Building Information Modelling (BIM) technology has been widely used in the construction industry in recent years. However, to date, it still cannot sufficiently meet the requirements of construction practitioners in terms of the layout design of floor tiles. Recently, the BIM-based Parametric Design (PD) platform has presented considerable potential in automatically generating and optimizing floor tile layout design. In this paper, we propose a workflow to generate and optimize the layout design of floor tiles globally. To develop the workflow, we first formalize the design algorithm of floor tiles according to the trade know-how cutting and planning rules. Then, we combine the design algorithm with an evolutionary algorithm (EA) to generate and optimize the layout design for floor tiles automatically while minimizing material wastage. A prototype system is established in the ArchiCAD (BIM) and Grasshopper (PD platform) software. An apartment room tiling layout is used to demonstrate the feasibility and effectiveness of the proposed approach. Compared with the existing design methods, the proposed approach (1) reduces the material waste rate by 14.58% and 11.46%; and (2) improves the calculation efficiency and reduces the required computation time by 17.3 s to 50.0 s. Moreover, this research improves the existing design algorithm, enabling the BIM- and PD-based approaches to be used reliably in optimizing floor tile planning with arc-shaped boundaries. The outcomes are summarized in order to provide valuable insights in terms of floor tile waste reduction for further sustainable construction practice.

This comprehensive review critically examines current methodologies and optimization strategies for designing indoor thermal environments in educational buildings amid the challenges of global climate change and energy demands. The paper evaluates existing research methods, such as numerical simulations, data-driven models, and field measurements, revealing significant limitations in addressing the complex and dynamic nature of educational environments. It highlights the overemphasis on energy efficiency while neglecting user comfort and individual differences, such as students’ physiological and psychological needs. The review underscores the necessity of integrating human-centered design strategies, climate adaptability, and interdisciplinary approaches to improve building performance and enhance student well-being. Future research should focus on developing multimodal data fusion frameworks, applying AI-based optimization, and incorporating emerging technologies like BIM and IoT for dynamic management. By advocating for more adaptable and sustainable thermal environment strategies, this study provides a foundation for advancing educational building design in response to climate change and energy crises.

Improving living conditions, public services, and social safety nets in the aging residential areas is a core component of community renewal. Age-friendly development calls for integrated improvements in accessibility, safety, comfort, and aesthetics, which are essential for meeting the mobility needs of older adults and people with disabilities. Vertical transportation upgrades, especially elevators and barrier-free design, are critical interventions, yet the lack of a systematic evaluation framework has limited a comprehensive assessment of their effectiveness. This study aims to establish a comprehensive evaluation framework that tightly integrates age-friendly development with vertical transportation improvements, providing detailed guidance to support the renewal of aging residential communities. Methods: We adopted the PRISMA 2020 systematic review methodology, performing a structured search of the Web of Science Core Collection from 2014 to 2024. After applying rigorous inclusion and exclusion criteria, 61 studies were selected for in-depth analysis. Results: The review identifies four core dimensions—accessibility, safety, comfort, and aesthetics—that directly influence vertical transportation renovation outcomes. Key factors include step-free access such as ramps and slope compliance; elevator availability and reliability; lighting and anti-slip safety; waiting and riding comfort; and clear wayfinding through signage legibility. Innovation: Based on these findings, we propose an operational framework that not only defines these dimensions but also links them to measurable evaluation indicators and provides a step-by-step usage protocol. This framework enables policymakers and practitioners to design evidence-based renewal strategies, ensure equitable mobility for vulnerable groups, and promote sustainable, inclusive communities. The findings of this study can serve as a reference for future policy formulation, design practices, and empirical research on sustainable and age-friendly community renewal.
