill in the art from this disclosure, in one or more embodiments.
As used herein, unless otherwise specified the use of the ordinal adjectives “first”, “second”, “third”, etc., to describe a common object, merely indicate that different instances of like objects are being referred to, and are not intended to imply that the objects so described must be in a given sequence, either temporally, spatially, in ranking, or in any other manner.
In the claims below and the description herein, any one of the terms comprising, comprised of or which comprises is an open term that means including at least the elements/features that follow, but not excluding others. Thus, the term comprising, when used in the claims, should not be interpreted as being limitative to the means or elements or steps listed thereafter. For example, the scope of the expression a device comprising A and B should not be limited to devices consisting only of elements A and B. Any one of the terms including or which includes or that includes as used herein is also an open term that also means including at least the elements/features that follow the term, but not excluding others. Thus, including is synonymous with and means comprising.
As used herein, the term “exemplary” is used in the sense of providing examples, as opposed to indicating quality. That is, an “exemplary embodiment” is an embodiment provided as an example, as opposed to necessarily being an embodiment of exemplary quality.
The description below refers to “systems” and “modules”. The term “module” refers to a software component that is logically separable (a computer program), or a hardware component. The module of the embodiment refers to not only a module in the computer program but also a module in a hardware configuration. The discussion of the embodiment also serves as the discussion of computer programs for causing the modules to function (including a program that causes a computer to execute each step, a program that causes the computer to function as means, and a program that causes the computer to implement each function), and as the discussion of a system and a method. For convenience of explanation, the phrases “stores information,” “causes information to be stored,” and other phrases equivalent thereto are used. If the embodiment is a computer program, these phrases are intended to express “causes a memory device to store information” or “controls a memory device to cause the memory device to store information.” The modules may correspond to the functions in a one-to-one correspondence. In a software implementation, one module may form one program or multiple modules may form one program. One module may form multiple programs. Multiple modules may be executed by a single computer. A single module may be executed by multiple computers in a distributed environment or a parallel environment. One module may include another module.

The term “predetermined” means that something is decided in advance of a process of interest. The term “predetermined” is thus intended to refer to something that is decided in advance of a process of interest in the embodiment. Even after a process in the embodiment has started, the term “predetermined” refers to something that is decided in advance of a process of interest depending on a condition or a status of the embodiment at the present point of time or depending on a condition or status heretofore continuing down to the present point of time. If “predetermined values” are plural, the predetermined values may be different from each other, or two or more of the predetermined values (including all the values) may be equal to each other. A statement that “if A, B is to be performed” is intended to mean “that it is determined whether something is A, and that if something is determined as A, an action B is to be carried out”. The statement becomes meaningless if the determination as to whether something is A is not performed.
The term “system” refers to an arrangement where multiple computers, hardware configurations, and devices are interconnected via a communication network (including a one-to-one communication connection). The term “system”, and the term “device”, also refer to an arrangement that includes a single computer, a hardware configuration, and a device. The system does not include a social system that is a social “arrangement” formulated by humans.
At each process performed by a module, or at one of the processes performed by a module, information as a process target is read from a memory device, the information is then processed, and the process results are written onto the memory device. A description related to the reading of the information from the memory device prior to the process and the writing of the processed information onto the memory device subsequent to the process may be omitted as appropriate. The memory devices may include a hard disk, a random-access memory (RAM), an external storage medium, a memory device connected via a communication network, and a ledger within a CPU (Central Processing Unit).

