The study examines how design quality, indoor air quality, and energy efficiency affect customer satisfaction in eco-friendly houses in Shanghai, China. Further, it examines how environmental awareness mediates community participation and resident satisfaction. A stratified sampling technique is used to collect the data from 742 eligible respondents in public and private eco-residential complexes. The results show that design, air quality, and energy efficiency improve customer satisfaction. At the same time, community engagement partially mediates these correlations, stressing the importance of social cohesion in enhancing residential area quality. Environmental awareness moderated the effects and boosted the happiness benefits of energy efficiency and indoor air quality. This research uses a comprehensive framework that includes psychological, environmental, and social components to make it stand out. Instead of studying green housing benefits in general, it accomplishes this inside China’s urban sustainability program. The results help policymakers, urban planners, and housing authorities make megacity green housing more desirable and livable.

The awareness level of residents to prevent crime is increasing while the characteristics of the physical environment and atmosphere within the residential areas have been utilized to discourage crime. Crime Prevention through Environmental Design (CPTED) as an effective crime prevention strategy has been introduced since 1971 where it evolved from the first-generation to second-generation after including intangible components into the practices. Currently, the emergence of digital technologies such as Building Information Modelling (BIM) has started to gain more attention from academicians and practitioners. The features in BIM such as simulation, visualizing and estimating should be utilized to enhance CPTED effectiveness in preventing crime which will form the fundamental of third-generation CPTED. This study intended to explore the potential to integrate BIM into existing CPTED to develop a third-generation of CPTED. Therefore, this study has reviewed the journal articles pertinent to the BIM application in CPTED which elaborate the potential of BIM to be used practically to provide new concept of third-generation CPTED which embracing digital technology. This study found the potential of BIM to integrate with four tangible principles (surveillance, access control, territoriality and target hardening) and two intangible principles (sense of community, and management and maintenance) have been discussed. All existing principles can be integrated with BIM to further enhance their effectiveness but there are some conflicts found between the principles practiced in CPTED. This study has provided a comprehensive overview of the integration of BIM to CPTED practitioners for the development of third-generation CPTED in future research.

As property development and information technologies are going rapid in these few decades, information construction becomes necessarily as a management tool. Changes and variations in construction projects are common and inevitable. This paper aims to study potentials of Building Information Modelling (BIM) in managing variations. The research objective is to identify the potentials of BIM in managing variations. Qualitative method was adopted for this research. Semi-structured interviews were conducted with the respondents to collect data. Twelve respondents were chosen based on the following criteria: (a) involved in BIM projects and (b) experts with BIM knowledge. The respondents involved in the interviews are BIM software providers, BIM software resellers, BIM consultants, main contractors and government personnel in Malaysia. From the interview findings, the potentials of BIM in managing variations are to reduce the variations due to design-related changes, material-related changes, information discrepancies and construction method. Resolving design-related changes includes better visualisation, design coordination, clash detection, better decision making and minimised uncertainties. Managing material-related changes involves automated quantity taking-off, detailed plan for visualisation and material purchase plan. Reducing information discrepancies involves data digitalisation, communication and collaboration, real-time tracking changes as well as improved on request for information (RFI) process. Minimising variations due to construction method includes simulation, better site management and prefabrication with BIM. This research proves that it is necessary to promote BIM management approach in managing variations.
