The aim of Technical Studies 3 is, first, to further develop the technical knowledge of architecture students, to provide them with a routine of the mathematical and physical concepts and basic knowledge that are essential for the study of the subject. Second, to familiarise them with the TOOLKIT of the technical disciplines, and third, to provide an extensive overview of the typical structures of more complex buildings, primarily with regard to their support structural and construction properties, but also continuously examining the support structural and construction aspects of other technical disciplines (e.g. static and dynamic loads, structural breakthroughs, fastening technology tasks...etc.). Becoming familiar 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 what extensive TOOLKIT the technical information, constituting a coherent whole from the correlations of the disciplines (primarily building engineering/HVAC systems in this semester), used together serve the physical (comfort), mental (peace) and spiritual (fulfilment) needs of building users. Laying the foundations for complex design. This is then taken a level higher in the third semester, i.e. the first semester of the ADVANCED course.
