One trend in building design is building envelopes with perforated patterns, which create a sculptural envelope using parametric and generative design tools to adapt to environmental conditions and user preferences. However, there are gaps in understanding the potential benefits of perforated building envelopes (PBEs) and their key design parameters used in contemporary projects. Therefore, this study aims to examine the classification of PBE design parameters and their commonly used parametric design tools that provide appropriate indoor environmental quality (IEQ) for buildings. The study is based on (1) a review of relevant studies, and (2) an analysis of case studies of contemporary projects. The results reveal relationships between key design variables of contemporary PBEs based on a conceptual framework developed in terms of (a) general building properties, (b) detailed envelope properties, and (c) environmental performance indicators. This study contributes to the field of architecture by providing a design strategy for creating PBEs based on a parametric approach and highlights the importance of considering IEQ in the early digital modelling process. By applying the five-stage strategy: creativity, configuration, generation, performance, and evaluation, it was found that PBEs can be a powerful tool to enhance energy efficiency by about 26.91% compared to glazed envelopes in Egypt, which may lead to improved IEQ. Future research could apply the proposed strategy to explore the impact of PBEs on various IEQ indicators.

Purpose: Online learning has many limitations in studio-based courses, such as architectural design courses, considering the challenges during post-pandemic. Therefore, this study aims to propose a post-pandemic adopted learning approach, which integrates flipped classrooms (FC) with project-based learning (PBL). In addition, this study evaluates the perceptions of students based on and the effects of the proposed learning approach in architectural design. Design/methodology/approach: This study provides a mixed methodology based on a literature review on the topic to bridge the gaps in previous studies regarding the FC and PBL. In addition, a case study survey including semi-structured interviews, observations questionnaire recruited undergraduate students to generate both qualitative and quantitative data to investigate the perceptions of students based on post-pandemic adopted learning approach. Findings: This study has highlighted the significance of post-pandemic adopted hybrid learning method, especially in architectural education, whereas the research finds that FC is an appropriate solution to improve design courses with online technologies. Practical implications: The proposed approach provides specialists to develop and integrate proposals and strategies to enable a better online practice for students and instructors. The proposed approach can enhance the students' interpersonal skills, hence active online learning related architectural design projects. Originality/value: Recognizing the significance of e-learning in response to the post-pandemic scenario, this study developed and assessed new learning technique that combines online learning with traditional design studios via hybrid learning method.

Intending to improve building performance and environmental sustainability, vertical greenery systems (VGSs) are employed as effective nature-based solutions (NbSs), yet they often struggle to meet modern building energy demands alone. This study investigates the integration of VGSs with advanced façade technologies (AFTs) to develop multifunctional hybrid façades. A systematic review was conducted following PRISMA 2020 guidelines, combining bibliometric and thematic analyses of 415 publications (2015 to early 2026) from Scopus and Web of Science. The study categorizes AFT into adaptive, energy-generating, and high-performance façades. The results indicate that VGS–photovoltaic (PV) systems and double-skin (DS) systems are the most studied integration scenarios, providing significant thermal regulation and energy efficiency. However, significant gaps remain for kinetic, modular, bioactive, and glazing systems, particularly regarding standardized workflows and long-term lifecycle assessments (LCAs). The study reveals a transition of VGSs from passive aesthetic elements to active building components. To address these identified gaps, a four-phase design strategy—conceptualization, hybridization, optimization, and development—is proposed to guide architects and engineers in decision-making regarding generating optimized hybrid façades. Integrating VGSs with AFTs is essential for urban resilience and an alignment with Sustainable Development Goals. Future research should prioritize standardized integration protocols and the application of smart technologies like artificial intelligence (AI).
