Integrated asset management for lighting in public libraries through digital twins

New technology such as LED lights improved the performance of lightning installation. The next step is to go from corrective maintenance to preventive maintenance (from “replace when it breaks” to replacement before the lifetime of a component is reached).

The project intends to change the handling and management of lighting and lighting facilities in city libraries, all the way from planning to operation and finally optimization. Technical developments, such as LED lights, have resulted in a high performance of the lighting. The next challenge is to manage the total lighting installation more efficiently; to meet the increasing demands and complexity of lighting by combining the visual, biological, and emotional benefits of lighting.

Current lighting management practices still include corrective maintenance, "fix it when it breaks". However, most visual aspects (incl. intensity) and non-visual aspects (incl. light flicker) are rarely included in lighting management. The project takes its starting point from the need to change from corrective to predictive maintenance. The project intends to develop strategies, frameworks, and models for integrated management of lighting for city libraries through digital twins.
