The European Union (EU) is striving to achieve its goal of being climate-neutral by 2050. Aligned with the European Green Deal and in search of means to decarbonize its urban environments, the EU advocates for smart positive energy districts (PEDs). PEDs contribute to the United Nations’ (UN) sustainable development goals (SDGs) of “Sustainable Cities and Communities”, “Affordable and Clean Energy”, and “Climate Action”. PEDs are urban neighborhoods that generate renewable energy to a higher extent than they consume, mainly through the utilization of innovative technologies and renewable energy sources. In accordance with the EU 2050 aim, the PED concept is attracting growing research interest. PEDs can transform existing energy systems and aid in achieving carbon neutrality and sustainable urban development. PED is a novel concept and its implementation is challenging. This study aims to present the emerging technologies enabling the proliferation of PEDs by identifying the main challenges and potential solutions to effective adoption and implementation of PEDs. This paper examines the importance and utilization of cyber-physical systems (CPSs), digital twins (DTs), artificial intelligence (AI), the Internet of Things (IoT), edge computing, and blockchain technologies, which are all fundamental to the creation of PEDs for enhancing energy efficiency, sustainable energy, and user engagement. These systems combine physical infrastructure with digital technologies to create intelligent and autonomous systems to optimize energy production, distribution, and consumption, thus positively contributing to achieving smart and sustainable development.

Energy transitions concentrated on a neighborhood or district scale represent a fairly new area of focus at the European (EU) level, aiming to combat future global warming and to reduce anthropogenic greenhouse gas (GHG) emissions. In the EU energy transition policy agenda, positive energy districts (PEDs) refer to urban areas where more renewable/zero-emissions energy is produced annually than is consumed. PEDs have increasingly grown in recognition and significance, as a societal solution geared towards a low-carbon future. The relevant aims include the utilization of 100 PEDs by 2025 and alignment with the EU, which seeks to become a climate-neutral continent by 2050. However, this target raises questions regarding the means of achieving fast and consistent adoption across various socio-technical contexts. Defining the opportunities, challenges, and key issues to address short-term project timelines is vital to implementing fit-for-purpose solutions and bringing PEDs into the mainstream. Proactive knowledge sharing, adaptive learning, and collaboration across disciplines and sectors will bring know-how for understanding the requirements in different contexts. The need for practical approaches to facilitate PED implementation is crucial. This study aims to elucidate the opportunities for and barriers to successful PED design and implementation by compiling and synthesizing experiences from 61 PED projects, identifying key drivers, challenges, enablers, and ethical considerations. In addition, the authors present a framework, consisting of moral principles, which can help present the issues concerning the development and deployment of PED in an ethical context.

The aim of this study is to examine existing positive energy district (PED) initiatives by using an explanatory research approach for gaining insight, identifying patterns, clarifying underlying processes, exploring cause-and-effect relationships, and explaining phenomena in a greater depth. Specifically, studies from the existing literature that have explored multiple PEDs were analyzed. Current challenges, barriers, and obstacles, as well as success factors, good practices, and policy guidelines are thoroughly investigated, evaluated, categorized and compared to unveil lessons learnt from diverse existing international projects for turning urban areas into self-sustainable and greener urban neighborhoods. The proposed framework aims to reveal the required processes for successful PED creation and operation. It provides an overview of the current state of the art and enhances comprehension and know-how about the processes needed for the successful adoption and integration of PEDs based on lessons learnt from global challenges and success stories.

In today's competitive business environment increasingly large numbers of organisations use distributed teams in their international operations. This paper provides a basis for discussion and analysis of knowledge sharing between distributed team members working in a global context in different organisational and national cultures. Examining the different cultural values and perceptions related to knowledge sharing, the authors aim at making more explicit the human and cultural dynamics that bear on knowledge sharing and knowledge management success. A lifecycle for knowledge creation and sharing is discussed. The use of Cultural and Organisational Diversity Evaluation (CODE) is proposed for assessing the fit between national and organisational culture. The objective of using the CODE model is to raise awareness of the cultural values and attitudes in distributed teams and in combination with the life-cycle to ensure an effective process quality management and foster a knowledge sharing culture within distributed team members.
