Artículo A novel Index of Vulnerable Homes: findings from application in Spain(SAGE Publications, 2020) Castaño Rosa, Raúl; Solís-Guzmán, Jaime; Marrero Meléndez, Madelyn; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas II (ETSIE)This paper develops a novel index of vulnerable homes in terms of fuel poverty that is based on the analysis of different existing fuel poverty indicators and their relationship to the residential sector. The new index of vulnerable homes unifies the many indicators hitherto employed, and assesses the home vulnerability situation regardless of whether or not it is in fuel poverty by using three dimensions: monetary cost, energy and thermal comfort. The monetary dimension analyses vulnerability in relation to the available net income to face everyday life. The energy variable assesses the vulnerability related to the constructive characteristics of the dwelling. Finally, the introduction of the thermal-comfort variable enables the evaluation of the vulnerability related to the inner temperature of the dwelling and its perception by occupants. The combination of the different resulting values in each dimension and its relationship to the quality of life of occupants establishes a hierarchy of vulnerable levels. As a result, a multi-dimensional index is defined which relates technical aspects (characteristics of the dwelling) and social aspects (quality of life of households). The index of vulnerable homes provides a more complete assessment of the home situation than the existing fuel poverty indicators by identifying which variables require a greater assistance.Artículo Semantic HBIM for heritage conservation: a methodology for mapping deterioration and structural deformation in historic envelopes(MDPI, 2025-06-10) Nieto Julián, Juan Enrique; Robador González, María Dolores; Moyano, Juan; Bruno, Silvana; Universidad de Sevilla. Departamento de Expresión Gráfica e Ingeniería en la Edificación; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas II (ETSIE); Universidad de Sevilla.

TEP172: Arquitectura: Diseño y TécnicaThe conservation and intervention of heritage structures require a flexible, interdisciplinary environment capable of managing data throughout the building’s life cycle. Historic building information modeling (HBIM) has emerged as an effective tool for supporting these processes. Originally conceived for parametric construction modeling, BIM can also integrate historical transformations, aiding in maintenance and preservation. Historic buildings often feature complex geometries and visible material traces of time, requiring detailed analysis. This research proposes a methodology for documenting and assessing the envelope of historic buildings by locating, classifying, and recording transformations, deterioration, and structural deformations. The approach is based on semantic segmentation and classification using data from terrestrial laser scanning (TLS) and unmanned aerial vehicles (UAVs), applied to the Palace of Miguel de Mañara—an iconic 17th-century building in Seville. Archival images were integrated into the HBIM model to identify previous restoration interventions and assess current deterioration. The methodology included geometric characterization, material mapping, semantic segmentation, diagnostic input, and temporal analysis. The results validated a process for detecting pathological cracks in masonry facades, providing a collaborative HBIM framework enriched with expert-validated data to support repair decisions and guide conservation efforts.Artículo Historical "Sebka" Plaster Claddings: Geometric Analysis, Construction Insights, Conservation Status, and Digital Recreation of Polychrome(Taylor and Francis, 2025-07-03) Torres González, Marta; Blasco-López, Francisco Javier; Alejandre Sánchez, Francisco Javier; Universidad de Sevilla. Departamento de Ingeniería Gráfica; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas II (ETSIE); Ministerio de Ciencia e Innovación (MICIN). EspañaHistoric plasterwork façades, particularly sebka panels in UNESCO World Heritage sites such as the Courtyard of the Maidens, represent outstanding examples of Islamic and Mudéjar decorative traditions. Despite their cultural significance, these ornamental claddings are highly susceptible to environmental degradation, structural vulnerabilities, and inappropriate restoration practices. This research adopts an interdisciplinary approach to the preventive conservation of historical plasterwork, combining geometric analysis, environmental monitoring, and material characterisation. Non-destructive techniques, such as infrared thermography (IRT), allowed for the diagnosis of concealed pathologies and construction systems, while XRD analysis provided unprecedented insight into the original polychrome finishes. The study identified typological variations in sebka panels and underscored the role of temperature and relative humidity fluctuations