Due to its intricate production processes, complex supply chains, and industry-specific characteristics, the construction industry faces unique challenges in adopting circular economy (CE) principles that promote resource equity. To address this issue, this study aims to delve into identifying stakeholders’ opinions and perceptions regarding key CE strategies across different stages of the building life cycle (BLC). Both European and non-European stakeholders within the “CircularB” COST Action network and beyond participated in this research. Three methods were employed to assess stakeholders’ opinions: an online survey, a structured survey with a semi-guided workshop, and creative thinking round table discussions. Natural language processing (NLP), specifically topic modelling and sentiment analysis, was used to analyse the data collected from the online survey, which gathered text-based opinions from 209 participants on the cost-benefit aspects of circularity strategies. The structured survey, which collected data from 43 workshop participants, evaluated the perceived importance of CE strategies across various BLC phases and assessed the adoption of selected CE strategies in current or past projects. Finally, the Six Thinking Hats® activity, employed in the round table discussions, generated ideas from 25 professionals regarding the broader implementation challenges and opportunities of CE in construction. The research findings highlight the need to bridge the gap between theory and practice by fostering active industry stakeholder involvement in the transition to a CE model. The analyses of the collected stakeholder opinions through the three activities contribute to proactive and collaborative efforts aimed at advancing resource equity in the construction sector and promoting just and inclusive resource use. In summary, this research offers a comprehensive understanding of stakeholders’ opinions on CE strategies and provides guidance for the development of targeted policies and strategies to accelerate the integration of CE principles in the construction industry.

Penalty saves in football are crucial for determining match outcomes and are widely acknowledged as one of the most intense and demanding situations in the sport. Goalkeepers face the formidable challenge of interpreting opponents' cues and responding effectively to prevent goals during penalty kicks. This study aims to rigorously analyse the various factors influencing goalkeepers' success in defending penalty kicks. Data on penalty kicks from prestigious international competitions, specifically the UEFA Europa League and UEFA Champions League, were systematically collected for the period between 2018 and 2022. A representative sample of 103 penalty kicks taken during these matches was selected for comprehensive analysis. The assessment of goalkeepers' influence on penalty kick saves considered previous defensive statistics and relied on three main factors: preferred side (the direction where they have a greater tendency to move for a save), reading ability (anticipating the ball's trajectory based on opponent analysis, such as posture and gaze direction), and reaction speed (the ability to respond to the shot). The results showed an average save rate of 22.3%, with a considerable range spanning from 9.8% to 38.8%. Regarding defensive tendencies, 54.5% of goalkeepers displayed a preference for the right side. Importantly, goalkeepers who instinctively moved towards their preferred side first achieved a significantly higher success rate of 65.3%. The average reaction speed among goalkeepers was measured at 0.37 seconds. A statistically significant negative correlation (r = -0.76, p < 0.001) was observed between reaction speed and defence rate, underscoring that faster reactions enhance the likelihood of successful defence. Furthermore, goalkeepers with a greater ability to anticipate ball trajectories demonstrated higher defence rates. Effective penalty kick defence in football relies on rapid responses, anticipation of ball trajectories, and goalkeepers' proclivity to move towards their preferred side as a primary instinct. Strategic planning and specific skills training significantly impact goalkeepers' performance by incorporating visual reaction exercises, agility, and coordination training and utilising visual resources such as real penalty kick videos. Advanced technologies like data analysis and artificial intelligence offer detailed feedback and cognitive training to improve decision-making. Enhancing diving technique, positioning, and practising various penalty kick angles and trajectories are crucial for technique and coordination. These scientifically supported approaches form a strong basis for future research and training interventions, aiming to enhance goalkeepers' defensive abilities in penalty kicks.

Despite state efforts to enhance affordability, access to adequate housing, deemed a fundamental human right, remains a global challenge. Projections indicate a looming housing deficit affecting 1.6 billion people by 2025, necessitating an integrated approach aligning environmental preservation with housing development. Circular Economy (CE) principles are identified as instrumental in advancing sustainable Social Housing Policies (SHPs). A Systematic Literature Review (SLR) placed best practice documents establishing a positive correlation between CE principles and increased social housing supply. The circularly built environment is recognised for reducing waste, carbon emissions, and resource depletion. However, this research proposes a nuanced perspective, asserting that integrating CE principles addresses housing needs and fosters environmental sustainability, job creation, and economic growth. Crucially, community, government, and the circular economy emerge as pivotal actors in overcoming challenges inherent in SHPs. This study contributes significantly to the discourse on housing policies and sustainability, advocating for an inclusive and environmentally conscious approach to the global housing deficit.

