"As to common opinion the present state of the lecture halls at the Vienna University of Technology does not live up to the requirements of a present-day teaching atmosphere. Thus, a design program was developed for architecture students aimed at adaptation, conversion and add-ons regarding the exiting building substance in terms of improvements concerning teaching purposes at the university level. The main issue was to determine what performance could be expected from future lecture halls. New formulations and reinterpretations of the topic "lecture" as well as of the discussion forum including considerations regarding infrastructure and in particular referring to multimedia implementations were to be devised. As to capacity only lecture halls for no more than 100 _250 persons were to be dealt with. The approach was not to be regarded as a mere face-lifting, but to focus on the paradoxical relation between "old" and "new". Simultaneously, a practical evaluation of succesful and less succesful species of lecture halls at the Vienna University of Technology was carried out based on (self-) observation within the framework of the lecture course Environmental Psychology furnishing the empirical input of the planning process to this design program. The user perspective was of major importance throughout the evaluation, the actual main users, i.e. the students, being actively involved in the planning process of the lecture hall. Learning to use the set of tools of environmental psychology can be regarded as meaningful for future architects. Due to the social developments throughout the period of life devoted to "studying "calling for innovative forms, maximum user friendliness of the built environment "lecture halls" is of utmost importance."
