Due to the signiﬁcant contribution of the built environment to all the sustainability dimensions, it has become a potential sector for achieving sustainable development. To facilitate sustainabilityintegration, a growing number of approaches have been developed. However, ambiguity and conﬂict in proposed approaches have raised concerns among academics and practitioners. Therefore, further research on the function of scientiﬁc sustainability frameworks and methodologies in the practice of the built environment sector is of value. The overall aim of this dissertation was to increase knowledge on the manifestation of sustainability in the operation of the built environment sector. To achieve this, ﬁrst the sustainability literature in the context of the built environment was reviewed to identify the existing approaches. Second, the perceptions and actions of two main actors (public and private) in the built environment sector were analysed using the existing or self-created frameworks. Third, the motivations that drive the actors' perceptions and actions were discussed. To address the research aim, a number of qualitative methods were combined. The empirical research involves three case studies in Finland, as well as literature review, content and discourse analysis of the secondary data. The ﬁndings show a large variety of approaches and frameworks to address sustainability. In addition, results reveal that perceptions and actions of private and public actors regarding sustainability are different. Moreover, legal requirements and ﬁnancial incentives found to be the main motivations for the actors. Based on the ﬁndings, this dissertation argues that private and public actors should be treated and evaluated differently. Developing context-speciﬁc approaches would better ﬁt the context and increase comparability. In addition, this dissertation suggests that integrating social sustainability into processes could legitimise the trade-off in the process that is caused by inherent conﬂicts between different actors and between the sustainability dimensions. Furthermore, the present dissertation claims that sustainability is nascent and evolves along with society; therefore, the focus should be on processes in which the change is stimulated. The academic value of this research is in the understanding it has developed on the complexrelationship between the built environment system and sustainability, which is essential forachieving progress in theory and practice. Moreover, this research helps academics to understandhow and why diverse actors perceive sustainability differently. This can improve the effectivenessand legitimacy of built environment sustainability strategies in practice. The empirical ﬁndingsbring new evidence to the stakeholders and help them in obtaining a holistic understanding ofsustainability and addressing the shortcomings identiﬁed in this research. This can in the longerterm advance the integration of sustainability in the built environment.
