Abstract

The built environment plays a crucial role in global sustainability efforts. Buildings, infrastructure, and cities consume large amounts of energy and materials that shape social behavior, and lock in environmental impacts. Over the past two decades, research has produced a wide range of technical solutions to reduce these impacts. Renewable energy systems, energy-efficient buildings, alternative construction materials, and new construction methods are no longer experimental concepts. Many have proven technical and economic potential. Yet, real-world transformation remains slow and uneven. This gap suggests that sustainability challenges in the built environment are no longer driven by a lack of technology. Instead, they are shaped by how technologies are adopted, governed, financed, and embedded within existing systems. The papers in this issue tried to understand this challenge from different scales and contexts. Together, they show that sustainability is best understood as a socio-technical transition, where technical solutions must align with institutions, markets, spatial structures, and human practices.

Abstract

Global awareness of climate change impacts has compelled the power sector to adopt renewable energy as a primary source of electricity, driving innovation in renewable energy business models. This study analyzes the feasibility of Energy as a Service (EaaS) with a Third-Party Ownership (TPO) scheme for utility-scale solar photovoltaic (PV) development in the fast-moving consumer goods (FMCG) industry. Four scenarios of utility-scale solar PV configurations under the EaaS model are evaluated: on-grid ground-mounted (OG-GM), hybrid ground-mounted (H-GM), on-grid floating (OG-F), and hybrid floating (H-F). All scenarios are developed under the assumption of utilizing the PLN grid through a power wheeling lease agreement. The optimal capacity for each scenario is determined using HOMER Pro, followed by an economic analysis to identify the most viable configuration. The results indicate that both on-grid and hybrid configurations can support the consumer’s objective of achieving 100% renewable energy usage. Among the evaluated scenarios, on-grid floating solar PV emerges as the most viable option, providing benefits for both consumers and EaaS providers, including potential electricity cost savings of 16% and avoided emissions of up to 41,299 tons of CO₂ per year. To fully achieve 100% renewable energy consumption, consumers must transition to hybrid configurations, enabling an emission-free electricity system and eliminating the need for Renewable Energy Certificate (REC) purchases. This transition can generate potential annual savings of USD 40,590.96, although it results in an increase in electricity costs of up to 117% due to the integration of battery energy storage systems without grid support. Overall, the implementation of the EaaS TPO model offers mutual benefits for both consumers and energy service companies and can serve as a catalyst for accelerating renewable energy deployment in Indonesia.

Abstract

Construction, mining, and manufacturing are the most significant contributors to South Africa's GDP. While manufacturing and other industries utilise advanced technologies to enhance productivity, he construction industry continues to lag behind in technological adoption. This study examines the barriers that hinder the South African construction industry from leveraging the benefits of modular construction technologies (MCT). The study employed a quantitative research method, using closed-ended questions to collect data. The questionnaires were emailed to South African construction industry professionals selected through a combination of purposive and convenience sampling. A total of 98 questionnaires were distributed, of which 46 were returned. However, only 41 were deemed valid for analysis, and five incomplete responses were excluded. The data obtained were analysed using descriptive statistics. The study highlighted that modular construction technology is not yet widely encouraged in the South African construction industry. This indicating a need for increased awareness and education regarding this technology. Some barriers to the adoption of modular construction include a lack of knowledge among construction stakeholders, aesthetic concerns, difficulties in making changes, limited contractor expertise in modular construction, and transportation constraints. The lack of adoption of modular construction technology in South Africa deprives the industry of the benefits associated with this construction method, such as improved production efficiency, which have been realised by other sectors that have successfully adopted advanced technologies in their production processes. Therefore, construction industry stakeholders should implement targeted measures to address adoption barriers. The study provides a clearer and more comprehensive understanding of the perceptions of industry stakeholders regarding the factors that hinder the adoption of modular construction technology.

