Linked Data Building: building fast and efficient connections

One of the most common “buzz words” associated with BIM (Building Information Modelling) has to be Linked Data Buildings. This might be one of the most useful and intuitive uses of  Building Information. Linked Data Building provides a way to structure data so that the user can clearly see the relationships between data points, which then allows them to ask questions like: “If I were to increase the window size by 10%, how much more cooling will be needed”. 


Linked Data Building will also promote the ease of collaboration and communication between different stakeholders. It allows the flow of information to be accurate and faster, stakeholders can easily access the information that is relevant to them. For example, designers can view room dimensions and edit them, with the total area calculated in real-time, the area can then be easily accessed by the clients or interior designers to suggest changes and concerns. This collaborative effort will reduce confusion due to communication errors, which in turn leads to a faster construction time, streamlining the whole construction project, not to mention edits and changes can be made quicker and with fewer complications. 

With Linked Data technology, all data point is only stored in one place, in which the stakeholders can access it via a link. This ensures all stakeholders have the same critical and essential information to work with. You can also restrict access to certain sensitive information, limiting the chances of unwanted data breaches, ensuring that only relevant information gets shared with the right people. 


An excellent application of this technology is the Danish engineering consultancy firm called NIRAS. They are working on a common knowledge model for building data. The main goal of this is to automate the work process involved in designing and dimensioning heating systems. There are also examples of open-sourced Linked Data Building, one of which called DPMedia, created as a collaborative effort between many internet users. They have created complex knowledge graphs and data sets in which the users can use to answer complex queries, such as: “identify a list of buildings that has a pool or uses the same type of toilet.” 


Although this technology is still under constant research and development, it has shown huge potential in many use cases, especially in the building and construction industry. Once this technology is widely applied, we will see a huge increase in productivity as all phases of construction will benefit from Linked Data Technology.
