Off-site construction (OSC) is an alternative method to conventional construction for solving problems of high energy consumption, high pollution, and poor efficiency. OSC is a reform trend for the global construction industry. The emergence of OSC can influence the production relations in traditional construction industry chain, thereby changing the roles of stakeholders in such new construction sector. Given that most developing countries at present are still in the initial stage of adopting OSC, their construction industry is far from forming healthy and symbiotic ecosystem and highly efficient industry chain. Therefore, the scientific and rapid development of OSC becomes restricted. This study analyzes the mechanism of OSC ecosystem, reduces the vague understanding of OSC by stakeholders, and provides a reference for the strategy planning of stakeholders. From the perspective of bionics, this study aims to (1) establish an OSC ecosystem based on the theory of ecology and delimit the role of stakeholders in the OSC ecosystem, and (2) establish a LotkaäóñVolterra model for the OSC evolution. The OSC development in Beijing is used as an example. Data are collected and models are verified to discuss the state, trend, and turning point of the OSC evolution. The findings of this study can help stakeholders in comprehensively understanding the inherent historical development of OSC and provide a reference for the government decision making.

The construction industry in Nigeria has continuously witnessed rapid development as a result of massive investments in infrastructural projects such as housing. The continuous growth of this industry and the conventional approach to construction practices in Nigeria have negatively affected the environment and the wellbeing of the populace. Therefore, the concept of green architecture, also known as sustainable architecture, is a new approach in Nigeria’s construction industry that strives to achieve environmental sustainability. However, various factors have hindered its adoption and utilisation. This study, therefore, examined the various factors hindering the use of green architecture through various literature reviewed and administered questionnaires to built environment professionals in Nigeria to ascertain their perception of those identified factors. Data gathered from the questionnaires were analysed using descriptive statistical tools and ranked according to each factor’s mean index score and relative importance index. The results of the study revealed the most prominent factors hindering the utilisation of green architecture in Nigeria. Hence, findings from this study suggest that more efforts such as public enlightenment and the provisions of incentives are needed to be done by the government, built environment professionals, and other stakeholders in Nigeria’s construction industry for the promotion of green architecture.

The world is entering a new phase of the digital era, including Indonesia. The unification of the real world and cyberspace is a sign, where the conditions of both can influence each other (Hyung Jun, 2018). The patterns of behavior and public relations in the virtual universe gave rise to new social interactions called the Digital Society. One part of Global Megatrends has also influenced public policy in Indonesia in recent years. Critical mass previously carried out conventionally is now a virtual movement. War of hashtags, petitions, and digital community comments are new tools and strategies for influencing policy. This paper attempts to analyze the extent of digital society's influence on public policy in Indonesia. As well as what public policy models are needed. Methodology used in this analysis is qualitative descriptive. Data collection through literature studies by critical mass digital recognition in Indonesia and trying to find a relationship between political participation through social media and democracy. By processing the pro and contra views regarding the selection of social media as a level of participation, this paper finds that there are overlapping interests that have the potential to distort the articulation of freedom of opinion and participation. - which is characteristic of a democratic state. The result is the rapid development of digital society which greatly influences the public policy process. Digital society imagines being able to participate formally in influencing policy in Indonesia. The democracy that developed in the digital society is cyberdemocracy. Public space in the digital world must be guaranteed security and its impact on the policies that will be determined. The recommendation given to the government is that a cyber data analyst is needed to oversee the issues that are developing in the digital world. Regulations related to the security of digital public spaces must be maximized.