in the mechanical failure of decorative elements, such as pineapples and metal fixings. Crucially, the analysis of the remaining polychromies revealed the original colour palette — featuring azurite blue, vermilion, red ochre, and organic black — thereby recovering the chromatic richness of these unique plasterworks. The outcomes of this research offer innovative preventive conservation strategies and a comprehensive diagnostic methodology that can serve as a reference for the preservation of Islamic-Mudéjar plasterwork in Spain and beyond, ensuring the safeguarding of their material authenticity and artistic integrity.Artículo Thermal comfort in social housing in Ecuador: do free-running buildings work in current and future climates?(MDPI, 2025-06-12) Delgado Gutiérrez, Evelyn Yaneth; Rubio Bellido, Carlos; Canivell, Jacinto; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas II (ETSIE); Ministerio de Ciencia, Innovación y Universidades (MICIU). España; Universidad de Sevilla. RNM162: Composición, Arquitectura y Medio Ambiente; Universidad de Sevilla. TEP211: Conservación Preventiva del Patrimonio ConstruidoEcuador faces a significant housing deficit, prompting government policies aimed at improving access to social housing for vulnerable families. Despite its relatively small geographic size, the country exhibits substantial climatic diversity, encompassing ten distinct Köppen–Geiger climate zones. These range from tropical rainforests to high-altitude Andean regions, each requiring specific housing strategies. However, social housing units are typically designed using a standardized model that disregards regional climatic variations, leading to suboptimal thermal performance and energy inefficiencies. This study evaluates the thermal comfort performance of standardized free-running social housing across six distinct cantons, using the ASHRAE 55-2020 adaptive comfort model. Dynamic simulations were conducted for both current climatic conditions and future scenarios for 2050 and 2100, employing tools such as Meteonorm 8.1 (for weather data), EnergyPlus 9.4.0, and DesignBuilder 7.0 (for thermal modeling). The findings reveal significant differences in indoor comfort levels among identical housing units due to localized climate conditions. Notably, high-altitude regions showed improved thermal performance under future scenarios, whereas coastal lowland areas experienced increased discomfort. These results underscore the urgent need for climate-responsive, adaptive housing designs tailored to local climatic realities across all regions of Ecuador.Artículo StainView: A Fast and Reliable Method for Mapping Stains in Facades Using Image Classification in HSV and CIELab Colour Space(MDPI, 2023-06-01) Torres González, Marta; Valença, Jónatas; Santos, Bruno O.; Silva, Ana; Mendes, Maria P.; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas II (ETSIE); Fundação para a Ciência e Tecnologia (Portugal)The new Construction 4.0 paradigm takes advantage of existing technologies. In this scope, the development and application of image-based methods for evaluating and monitoring the state of conservation of buildings has shown significant growth, including support for maintenance plans. Recently, powerful algorithms have been applied to automatically evaluate the state of conservation of buildings using deep learning frameworks, which are utilised as a black-box approach. The large amount of data required for training, the difficulty in generalising, and the lack of parameters to assess the quality of the results often make it difficult for non-experts to evaluate them. For several applications and scenarios, simple and more intuitive image-based approaches can be applied to support building inspections. This paper presents the StainView, which is a fast and reliable method. The method is based on the classification of the mosaic image, computed from a systematic acquisition, and allows one to (i) map stains in facades; (ii) locate critical areas; (iii) identify materials; (iv) characterise colours; and (v) produce detailed and comprehensive maps of results. The method was validated in three identical buildings in Bairro de Alvalade, in Lisbon, Portugal, that present different levels of degradation. The comparison with visual inspection demonstrates that StainView enables the automatic location and mapping of critical areas with high efficiency, proving to be a useful tool for building inspection: differences were of approximately 5% for the facade with the worst and average state of conservation, however, the values deteriorate for the facade under good conditions, reaching the double of percentage. In terms of processing speed, StainView allows a facade mapping that is 8–12 times faster, and this difference tends to grow with the number of evaluated façades.Artículo Study of interior hygrometry profiles for the hygrothermal assessment of social housing envelopes in humid