Abstract

To achieve sustainability goals, it has become increasingly important to conduct post-occupancy evaluation (POE) to assess and understand the actual performance of green buildings (GBs). However, there has been little effort to provide researchers with a systematic and scientometric analysis of the state of the POE-in-GB field. To address this gap, this study aims to review the field and identify major trends and gaps that can be addressed in future research. This paper combined several state-of-the-art tools (i.e. Bibliometrix R-tool, Python BibexPy, VOSviewer, and Gephi) for an extensive bibliometric analysis based on 251 publications identified from Scopus and Web of Science. Utilizing a theoretical framework of office productivity, 35 empirical POE-in-GB studies were selected for further qualitative-systematic analysis. The quantitative-bibliometric analysis revealed that POE-in-GB research hotspots include energy efficiency, occupant satisfaction, thermal comfort, IEQ, LEED, and sustainability. The qualitative-systematic analysis focused on the physical environment quality and load, behavioural environment and the POE protocols of POE-in-GB. Some future research directions proposed include: exploring socio-psychological factors in POE-in-GB, developing standardized protocols for POE-in-GB, aligning GB certifications with user satisfaction, and integrating technology and big data into POE-in-GB. This study provides insights to academics and practitioners working in the POE-in-GB domain.

Abstract

Marine pollution threatens ecosystems, biodiversity, and human health, impacting species fitness, disrupting food webs, and degrading essential habitats. This review examines the effects of marine pollution on key species in the Salish Sea, a vital ecosystem supporting diverse wildlife, including endangered species, and local economies reliant on fishing, aquaculture, and tourism. In total, we synthesized 116 studies including chemical pollution (78), biological pollution (15), marine debris (15), and sound pollution (8). Research on marine chemical pollution has primarily focused on pollutants in fish (41), followed by studies on birds (11), mammals (7), and bivalves (7), then invertebrates (2). Future investigations should broaden species coverage, assess various life stages, and evaluate the impact of climate change on pollutant accumulation. Biological pollution, driven mainly by intentionally introduced species like farmed shellfish and salmon, threatens native species and can spread pathogens. There is a pressing need for research on the effects of fecal-borne pathogens on marine organisms and the influence of seagrass beds, fish farms, and sewage outfalls on pathogen dynamics. Marine debris, especially derelict fishing gear, negatively impacts local organisms, while the effects of tire reefs and microplastics remain poorly understood. Research should integrate laboratory and field assessments to analyze microplastic ingestion and improve detection technologies to inform conservation efforts. Noise pollution research has focused on marine mammals like killer whales, highlighting how sound pollution disrupts communication and behavior, which can indirectly alter food webs and community dynamics. Future studies should also encompass other marine species, including fish and invertebrates. Understanding pollution impacts is crucial for developing effective mitigation strategies, protecting marine life, and ensuring sustainable ocean resource management for future generations.

Abstract

Cities are renowned for catalyzing human interactions, but their distinctive environments also affect the interactions of other species. We discuss how urbanization affects species interactions and identify key knowledge gaps. With this context and using an eco-evolutionary lens, we frame urban environments as providing three consecutive filters: the presence of species, their co-occurrence and their relationships. Our framework offers a structured model for studying and managing urban species and environments to facilitate conservation and ecosystem services, benefiting urbanites of all stripes.

Portland Limestone Cement in Concrete Pavement and Bridge Decks: Performance Evaluation and Future Directions

Akerele, D. D., Aguayo, F., & Wu, L. (2025). Portland Limestone Cement in Concrete Pavement and Bridge Decks: Performance Evaluation and Future Directions. Buildings, 15(5), 660. https://doi.org/10.3390/buildings15050660

Abstract

With the rising demand for sustainable infrastructure, addressing the limitations of Ordinary Portland Cement (OPC) is crucial, particularly for exposed structures such as pavements and bridge decks. Portland limestone cement (PLC) is a sustainable alternative that delivers environmental benefits and comparable performance. This study used a systematic review and meta-analysis with a random-effects model to evaluate PLC’s strength development, durability, and sustainability. The findings indicate that PLC generally matches or surpasses OPC in terms of compressive strength, freeze–thaw resistance, and sulfate durability. However, its setting time and early-age cracking require further optimization, especially in cold climates. Additionally, this study highlights the fire performance advantages of PLC and its enhanced chloride resistance. The analysis identified critical research gaps, including long-term field performance and regional adaptation to extreme environmental conditions. These findings contribute to a deeper understanding of PLC’s role in sustainable construction and offer future research directions on hybrid cements and admixture compatibility.