This research explores sustainable construction practices focusing on material reuse, specifically reclaimed structural steel and slag. In general, the building stock is not designed for deconstruction, and material recovery for reuse at the end of life of buildings is complex and challenging. The study evaluates the benefits of content reuse through a thorough analysis of three case studies—BedZED eco-friendly housing, Angus Technopôle building, and the use of steel slag aggregate in road construction. It highlights the value of reclaimed structural steel and by-products like steel slag in waste reduction, energy conservation, and resource preservation. The BedZED case study showcases recycled steel’s cost-effectiveness and economic viability in construction, while the Angus Technopôle building exemplifies the adaptive reuse of an old steel frame building. Additionally, the third case study showcases the benefits of using Electric Arc Furnace C slag in asphalt-wearing courses, highlighting the reduction in greenhouse gas emissions and environmental impact. The versatility of reclaimed structural steel and slag is evident in integrating material reuse in building construction and road infrastructure. These case studies illustrate the potential for reusing steel and its by-products in various construction contexts, from eco-friendly housing to road development. Therefore, the study aims to demonstrate the feasibility and benefits of sustainable practices within the construction industry by showcasing the successful incorporation of reclaimed steel and slag in these projects. Considering the significant contributions of building construction to global greenhouse gas emissions, raw material extraction, and waste production, the study advocates for adopting circular economy (CE) principles within the construction industry. Finally, the analysis of case studies underscores the advantages of reclaimed structural steel and the valorisation of steel slag through the lens of CE and their contribution to sustainable development.

The construction sector stands as the predominant consumer of cement, steel, and plastic and is accountable for a substantial 55% of industrial carbon emissions. Greenhouse gases and other forms of pollution linked to the housing sector significantly contribute to the adverse environmental impact of the construction industry. This study underscores the need to incorporate pertinent issues into the Circular Economy (CE) agenda for a lasting and effective mitigation strategy. Through a Systematic Literature Review (SLR), this article explores answers to the research question: “How can the Circular Economy contribute to resolving social housing challenges?” The findings from this comprehensive review highlight that refurbishing the social housing (SH) built environment and formulating public policies targeted at the SH sector emerge as pivotal themes for effective solutions. The principles of the Circular Economy present a sustainable model that can play a crucial role in addressing the social housing challenge. In conclusion, this SLR demonstrates that Circular Economy principles offer a viable approach to tackling the social housing crisis. By embracing these principles, a sustainable model can be established to address the challenges posed by social housing, thereby contributing to the broader goal of environmental conservation in the construction sector.

Building construction accounts for a significant proportion of global greenhouse gas emissions, raw material extraction, and waste production. Applying circular economy (CE) principles in the building construction industry would considerably reduce these values. However, uptake by the industry is relatively slow, which is largely attributed to sectoral barriers, including limitations in knowledge and experience. This review paper aims to assess and contribute to diminishing these obstacles by offering a comprehensive review of circular material usage principles and strategies within the construction sector. Opportunities and facilitators of change are also presented, including innovations and emerging technologies in recycling, digitization, robotic systems, novel materials, and processing. Finally, four case studies demonstrate the application of circular theory via a novel block system, recycled aggregate, modular kitchen reuse, and an energy efficiency retrofit. The conclusions show that future efforts should prioritize the development of strong regulatory frameworks, awareness initiatives, and international cooperation. In this regard, the integration of technological advancements, such as AI, robotics, and blockchain, is essential for optimizing waste management efficiency. Furthermore, education on circular practices plays a critical role. Through global collaboration, standardizing circular construction approaches can promote a more sustainable and resilient building construction industry.

