Project manager competency is a key factor determining the success of a project. With the deterioration of the environment, green buildings have come into being. Compared to traditional buildings, green buildings encounter more complex problems during the construction process, and project managers are faced with greater challenges. Existing research on the evaluation of project manager competency based on green building construction (GBC) is scarce. Thus, the aim of this paper is to evaluate project manager competency for green construction. By means of a literature review and a focus group meeting, the key success factors of green buildings and project manager competency were determined. Thereafter, a questionnaire survey was used to investigate people’s understanding of the importance of project manager skills. Structural equation modeling was selected to test the hypotheses. The results demonstrate that China is in the infancy of GBC development. Leadership and organization, target management, and emotional intelligence of project managers are considered to be important factors that affect green construction performance. The results of this study provide a theoretical basis for the selection of excellent project managers for GBC.

The trend of China’s construction industry has gradually shifted from traditional high-consumption to efficient green development mode to achieve the new goals of energy conservation, emission reduction, and sustainable development. The successful development of green housing (GH) has become a major strategic choice. Given the smooth implementation and delivery of GH projects, this study aimed to assess the impact of critical success factors (CSFs) on GH development by identifying controllable CSFs. Firstly, 20 controllable CSFs were identified through literature review. Secondly, the data collected by the questionnaire were used for principal component analysis (PCA). The factor analysis showed that the CSFs can be summarised into five important principal components, namely, (1) project management factors, (2) personnel ability factors, (3) teamwork-oriented factors, (4) human resource factors, and (5) financial and constraint factors. Finally, multiple regression analysis was used to assess the importance of CSFs. Results showed that project management factors, personnel capacity factors, and financial and constraint factors exerted positive impact on the successful development of the projects, with project management factors having the greatest impact. This work provides not only useful information and practical guidance for enterprises in GH development practice but also certain reference value for building a sustainable development society in China.

As the main spatial carrier for people’s social activities, street space occupies an important position in the urban space. However, under the direction of traffic-driven urban planning, the social function of street space has been neglected, resulting in the gradual loss of vitality. In mountainous cities with rugged terrain, the factors influencing the vitality of streets may be different compared to those in plain areas. In order to explore the influence mechanism of street vitality in mountainous cities, a new quantitative research method based on the new data environment and a Bayesian network is proposed. In this study, Python and GIS are used to obtain spatial data of streets, and Bayesian networks are used to construct street vitality models to identify important influencing factors and causal relationships between influencing factors. The results demonstrate strong causal dependencies between the factors influencing street vitality in mountainous cities. The mechanism of influence of street vitality revolves around functionality and street texture in terms of its own environment and external environment, respectively. The combination of factor group with functional density as the root node achieved the maximum probability of high vitality of the street. The results of this study have implications for community or urban planners with respect to urban regeneration and street vitality promotion.
