A Living wall system (LWS) is a biophilic design element that has been introduced into indoor environments in recent years. Previous studies have demonstrated that the LWS improves indoor visual comfort and air quality. However, studies on its psychological effects on occupants are still scarce. In this paper, the psychological effects were investigated by recording and analyzing the parameters of occupants’ physiological responses including an electroencephalogram (EEG) and heart rate variability (HRV). A cross-over experiment was conducted among 43 participants under three different desk work environments based on various materials involving an LWS, a fake LWS, and a bare white wall. The results conclude that LWSs effectively reduce the accumulation speed of negative psychological states caused by desk work to about 1/3, compared with a regular office environment without an LWS. However, occupants tend to be less excited and focused after resting in the LWS environment. Therefore, it is recommended to place LWSs in the rest area rather than close to the desk area in an office building, considering the balance between mental health and work efficiency.

China fully built a wealthy society but faced a serious COVID-19 epidemic together with the rest of the world. The emergence of the epidemic highlights the importance of sports parks for physical activity. By reviewing national fitness policies and identifying several types of sports parks, this paper investigates urban dwellers’ usage and preferences in sports parks by means of a questionnaire, with behavioural observation and interviews as complementary research methods. Taking the Beijing Olympic Forest Park, Sun Park, and Huilongguan Park as examples, this study reveals that participants present a high overall satisfaction with the sports parks. The factor analysis indicates that Sports Facilities and Maintenance & Management are the first and second most significant factors influencing residents’ willingness to use sports parks. This research can guide the planning and construction of sports park in the future.

Mature civil engineering software and platforms can provide a dynamic correlated situation of the road design, generate a quick and accurate grading design in terrain model making, and, most importantly, improve the design efficiency and calculation accuracy and reduce the workload of designers in the construction project. However, the application of existing platforms in complex site engineering for the design of ski tracks has not been well developed. The design process of ski tracks requires consideration of elaborate requirements in complex environmental conditions. In this study, we aim to simplify digital elevation model (DEM) data, optimize ski track contour lines, and localize the design expression of the ski track designs based on the experience of the construction of the National Alpine Ski Center in the Yanqing Competition Zone for the Beijing 2022 Winter Olympic Games. This study examines the feasibility of the optimal digital approach combining mathematics and computer science based on the case study of the warm-up and training ski track of the south area in the Yanqing Competition Zone. This study will contribute to the optimal design of skiing tracks in construction projects and help to improve designers’ workload efficiency for the design and construction of ski tracks in the future.

Yangshao Culture Museum of Yangshao Village national archaeological park (hereinafter referred to as the Museum) fully displays its characteristics, stimulated the regeneration of urban negative space by creatively adopting a sinking layout to hide modern building volume and introducing roof cover to reconstruct the regional landscape and public activity places. The museum meticulously balances the structural heat transfer coefficient with the surrounding sunshade considerations, utilizing software simulations to discern building morphology and intricate components. This approach guarantees the efficacy of the passive green building strategy.