This article presents a literature review of Transition Experiments applied to the Sustainable Urban Mobility context from a critical and operative point of view. The moment of transformation that we are living through determines concerns about the decarbonization and compliance with the 2050 Targets and imposes a paradigm shift towards sustainable urban mobility. In this regard, the necessary physical change will have to be accompanied by a socio–cultural transition, of which the challenge implies the construction of a collective ideal, shared by the population and the main stakeholders, leading to the opening of new political spaces and a change, also in terms of governance.

According to the European Green Deal, excessive carbon emissions are the origin of global warming and must be drastically reduced. Given that the building sector is one of the major sources of carbon emissions, results imperative to limit these emissions, especially in a city context where the density of buildings is commonly higher and rapidly increasing. All stages of the life cycle of a building, including raw material harvesting, manufacturing of products, use phase of the building, end of life, all generate or reduce carbon. The manufacture of construction materials accounts for 11% of all energy and process-related emissions annually. Additionally, recent estimates indicate that over 80% of all product-related environmental impacts of a building are determined during the design phase of the building. These indicators reflect the urgent need to explore a low-carbon measure method for building design. This is here done using a linear regression Reverse Engineering model and percentage calculation. One of the hypotheses formulated relates Global Warming Potential (GWP) of −30.000 CO2eq or lower (around −165 CO2eq/m2) in the 25% of a block of houses, to carbon further reductions by 11%. This paper has identified barriers in terms of the databases needed to achieve this task.

Sustainability assessment methods have gained the attention between urban planners and policymakers since they promote a comprehensive view of the cities. Intelligent solutions, enabled by advances in information technologies, can accelerate progress in achieving sustainability goals. In this context, City Information Modelling (CIM) emerges as a tool to facilitate urban sustainability assessment implementation. Accordingly, the main question aimed to address in this article is whether conventional sustainability assessment tools can be adapted to the CIM framework. In this regard, this study extracts the most consensual list of indicators from four sustainability assessment methods: BREEAM-C, LEED-ND, SNTool, and SBToolPT Urban, to identify a clear set of key sustainability priorities. The selected sustainability assessment methods are pioneering and often used for performance assessment at the urban scale. Furthermore, the indicators extracted from the assessment methods are measurable and can present accurate results. The study analyses the potential of the selected indicators to be calculated in CIM. The final product of the article is identifying the indicators that are adaptable to be used in the CIM approach.

Urban planning is a valuable tool for growth control and city development, both to maintain the local urban identity and provide life quality for inhabitants. To regulate it, local governments have defined standards for a proper city’s growth through municipal and detailed urban plans. Such instruments identify a set of rules which constructions and buildings must fulfil for a careful and smooth integration within the urban areas. New projects are required to comply with such rules, and designers must adapt and guarantee that their projects fulfil all the local urban requirements. However, the verification process of construction projects is still a manual procedure and often a time-consuming process, with high possibilities for inaccurate measures. Thus, this paper aims to streamline the verification procedure of construction projects’ code compliance to enhance project design efficiency and save designers time. To do so, the Building Information Modelling (BIM) method will be used through the Dynamo programming software. By creating a Dynamo routine to check the building code and urban plan compliance from Brazilian municipalities, specific BIM models will be automatically analysed to detect and evaluate if it is according to local urban legislation. Results have provided a real-time decision support tool, where designers can assess if their buildings are complying with local urban codes at any time of the design stage, making it easy to innovate and integrate innovative design options, as well as to precisely communicate their buildings’ code compliance. Such a method can also support municipality authorities to verify project compliance, reducing assessment and calculation errors, as well as the required time and bureaucracy for project appraisal.

The concept and practice of sustainability in urban planning have gained worldwide significance since the early 2000s and have become increasingly mainstream in the policymaking process. Adopting global frameworks, such as the United Nations Sustainable Development Goals and ISO standards, for sustainable communities provides an opportunity to build more sustainable, innovative, and equitable towns and cities, with regard to natural resources and biodiversity. However, attaining sustainability requires addressing many fundamental issues at various levels, and achieving the goals and objectives of sustainability poses a significant challenge for all segments of society. Several methods for assessing the sustainability of the urban environment have been established in recent years. Therefore, compiling a short and comprehensive list of indicators addressing the broad concept of urban sustainability issues has arisen as a significant challenge. This research reviews four urban sustainability assessment tools—BREEAM-C, LEED-ND, iiSBE SBToolPT Urban, and iiSBE SNTool—to identify a clear set of key sustainability priorities. This study aims to highlight a more consistent list of indicators that are considered the most significant aspects and priorities within the analysed sustainability methods, allowing for a common understanding of the most important principles that must be considered in the design of sustainable urban areas and are compatible with the most recent standardization and sustainability targets. The end product of this study includes a proposal for a set of sustainability indicators to assess environmental, social, and economic issues to implement in the design of sustainable urban environments, independent of the local context.

