Presentation of StepUP-research paper at the eSIM Conference

Presentation of StepUP-research paper during the eSIM Conference

Adalberto Guerra Cabrera, Senior Researcher & Consultant at the Integrated Environmental Solutions Limited (IES LTD), has presented the paper Optimised IES-VE model calibration methodology integrating IoT, smart meter and BMS data during the session “Simulation in Practice” held within the eSIM Building Simulation Meets Building Data Conference in the 14th of June 2021.

The paper, which results are part of StepUP project, introduces an iterative calibration methodology aligned with the latest calibration guidelines and IES’ best calibration practices. The goal is to integrate the information captured by BMS, IoT, smart metered data and ML predictions into the physics-based model following a “best of the two worlds” philosophy, in line with the core principles of the StepUP methodology. The process involves the use of state-of-the-art sensitivity analysis and optimisation-based parameter fine-tuning. The presented case study is an office building in Glasgow that is also the virtual pilot for the StepUP project.

The presentation was very well received, and attendees in particular appreciated the novel use of automation tools for the IES-VE software. The progress made in the last two years through research supported by the StepUP project enables the energy modeller to automate trial-and-error iterations that would take hours or days to do manually. Hence, we believe that this workflow is a substantial improvement of the process to create accurate digital twins of existing buildings. This is a key starting point to reliably achieve decarbonisation in renovation, the ultimate goal of the StepUP project.