DETAILED DESCRIPTION

The present invention relates, in various embodiments, to technology for configuration of a digital twin for a building or other facility via BIM (Building Information Modelling) data extraction and asset register mapping. This is particularly relevant for the purposes of increasing efficiency and reducing risks of data errors in the context of configuring a digital twin interface for a building. Also described herein is technology configured to provide data flow management for defining of digital records representing building infrastructure based on building information modelling data. This is particularly relevant for the purposes of increasing efficiency and reducing risks of data errors in the context of configuring a digital twin interface for a building.
For the purposes of this description, the term “building” is used to generically describe a building or other facility that is designed and subsequently constructed. For example this may be a building, collection of buildings, hybrid indoor/outdoor space, sports stadium, outdoor space, and so on. A building is comprised of a plurality of “assets” defined in BIM model data for the building, based on a design phase whereby that BIM model data is generated. These assets include standard infrastructure assets (for example walls, floors, ceilings, etc.) and connected assets (for example sensors, controllers, IOT devices, cameras, access control devices, HVAC components, and so on).
The term “digital twin” or “digital twin interface” describes a computer platform that provides a user, for example a person with a scope of responsibility in relation to an in-use (i.e. occupied and operational) building, allowing that user to view the building as a rendered 3D model, and from within that model identify and access various devices within the building (for example reading values from sensors, initiating control instructions, and so on). That is, a user is enabled to, via a viewer module, view and navigate a building via three dimensional renderings, which show both architectural features and building assets. Where those assets are connected assets (for example assets that are networked, for instance via an IOT or BACnet arrangement), data and/or control functions are made available via the digital twin interface. A digital twin is distinguished from a building management system in the sense that it provides a higher technology layer that allows a user to access functionalities that optionally include conventional BMS data, but also data and information from a wider range of sources, and do so via a common 3D navigation interface.
The technology described below is described by reference to a three-phase lifecycle for a building:

- A design phase. At this phase, the building is designed, via a process that includes the generation of BIM data.
- A construction phase. At this phase, the physical building is physically constructed, including installation (and, where relevant, connection) of assets defined in the BIM data.
- A utilisation phase. This generally described when the building is in-use, for example when it is occupied by tenants.

It will be appreciated that these phases are not always temporally distinct, and may have some overlap.
Some embodiments relate to technology which overcome technical challenges in progressing valuable data from the design phase through to the utilisation phase, particularly in the context of generating and implementing a digital twin for the building. It will be appreciated that, during the construction and completion phase of a building, there can be a large number of people working on various aspects of asset installation and commissioning, leading to a significant amount of complexity and error susceptibility in terms of understanding the actual links between a designed building in a data file and a completed building in the real world.
One embodiment provides a method for configuration of a digital twin for a building. The method includes identifying one or more BIM model files for the building, which are prepared during the design phase, and subsequently completed and approved via a central validation process. Each of the BIM model files includes data sets representative of respective physical networked assets that are to be installed in the building. Each of the data sets has a unique identifier (UID), defined by a software program that is used to generate the model file. An example of known software which is used in a design phase for creation of BIM model data is Autodesk Revit (hereon “Revit”), and the technology is described by reference to that software.
The method includes two separate parallel processes: an asset register generation process, and a digital twin generation process.
The asset register generation process includes extracting the data sets from the one or more BIM model files thereby to populate an asset register. This causes the asset register to maintain an asset record for each of the networked physical assets proposed for the designed building. Each asset records includes the respective UID from the BIM model file. The asset register generation process also includes providing an interface that enables updating of the asset register during construction of the building and physical installation/configuration of the networked physical assets. Importantly, each of the asset records upon completion includes a data field populated to contain information that enables access to data and/or a control interface for the represented physical networked asset. Technology and methods supporting the asset register generation phase according to embodiments is described in detail further below.
The digital twin generation process includes performing a conversion of at least subset of the one or more BIM model files for the building thereby to define one or more visualisation files for the building. For example, this includes an Autodesk Revit to AutoCad conversion process, and then a manual process by which 3D visualisations are prepared in AutoCaD, these being suitable for navigation via a 3D visualisation interface.
The visualisation files are configured to be rendered via a 3D navigation interface, in the form of a digital twin interface, presented at a client terminal thereby to enable a user of that client terminal to navigate and view a 3D visualisation of the building. These files additionally include data points that are positioned at locations in the 3D visualisation associated with the networked physical assets, and respectively configured to cause displaying of obtained data based on the respective UID from the BIM model file.
During execution of the digital twin interface, a data mapping module is configured to facilitate the displaying of the obtained data. This includes: (i) identifying an asset UID provided from the visualisation file; (ii) determining, from the asset register, the value for the data field populated to contain information that enables access to data and/or a control interface for the represented physical networked asset; and (iii) causing mapping of data and/or control interface for the represented physical networked asset to the 3D navigation interface. In this manner, data is automatically mapped from the physical networked assets to the 3D visualisation interface.
In some embodiments the data field populated to contain information that enables access to data and/or a control interface for the represented physical networked assets includes a BACnet identifier (or BACnet address) defined in respect of a BACnet that is configured for the building. The data field may also be populated with information such as a non-BACnet network location and/or hyperlink.