A growing interest has been expressed in the issue of building adaptability over the past decade, perceiving it as an intrinsic criterion for sustainability. In light of the circular economy (CE) and its application in the construction sector, more attention has been paid to buildings’ design for adaptability (DfA) towards the realization of circular buildings. DfA is considered a key enabler for other circular design strategies such as design for disassembly (DfD), multi-functionality, spatial transformability, and design reversibility. However, implementation and assessment frameworks, and design-support tools for the circular building, are still in development as the characterization of circular buildings continues with endeavors to draw a defined shape by identifying the prerequisites for circularity where the design takes an important place. For the sake of objectifying the role of DfA in circularity frameworks in buildings, this paper carries out an analytical review and discussion on two types of assessment and design-support frameworks; the first addresses adaptability criteria and considerations in assessment frameworks that handle the concept individually while the second classifies existing circularity assessment endeavors into four main categories under which multiple tools are reviewed. A reflection on the scope and objectives for both types is later performed, illustrating the state of adaptability evaluation and criteria as well as its role in circularity frameworks. Results show that the concept of building adaptability lacks quantitative methods that quantify a building’s capacity to adapt as well as empirical data that prioritize the most valuable criteria facilitating adaptations. Moreover, many circularity assessment frameworks fail to consider adaptability criteria at all hierarchal levels of a building composition. To address this shortcoming, a series of conceptual considerations and requirements is proposed towards a potential establishment of an inclusive framework of a circularity design-support tool in buildings. The study is concluded by identifying gaps and recommendations for further developments in the field.

Climate change has a strong influence on the energy consumption of buildings, affecting both the heating and cooling demand in the actual and future scenario. In this paper, a life cycle assessment (LCA) was performed to evaluate the influence of both the occupant behaviour and the climate change on the environmental impact of the heating and cooling systems of an apartment located in southern Italy. The analysis was conducted using IPCC GWP and ReCiPe indicators as well as the Ecoinvent database. The influence of occupant behaviour was included in the analysis considering different usage profiles during the operational phase, while the effect of climate change was considered by varying the weather file every thirty years. The adoption of the real usage profiles showed that the impact of the systems was highly influenced by the occupant behaviour. In particular, the environmental impact of the heating system appeared more influenced by the operation hours, while that of the cooling system was more affected by the natural ventilation schedules. Furthermore, the influence of climate change demonstrated that more attention has to be dedicated to the cooling demand that in the future years will play an ever-greater role in the energy consumption of buildings.

Buildings are responsible for several negative impacts on the environment, most of them related to nonrenewable energy consumption, increasing the concern regarding buildings energy efficiency. In this context, computer software has been used to estimate the energy needs of the built environment, and the Building Information Modelling (BIM) methodology can be used to simplify this process. This study aims to validate a BIM-based framework to streamline the energy analysis of Portuguese buildings, based on the method of the national regulation for the thermal performance of residential buildings. Currently, designers need to spend considerable time assessing all the building characteristics and performing the mandatory calculations for energy performance analysis. It is also intended to link the results of the energy simulation with a Building Sustainability Assessment method—SBToolPT-H. The purpose is to demonstrate how it is possible to benefit from this approach to simultaneously improve building sustainability during the design stage. To do so, different case studies were modelled in Autodesk Revit and exported to a BIM energy tool to perform energy simulation analysis. The results were validated against the official assessment method of the Portuguese thermal regulation and were successfully used to assess the SBToolPT-H energy efficiency category. The research outcomes provide design teams with a reliable BIM-based framework to improve building energy performance and to develop thermal projects while enhancing building sustainability. It also increases the knowledge about the integration of sustainability assessment in the BIM environment, providing new insights for complete integration.

