There is mounting evidence suggesting that workplace design directly connects with workers’ health and wellbeing. Additionally, the personal status of the mind can affect subjective attitudes and feelings towards the environment. In this study, the impacts of biophilic design attributes in offices on workers’ health and wellbeing are examined. A new post-occupancy evaluation (POE) questionnaire is developed for evaluating the biophilic design for workplace health and wellbeing. A questionnaire and field observations of two green building offices in Singapore and Shenzhen, China, are performed. The main obtained results are: (i) the questionnaire results show that the workers have a moderately high evaluation of the biophilic attributes in the workplace for improving health and wellbeing; (ii) there are significant differences between the self-reported health and nature relatedness of various ages and genders. Furthermore, the present study provides designers with new weighted biophilic design guidelines, specifically for workplace design practices.

To achieve the goals of carbon peaking, a national policy instrument for carbon peaking in the building and construction sector has been launched by the Chinese MOHURD (30 June 2022). We have developed an actionable framework for implementing these policy objectives. The framework was designed by classifying and prioritizing selected strategic government recommendations in the form of an interactive indicator system and tool for evaluating the quality of low-carbon urban and neighborhood planning actions based on the decarbonation principles of carbon emission reduction and carbon capture. The analytic network process (ANP) was applied for processing the interactions and prioritizing the indicators (23 in total for the two principles applied). A scorecard was designed for assessing low-carbon urban and neighborhood planning strategies and technologies. The practical implementation of the tool was then tested with two real planning cases, one from a fourth-tier Chinese city and another from a high-density city. The applicability of the tool is further discussed by comparing it with well-developed international assessment tools in other contexts. This article contributes to the literature by first initiating research on the use of this evaluative tool for low-carbon planning and secondly by demonstrating how researchers can convert policies into practical implementations.

Children and adolescents in hot and humid climates face increasing health risks due to climate change. Although the concept of Health-Promoting Schools (HPSs) is widely recognized, a systematic framework that integrates climate adaptability, child-specific needs, and multidimensional environmental design is still lacking. To address this gap, this study conducted a systematic literature review of 89 publications with three objectives: (1) synthesize research from the past decade on the impact of school physical environments on the health and academic performance of children and adolescents; (2) develop an evidence-based synergistic design framework with a categorized indicator system; and (3) integrate qualitative and quantitative evidence on how these indicators influence different health dimensions. The resulting framework emphasizes multidimensional, synergistic optimization and provides climate-responsive design strategies tailored to educational settings in hot and humid regions. By offering a theory-to-practice pathway, the framework complements existing healthy building guidelines for K–12 schools and supports designers and policymakers in creating environments that enhance thermal resilience, cognitive performance, and holistic child development.

Conventional evaluations of indoor environmental quality (IEQ) in office spaces are typically disproportionately influenced by expert experience, often overlooking the cognitive gap between decision makers (experts) and users (employees). To quantify and explain this discrepancy, this study develops a comprehensive evaluation framework including 20 IEQ indicators, grounded in Maslow’s hierarchy of needs. Using the Shenzhen Science Park as a case study, evaluation data were collected from 13 experts and 432 employees. The Analytic Hierarchy Process (AHP) and the Kano model were applied to calculate expert weights and employees’ nonlinear sensitivities, respectively, followed by the construction of an optimization matrix via Importance–Performance Analysis (IPA). The results reveal a notable cognitive gap: experts prioritize foundational physical elements regarding spatial technology, whereas employees place greater emphasis on factors such as privacy protection and flexible layouts. Both groups concur that “noise interference” and “lack of privacy” are the primary shortcomings of open-plan offices. Prospective assessments indicate that embodied AI-enabled robots currently remain in a “early adoption phase,” with employees showing no functional dependency on them. This study confirms that merely improving building physical performance does not proportionally translate to increased employee satisfaction. Spatial optimization should adopt a human-centric approach, emphasizing acoustic control and the reconfiguration of privacy boundaries to enhance the scientific allocation of resources.