Abstract

Urban areas in Indonesia, particularly the Greater Jakarta metropolitan region (Jabodetabek), are increasingly experiencing the adverse effects of climate change, such as the Urban Heat Island (UHI) phenomenon. Rapid urbanization has contributed significantly to rising greenhouse gas emissions and deteriorating environmental quality. Urban forests are one of the key solutions to mitigate these impacts; however, their spatial distribution in Jabodetabek remains suboptimal and poorly connected. This study uses NDVI as a proxy for urban forest density, where “urban forest” refers to vegetated areas within cities as defined by Presidential Regulation No. 60/2020. The research addresses the following question: How has urban forest connectivity across Jabodetabek changed over a 30-year period? Using multi-temporal Landsat satellite imagery, the Normalized Difference Vegetation Index (NDVI) was employed to identify vegetation cover and assess temporal changes in urban forest density. NDVI values were processed using ArcPy in ArcMap, followed by spatial reclassification to identify areas of degradation or regeneration. The analysis reveals fragmented and disconnected urban forests across Jabodetabek, with some areas experiencing vegetation loss of up to 40.3%, while others show a gradual recovery of up to 33.9%. The dynamics along the Bekasi River indicate that upstream and downstream areas remain connected, but are disrupted in the peri-urban–to–suburban transition zone, creating ecological gaps that interrupt continuity. This challenge is further compounded in urban areas, particularly Jakarta, where urban forests are not yet ecologically or administratively connected. These findings emphasize the urgency of strengthening urban forest connectivity to enhance ecological resilience and climate adaptation in Jabodetabek.

Abstract

This paper examines the socio-economic and infrastructure conditions that determine Ghana’s readiness to adopt alternative infrastructure funding models (AIFMs) for sustainable road development. The objective of the study is to identify the macroeconomic and sectoral drivers of AIFMs’ adoption and to develop policy frameworks for the sustainable financing of infrastructure within Ghana’s context. Ordinary Least Squares (OLS) regression analysis is applied to annual data from 2003 to 2023 to examine the relationship between macroeconomic and infrastructure indicators and economic growth , which is used as a proxy for the viability of AIFMs. The results show that employment growth, educational attainment, and road network expansion are positive contributors to growth. On the other hand, per capita income and governance indicators exhibit a negative relationship with economic growth, suggesting institutional inefficiencies and governance gaps. The impacts of access to healthcare and electricity are mixed and relatively modest, indicating that their role in the adoption of AIFMs depends on institutional and policy integration. The results highlight that fiscal capacity and socio-institutional quality affect AIFMs’ preparedness in Ghana. Based on these results, this study proposes a locally contextualised decision-making framework that incorporates macroeconomic indicators, infrastructure capacity, and social access considerations into infrastructure policy evaluation and funding decisions. The framework translates quantitative findings into a practical model for use in decision-making, providing policymakers with an effective tool for selecting sustainable AIFMs in Ghana.

Abstract

Urban compactness has traditionally been measured through density, with population per area used as a core indicator of urban form. However, this method creates a limited view of what compactness means. Research shows that a compact city is not always a high-density city, and that increasing density does not automatically result in compact development. Compactness also involves the shape and structure of urban footprints, which influence how land is used and how a city functions. This paper presents a conceptual distinction between density and shape compactness, arguing that both are necessary to understand urban form. A qualitative literature review was conducted to examine how cities with similar density levels can show major differences in spatial structure and performance. The findings suggest that density and shape are separate components of urban form. This paper proposes a broader measurement framework that includes both factors, which can improve spatial planning, urban design, and policy decisions.

Abstract

Locust Bean Pod Ash (LBPA) is produced from the calcination of Locust Bean Pod (LBP), an agricultural waste of the African locust bean tree (Parkia biglobosa). This study evaluated the use of LBPA obtained through controlled calcination and open burning as a supplementary cementitious material (SCM) in high-strength concrete (HSC). Cement was replaced by LBPA at 5%, 10%, 15%, and 20% by weight using both ashes—LC for ash produced through calcination at 600 °C, and LO for ash obtained through open burning. Slump and strength were assessed, including compressive strength (100 × 100 × 100 mm cubes) and splitting tensile strength (100 × 200 mm cylinders) up to 90 days. The results showed that LC contained 42.81% and LO contained 10.69% combined SiO₂, Al₂O₃, and Fe₂O₃. The 5% replacement level produced the best performance for both LBPA types. At 90 days, LC and LO improved compressive strength by 14.48% (68.8 N/mm²) and 10.48% (66.4 N/mm²), respectively, compared to the control (60.1 N/mm²). Similarly, the tensile strengths of LC05 and LO05 were 6.74% (4.75 N/mm²) and 4.94% (4.67 N/mm²) higher than the control (4.45 N/mm²). The study concludes that both ashes can be used as SCMs in HSC, with 5% and 10% recommended as optimum replacement levels for calcined and openly burnt LBP, respectively.