Our ever-evolving built environment is continuously facing emerging needs for housing, work, health, and mobility, among others. Yet, buildings are usually designed and set up as finished permanent objects, reflecting the one constant scenario in mind of defined form, function, and performance. Since change is increasingly inevitable in our life, enlarging buildings’ adaptive capacities in response to arising variables and changing conditions over their lifecycle becomes a necessity in seeking global sustainability demands. The concept of building adaptability has been a notable subject in this respect, increasingly stimulating and proposing regenerative alternatives to today’s often obsolete buildings. This paper critically reviews the existing body of knowledge on the concept of adaptability in building research. The main focus is made on the evolution of the concept interpretations and related paradigms, and on the development of its applications and strategies in the light of promoting models and trends. Drawing on the literature as a source of evidence, the paper analyzes and classifies the content of existing studies published in scientific journals and gray literature, focusing on a timeframe from 2015 up-to-date. Moreover, the paper aims to build a constructive discussion to identify potential gaps between the actual state of the art and emerging needs, which should be addressed by further research.

Population growth, along with a rapid urban expansion, is imposing a heavy pressure on the planet’s finite resources. It is widely acknowledged that the building industry consumes large amounts of raw materials while generating waste and emissions. To set apart economic growth from environmental repercussions, the Circular Economy (CE) arose as an innovative paradigm that can offer a fast-track towards a sustainable built environment. This paper will tackle a research gap that academia and policymakers often highlighted, which is how can we apply CE to assets that are predominantly meant to be demolished and their resources wasted when they reach their end-of-life. Globally, the paradigm aims at erasing the waste concept, relying on renewable and regenerative sources, and keeping the materials, components, and systems in use at their highest value as long as possible. The concept’s implementation would attempt to consider the built environment as a closed-loop system wherein resources are viewed as a scarce commodity. Although the CE seems straightforward, translating the circular thinking to the building level might be a hardship. The following paper will attempt to shed light on how to promote CE in buildings that will ultimately lead to healthier, more efficient, and more sustainable cities on a broader scale. The proposed framework considers CE implementation strategies throughout the building’s lifecycle and mainly deals with three innovative aspects: wise resource management, building design approaches, and digitalization of the building industry. In this sense, this study will explore these game-changing factors that are considered paramount to concretize the concept in practice and provide a smooth pathway for CE uptake in buildings.

A growing concern is given to the environmental impacts caused by the construction industry. Waste generation, resource consumption, and greenhouse gas emissions are the main drawbacks of the rapid urbanization that the world is witnessing. As a response to these pressing issues, policymakers and academia are exploring the concept of Circular Economy (CE) to manage resources better and achieve resource efficiency while eliminating waste. One of the strategies to implement CE in the built environment is to select the appropriate building materials and components from the early stages to carry out the concept’s principles along the value chain and create a closed-loop system. Therefore, this study aims at identifying selection criteria for building elements according to CE principles through a review of the latest research. Results have shown that little has been concretely achieved in terms of a paradigm shift to CE since the main focus of the literature is still the use of recycled products and the recyclability of building materials and components at their end-of-life. Although the present study is solely focused on the technical aspect of building materials and components, it outlines current adopted criteria to bring about a circular built environment and highlights the need for a more innovative approach to attain higher circularity levels.

Energy performance of buildings is a worldwide increasing investigated field, due to ever more stringent energy standards aimed at reducing the buildings’ impact on the environment. The purpose of this paper is to assess the impact that occupant behavior and climate change have on the heating and cooling needs of residential buildings. With this aim, data of a questionnaire survey delivered in Southern Italy were used to obtain daily use profiles of natural ventilation, heating, and cooling, both in winter and in summer. Three climatic scenarios were investigated: The current scenario (2020), and two future scenarios (2050 and 2080). The CCWorldWeatherGen tool was used to create the weather files of future climate scenarios, and DesignBuilder was applied to conduct dynamic energy simulations. Firstly, the results obtained for 2020 demonstrated how the occupants’ preferences related to the use of natural ventilation, heating, and cooling systems (daily schedules and temperature setpoints) impact on energy needs. Heating energy needs appeared more affected by the heating schedules, while cooling energy needs were mostly influenced by both natural ventilation and usage schedules. Secondly, due to the temperature rise, substantial decrements of the energy needs for heating and increments of cooling energy needs were observed in all the future scenarios where in addition, the impact of occupant behavior appeared amplified.

