The gradual increase in the urbanization process over the years has increased the impervious surfaces while reducing green spaces, thereby contributing to the frequent occurrence of flash floods. The higher prevalence of flash foods has impacted the local authorities in spending huge amounts of costing for the purpose of repairing and cleaning the damaged public infrastructures. Therefore, numerous studies have proven the positive association between the availability of green infrastructures, namely green roofs, bioswales, and permeable pavements and their roles in minimizing stormwater runoff and flood risks in city area. However, there are limited studies which evaluate the economic worth of implementing these green infrastructures in preventing flash floods. Hence, it is vital to evaluate the potential long-term cost reductions from implementation of green infrastructure in flash flood mitigation to local authorities. Henceforth, this study aims to develop an economic model of the green infrastructure’s efficiency of green roof, permeable pavement, and bioswale in managing stormwater runoff. This study is conducted within the jurisdiction of Dewan Bandaraya Kuala Lumpur. It integrated data from systematic analysis from literature reviews and cost-benefit analysis based on interviews with local authorities to estimate the savings achieved through green infrastructure in flash flood management for local authorities. The findings show that the estimated cost savings by implementing green roof, permeable pavement and bioswale are approximately RM6,848, RM7,500 and RM6,875 per km² respectively. However, it is recommended to implement all three green infrastructures to maximize the overall effectiveness in reducing stormwater runoff and to achieve optimal cost savings from economic and environmental perspectives. This study is significant in promoting sustainable practices in infrastructure management and achieving the nation's Sustainable Development agenda.

Post-disaster permanent housing plays a critical role in long-term recovery. In cold-climate regions like Bingöl, Türkiye, such housing must ensure adequate thermal comfort and indoor air quality (IAQ) to support occupant well-being. This study evaluates the environmental performance of a representative single-storey post-earthquake housing unit constructed after the 2003 Bingöl earthquake. Field measurements were conducted between December 2023 and February 2024 in five rooms, recording temperature, relative humidity, air velocity, CO² concentrations and PM (PM₁–₁₀) levels. Results revealed that most rooms failed to meet ASHRAE 55 winter comfort thresholds, with temperature deviations exceeding 3.5°C in under-heated spaces. Stoves improved thermal comfort but elevated CO₂ and PM concentrations, indicating trade-offs between comfort and IAQ. Dynamic simulations using DesignBuilder tested envelope retrofit scenarios including insulation and glazing upgrades. Simulations showed a 7.1% reduction in discomfort hours, 60% lower heating energy demand, and a 12.3% drop in CO₂ emissions. These improvements were cost-effective and readily applicable in post-disaster contexts. This study contributes by combining field-based environmental data with simulation modelling to assess both thermal comfort and IAQ in cold-climate post-disaster housing. The findings inform resilient and sustainable housing strategies for future disaster recovery efforts.

Sports facilities are vital community assets, but their success depends on effectively integrating the often-divergent perspectives of architects and sports managers. This study investigates these contrasting perspectives through a mixed-methods approach, combining a comprehensive literature review with bibliometric analysis of publications indexed in the Web of Science. The literature review reveals a thematic divergence: architects prioritize the physical environment (indoor environmental quality, accessibility, long-term functionality), while sports managers emphasize service quality and the overall user experience (customer satisfaction, operational efficiency). The bibliometric analysis confirms this divergence, identifying six distinct research clusters with limited direct connections between them: "User-Centered Facility Management and Performance Evaluation," "Data-Driven Facility Management and Simulation Tools," "Design Quality, Access, and User Satisfaction," "Sustainability and Evaluation in Sports Facilities," "Operational Barriers and Efficiency in Facility Performance," and "Asset Management and Infrastructure-Oriented Facilities." This pattern highlights the disciplinary siloization in sports facility research. This study's main contribution is to provide empirical evidence of this fragmentation and to underscore the critical need for a more holistic and integrated approach encompassing both architectural design and facility management principles. Bridging this gap will lead to sports facilities that are not only aesthetically pleasing and structurally sound but also functionally effective, user-centered, and ultimately promote greater participation in sport and physical activity.

This review critically examines the development and performance of building-integrated photovoltaic (BIPV) shading systems, with emphasis on adaptive design strategies, energy optimization, and aesthetic integration. Following PRISMA-2020, we conducted a systematic review of English, peer-reviewed literature in Web of Science and Scopus for 2010-2024. We identified 2,699 records; after removing 525 duplicates, 601 automation-flagged ineligible items, and 216 records for other reasons, 1,357 records were screened. We excluded 619 at screening, sought 738 reports for retrieval (411 not retrievable), and assessed 327 full texts for eligibility; 190 were excluded (non-empirical 114, not peer-reviewed 56, full text unavailable 20). The final corpus comprised 27 studies (137 included reports) (Figure 1). Key quantitative findings from these studies indicate cooling-load reductiorns of 10-77%; adaptive systems achieving ≈65% daylight autonomy with DGP ≤ 0.25; rooftop systems yielding 50-70% more electricity than vertical facades; semi-transparent east façades delivering sDA ≈ 50-60% with DGP ≈ 0.30-0.40; and south-facing arrays at ~45° tilt reaching ~104 kWh·m - ²·yr - ¹. Three trends emerge: (1) a shift toward adaptive façades using real-time, AI-driven controls to balance energy and visual comfort; (2) growing use of multi-objective simulation frameworks coupling energy, daylighting, and thermal analyses; and (3) heightened attention to aesthetic coherence and user perception. Despite progress, challenges persist in life-cycle validation, standardized evaluation, and cross-disciplinary integration. The paper concludes with a framework that couples dynamic-shading logic, architectural aesthetics, and performance-based simulation to guide future BIPV façade research. Unlike previous reviews that consider energy or daylight in isolation, this study integrates typological design, energy/thermal/visual performance, and aesthetic/user acceptance into one comparative framework, providing decision-ready ranges and trade-off matrices for BIPV shading.

Thermal treatment of waste materials is identified as one of the potential methods in waste management practice. The method is currently implemented in Malaysia for municipal solid waste and it is believed that thermal treatment processes are suitable too for certain types of construction waste materials. Therefore, this study aimed to identify the chemical properties of construction waste materials in terms of moisture content, volatile matter, ash content and fixed carbon through proximate analysis to determine the possible construction waste materials that can be included in thermal treatment processes. The findings of the proximate analysis showed that wood waste recorded 85.11% volatile matter with 1.28% ash content, while plastic waste recorded 90.19% volatile matter with 7.50% ash content. It was understood that the higher the percentage of volatile matter in a particular material, the longer the combustion process, hence, the higher the heating value might be generated. For that reason, wood and plastic waste from the construction industry could be a great source for thermal treatment processes and heat energy generation since both materials are highly volatile matter with relatively low ash content or residuals. The minimal residuals could preserve our landfill space and lessen the environmental impacts.
