    National Grid Electricity System Operator (ESO) has launched a world-first programme to build a digital replica of the entire GB energy landscape, creating a virtual environment to share data, model and predict scenarios that support the decarbonisation of the energy system. The Virtual Energy System will be a digital twin of the existing physical energy system, working in parallel to enable an accessible, unified, real-time view of every part of the GB energy system. This virtual environment will create the ability to generate insights and new ideas and model solutions to cut real-world carbon emissions, supporting the transition to net zero while delivering long-term value to industry and consumers. The programme comes at a time when Great Britain’s energy system is undergoing its most significant ever transition, and this announcement coincides with the annual COP26 UN climate change conference this year, taking place in Glasgow. How the Virtual Energy System will work: 1. The development of the Virtual Energy System begins with an open framework, with agreed access, operations and security protocols. 2. Over time, this will be populated by existing and new digital twins – replicas of physical components of the energy system. 3. Each digital twin will contribute to and access real-time data on the status and operation of other elements of the system. 4. This layered data will generate insight, and a virtual environment through which to innovate ideas, with the potential to transform the system and support the transition to net zero. National Grid ESO will be hosting a free-to-access one-day online conference on 1 December, providing an opportunity for the energy industry and wider stakeholders to find out more about the programme and how to get involved with its design and development. Panellists include Ofgem, BEIS, Energy Digitalisation Taskforce, Energy Systems Catapult and more. Interested parties can register for the conference here (https://uk.virtualeventhosts.com/virtualenergysystemconference2021/login) An industry consultation will be launched in December, and future industry events will be announced as the programme develops. Visit the Virtual Energy System webpage.

  2. A new infographic, enabled by the Construction Innovation Hub, is published today to bring to life a prototype digital twin of the Institute for Manufacturing (IfM) on the West Cambridge campus. Xiang Xie and Henry Fenby-Taylor discuss the infographic and lessons learned from the project. The research team for the West Cambridge Digital Twin project has developed a digital twin that allows various formats of building data to function interoperably, enabling better insights and optimisation for asset managers and better value per whole life Pound. The graphic centres the asset manager as a decision maker as a vital part of this process, and illustrates that each iteration improves the classification and refinement of the data. It also highlights challenges and areas for future development, showing that digital twin development is an ongoing journey, not finite destination. The process of drawing data from a variety of sources into a digital twin and transforming it into insights goes through an iterative cycle of: Sense/Ingest - use sensor arrays to collect data, or draw on pre-existing static data, e.g. a geometric model of the building Classify - label, aggregate, sort and describe data Refine - select what data is useful to the decision-maker at what times and filter it into an interface designed to provide insights Decide – use insights to weigh up options and decide on further actions Act/Optimise - feed changes and developments to the physical and digital twins to optimise both building performance and the effectiveness of the digital twin at supporting organisational goals. Buildings can draw data from static building models, quasi-dynamic building management systems and smart sensors, all with different data types, frequencies and formats. This means that a significant amount of time and resources are needed to manually search, query, verify and analyse building data that is scattered across different databases, and this process can lead to errors. The aim of the West Cambridge Digital Twin research facility project is to integrate data from these various sources and automate the classification and refinement for easier, more timely decision-making. In their case study, the team has created a digital twin based on a common data environment (CDE) that is able to integrate data from a variety of sources. The Industry Foundation Classes (IFC) schema is used to capture the building geometry information, categorising building zones and the components they contain. Meanwhile, a domain vocabulary and taxonomy describe how the components function together as a system to provide building services. The key to achieving this aim was understanding the need behind the building management processes already in place. This meant using the expertise and experience of the building manager to inform the design of a digital twin that was useful and usable within those processes. This points to digital twin development as a socio-technical project, involving culture change, collaboration and alignment with strategic aims, as well as technical problem solving. In the future, the team wants to develop twins that can enhance the environmental and economic performance of buildings. Further research is also needed to improve the automation at the Classify and Refine stages so they continue to get better at recognising what information is needed to achieve organisational goals. You can read more from the West Cambridge Digital Twin project by visiting their research profile. This research forms part of the Centre for Digital Built Britain’s (CDBB) work at the University of Cambridge. It was enabled by the Construction Innovation Hub, of which CDBB is a core partner, and funded by UK Research and Innovation (UKRI) through the Industrial Strategy Challenge Fund (ISCF).

