# Nyköping Hospital Uses Drones for Facade Cleaning A specialized drone replaces traditional scaffolding to remove lichen from hospital walls. - **Source:** [SVT Nyheter](https://www.svt.se/nyheter) - **Published:** 2026-11-12 - **Topic:** [technology](https://brifing.si/c/technology) - **Original article:** - **On Brifing:** https://brifing.si/s/09f169e7-7367-4c04-b555-f3e6d20ab63a ## Innovative Facade Maintenance Nyköping Hospital is addressing the accumulation of lichen on its high-rise facade using a specialized drone. This project, initiated by Region Sörmland, replaces manual cleaning methods that previously required extensive setup. The drone technology allows for precise application of cleaning agents on exterior surfaces that were once difficult to reach. ## Collaboration with Local Experts The initiative began when Region Sörmland contacted Martin Ulvenhag, a local construction firm owner in Nyköping. Together, they developed and tested a specific methodology for aerial facade treatment. This partnership highlights how regional authorities can leverage local small business expertise to solve unique infrastructure maintenance challenges through modern technical solutions. ## Worker Safety Improvements A primary driver for adopting this drone-based approach is the significant improvement in workplace safety. By eliminating the need for traditional scaffolding, workers are no longer required to operate at dangerous heights. This shift reduces the physical risks associated with facade maintenance while ensuring the building remains clean and structurally sound. ## Efficiency and Time Management Beyond safety, the drone method offers substantial time efficiency compared to conventional cleaning techniques. The highest section of the main hospital building is estimated to require only two working days for complete treatment. This rapid turnaround minimizes disruption to hospital operations and allows for more frequent maintenance cycles on large structures. ## Technological Operational Mechanism The drone is custom-built to carry and spray cleaning agents directly onto the building's exterior. This precision application ensures that the lichen is targeted effectively without causing damage to the facade materials. The system represents a practical application of aerial robotics in the maintenance of large-scale public and commercial healthcare infrastructure. ## Context of Building Maintenance Lichen growth on hospital facades is a common issue in Nordic climates, often affecting both aesthetics and material longevity. Traditional removal methods are labor-intensive and costly due to the logistics of scaffolding. Integrating drones into this workflow provides a scalable solution for property managers tasked with maintaining aging institutional building envelopes. ## Future Implications for Facilities The success of the Nyköping project may influence how other regional facilities manage their exterior maintenance. As drone technology becomes more accessible, the shift toward remote-operated cleaning could become standard practice for hospitals and high-rise buildings. This transition reduces overhead costs and improves the overall lifecycle management of public assets. ## Standardizing Aerial Maintenance While this specific project focuses on Nyköping Hospital, the methodology serves as a case study for non-invasive building care. Future developments may include automated flight paths or sensor-based cleaning to further enhance precision. The project demonstrates that simple, targeted technological interventions can solve long-standing maintenance problems in complex healthcare facility environments. ## Sources covering this story - https://www.svt.se/nyheter/lokalt/sormland/har-tvattas-nykopings-lasarett-rent-med-hjalp-av-en-dronare — --- _Summary written by Brifing from the original reporting.
