This book provides a detailed overview of the microorganisms that form the initial growth on the exterior façades of buildings. It deals with the ecophysiological properties that characterize the basic conditions under which these microorganisms can occur on façades. In addition to an identification key for the types and forms of microorganisms, this book provides a detailed description of the individual organisms, stating their ecological range. Furthermore, the various ecological parameters are discussed in short chapters. Measures to prevent and combat the colonization of façades with microorganisms are also addressed.

Specialists (architects, construction experts), builders, scientists and master students can find all the information they need on facade algae and fungi here.

Offers a unique overview of microorganisms on façades Contains an identification key for easy identification of the species Illustrates the contents with numerous figures Treats the ecophysiology of microorganisms in detail Describes measures for prevention and control of colonization of façades

Autorentext

Dr. Wolfgang Karl Hofbauer is chief scientist (taxonomy, ecophysiology and genetics) of the department Environment, Sensors and Hygiene at the Fraunhofer Institute for Building Physics. His professional research areas are taxonomy and ecophysiology of organisms on building surfaces, about which he did his doctorate in 2008, genetic barcoding of building relevant (micro)organisms and greening of building surfaces.

Retired Prof. Dr. Dr.h.c Georg Gärtner worked and researched at the University of Innsbruck on the cultivation and taxonomy of soil-and airborne. algae for many years. In 2012, Prof. Gärtner was awarded an honorary doctorate by Sofia University for his services to the cooperation in algal studies between the botanical institutes of the University of Innsbruck and the University of Sofia.