    The Climate Resilience Demonstrator (CReDo) project from the National Digital Twin programme is holding a webinar to launch the project to a global audience in conjunction with the COP26 climate conference on 2nd November at 10:30-12. This webinar replaces the weekly Gemini Call, and the DT Hub community are encouraged to sign up, as well as inviting their wider networks to attend. The climate emergency is here now, and connected digital twins are an important part of achieving net zero and climate resilience. The CReDo team will present how the project meets this urgent need, and will premiere two exciting outputs – a short film and an interactive visualisation of how connected data across three infrastructure networks can provide better insights and lead to better resilience of the system-of-systems overall. Only if we come together to securely share data across sectors can we plan a smarter, greener, more resilient built environment. Book your spot today! Keep an eye on the DT Hub website for updates about the CReDo programme.

    Planning Golden Thread

    Click here for video As citizens and professionals we accept that the planning process is there to uphold standards of safety, aesthetic, technical and social requirements. However, the planning process has suffered from many years of tinkering and making good. We now have a planning process that is dependent on outdated approaches and incompatible with the rest of the development industry. It is slow, which presents problems in the UK where we need to build, a lot, quickly. Planning risks preventing this building from happening at pace and of a higher quality. This situation presents, of course, a golden opportunity for a fully digitised end-to-end process which could: reduce the planning bottleneck automate those parts of the process that can be Increase transparency of the process open up new means of engaging stakeholders with the planning process, by for example visualising proposed developments and so increasing understanding allow us to see projects in context, with other proposed developments, rather than in isolation allow access to, and sharing of, crucial data (like structural and fire safety information) facilitate the use of modern methods of construction most importantly, give a more accurate understanding of build costs and timescales In order to bring this about, we have to standardise and digitise (as far as it is possible and desirable) the rules under which designs are created, assessed, and ultimately built. At the same time we have to find ways to generate and use interoperable data. This problem is what the group from Bryden Wood, 3D Repo, London Borough of Southwark and CDBB have been working on. We have developed a model which is open and based on the established BIM Collaboration Framework (BCF). It presents the data associated with planning so that it can be queried and interrogated. You can see a summary in the video above and read more about it here; Planning Golden Thread statement attached below 3DRepo technical write up Bryden Wood technical write up Bryden Wood Schema We know that many of the barriers associated with a change like this will be cultural rather than technical so we are seeking partners in the planning and development system who would like to test the model and collaborators who would like to fund the next stage of development. Please get in touch! You can also hear more about this on the Gemini Call on Tuesday, 18 May at 10:30 with Miranda Sharp and Jack Ricketts of Southwark Council. Link to DT Hub Calendar

    Test Engineering and DTs

    I am considering starting a network for topics related to Lifecycle V&V (Validation and Verification) centred on Evaluation and Testing, and this message is to poll the level of potential interest. I imagine the network would offer the following: · A place for Test Engineers from different market sectors to share experiences and gain knowledge · Support for those areas where DT activity is low but growing, the Defence Sector is an example, to benefit from the experiences of other sectors Test Engineers have a mix of technical and customer skills that are central to successful project implementation. The DT concept provides a lifecycle project-thread that provides Test Engineers with an unprecedented opportunity to exercise their skills. Maybe finding a way to maximise this opportunity might also attract more people to the career, and be a way to improve recruitment into the world of Engineering? If we launch this Network, would you consider joining it? Dave Murray

    Infrastructure projects inevitably cause impacts to our environment. The pressure is therefore on contractors to adhere to new policies using their own initiatives and tools. In addition to adhering to new net gains policies that will be released with the upcoming environment bill, other impacts of not considering our environment include project delays and increases in costs, and damage to a contractors social and sustainable reputation. Integrating GIS to current environmental planning methodologies improves on existing tools for evaluating and quantifying biodiversity and Natural Capital. By doing this we can visualise the areas that would potentially have the highest loss, and adapt the design to mitigate impacts and reduce those losses.