Example System

FIG. 1A illustrates a technology framework including an asset register management system 100. System 100 is configured to enable workflow management in building construction, including workflow management for the configuration of data in an asset register 110 based on data defined in BIM model files during the design phase.
Asset register 110 is a database (or collection of databases) configured to maintain a plurality of asset records (111A to 111 n) associated with a common building project. In some embodiments, asset register 110 maintains asset records for a plurality of building projects, with all asset records having identifiers associating them with a particular one of those building projects. Asset records are created to each represent, in data form, a physical asset, which is represented in BIM data during the design phase and physically installed as a physical asset during the construction phase. For example, the assets include standard infrastructure assets (for example walls, floors, ceilings, etc) and connected assets (for example sensors, controllers, IOT devices, cameras, access control devices, HVAC components, and so on).
Each asset record has a plurality of associated data fields, for example asset record 111A as data fields 112A-A to 112A-n. The number of data fields (and meaning of the individual data fields) is dependent on a given attribute of the asset, for the present example being the asset type. Asset register 110 is configured such that each asset record is configured to contain a predefined set of data fields associated with that asset type that are able to be populated with respective data values. In a preferred embodiment the set of data fields for a given asset type is determined by reference to a COBie specification for that asset type. Each asset record additionally includes a global unique identifier (GUID) which is unique in asset register 112.
System 100 includes a permissions management module 105. The permissions management module is configured to maintain permissions data 107 respective of access permissions for a plurality of users. For example, data 107 associates user login credentials with user permissions (for example permissions based on a user's defined scope-of-responsibility, or SOR). Permissions may be tied to asset record attributes, such as an asset type and/or asset system and/or an asset discipline. This assists in SOR-based permission setting—for example a given user is given access only to HVAC system assets. This may be access in terms of creating new asset records and/or modifying existing asset records, as discussed in more detail further below.
A BIM model data input module 106 is configured to manage the generation of new asset records from BIM model data. In overview, module 106 is configured to enable automated mapping of BIM data for a building project, stored in a plurality of distinct BIM model files (e.g. Revit files), into asset register 110. This would conventionally require an error prone and time-consuming manual process.
An example of known software which is used in a design phase for creation of BIM model data is Autodesk Revit (hereon “Revit”), and the technology is described by reference to that software. Some embodiments of the disclosed technology assists in overcoming technical problems associated with managing asset installation for a building where a plurality of parties are each individually responsible for installations within their own SOR and based on their own Revit files. Embodiments also find application in overcoming technical challenges associated with generation of a digital twin interface for a building from Revit data files. However it should be appreciated that the technology may be used with other software packages, which may also give rise to corresponding technical challenges.
In some embodiments, module 106 is configured to enable automated mapping of BIM data for a building project, stored in a plurality of distinct BIM model files (e.g. Revit files), into asset register 110. This would conventionally require an error prone and time-consuming manual process.
As context, for a given building project, a plurality of users generate respective BIM model files for the building, for example based on their individual SOR (e.g. architectural, plumbing, electrical, HVAC, and so on). In the present embodiment, the BIM model generating users are instructed to follow a predefined metadata attribute assignment protocol for assets included in their respective models. This is preferably performed when adding assets to the file, but may be performed at a later stage as a separate metadata management process. The predefined metadata attribute assignment protocol is matched to a data extraction script described further below. In one embodiment, the predefined metadata attribute assignment protocol sets the following minimum metadata requirements for each asset in a BIM model file:


Asset Parameter	Comments

PROJECTID.Name	Named in line with equipment type
	protocol (COBie)
PROJECTID.Category	Asset Discipline group that the item
	belongs to i.e. Mechanical/Hydraulic
PROJECTID.AssetIdentifier	Specification number (COBie)
PROJECTID.Location	Named as space.name or Level.Room
	01.01 room 1 on level 1
PROJECTID.Type	Named in accordance with a predefined
	equipment type protocol
PROJECTID.System	E.g. Chilled Water flow. Name of System
	as per the system naming protocol.
	System optionally adheres to a parent-
	child naming convention, or other
	convention.

