This book is dedicated to all those who love children and their wonderful, often surprising, drawings. This means it addresses all those interested in their devel oping capacity to produce "iconic" signs: parents, teachers, child psychologists, artists, architects (since building drawings are treated here), and semioticians at large-to name but a few potential readers. Because of the broad audience, I tried to keep scientific jargon to a minimum. Whenever this was unavoidable, I tried to explain the terms in such a way that even beginners in psychology could understand my arguments. I received the first impulse to think about a book like this from the Interna tional Year of the Child declared by the UN in 1979. In a first phase of the project, I obtained drawings of the six different building types treated in this book from more than 100 children aged 3-12 years in Turkey during a stay there as part of the faculty of Architecture of the Karadeniz Technical University in Trabzon under the auspices of the UN ESCO/UNDP program TUR/75/012. My special thanks go to Dr. Erdem Aksoy, then president of the university, and Dr. Ozgontil Aksoy, then dean of the faculty of Architecture and Civil Engineering, for their encouragement to carry out the project. I would also like to thank Dr. Kutzal Oztlirk, Sevinc Erttirk, Ali Ozbilen, Hasan Saltik, together with all the teachers in nursery and elementary schools in and around Trabzon who helped to collect the drawings."

This book is designed to usher the reader into the realm of semiotic studies. It analyzes the most important approaches to semiotics as they have developed over the last hundred years out of philosophy, linguistics, psychology, and biology. As a science of sign processes, semiotics investigates all types of com munication and information exchange among human beings, animals, plants, internal systems of organisms, and machines. Thus it encompasses most of the subject areas of the arts and the social sciences, as well as those of biology and medicine. Semiotic inquiry into the conditions, functions, and structures of sign processes is older than anyone scientific discipline. As a result, it is able to make the underlying unity of these disciplines apparent once again without impairing their function as specializations. Semiotics is, above all, research into the theoretical foundations of sign oriented disciplines: that is, it is General Semiotics. Under the name of Zei chenlehre, it has been pursued in the German-speaking countries since the age of the Enlightenment. During the nineteenth century, the systematic inquiry into the functioning of signs was superseded by historical investigations into the origins of signs. This opposition was overcome in the first half of the twentieth century by American Semiotic as well as by various directions of European structuralism working in the tradition of Semiology. Present-day General Semiot ics builds on all these developments."

Air pollution resulting from high energy consumption is a major factor threatening our environment. Heating buildings accounts for about 40 per cent of Germany's total energy consumption.Current heat-insulation regulations for buildings aimed at reducing energy consumption have become considerably more stringent. However, greater heat insulation and energy saving necessarily restrict the exchange of air between outside and inside the building. This means that air quality in the building deteriorates and CO(2) and other pollutant contents increase.

For this reason, when planning the district headquarters for the Berufsgenossenschaft Gesundheitsdienst und Wohlfahrtspflege (Professional Association for Health and Welfare) in Dresden the aim was to produce an economical, environment-friendly building with a high proportion of solar heating and workplaces designed ergonomically and with an eye to health requirements.

The main architectural features of the building are a glass wall running the full length of the south side, large glazed areas on the east and west sides and solid walls enclosing the building on the east, west and north sides. The curved roof opens to the south, thus establishing the building's relation to the sun. The building is conceived in such a way that the solar energy is used first and foremost passively via the building's outer sheath. Special glass converts light into warmth even when light radiation is diffuse. In this way solar energy meets 50 per cent of the building's total energy needs.

The atmosphere inside the building is determined mainly by the subtropical plants used to improve and condition the air. This creates interesting, pleasant workplaces that make a different impression as the seasons change. The offices are divided up by shelf units, which makes it possible to adapt flexibly to changing needs.