temperate climates(Elsevier, 2025-06-01) Arriagada Bustos, Roberto; Bobadilla Moreno, Ariel; Rubio Bellido, Carlos; Pérez Fargallo, Alexis; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas II (ETSIE); Ministerio de Ciencia e Innovación (MICIN). España; Universidad de Sevilla. RNM162: Composición, Arquitectura y Medio AmbienteThe building sector has focused on energy efficiency to promote sustainable development. However, incorporating energy efficiency measures in buildings usually affects their hygrothermal performance and can cause condensation and mold growth in their envelopes. These phenomena are related to the indoor climate, the enclosure setup, and the outdoor climate, so properly characterizing these parameters is fundamental for making hygrothermal assessments. From this perspective, the indoor climate is usually defined based on hygrometry classes or profiles, such as those in the ISO13788, EN15026, WTA, and DIN4108 standards. These standards have different limit values that seek to reflect the practices and cultures of use for buildings. The novelty of this research is to make new indoor hygrometry profiles based on post-occupational measurements. The indoor and outdoor humidity and temperature of 67 social housing units were monitored to build the new indoor hygrometry profiles, with 74,440 indoor and 4089 outdoor records. The excess indoor humidity was determined from these parameters, and the distribution of indoor variables using the outdoor temperature was analyzed. Subsequently, three types of new indoor hygrometry profiles were made that link outdoor temperature to excess indoor humidity, indoor relative humidity, and indoor air temperature. To test the new profiles, a comparative analysis of the hygrothermal performance of a built element was made using the WUFI Pro 6.4 software (168 simulations), considering the profiles of the ISO13788 standard and those developed in this study. The results show indoor environmental conditions are outside commonly accepted comfort ranges or more critical conditions from the hygrothermal point of view, with mean temperatures of 17 °C and relative humidities exceeding 80 % during 33.1 % of the monitored timespan. The results also show that the profiles developed in this study are more rigorous and properly reflect the indoor climate of the studied homes than the international standards commonly used. This research paves the way for new specific studies in similar climate conditions.Artículo Structural assessment of the medieval city wall of Seville (Spain) using low-cost accelerometers(Elsevier, 2025-06) Serrano Chacón, Álvaro Rubén; Mascort-Albea, Emilio J.; Romero Hernández, Rocío; Canivell, Jacinto; Muñoz Chavero, Fernando; Hidalgo Fort, Eduardo; Jaramillo Morilla, Antonio; Universidad de Sevilla.

TIC192: Ingeniería ElectrónicaThe remains of fortifications are commonly found embedded in the contemporary urban fabric of historic cities. Due to their typological nature, these heritage assets are usually elements of great size and impact on the urban landscape. Their location within cities exposes them to very specific risks, such as pollution, vibration, biodegradation, and anthropic factors, which must be taken into account for the proper conservation and maintenance of such remains. The case of the medieval wall of Seville (Spain), built on rammed earth, shows specific factors of vulnerability, degradation, and erosion which prompt the need for non-destructive techniques (NDT). In the present research, vibration-based inspection is used and, specifically, when subjected to ambient vibrations. The collection of accelerations, which covered a period of nine months, was conducted in different parts of the structure under study by using mainly high-resolution accelerographs. These data allowed to perform an exhaustive dynamic characterisation of this defensive structure. Among other findings, it was determined that the filling of cracks and voids in the walls increased the fundamental frequency by about 2 %. In addition, no serious damage to the structure was found. Knowledge of the historic buildings' condition is essential in order to determine the most appropriate intervention. To this end, a protocol for the global structural diagnosis of these buildings has been proposed. It is based on the recording of accelerations with low-cost accelerographs. Besides being an inexpensive protocol, it allows a quick decision making, since the dynamic characterization of the structure is performed by means of the fast Fourier transform. Basically, the designed protocol is based on the variation of the fundamental frequency of the structure between two time instants. These values are used for the calculation of a damage index. By means of an exhaustive review of conventional masonry buildings tested in the laboratory, the damage index has been correlated with the state of the structure prior to collapse. Specifically, this