Increasing indoor air quality is a declared goal of the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV). In this research project, the project team for the Federal Environment Agency (UBA) determines the status of ventilation technology and ventilation options in public buildings through surveys and asks room users about ventilation behavior and the level of knowledge and awareness regarding indoor air quality and ventilation.
