Although The Edge is widely recognized as one of the most sustainable office buildings in the world, the specific contribution of key material choices, such as concrete used in the structural system, remains unclear. This article examines the environmental impact of the concrete used in The Edge using a life cycle analysis using the software BEES Online 2.1 and the ISO methodology. Because there is little detailed information available about the exact type and volume of concrete, assumptions were made based on reference projects such as other BREEAM-certified projects. The analysis considers the full life cycle of the concrete used from raw material extraction to end-of-life scenarios (cradle-to-grave approach). The results of this research provide insights into the actual contribution of concrete to the reduced ecological footprint achieved through the use of supplementary cementitious materials, such as fly ash and blast furnace slag, both identified as potential alternatives used in this project. These results certainly contribute to a better understanding of how important material choices are to a building’s sustainability performance, particularly in green-certified buildings. Full article

The technocratic and economically driven approach to urban and industrial planning can be observed in the evolution of modern logistics parks, which have become key infrastructural elements of regional development. This study explores how technocratic logic influences the spatial and environmental transformation of logistics parks in Poland within the context of sustainable certification systems such as BREEAM International (Building Research Establishment Environmental Assessment Method). The research employed an eight-stage methodological framework combining exploratory, analytical, and empirical methods. The process began with a comprehensive literature and data query on the development of logistics parks at global, European, and national levels, followed by a systematic review of sustainability assessment systems. A research framework was then defined to establish a consistent model of warehouse buildings, verified through the PLGBC database of certified facilities. The dataset was filtered and standardized, and a purposive sample of 25 BREEAM-certified warehouses was selected from 150 eligible cases. Each certification report was analyzed to identify credit distribution patterns, and the results were examined through a factor analysis to interpret the technocratic and systemic determinants influencing sustainability decisions. The findings reveal that the decision-making logic of developers is dominated by quantitative optimization and regulatory alignment, leading to the prioritization of low-cost, easily verifiable credits such as ENE03 (External Lighting) and WAT02 (Water Monitoring), while complex or innovative credits such as MAT06 (Material Efficiency) remain under implemented. The study contributes to the understanding of how technocratic rationality shapes sustainable certification outcomes and highlights the need for stronger policy and market incentives to promote circular and systemic approaches in the logistics real estate sector.

This study compares certification systems for green healthcare facilities implemented worldwide. Healthcare facilities are complex structures designed to provide uninterrupted service while involving substantial resources, high energy consumption, and heavy human and material traffic. The COVID-19 pandemic emphasized the importance of designs that ensure hygiene, reduce environmental impact, and improve energy efficiency, making green certification systems for healthcare facilities increasingly critical. Eight certification systems currently in use across eight countries were examined, four from advanced economies (LEED in the U.S., BREEAM in the U.K., Green Star in Australia, and CASBEE in Japan) and four from developing economies (YeS-TR in Türkiye, IGBC in India, GBI in Malaysia, and GREENSHIP in Indonesia). Country selection considered regional diversity, similarities in environmental policies, and the potential for healthcare infrastructure development. A literature-based comparative analysis was conducted, and seven key categories were identified for evaluating sustainability: sustainable land and transport, water and waste management, energy efficiency, material and life cycle impact, indoor environmental quality, project management process, and innovation. The comparison revealed considerable overlap among the systems but also highlighted shortcomings in addressing healthcare-specific needs. This paper contributes to the advancement of sustainability assessment in the healthcare sector by highlighting the need for certification schemes specifically designed for medical facilities. The findings emphasize the necessity of developing healthcare-tailored frameworks that not only address environmental performance but also capture the unique operational, functional, and clinical dynamics of this sector.