    Projects that are planned well are safer. Methods like 4D modelling improve construction planning, bring teams together, and provide a visual output that can be used in RAMS and site inductions. By planning sequences in detail, modelling logistics and access, and constructing virtually in advance, hazards can be identified, managed or avoided. Through the session and panel, we'll delve into what 4D modelling means to us, outline the Health and Safety benefits, its contribution to DfMA, productivity improvement, improved planning, and describe in some detail how 4D can be used to get these benefits.

  14. Autonomous vehicles require digital maps to navigate safely, smart cities requires knowledge of urban features to be managed appropriately, and digital twins require physical assets to be recognised before they can simulate predictive models. All those applications require a detailed representation and understanding of the spatial environment. The ability to create intelligent 3D models of the real world is a critical enabler for the reduction in cost and programme of major design activities. For instance, Highways England is one of the pioneers in developing parametric design solutions for complex national infrastructure. Working together with the Alan Turing Institute and the University of Oxford, Sensat opened up some of our data to look at collaborating and building on the last two years of working at the cutting edge of 3D computer vision as part of our mission to teach computers to understand the real world. Great read if you have some time and as we continue to explore creating full digital models of existing assets - advancements in AI and data segmentation will allow us to truly create replicable models of real infrastructure, cities, and more. https://www.turing.ac.uk/sites/default/files/2020-06/the_alan_turing_institute_data_study_group_final_report_-_sensat_0.pdf the_alan_turing_institute_data_study_group_final_report_(Sensat).pdf
  15. https://www.youtube.com/watch?v=ZyIwEwEfqFA Interesting application regarding the monitoring of people movements for supporting coronavirus management at St Pancras station in real-time. Interesting to hear viewpoints regarding whether or not we fully recognise this as a Digital Twin in not.
  16. One of the things that we discovered here at Highways England shortly after starting work on our Ontology (see previous post) was that there isn't a huge provision of COTS tools to help you visualise your Ontology, and consequently human readability suffers once you move past a few dozen entities and relationships. Moreover, a key Ontology-building tool (WebProtege) isn't really a commercial offering at all, and as such will probably never be Enterprise-ready (and indeed could go down at any moment!). Other tools such as WebVOWL seem to have paused at the 'nice idea' stage of development, and in general the real development in the market appears to be in the graph database space (Neo4j, Grakn, Stardog) rather than the Ontology-building space. There certainly isn't, as I had hoped, a fully configured GUI where you can filter and dynamically edit your Ontology as you would a mind map without having to resort to form-filling. If we want our Ontology to function as a schema for a graph database, and that graph database in turn to provide the data storage and logical underpinning of the Digital Twin (and the interface between twins) then limitation to the visualisation and management of our Ontology will consequently limit the functionality and acuity of our Digital Twin. Key to making this logic work is being able to clearly visualise and edit Ontologies because that will in turn dictate the relationships that it’s possible to model in the Twin. There isn’t really a COTS product that fully fits this brief at the moment, but we have undertaken some research (attached) to assess the market and identify where some investment in products could fill this gap (and indeed wrote some code to make our current tool of choice, Web Protégé, work slightly better). It would make sense to me that if we are seeking alignment in how we create and interface Ontologies, then it makes sense that we also work towards a common toolkit for their creation, maintenance, and visualisation. The attached PowerPoint describes our market evaluation to date, including where we feel that there is opportunity to augment WebProtege, as well as the obvious opportunity posed by Neo4j Bloom. It seems to me that if we, as a sector, are investing in the creation of Digital Twins, then we should think about how we can work together to build capability in the market to make these tasks easier and more scalable. A common toolkit will reduce our individual investments, whilst maximising the value that we obtain from development. What do you think? Ontology_Visualisation_Proof_of_Value_(HE).pdf

    45 minute Cities

    Hi all, Alasdair Rae of University of Sheffield has published a blog piece about travel within 26 cities using open data to visualize how far can you travel from to reach a central train station by 08:45 on a Monday morning. http://www.statsmapsnpix.com/2020/03/45-minute-cities.html The ability to produce this visualization seems very relevant to the NDT programme. Particularly if you could simulate traffic interventions to see how it improved access across the city. Cardiff has fared quite well. How has your city performed?