Abstract

Smart buildings have become a key part of the Fourth Industrial Revolution, driven by the need for efficient, sustainable, and adaptive built environments. Their importance is growing alongside Indonesia’s effort to develop smart cities. This study compares Indonesia’s national smart building certification system, established under Ministerial Regulation No. 10 of 2023, with two international systems: the European Union’s Smart Readiness Indicator (SRI) and the SmartScore certification. The analysis uses a literature review and comparative method to examine each system’s assessment criteria, scoring method, and certification tier. The findings show that Indonesia’s regulation includes six parameters, such as cybersecurity and operational management. SRI covers nine technical domains with emphasis on energy efficiency and occupant comfort. SmartScore focuses on user functionality and technological foundation. The comparison shows both overlap and variation in technical coverage, sustainability goals, and adaptability to climate and user needs. Although Indonesia’s system is comprehensive, it would benefit from closer alignment with international standards and stronger regulatory support to improve adoption and building performance. This study recommends more government incentives, better infrastructure, and stronger stakeholder education to support smart building development in Indonesia.

Abstract

The construction sector plays a critical role in urban development and economic growth, yet it continues to face major challenges that threaten worker health and safety. Traditional safety measures are not always sufficient for the complex conditions found on construction sites, which creates a need for technology‑based solutions. This study investigates the relationship between technology adoption and health and safety practices in the construction industry in Lagos, Nigeria. The study identifies the major causes of site accidents, examines the level of technology use on construction sites, and reviews existing literature through both primary and secondary data. Primary data were collected from registered construction professionals, while secondary data were obtained from journals and conference papers. Questionnaires were distributed through email and social media platforms, and 141 valid responses were received. Findings show that the leading causes of construction hazards were lack of training (mean = 3.79) and non‑compliance with safety procedures (mean = 3.70). The overall level of technology adoption for site safety was low (mean = 2.75), although some tools were more widely used than others. The most significant barrier to adoption was the high cost of acquiring new technologies (mean = 4.52). Statistical analysis showed a strong positive correlation between technology adoption and accident reduction (r = 0.62, p = 0.001). Technology‑based safety training was significantly associated with improved compliance (χ² = 12.45, p = 0.002). Wearable technology also had a significant effect on incident reporting (F = 4.76, p = 0.012), and access to mobile safety applications showed a positive correlation with risk reporting (r = 0.45, p = 0.045). Overall, the study concludes that technology contributes positively to construction health and safety in southwestern Nigeria. The study recommends increased investment in training, awareness programs, and financial support to encourage wider adoption of safety technologies.

Abstract

Shading devices are essential for reducing solar radiation and cooling loads in buildings located in tropical climates. In the Jakarta region, the highest solar factor is observed on west- and east-facing facades, followed by north- and south-facing orientations. National building policy in Indonesia encourages facades to face north–south to reduce solar heat gain. This study explores horizontal static and dynamic shading devices on north-facing facades and evaluates their impact on cooling load reduction and daylight performance. The methodology includes calculating and simulating energy use intensity (EUI) using EnergyPlus and conducting illuminance analysis using Radiance and Grasshopper. Key parameters considered in the shading design include sun position, illuminance levels, and EUI. The results show that static shading devices with a fixed tilt angle of 20° and a depth of 1.2 m reduce the cooling load by 15.82% while ensuring that at least 30% of the workspace floor area receives an average illuminance of 300 lux throughout the year. Meanwhile, dynamic shading devices with adjustable tilt angles ranging from 10° to 40°, following the sun’s position, reduce the cooling load by 15.75%–18.83%. This configuration consistently ensures that at least 30% of the workspace floor area achieves 300 lux of illuminance each month. These findings provide a practical reference for the design of north-facing shading devices in tropical climates, balancing thermal performance and daylight availability.