Cities around the world are facing growing challenges related to climate change, urban sprawl, infrastructure strain, and digital transformation. In response, smart and sustainable urban development has become a global focus, aiming to integrate technology and environmental stewardship to improve the quality of life. The smart and sustainable city concept is typically applied at the city scale; however, its impact is most tangible at the neighborhood level, where residents interact directly with infrastructure, services, and community spaces. A variety of global frameworks have been developed to assess sustainability and technological integration. However, these models often fall short in addressing localized needs, particularly in regions with distinct environmental and cultural contexts. In Saudi Arabia, Vision 2030 emphasizes livability, sustainability, and digital transformation, yet there remains a lack of tailored tools to evaluate smart and sustainable progress at the neighborhood scale. This study develops HayyScore, a localized evaluation framework and prototype digital platform developed to assess neighborhood performance across five core categories: (i) Environment and Urban Resilience, (ii) Smart Infrastructure and Governance, (iii) Mobility and Accessibility, (iv) Quality of Life and Social Inclusion, and (v) Economy and Innovation. The HayyScore platform operationalizes this framework through an interactive web-based tool that allows users to input data through structured forms, calculate scores, receive category-based and overall certification levels, and view results through visual dashboards. The methodology involved a comprehensive review of global frameworks, expert input to define localized indicators, and iterative prototyping of the platform using Python 3.13.5 and Streamlit 1.45.1. To demonstrate its practical application, the prototype was tested on two Saudi neighborhoods: King Abdullah Petroleum Studies and Research Center (KAPSARC) and King Fahd University of Petroleum and Minerals (KFUPM). Key platform features include automated scoring logic, category weighting, certification generation, dynamic performance charts, and a rankings page for comparing multiple neighborhoods. The platform is designed to be scalable, with the ability to add new indicators, support multilingual access, and integrate with real-time data systems in future iterations. Full article

The current green building assessment system suffers from issues such as insufficient coverage of smart indicators, significant biases in subjective weighting, and weak dynamic adaptability, which restrict the scientific promotion of green buildings. This study focuses on the gaps in the quantitative assessment of smart technologies in China’s green building evaluation standards (such as the current Green Building Evaluation Standard). While domestic standards are relatively well-established in traditional dimensions like energy conservation and environmental protection, there are fragmentation issues in the assessment of smart technologies such as the Internet of Things (IoT) and BIM. Moreover, the coverage of smart indicators in non-civilian building fields is significantly lower than that of international systems such as LEED and BREEAM. This study determined the basic framework of the evaluation indicator system through the Delphi method. Drawing on international experience and contextualized within China’s (GB/T 50378-2019) standards, it systematically integrated secondary indicators including “smart security,” “smart energy,” “smart design,” and “smart services,” and constructed dual-drive evaluation dimensions of “greenization + smartization.” This elevated the proportion of the smartization dimension to 35%, filling the gap in domestic standards regarding the quantitative assessment of smart technologies. In terms of research methods, combined weighting using the Analytic Hierarchy Process (AHP) and entropy weight method was adopted to balance subjective and objective weights and reduce biases (the resource conservation dimension accounted for 39.14% of the combined weights, the highest proportion). By integrating the grey clustering model with the whitening weight function to handle fuzzy information, evaluations were categorized into four grey levels (D/C/B/A), enhancing the dynamic adaptability of the system. Case verification showed that Project A achieved a comprehensive evaluation score of 5.223, with a grade of B. Among its indicators, smart-related ones such as “smart energy” (37.17%) and “smart design” (37.93%) scored significantly higher than traditional indicators, verifying that the system successfully captured the project’s high performance in smart indicators. The research results indicate that the efficient utilization of resources is the core goal of green buildings. Especially under pressures of energy shortages and carbon emissions, energy conservation and resource recycling have become key priorities. The evaluation system constructed in this study can provide theoretical guidance and technical support for the promotion, industrial upgrading, and sustainable development of green buildings (including non-civilian buildings) under the dual-carbon goals. Its characteristic of “dynamic monitoring + smart integration” forms differentiated complementarity with international standards, making it more aligned with the needs of China’s intelligent transformation of buildings.

This study examines the integration of Environmental, Social, and Governance (ESG) principles within Romania’s residential real estate sector, concentrating on Constanța, a rapidly evolving urban centre in a transitional economy. Drawing on qualitative data from semi-structured interviews with local real estate professionals and secondary analysis of policy and market documents, the research uncovers inconsistencies in ESG implementation. Environmental compliance is advancing, largely driven by EU regulations such as the European Grean Deal, the Corporate Sustainability Reporting Directive and the Energy Performance of Buildings Directive. Voluntary certification schemes like BREEAM and LEED are emerging as benchmarks for environmental performance; however, their uptake remains limited and insufficiently tailored to local conditions. Meanwhile, the social and governance dimensions lag behind, characterised by inconsistent application and weak institutional backing. Key barriers to effective ESG integration in Romania’s residential real estate sector include weak regulatory enforcement, fragmented policies, limited green finance, low awareness, and a lack of standardised social value metrics. The study concludes that without moving beyond mere regulatory compliance to a framework embedding social inclusivity and adaptive governance, ESG efforts risk perpetuating existing inequalities. It calls for a reconceptualisation of ESG frameworks, developed for mature markets, to better suit transitional urban contexts and support long-term resilience in residential real estate.

