The eDigit2Life Digital Twin creates a virtual representation of the real building at any point in time, using data from sensors and meters in the building. It uses physics intelligence, AI and Machine Learning to assure the accuracy of the model. IES has proven that the performance of the Digital Twin can be as good as 2% deviation from the actual buildings performance.
Important collaborations across teams and services within the University was key to the success of this project.
Despite the University being the owner of the buildings and having a dedicated energy manager, access to the data within the BMS was not always easy on this project, and new systems that were advertised as being open protocol or open access were not as easy to connect to as anticipated.
The project team therefore had to develop good interactions and communications with the IT department and sub-contractors to explain what the University was trying to achieve and why it should be a priority among all of the other ongoing priorities across the campus.
The power of the eDigit2Life Digital Twin is that it is updated right through to the operation phase of the building and is then used for Measurement and Verification and Monitoring and Targeting, once the building is occupied. In this way, the energy manager can ensure that the building is meeting its design objectives with respect to carbon emissions and where deviations occur, corrective actions can be taken immediately.
Many buildings do not perform as per their design (some are known to have 3-4 times higher emissions than estimated). This performance gap can be a large contributor to overall carbon emission reductions of our built environment. eDigit2Life ensures that the building performs as it should and that carbon emissions are minimised. This ensures that we achieve a gold standard built environment in reality and not just on paper.
90% or our time is spent indoors. 96% of Generation Y employees are concerned about the environment and expect their employers to take steps towards becoming more sustainable. Employees in green-certified buildings showed 26% higher cognitive function test scores and 30% fewer sick building symptoms versus non-certified. As such, through optimisation of energy and IEQ, better health and well-being of the building occupants can be assured, this leads to improved productivity of staff, less sick days, higher levels of concentration from students etc.
