The Science Visualization Lab at the University of Applied Arts in Vienna specializes in blending scientific visualization with artistic expression to create accessible and emotionally resonant messages about environmental sustainability. By combining methods such as documentary filmmaking, art–science installations, collaborative research, and efficient computing, the lab addresses complex ecological challenges in creative and impactful ways. This contribution focuses on art–science installations as a method for educational and advocacy contexts. It provides a practical guide to using this method, detailing the steps, tools, and considerations necessary for readers to apply it effectively in their own settings. Please keep in mind that this is only one method of many, applied in the Science Visualization Lab of the University of Applied Arts Vienna, since limited space does not allow to describe all the methods, also the methods and approaches are constantly adapted to contemporary circumstances.
