Abstract:
In this paper, the economic benefits of adaptive building structures are demonstrated in comparison with conventional building structures. For this purpose, relevant types of use were delimited and the definition of a conventional building was developed. In addition, the costs of adaptive building structures were considered in three different adaptivity levels. For the quantity and cost calculation, the focus was on conversion measures in cost groups 300 and 400 according to DIN 276. The data basis for the cost calculation were key items for building elements, which were summarised from triangularly distributed averaged building price items from the SIRADOS building price database. In the course of the work, economic advantages of the adaptive building structures could be shown compared to the building structures defined as conventional. No economic advantage could be found between the adaptivity levels based on the degree of adaptivity. Particular cost effects resulted from the assumptions made regarding the façade constructions, as well as the location of the horizontal installation zones of the technical building equipment. It was demonstrated that in addition to ecological advantages of constructing adaptive building structures, there are also long-term economic advantages of economically favourable conversion measures and the avoidance of vacancies in the properties.