The sustainability potential of Brazilian social housing (SH) needs to be assessed, considering the impacts on the population’s quality of life and urban systems. One of the main weaknesses of Casa Azul Label refers to the absence of a procedure that quantifies the measures for assessing urban sustainability. Based on the post-occupation analysis of an SH project implemented in Araraquara, São Paulo state, Brazil, evaluation of urban sustainability was developed, using a multi-method approach combining the Casa Azul Label and Sustainable Building Tool (SBTool) Urban certification tools. It was proposed to apply the calculations established in SBTool Urban according to the Casa Azul Label certification requirements, as well as insert a national benchmark as a reference for the analysis and normalizing results. These procedures made it possible to base an improvement framework on a Brazilian environmental certification system, including a quantification system to evaluate the efficiency of the applied measures regarding urban sustainability. The multi-method approach, associated with the SBTool Urban procedures, could significantly help to improve the application of a sustainable assessment system in social housing in developing countries. The high number of residential units produced in recent years could be qualitatively evaluated, improving both the construction procedures and the criteria for the urban insertion of human settlements.

Building Information Modelling (BIM) is creating new opportunities for the Architecture, Engineering and Construction industry. One of them is the integration of the Building Sustainability Assessment (BSA) during the design process. Currently, an approach for using BIM to foster and optimise the application of BSA methods has not been clearly established yet, creating a knowledge gap on the application of BIM for sustainability assessment purposes. Thus, this paper analyses the current role of BIM to evaluate three BSA methods—LEED, BREEAM and SBTool. The current BIM applicability is assessed by performing a systematic review, where the criteria being assessed and the applied BIM software are identified. A comparison is made to determine which BSA method can currently take more advantage from BIM and to identify the number of assessed criteria from each one. Furthermore, the attractiveness of a BIM-based assessment for SBTool is analysed, facing the actual BIM scenario for LEED and BREEAM. Despite the restrictions, BIM use is increasing for sustainability purposes. Most of the analysed studies and identified software are still focused on the use of LEED for assessing sustainability during the design phase. However, BIM software capabilities can also support the assessment of the other BSA methods so that process replicability can happen. Among the most addressed criteria, the energy and material-related categories are the most eminent. Autodesk Revit is the most-used software. A BIM-based assessment for SBTool will have enough attractiveness. It can assess, at least, the same percentage of criteria as the other schemes, creating new opportunities to enhance building sustainability.

Solar passive strategies that have been developed in vernacular architecture from different regions are a response to specific climate effects. These strategies are usually simple, low-tech and have low potential environmental impact. For this reason, several studies highlight them as having potential to reduce the demands of non-renewable energy for buildings operation. In this paper, the climatic contrast between northern and southern parts of mainland Portugal is presented, namely the regions of Beira Alta and Alentejo. Additionally, it discusses the contribution of different climate-responsive strategies developed in vernacular architecture from both regions to assure thermal comfort conditions. In Beira Alta, the use of glazed balconies as a strategy to capture solar gains is usual, while in Alentejo the focus is on passive cooling strategies. To understand the effectiveness of these strategies, thermal performances and comfort conditions of two case studies were evaluated based on the adaptive comfort model. Field tests included measurement of hygrothermal parameters and surveys on occupants’ thermal sensation. From the results, it has been found that the case studies have shown a good thermal performance by passive means alone and that the occupants feel comfortable, except during winter where there is the need to use simple heating systems.