In each case, the “PROJECTID” component is a unique identifier for a given building project (for example the PROJECTID component may be derived from a building name or address.
In practice, prior to completion of the design phase, all BIM model data files for the building project are collected centrally and cross-validated, thereby to ensure that they are compatible for construction purposes. This also allows for a preliminary asset count that defines a number of assets for the project that should be expected in the asset register. The cross-validation process also preferably includes ensuring all data files comply with the metadata attribute assignment protocol described above.
FIG. 1A illustrates example design client systems 120A to 120 n. Each of these systems is a computer system that executes BIM model software 121 (for example Revit) and has access to a respective BIM model file 123 (which is typically local stored). A model data extraction module 122 executes as a plugin within the software environment of software 122 (for example as a Revit plugin), which is configured to execute various processes from within that environment.
BIM model data input module 106 is configured to communicate with a plurality of instances of the model data extraction module 122, as these execute at respective remote client systems. An operator of a given one of the systems 120A to 120 n triggers execution of a model data extraction process (for example via accessing a function associated with the plugin). A process associated with asset extraction module 122 is shown in FIG. 2A. This is illustrated by references to a set of processes 200 performed on an example user terminal (for example system 120A), and a set of processes 210 performed by an asset register management system (such as system 100).
Block 211 represents a process including establishing permissions for a plurality of users, based on known scope of responsibility attributes for those users. For example, a set of contractors each associated with the construction phase of a building are identified, and identifying details inputted into a permissions data store maintained by the asset management system. Block 201 represents a process whereby a user accesses a registration interface for the asset management system (for example vis a user interface hosted by a web server and rendered in a user terminal web browser application), and completes a registration process (for example setting/confirming login credentials and so on). In some embodiments process 211 includes inputting of user email addresses, and triggers automated delivery of emails having registration hyperlinks; process 201 is triggered via clicking of such hyperlinks. Block 202 represents a backend process whereby user registration is completed.
Block 202 represents a process by which asset extraction module 112 is downloaded and installed, in this embodiment by way of downloading and installing a Revit plugin. Functionality provided by this plugin is accessible from a plugin specific tab that is subsequently displayed within the Revit software platform. A user accesses that tab at process 203, which causes execution of computer code associated with the plugin.
Block 204 represents a process whereby the plugin performs a permission verification process, which prompts the user to input login credentials corresponding to those defined at block 201. These are uploaded to the asset management system thereby to enable a permission verification backend process 213 via permissions module 105 and permissions data 107. In this manner, the model data extraction module is selectively granted access to transmit data to the BIM data input module, based on a user verification and permission determination process performed by the permissions management module.
Block 205 represents an optional process including setting of asset metadata attributes to filter asset metadata for extraction form the Revit file. This optionally includes automated setting of primary attributes based on user scope of responsibility as determined from the processes of blocks 204 and 213 (preferably based on PROJECT.Type attribute). It optionally includes additional filtering at the discretion of an operator, for example to further limit assets that are of relevance to the operator (for example based on asset location, and so on). In some cases all assets defined in each BIM model data file are extracted without filtering.
Block 206 represents a process including execution of a script defined for the plugin that causes analysis of Revit file 102, thereby to query assets in the model having metadata conforming to the predefined metadata attribute assignment protocol, as described above, based on extraction parameters defined at block 205. That is, the model data extraction module performs a data analysis process in respect of a defined BIM model file thereby to extract a plurality of data sets complying with a predefined metadata schema; The data is then optionally presented for review by the operator at 207, optionally allowing for operator editing of the metadata (with such modifications being implemented in the Revit fie), and the operator provides an instruction to export the data to the asset management system.
The model data extraction module causes transmission of the extracted data sets to the BIM data input module Block 214 represents a process whereby the asset data extracted from the Revit file at 207 is received, and added to a cloud-hosted asset register. As represented by block 217, this allows the data to be accessed via an asset data input module, as discussed further below.
For each of the extracted data sets, the BIM data input module:

- (i) Determines an asset type;
- (ii) Creates a new asset record in the asset register database having predefined set of data fields associated with that asset type, and a GUID defined by data extracted from the BIM model file; and
- (iii) Pre-populates a subset of those data fields based on the predefined metadata schema. For example, a “PROJECT.location” value in the model file extracted metadata is used to automatically populate a “location” field in the asset register record for the relevant asset.

This is performed such that the BIM data input module creates new asset records in the asset register database, for a common building project, based on data contained in a plurality of discrete BIM model files maintained on respective host systems. In effect, asset data defined across a plurality of files by a plurality of collaborating users is extracted directly from the source files into specified locations in the asset register such that the asset register defines records for all assets defined in the model files. Furthermore, given that each asset record has a predefined set of data fields associated with the relevant asset type, the asset register includes both values pre-populated via the BIM model file extraction process, and data fields that are to be completed during the construction phase, as discussed below.
As noted, in a preferred embodiment the set of data fields for a given asset type is determined by reference to a COBie specification for that asset type. By way of example, data fields may include those able to be populated directly from a BIM model based on the technology described above (and metadata assignment schema for assets in BIM model files), and additionally a plurality of fields to be completed during the construction phase. These optionally, include, by way of example:

- One or more data fields representative of a state of asset installation.
- One or more data fields representative of a state of asset commissioning.
- One or more data fields representative of a state of asset testing. For example, this may include, in the case of a HVAC component, air flow measurements and the like.
- A device network address (or other information allowing connection to the asset over a network). That is, for at least a subset of the asset types, the predefined set of data fields include a field that is designated to be populated with a data value that enables accessing of live asset data from a physical networked device that physically embodies a specific asset represented by a given asset record. This may include enables identification of the physical device on a BACnet network, and is optionally used to provide mapping of live asset data from a physical asset to a digital twin interface.

The data fields also include a global unique identifier (GUID). The GUID may defined by a software application used to generate the BIM model file (for example when defining assets in Revit, the software application inherently assigns a UID to each asset). In a preferred embodiment the GUID is a hybrid between an asset identifier defined by a software application used to generate the BIM model file and an asset name data value (which is preferably defined by reference to asset type and location). A data validation module is configured to validate that each asset has an asset register GUID that is unique in the asset register database.
System 100 includes an asset data input module 101 which is configured to provide access to the cloud-hosted asset register 110 that is populated with partially completed asset records (for example records partially completed based on operation of input module 106).
Asset data input module 101 is configured to enable a user of a remote client terminal (for example terminal 130A-130 n, which represent computing devices that download from a web server computer executable code thereby to enable rendering in a browser application a user interface with which to interact with system 100) to add data values to data fields for a subset of the records in the asset register. This subset is defined based on permissions maintained by the permissions management module, which define scope of responsibility for each user. For example, a user's permissions are tied to one or more asset field values including category, location, type and system. This allows for tailored scope of responsibility assignment. An example interface is illustrated in FIG. 3 . FIG. 3 provides an example user interface component rendering from an asset editor module 113 according to one embodiment, showing assets of type “Air Handling Unit” belonging to the category “Mechanical”.
FIG. 2B illustrates a method performed by the asset editor module 113.
Block 221 represents a user login process, which if completed successfully (i.e. the user provides credentials which are successfully validated) provides the user with access to user interface components that enable navigation (block 222) to an asset register display based on a desired asset category selection, and optionally one or more user-inputted filters. Block 223 represents a process including an asset register search, and causing display of asset data via the user interface based on the user's navigation (and optional filters), and additionally based on filtering performed based on the user's scope of responsibility based permissions.
Block 224 represents a process by which a user updates one or more asset records. This is able to be performed via the user interface, or in some embodiments via data export to a local file (e.g. a CSV file) which is edited on a local machine, and subsequently uploaded to import updates. Block 225 represents a data validation process by which module 113 interacts with an asset compliance rules module, which maintains a set of rules (i.e. data requirements) to be satisfied, thereby to determine whether the data is suitable for pushing to the asset register (block 226). Where issues are identified, the user is prompted to rectify those.
System 100 also provides functionality for monitoring asset installation for a building project based on level of asset data completion as reflected in the asset register. In this regard, a compliance rules module 103 is configured to maintain, for each asset type, one or more rules for determining a record completion compliance measure. This rules module operates in conjunction with a compliance monitoring module that is configured to, responsive to the rules module, determine and enable output of data representative of record completion compliance measures for the asset records in the asset register database.
FIG. 4 illustrates a dashboard that provides a user, for example a system administrator or head contractor, with data generated by the compliance monitoring module (for example via a web page interface), thereby to deliver situational awareness over progress in terms of assets being added to the asset register. In this diagram, the information displayed includes:

- Number of expected assets, based on BIM data.
- Number of compliant assets (i.e. assets added to the data register which satisfy the rules implemented by module 114).
- Number of non-compliant assets (i.e. assets added to the data register which fail to satisfy the rules implemented by module 114).

This allows for convenient visual tracking of progress in an asset upload process against key project milestones and the like.

Example Process Flow

FIG. 5 provides an example process flow according to one embodiment, which is at least in part implemented by the system of FIG. 1A.
Block 501 represents a process whereby multiple parties collaborate on a building design project, which results in generation of a plurality of individual BIM model files (e.g. Revit files) for the project. At block 502, the files are cross-validated and finalised (which includes verifying that assets defined in the files make use of a predefined metadata assignment schema).
Block 503 represents a data extraction process whereby each of the design collaborating parties operate a software plugin (for example an Autodesk Revit plugin) which is configured to cause extraction of asset data from the relevant Revit file and push that data to a server where it is applied to generate new asset records in an asset register database, pre-fill those records with data extracted from the Revit file, and create data fields additional for later completion based on a determined asset type (and/or based on other attributes), for example based on a COBie specification.
Block 504 represents an asset data completion phase, whereby during building construction a plurality of users gain access to update asset records in the asset register (via SOR-based permissions) thereby to complete other required data values. This includes physical installation, testing, commissioning and (where relevant) data mapping). Block 505 represents asset compliance monitoring, whereby the filling of asset data in the asset register is assessed against compliance rules.
Block 506 represents a digital twin connection process, whereby the asset register is used to create a mapping between graphical renderings for a building delivered via a digital twin interface to live data values (and optionally control interfaces) for networked assets, for example assets on a BACnet and/or other IOT devices. This mapping is achieved based on updating of the asset register to include data that provides access to live data (and/or control interfaces), and additionally in some embodiments based on a common GUI available to both the asset register and in digital twin model data. This is discussed in more detail further below.