The construction of prefabricated concrete houses in Ecuador poses significant challenges in terms of environmental and social sustainability, amid growing housing demand and the urgent need to mitigate adverse impacts associated with the construction processes and materials. In particular, the lack of a comprehensive assessment of these impacts limits the development of effective strategies to improve the sustainability of the sector. In addition, in rural areas, the design of flexible and adapted solutions is required, as evidenced by recent studies in the Andean area. This study conducts a comprehensive assessment of the impacts and sustainability indicators for prefabricated concrete houses, employing international certification systems such as LEED, BREEAM, and VERDE, to validate various relevant environmental and social indicators. The methodology used is the Hierarchical Analytical Process (AHP), which facilitates the prioritization of impacts through paired comparisons, establishing priorities for decision-making. Hydrological, soil, faunal, floral, and socioeconomic aspects are evaluated in a regional context. The results reveal that the most critical environmental impacts in Ecuador are climate change (28.77%), water depletion (13.73%) and loss of human health (19.17%), generation of non-hazardous waste 8.40%, changes in biodiversity 5%, extraction of mineral resources 12.07%, financial risks 5.33%, loss of aquatic life 4.67%, and loss of fertility 3%, as derived from hierarchical and standardization matrices. Despite being grounded in a literature review and being constrained due to the scarcity of previous projects in the country, this research provides a useful framework for the environmental evaluation and planning of prefabricated housing. To conclude, this study enhances existing methodologies of environmental assessment techniques and practices in the construction of precast concrete and promotes the development of sustainable and socially responsible housing in Ecuador.

This study compares the LEED, BREEAM, and WELL certification systems using the Triple Bottom Line (TBL) framework to assess their performance across environmental, social, and economic dimensions and their alignment with sustainable development goals. A structured secondary analysis was conducted on over 50 peer-reviewed articles, case studies, and official certification manuals. Inclusion criteria required documented design targets and post-occupancy outcomes for certified buildings (2014–2024). A two-phase analytical model was applied: first, evaluating each system’s structure and priorities; then benchmarking them using the TBL framework to assess how holistically each addresses sustainability. Results show that LEED leads to energy optimization, BREEAM to lifecycle integration, and WELL to occupant health and indoor environmental quality. However, all systems exhibit post-occupancy performance gaps: LEED and BREEAM underperform by 15–30% in energy use, while WELL-certified projects may exceed 30% due to stringent indoor comfort demands. These findings highlight the need to integrate real-time post-occupancy evaluation into certification protocols. To improve overall effectiveness, the study proposes enhancements such as adaptive performance tracking, occupant feedback loops, and dynamic benchmarking aligned with actual building use. By identifying both the comparative strengths and systemic limitations of the three frameworks, this research contributes to the refinement of green building assessment tools. Practical implications include (1) integrating post-occupancy evaluation into certification renewal cycles, (2) adopting hybrid certification strategies to improve sustainability coverage, and (3) designing benchmarking tools that reflect real-world operational data.

Contemporary construction faces the need to reduce its negative impact on the environment, prompting designers, investors, and contractors to seek more sustainable materials and technologies. One area of dynamic development is the use of natural fibers as an alternative to conventional, often synthetic, building components. Plant- and animal-based fibers, such as hemp, flax, jute, straw, bamboo, and sheep’s wool, are characterized by low energy consumption in production, renewability, and biodegradability. Their use is in line with the concept of a circular economy and reduces the carbon footprint of buildings. Natural fibers offer a number of beneficial physical and functional properties, including good thermal and acoustic insulation parameters, as well as hygroscopicity, which allows for the regulation of indoor humidity, improving air quality and comfort of use. In recent years, there has also been a renaissance of traditional building techniques, such as straw construction, often combined with modern engineering standards. Their potential is particularly recognized in green and energy-efficient construction. The article provides an overview of the types of natural fibers available for use in construction and analyzes their technical, environmental, and economic properties. It also draws attention to current regulations, standards, and certifications (e.g., LEED, BREEAM) that promote the popularization of these solutions. In light of the analyzed data, the role of natural fibers as a viable alternative supporting the transformation of the construction sector towards sustainable development is considered. Full article

