Mainland Portugal presents an extensive, diversified and complex coastal zone. This diversity gives rise to diverse geomorphologic features which support different densities of human occupancy and a range of land uses and activities. In this sense, the coastal zone becomes an area of great national strategic value, but has also into a multi-hazard zone. To understand this complexity, two statistical techniques, namely Cluster Analysis and Principal Component Analysis, were used to identify and differentiate, between the different coastal typologies, based on a set of variables that express the territorial complexity and the occurrences and impacts of coastal flooding. The chosen methodology enabled a diverse set of coastal typologies to be identified, which contributes towards differentiating local specific characteristics. The holistic and differentiating nature of the applied methodology and the results obtained allows it to contribute to the definition of mitigation strategies and the implementation of adaptation measures. The results enable us to define a set of typologies associated with Coastal Disaster Risk Reduction and Management which are an important contribution to comprehensive coastal flood risk assessment and management.

Fires in tunnels are a major concern due to the casualties they may cause. Therefore, forcedventilation is mandatory in long tunnels, despite the significant associated costs. In shorter tunnels,however, natural ventilation may be sufficient to comply with safety regulations. Accordingly, theanalysis of natural fire smoke flow is relevant for tunnels shorter than 1000 m. This paper presentsa computational investigation of the influence of the tunnel slope on the contamination of the coldlower layer with smoke and discusses how it impairs the user

The increasing demand for the development and expansion of transport infrastructuresrequires alternative solutions that are economically and environmentally viable to providethe necessary raw materials. Transport infrastructures consume a large amount of naturalaggregates; however, from a circular economy perspective, industrial by-products can effec-tively replace these materials. This avoids the environmental impacts associated with the ex-traction of natural raw materials and simultaneously provides a destination for the industrialby-products. For this purpose, it is important to evaluate if existing standards and technicalrequirements that were developed for natural aggregates are suitable for industrial by-prod-ucts. This review study is focused on slags from steelmaking process in electric arc furnaces,which are generally of two types: oxidizing (black colored) and reducing (lighter colored), spe-cifically addressing the requirements of these materials for the granular layers of transportinfrastructures. The chemical composition of the slags is analyzed as well as its physicaland mechanical characteristics, swelling behavior, and leachate content, discussing testing pro-cedures and technical specifications.

To reach European climate neutrality by 2050, the strategic importance of retrofitting the existing building stock is clear. For this scope, thermal rendering systems have emerged as a very feasible solution for historic and traditionally constructed walls. Nonetheless, a definitive guideline for the selection of suitable solutions for the application in this context is not yet available. This research aims at providing recommendations for the choice of hygric-compatible solutions in an early-stage design, for the context of temperate climates with mild winters. In this study, the massive masonry walls of three historic buildings located in Portugal and Italy are considered. Mono-dimensional hygrothermal simulations are validated against the data measured on-site. Simulations are then used to evaluate the impact of thermal renders on the walls, in comparison to more common insulation materials. Two moisture-related risks are considered: moisture accumulation and reduction of drying. This investigation shows that, for traditional porous walls, retrofitted configurations should be simulated not only under typical operational conditions but also considering a very high initial water content in the wall substrate, when the insulation is applied. Otherwise, moisture-related risks may be overlooked. Recommendations on the choice of thermal rendering systems are provided.

Depois de se apresentarem algumas notas introdutórias ao presente conjunto de artigos sobre habitação intergeracional avança-se para a temática direcionada para o privilegiar do desenvolvimento de tipologias residenciais etariamente dirigidas, repartindo-se a matéria em duas partes: uma delas ligada à renovação tipológica residencial numa fase tardia da nossa vida e a outra ao desenvolvimento de tipologias e soluções para habitações amigas dos idosos, numa reflexão ainda de enquadramento.A primeira parte aborda sequencialmente a questão do como habitar melhor numa fase tardia da nossa vida e, depois a relação entre a renovação tipológica habitacional e a atual

Depois de se apresentarem algumas notas introdutórias ao presente conjunto de artigos sobre habitação intergeracional avança-se na matéria das respetivas tipologias residenciais, agora, de uma forma mais ligada à prática, iniciando-se, especificamente, o artigo com uma abordagem de soluções mais correntes e naturais de intergeracionalidade residencial, neste caso referidas à prática da coabitação, seguindo-se um avanço nas soluções de

The identification of the main degradation agents and knowledge of the degradation mechanisms and long-term performance of ETICSs are of fundamental importance for the sustainable and efficient use of these systems. This review article presents the state of the art related to the durability of ETICSs, defining the required bases for their sustainable and efficient use. The aim is to identify the most common anomalies detected on ETICS façades and their causes, to overview the performance of ETICS, their performance parameters and requirements and to identify the most significant degradation mechanisms and the related failure modes. The results show that ETICS application is a key aspect in the performance and durability of the system, since most of the anomalies can be prevented with proper design, execution and appropriate assembly of the system components. The greatest drawbacks lie in dealing with enhancing the water resistance over time, which leads to extensive cases of anomalies, and improving the mechanical and thermal performance during the life cycle. Further research is needed to evaluate the synergistic effect of several degradation agents and mechanisms toward a development in optimized durability assessment methodologies for ETICSs.

Few scientific publications discuss the vision of the water-smart society. Our paper addresses this gap, outlining key principles of urban water

Major strategic investments in infrastructures and equipment across four different areas have been outlined by the National Investments' Program (PNI 2030) in Portugal. This paper is built on the environmental assessment study of the PNI 2030 and focus on its key methodological contributions and policy recommendations addressing the transport and mobility area that represents around 52% of the total investment. One innovative feature of the study is the multi-level system of indicators' framework developed to assess and monitor impacts along time, within the scope of the five "Critical Decision Factors", namely "Climate change and energy transition for decarbonisation", "Territorial cohesion,mobility and accessibility", "Competitiveness and innovation". Finally,the set of policy recommendations to promote a better incorporation of environmental and sustainability issues are outlined.