threshold, which ranges from DS4 to DS5 according to the criteria of the European Macroseismic Scale 1998 (EMS-98), provides a valuable reference point for the structural assessment of historical box-shaped constructions with conventional masonry load-bearing walls. This simplified procedure for structural diagnosis was applied in its initial phase at the White Tower. It was found that this protocol is able to identify the fundamental frequency of the structure with an error of <0.65 % in comparison to the results obtained through operational modal analysis methods.Artículo Investigación: Evaluación de la huella hídrica del uso y mantenimiento de los edificios. Aplicación a viviendas en Andalucía, España(Colegio Oficial de Aparejadores y Arquitectos Técnicos de Sevilla, 2025-01) Rivero Camacho, Cristina; Marrero Meléndez, Madelyn; Universidad de Sevilla. Departamento de Ingeniería del Diseño; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas II (ETSIE); Universidad de Sevilla. TEP172: Arquitectura: Diseño y TécnicaLas empresas de construcción pueden lograr el éxito financiero y reducir los impactos ambientales de los proyectos mediante la gestión cuidadosa de los presupuestos de los proyectos y la consideración simultánea de los costos económicos y los impactos ambientales. Sin embargo, durante su uso y mantenimiento, los edificios incurren en ramificaciones que van más allá de su construcción y que pueden ser igualmente significativas. En este trabajo se evalúa la huella hídrica (HH) de la etapa de mantenimiento y uso de los edificios a partir de la información de los presupuestos de los proyectos de construcción. Para ello, se emplea la herramienta computacional PREDICE. La herramienta pronostica los impactos ambientales indirectos, cuantificando los impactos incorporados en los materiales de construcción y la maquinaria a partir de su análisis de ciclo de vida. En este trabajo también se evalúan los impactos directos derivados del consumo de agua de los ocupantes a partir de los datos reportados. El capítulo explora la construcción de edificios residenciales en Andalucía, España, utilizando la base de datos de costos de construcción y el sistema de desglose de obras de la región. Se analiza el proyecto de construcción, concretamente su presupuesto (BoQ), para predecir las tareas de mantenimiento a lo largo de su ciclo de vida. Noventa y cinco unidades de trabajo de mantenimiento y su coste están definidos e integrados en la herramienta PREDICE. Se estudia un proyecto real: un edificio plurifamiliar de 4 plantas que proporciona vivienda social. Los resultados demuestran cómo el uso de la herramienta permite localizar las fuentes de mayor impacto a lo largo del ciclo de vida, facilitando así la toma de decisiones en cuanto a la reducción de costes económicos y ambientales. La huella hídrica de las viviendas consiste en torno al 80% de consumo directo por parte de los habitantes, mientras que un 20% se debe al agua incorporada en los materiales de construcción y la producción de energía. Además, el agua incorporada en la producción de energía es significativamente tan alta como la huella de materiales de construcción.Artículo Análisis territorial y caracterización tipológica-constructiva de la torre del Villar de Oria (Almería) mediante modelos digitales(Universitat Politècnica de València, 2025) Moya Muñoz, Jorge; Universidad de Sevilla. Departamento de Ingeniería del Diseño; Universidad de Sevilla. HUM799: Estrategias de Conocimiento PatrimonialDotted strategically around the entire province of Almería (Spain) are numerous defence elements belonging to the Kingdom of Granada. Recent investigations have produced new sets of plans using photogrammetry, the results of which have furnished information about the geometry and pathological status of the wall structures, as well as the factors that determined these elements. Other important studies have conducted spatial analyses of defence systems along the coast of Almería. However, only a few studies have approached these cultural assets from different scales, viewing them as a part of a general development. This article aims to provide new knowledge about these fortifications obtained through the use of digital models based on different software programs, and it therefore sheds light on their territorial scale, the scale of the architectural objects themselves and the scale of their materiality. Taking the Villar de Oria tower as a case study, the first step was to conduct a territorial study using geographical information systems in order to understand the reason behind the placement of the tower and its relationship with other nearby defence elements and the immediate vicinity. The next step was to examine geometric and architectural aspects of the tower, and the final stage of the study was a typologicalconstruction characterisation of the building systems and the materiality identified in the wall analysis. The results