BREEAM (Building Research Establishment Environmental Assessment Method) is widely recognized for promoting environmental sustainability in the built environment, with a strong focus on energy efficiency, resource management, and ecological impact. However, as sustainability entails environmental and economic dimensions but also social dimensions, the current BREEAM New Construction standards do not fully address social sustainability targets. This article explores the potential for expanding BREEAM New Construction standards to more comprehensively incorporate social sustainability, ensuring that certified projects contribute to the well-being of their occupants and surrounding communities. Through a review of existing BREEAM categories, technical manuals, standards, and an analysis of gaps related to social sustainability, this paper identifies key areas for potential improvement, including user satisfaction, protecting workers’ and human rights, legacy planning, education and skills, and emergency response planning. These gaps are mapped against existing BREEAM categories and credits, with recommendations to introduce additional credits across the categories of management, materials, energy, waste, land use and ecology, health and well-being, and water. Additionally, this paper highlights the importance of transdisciplinary collaboration—bringing together architects, urban planners, social scientists, and public health experts—to effectively address the complexity of social sustainability in building design and certification. The proposed additions to BREEAM New Construction standards, alongside recommendations for industry and policymakers, offer guidelines for the evolution of green building certifications toward a more holistic approach to sustainability. This shift ensures that future certified buildings reduce environmental impact and promote social equity, health, and community well-being simultaneously. Full article

This study examines the quality and availability of daylight in childcare facilities, focusing on compliance with Polish Technical Conditions (TCs) and comparing them with international certification systems such as BREEAM, LEED, and WELL. Polish regulations regarding sunlight exposure require revisions to support the sustainable development of buildings, impacting children’s well-being, their health, and the building’s energy efficiency. Daylight’s significance for children’s health and development underpins the investigation, highlighting its impact on the circadian rhythm, cognitive abilities, and well-being. The research utilized computational simulations with Rhinoceros 7 and Ladybug and Honeybee plugins to model a preschool room’s daylight performance under various window configurations and orientations. Quantitative and qualitative analyses were conducted, focusing on parameters such as Daylight Factor (DF), Daylight Autonomy (DA), and Useful Daylight Illuminance (UDI). The findings revealed that while the TCs’ requirements ensure minimum daylight access, they result in nonoptimal lighting quality as defined by international standards. Almost half of the surveyed rooms in the case with a WFR of one-eighth did not meet the condition for having acceptable daylight levels, as defined in the study. In the same study, only about one-third of the analyzed variants achieved the threshold for good daylight quality. At a WFR of one-eighth, no room variant reached the level considered to indicate excellent daylight quality. The results show the need for revised regulations incorporating comprehensive metrics like Climate-Based Daylight Modeling (CBDM). This study suggests that integrating advanced methods of assessing daylight quality could significantly improve daylight conditions in childcare environments. This research is a starting point for discussing the need to modernize the Polish Technical Conditions (TC) to support the sustainable development of childcare facilities in Poland. Full article

This study examines the influence of sustainability certifications on the real estate market, particularly highlighting the advantages they offer compared to uncertified buildings and their recognition within the industry. A survey targeting various industry professionals garnered ninety responses, predominantly from the real estate sector. The survey explored the respondents’ awareness and perceived benefits of sustainability certifications, their priority areas within sustainability, and the relevance of these certifications across different real estate sectors. The analysis also compared the additional costs and operational savings of certified versus uncertified buildings. Among the certifications, LEED and BREEAM were the most recognized. The primary benefits associated with these certifications included enhanced corporate image, improved health and well-being, increased building value, and higher rental yields. We estimated a valuation and rent premium for certified buildings, noting that these premiums were more pronounced among respondents who were younger, had less professional experience, and were from the property sector. The office market was identified as the segment placing the highest importance on sustainability certifications. Additionally, the LiderA evaluation system’s weighting closely aligned with the respondents’ sustainability priorities. This study concludes that while sustainability certifications incur a cost premium, this is outweighed by the appreciation in building value, rental advantages, and operational cost savings.
