The lifecycle concept in real estate management is of increasing relevance to owners and users. Especially through public procurement routes such as Public Private Partnerships lifecycle management gets into the focus during project development. But there is also an uncertainty about the efficiency gains through lifecycle management. The aim of this paper is to compare different lifecycle concepts in research literature and to analyse the perception of lifecycle concepts, strategies and instruments in public real estate management. For this investigation a written questionnaire was sent out via email to over 1000 interviews. The target group comprised real estate mangers from cities and districts as well as on federal level from universities and public real estate companies . The results of the study show that awareness of life cycle management is generally present amongst public real estate owners and managers. Although most of the lifecycle management instruments are well known, they are rarely applied in practice. Conclusions of this paper show where the lifecycle concept in real estate management is appropriate and how more value for the different stakeholders by applying lifecycle management can be retrieved.