A utilização de materiais de isolamento térmico para a obtenção de edifícios energeticamente eficientes visa, na generalidade dos casos, a satisfação das respetivas necessidades de aquecimento e arrefecimento da fase operacional. O objetivo principal deste trabalho é o de - mediante a utilização de metodologia exploratória, nomeadamente revisão bibliográfica - identificar materiais de isolamento mais sustentáveis e, concomitantemente, expor o efeito paradoxal de outros com elevado Potencial de Aquecimento Global (GWP), destacando o papel da Avaliação de Ciclo de Vida (ACV), do Ecodesign e da Declaração Ambiental de Produto (DAP) para a conceção, comparação e seleção de materiais. Como principal conclusão, salienta-se a ausência generalizada de informação ambiental por parte dos produtores o que, a par de preços de aquisição que não internalizam Custos de Ciclo de Vida (LCC), tem conduzido à utilização de materiais com elevada pegada de carbono e ao “paradoxo do isolamento”.

The European Union objectives in the Horizon 2020 program aim to reduce environmental impact through strategies such as the improvement of energy efficiency and the use of renewable technologies. With regard to the goal of sustainable development—which integrates environmental, social, and economic dimensions relating to the preservation of the planet and the integrity of consumers—several types of sustainability certification tools are currently used in the construction industry e.g., Leadership in Energy and Environmental Design (LEED), the Building Research Establishment Environmental Assessment Method (BREEAM), and the Sustainable Building Tool (SBTool) There are international sustainability methodologies designed specifically for high schools and methodologies specific to the Portuguese reality, such as Natura Domus, LiderA (Liderar pelo Ambiente para a construção sustentável, Leading the Environment for Sustainable Construction) and SBtoolPT (Sustainable Building Tool, Portugal). Currently, with the concern in Portugal to requalify schools, it has become necessary to develop a specific methodology for school buildings according to the Portuguese reality. This work highlights the SBTool methodology that is employed in several countries and can be adapted to basic education institutions as the basis for the formulation of responsible citizens and the development of a country. The main aim of this study is to adapt an already existing assessment tool of sustainability (SBToolPT), maintaining some indicators while modifying and adding others, in order to develop a methodology specifically for conducting a Sustainability Assessment of High School Buildings in Portugal—SAHSBPT. In order to achieve this goal, other methodologies that already incorporate parameters relating to the school environment are analyzed, such as LEED BD + C Schools (LEED Building Design and Construction School), BREEAM Education 2008, and the SBTool for K−12 schools.

O projeto de um ambiente hospitalar requer uma série de preocupações com a satisfação e bem- estar da equipa de trabalho, pacientes e administradores, ao mesmo tempo que possui uma forte responsabilidade social e impacte na cidade. Atualmente, veri ca-se que a maioria deste tipo de edifícios não é concebida ou utilizada de forma sustentável, apesar de já existirem algumas ferramentas que têm vindo a ser desenvolvidas com o objetivo de serem utilizadas no suporte de decisões que permitam otimizar a sustentabilidade dos mesmos. Tendo por base este contexto, o presente artigo tem como objetivos discutir as barreiras existentes na disseminação de práticas sustentáveis nos edifícios de saúde e apresentar uma proposta de estrutura para uma metodologia que, dando resposta a algumas das barreiras identi cadas, facilite a incorporação de princípios de sustentabilidade durante as diferentes fases do ciclo de vida de um edifício hospitalar. A estrutura apresentada é orientada para o contexto português e encontra-se baseada no trabalho desenvolvido até então pelas organizações ISO e CEN e noutras metodologias internacionais de avaliação da sustentabilidade já disponíveis no mercado.

The priorities in the design of more sustainable buildings are quite dependent on the specific social context. In developing countries, the sustainability concept and priorities in the residential buildings sector are quite different from the ones of the developed countries, since there are still basic needs to answer. Therefore, this research is aimed at contributing to a better understanding of the concept of social sustainability in the residential building sector of the developing countries. A methodology to define and prioritise the social sustainability indicators is proposed and applied in the context of Palestine. The presented methodology is based on the sustainability indicators of international standards, on the most well know building sustainability assessment methods and in the analysis of their application to a specific context. It includes a methodology to prioritise the list of social indicators, by considering the expectations of two groups of building stakeholders: designers and building users. At the end, this research proposes a framework of social aspects to consider in the design of more sustainable residential buildings in West Bank, Palestine that is composed of twenty-one indicators, distributed among six sustainability categories and ranked according to their weight in the overall of sustainability level.