Abstract

Facing urgent climate risks, many human and non-human actors are adapting to climate change with adaptations that sometimes shift vulnerabilities to other actors. Shifting vulnerabilities is a type of maladaptation and understanding them is a critical component of adaptation planning given the growing incidence of maladaptation across many sectors and regions. This review creates an analytical framework, called the Vulnerability Interactions Framework, to identify instances of shifting vulnerabilities from across the natural and social science literature and interpret them using a systematic approach. To demonstrate its utility, the analytical framework is applied in the context of coastal adaptation to sea level rise on the topics of coastal squeeze and wetland migration. Along certain shorelines, humans are building protective infrastructure, such as sea walls and levees, to protect themselves from sea level rise. Meanwhile, coastal wetlands—one of the world’s most valuable ecosystems—are able to adapt to sea level rise when they can migrate landward. This wetland adaptation is often blocked by human shoreline development and infrastructure—a phenomenon known as coastal squeeze. Yet migrating wetlands may also impact human actors in negative ways. This review identifies 53 distinct ways that vulnerabilities can shift across human and non-human actors on physical, economic, environmental, social, cultural, and institutional dimensions. These interactions reflect particular biophysical and social contexts and can operate on multiple spatial and temporal scales. Because of these complex interactions, adaptation planning must look towards developing solutions that are cross-sectoral and cross-scalar in scope, place adaptation within a larger socio-ecological context, consider a phased approach, engage with communities, build local adaptive capacity, and address personal, social, and cultural losses inherent in coastal transformations. Overall, the Vulnerability Interactions Framework can be used as a research or planning tool to map observed or hypothetical shifts in vulnerability.

Abstract

The construction industry is a significant contributor to global CO2 emissions, primarily due to the extensive use of ordinary portland cement (OPC). In response to the urgent need for sustainable construction materials, calcium sulphoaluminate (CSA) cement has emerged as a promising alternative. CSA cement is renowned for its low carbon footprint, high early-age strength, and superior durability, making it an attractive option for reducing the environmental impact of construction activities. While CSA cement offers benefits in carbon emissions reduction, its susceptibility to carbonation presents challenges. Although the body of literature on CSA cement is rapidly expanding, its adoption rate remains low. This disparity may be attributed to several factors including the level of scientific contribution in terms of research focus and lack of comprehensive standards for various applications. As a result, the present study sets out to track the research trajectory within the CSA cement research landscape through a systematic literature review. The study employed the Prefer Reporting Item for Systematic Review and Meta-Analysis (PRISMA) framework to conduct a literature search on three prominent databases, and a thematic analysis was conducted to identify the knowledge gap for future exploration. The study revealed that while CSA concrete demonstrates superior early-age strength and environmental resistance, its susceptibility to carbonation can compromise structural integrity over time. Key mitigation strategies identified include the incorporation of supplementary cementitious materials (SCMs), use of corrosion inhibitors, and optimization of mix designs. The review also highlights the global distribution of research, with notable contributions from the USA, China, and Europe, emphasizing the collaborative effort in advancing CSA concrete technology. The findings are crucial for enhancing sustainability and durability in the construction sector and advancing CSA binders as a sustainable alternative to traditional cement.

Abstract

The emerging recognition of the importance of urban habitat and wildlife for increasing biodiversity, driven partly by responses to climate change and urbanization, presents critical opportunities for urban biodiversity conservation and species recovery. However, effectively communicating these benefits to the public and policymakers remains a challenge for scientists and landscape architects with public perceptions, often shaped by diverse socio-cultural factors, serving as obstacles for garnering support. Our research explores innovative communication strategies through an intersectional analysis of planning and design communications and theory in museology and presents a structured approach in the use of charismatic species within interpretive studies to enhance public empathy and the potential for action. This research offers a valuable foundation for planning and design professionals, guiding their efforts to promote urban wildlife habitat and bridge the gaps between scientific knowledge and public advocacy.