Digital Twin Generation

FIG. 1B illustrates a configuration according to one embodiment, which supports generation and viewing of a digital twin interface for a building or other facility via components which operate at various phases of the building lifecycle. Components from FIG. 1A are illustrated using corresponding reference numerals. However, it will be appreciated that technology of FIG. 1B is in some embodiments applied using components other than those described by reference to FIG. 1A.
FIG. 1B depicts an asset register generation process which makes use of: (i) a data extraction process thereby to extract preliminary asset data values from BIM model data (e.g. Revit files), along with an asset GUID derived from those extracted asset data values; and (ii) an input process by which asset records are updated to populate data fields (for example COBie specification data fields) during construction. The latter includes, for at least a subset of asset records, inputting of data thereby to enable accessing of a live data feed and/or control interface for a physical networked device described by the asset record. For example, this may be a BACnet ID which allows for identification of the asset on a BACnet network.
BIM model files (e.g. file 123) generated by system 120A-n are also provided to one or more 3D visualisation generation systems, for example computer systems operating a computer program product such as AutoCad. Revit files are converted into an AutoCad format via these systems, and one or more users manipulate the software thereby to generate visualisation files for a digital twin interface. These files 161A-161 n are stored in a visualisation database 160. Each of these files includes locational markers associated with assets that are diagrammatically represented, these being marked using the same asset GUID used for the purposes of asset register 110.
A digital twin platform 172 is configured to make files in database 160 available to user terminals, such as an example user terminal 171, which executes a digital twin interface module 171. Digital twin interface module is configured to enable rendering and user-controlled 3D navigation of 3D visualisation modules generated by system 150 and stored in database 160, and allow display of asset data for assets that are rendered in a display window of the client terminal.
The display of asset data is facilitated by communications between digital twin platform 172 and asset register 110. In particular, by accessing asset register 110 and submitting a query containing a given asset GUID known from the visualisation data file, platform 172 is able to obtain data required to enable accessing of a live data feed and/or control interface (for example via a BACnet), and beacon that data cause the live data feed and/or a rendering of the control interface to be procured from a relevant physical device 173 and displayed at terminal 170.
This mapping of data visualisations to physical assets is also illustrated in FIG. 6 . A Revit file from building design is able to form a basis to commence two entirely separate processes: (i) population of an asset register for a physically constructed building with operational connected devices; and (ii) generation of visualisations for rendering in a digital twin interface. By way of the technology described herein, which uses a common asset GUID process as a basis for both of these discreet and separate processes, a digital twin interface is able to be functionally connected to live data and/or control interfaces from physical assets without need for a separate digital twin asset configuration process.
It will be appreciated that this approach to digital twin generation provides substantial technical advantages over prior art approaches, particularly in the sense that mapping of data between physical devices and the digital twin interfaces is essentially automated by virtue of a separate asset register generation and compliance process, which is of separate utility in the context of monitoring building completion progress.

Accordingly, it is to be understood that the invention is not to be limited by the specific illustrated embodiments, but only by the scope of the appended claims.
It should be appreciated that in the above description of exemplary embodiments of the invention, various features of the invention are sometimes grouped together in a single embodiment, FIG., or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of one or more of the various inventive aspects. This method of disclosure, however, is not to be interpreted as reflecting an intention that the claimed invention requires more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive aspects lie in less than all features of a single foregoing disclosed embodiment. Thus, the claims following the Detailed Description are hereby expressly incorporated into this Detailed Description, with each claim standing on its own as a separate embodiment of this invention.
Furthermore, while some embodiments described herein include some but not other features included in other embodiments, combinations of features of different embodiments are meant to be within the scope of the invention, and form different embodiments, as would be understood by those skilled in the art. For example, in the following claims, any of the claimed embodiments can be used in any combination.
Furthermore, some of the embodiments are described herein as a method or combination of elements of a method that can be implemented by a processor of a computer system or by other means of carrying out the function. Thus, a processor with the necessary instructions for carrying out such a method or element of a method forms a means for carrying out the method or element of a method. Furthermore, an element described herein of an apparatus embodiment is an example of a means for carrying out the function performed by the element for the purpose of carrying out the invention.
In the description provided herein, numerous specific details are set forth. However, it is understood that embodiments of the invention may be practiced without these specific details. In other instances, well-known methods, structures and techniques have not been shown in detail in order not to obscure an understanding of this description.
Similarly, it is to be noticed that the term coupled, when used in the claims, should not be interpreted as being limited to direct connections only. The terms “coupled” and “connected,” along with their derivatives, may be used. It should be understood that these terms are not intended as synonyms for each other. Thus, the scope of the expression a device A coupled to a device B should not be limited to devices or systems wherein an output of device A is directly connected to an input of device B. It means that there exists a path between an output of A and an input of B which may be a path including other devices or means. “Coupled” may mean that two or more elements are either in direct physical or electrical contact, or that two or more elements are not in direct contact with each other but yet still co-operate or interact with each other.
Thus, while there has been described what are believed to be the preferred embodiments of the invention, those skilled in the art will recognize that other and further modifications may be made thereto without departing from the spirit of the invention, and it is intended to claim all such changes and modifications as falling within the scope of the invention. For example, any formulas given above are merely representative of procedures that may be used.
