If walls could talk
The old expression has actually become a reality in the new office building A Working Lab (AWL) at Johanneberg Science Park. A digital twin of the building has been created and with the help of augmented reality (AR), you can look behind the walls of the house and see structures such as pipes and power lines. But the technology enables much more than that.
BIM (Building Information Model) has become increasingly common and means that in parallel with the construction of a building, a virtual model is created that contains information about the building. A digital twin is a further development of the concept which means that the model is connected through IoT. Thus, it is more accessible, and it can display data in real time. Via sensors in a building, you can for example see flows of ventilation air currents or the number of people present in the building.
The pilot has been developed within the EU project IRIS Smart Cities in collaboration with the company ReSpace and during a demonstration in September 2020, curious participants got to try out the digital twin in Augmented Reality (AR) via an app in their own mobile phones, but also see how it can be experienced in Virtual Reality (VR) using VR glasses.
— We have strived to make the digital twin as similar to reality as possible by adding colors, structures and furniture to the raw data that is in a BIM, says Anders Logg, CEO and founder of ReSpace.
In addition to seeing what is hidden behind the walls, the digital twin can, for example, be used to post comments and messages about things that need to be fixed in the building or as a visitor guide for those who want to know more about the house. It is only the imagination that sets limits and during the demonstration workshop generated many ideas such as competitions for those who work in the house, study visits and digital tours for potential tenants, visualization of energy production and consumption and a tool for Covid-19 prevention that shows how many people are in the building at a specific time so that crowds can be avoided.
— It is very exciting to be at the forefront of something that opens up for so many different areas of use. Within IRIS Smart Cities, we develop innovative solutions in order to share with our partner cities around Europe and this is something that there is a great interest in now, says Eva Pavic, project manager for IRIS Gothenburg at Johanneberg Science Park.
