The aim of Technical Studies 4 is, first, to further develop the technical knowledge of architecture students, to supplement their knowledge with special calculation procedures in the fields of building physics and building engineering. Second, to give them practice in the USE OF THE TOOLKIT of technical disciplines, and third, to provide an extensive overview of the typical structures of more complex buildings, with regard to their support structural and construction properties (e.g. architectural placement and operation, maintenance space requirements, window/door dimensions, minimum headroom requirements, special building structures such as e.g. pressure discharge surfaces, etc.). Completing familiarisation with the elements of the building engineering/HVAC system and the spaces needed for mechanical engineering - machine rooms, shafts. Continuing the main arc of thought behind the four areas of technical knowledge in the BA training period to determine how the technical information, constituting a coherent whole from the correlations of the disciplines, together uses their TOOLKIT to serve the physical (comfort), mental (peace) and spiritual (fulfilment) needs of the users of the building. Laying the foundations for complex design by the end of the semester (year). The student should recognise the extent of the necessity for electrical installation in each building type, and be aware of the technical requirements thereof in terms of magnitude.This is then taken a level higher in the forth semester, i.e. the second semester of the ADVANCED course.
