Regenerative sustainability is gaining great attention as an essential concept for a transformative process, a re-designed mindset shifting from the narrowed focus of considering particular aspects such as energy efficiency, renewable materials, or sustainable technology towards the creation of a self-regenerating social and ecological system. Apart from being a vision of the future, regenerative sustainability has already been implemented successfully in individual projects, plans, and extensive strategies. The goals of this research are (1) to set up the conceptual framework for regenerative sustainability principles in the built environment; (2) to investigate and identify the drivers and barriers faced during the implementation of regenerative principles in the built environment; and (3) to identify gaps in the paradigm shift towards regenerative districts and macro-level projects. A multi-stage methodology was implemented. First, an in-depth literature review was conducted aiming to understand regenerative sustainability state of the art and define the key principles. Then, quantitative data analysis was conducted aiming to identify drivers and barriers of regenerative implementation in buildings following by semi-structured interviews with the representatives of regenerative buildings or districts. The step-by-step methodology resulted in the identified drivers of applying the regenerative principles, which are available financial incentives; marketing and sales benefits; improved companies/investors market image and competitive market advantage; reduced building lifecycle costs/effective use of energy and resources; enhancement buildings’ users’ well-being; and receiving building certification. The main barriers identified were lack of knowledge and experience working with regenerative materials and technologies by employees, consultants, and construction companies and usage of the available tools that enable such constructions; overall stakeholders’ culture and their resistance to changing their mindset toward a regenerative approach; inadequacy of national and international standards and legislation to address regenerative policies; and increased construction cost and time and lack of financial incentives. Ultimately, during the broad examination of the case studies, regenerative qualities served as a valuable insight to understand barriers and drivers at neighborhood and macro levels.

The vivid non-linear business environment of nowadays, enhances companies to embrace the complexity leadership approach, in order to remain competitive in a globalized industry. Maintaining their adaptive system is found to be the main challenge. This paper aims to analyze the up-to-date literature based on Complex Adaptive Leadership approach, focusing on Chaos Theory and Complexity Science. In addition a real-life case of a German company investing in real-estate sector in Albania is introduced. The highly dynamic environment of construction project depends on the information flow and interaction between project stakeholders, which is proved to impose high unpredictability, continuous disequilibrium and emergence. Butterfly Effect, Strange Attractors, Self-Organization, Emergence Decision-Making, Feedback and over all Complex Behaviors of the Company Leadership are discussed considering the circumstances under which the company has terminated the agreement with General Contractor during the construction phase. Finally the consequences of these changes are disclosed and recommendations for improving future actions are proposed.
