Digital twin of Löfstad Castle for energy efficiency

Purpose and goal:

We have reached the goal and fulfilled the three specified objectives: (1) installed cloud-linked devices with total 84 sensors for data acquisition in different locations within Löfstad Castle, (2) created a digital twin of Löfstad Castle for the purpose of energy efficiency, and (3) identified a heating strategy for energy saving of about 30% based on the feedback from the created digital twin of the castle.

Expected results and effects:

This project has been a collaboration between the two partners to make a case study on digitalization of Löfstad Castle through creation and demonstration of a digital twin for effective use of electricity in this monumental building. A digital twin of Löfstad Castle has successfully been created for both monitoring and control purposes, and a heating strategy to reduce electricity use has been worked out. About 30% energy saving can be achieved with a new heating system that will be installed in 2024.

Approach and implementation: The following activities have been carried out. Activity #1: 13 Smart Sensor Boxes with total 84 sensors have been developed and installed in Löfstad Castle. Activity #2: Functional digital twin of Löfstad Castle has been created and up-running.

Activity #3: Both monitoring and control functions with the created digital twin to reduce electricity use have been worked out. Activity #4: A new heating system has been planned to install in 2024.