obtained contribute to existing knowledge about the cultural heritage associated with the old Kingdom of Granada in a general context. They also provide a baseline for conducting comparative and chrono-typological studies of other nearby defence infrastructures.Artículo Changing climate in Italian cities and Italian building regulations: Analysis focused on future climate change scenarios(Elsevier, 2025-06) Berti, Krizia; Bienvenido Huertas, José David; Rubio Bellido, Carlos; Romero Recuero, Irene; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas II (ETSIE); Universidad de Granada; Universidad de Sevilla. RNM162: Composición, Arquitectura y Medio AmbienteNowadays, the comfort conditions need to be assured throughout buildings lifetime. The building stock is not designed to cope with the climate variations expected in the coming decades. In this context, the climate classification used by countries to define the climate differences among the various areas of the country is of great relevance. This study analyses the climate classification of Italy under both current and future climate change scenarios. The aim is to show the obsolescence of the current climate classification regarding climate change by adapting the degree-day methodology to the climate data of the RCP 2.6, RCP 4.5, and RCP 8.5 scenarios in 2050 and 2100. The research shows that the degree-day variations predicted for the coming decades could totally change the configuration of the Italian climate zoning. By maintaining the current climate zoning in future scenarios, most municipalities would move at least one climate zone below, encouraging the thermal inefficiency of Italy's building stock in the coming decades and therefore, increasing the risk of energy poverty in the country.Artículo Evaluation of the physical and mechanical behaviour of rammed earth by incorporation of recycled glass(Elsevier, 2025) Canivell, Jacinto; Martín del Río, Juan Jesús; Solís Muñiz, Mario; Rodríguez Mariscal, José Daniel; Flores Alés, Vicente; Pontiga Romero, Francisco de Paula; Universidad de Sevilla.

FQM253: Electrohidrodinámica y Medios Granulares CohesivosCompacted soil walls provide environmental benefits due to their low impact and embodied energy. Although their mechanical strength is lower than other materials, they meet safety requirements. Current trends promote circular economy solutions, such as waste reuse. This study assesses recycled glass in lime- and cement-stabilized rammed earth as a replacement for natural sand to enhance waste management and soil properties. Ultrasonic inspection confirms increased compressive strength and density, especially in cement-stabilized mixtures. Statistical analysis reveals a direct correlation between crushed glass content and improved properties. The optimal replacement rate is 75% for lime and 100% for cement. The superior performance in cement-stabilized samples is due to a pozzolanic reaction absent in lime mixtures. Both binders show significant reductions in thermal conductivity, improving energy efficiency without compromising structural integrity. Ultrasound proves reliable for predicting compressive strength and stiffness, supporting the viability of this approach. The incorporation of recycled glass in compacted soil offers a sustainable construction alternative, balancing environmental benefits with enhanced mechanical and thermal performance.Artículo An indicator-based framework of circular cities focused on sustainability dimensions and sustainable development goal 11 obtained using machine learning and text analytics(Elsevier, 2025-03-01) Falah, Nadia; Falah, Navid; Solís-Guzmán, Jaime; Marrero Meléndez, Madelyn; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas II (ETSIE); Universidad de Sevilla. TEP172: Arquitectura: Diseño y TécnicaThe circular economy (CE) serves a practical pathway to facilitate sustainable development (SD) and achieve the Sustainable Development Goals (SDGs). Current frameworks for assessing city sustainability and circularity often lack comprehensibility and multi-dimensional indicator-based approaches, also fail to include city-level CE indicators. This study defines an innovative structure for defining the circular city indicators (CCIs) addressing critical gaps in existing methodologies and CCIs coverage of sustainability and SDGs, especially SDG11. The methodology encompasses an extensive literature review, integrating CE principles, macro level of CE parameters and current CCIs, resulting in a comprehensive list of 241 indicators. Using advanced machine-learning techniques—semi-supervised learning, text analysis, and clustering algorithms—enhances the accuracy, comprehensiveness of the indicator classification. The indicators are categorized into 3D space across environmental, economic, and social dimensions of sustainability. This multi-dimensional approach also reveals the relationships between CCIs and 16 SDG11 classes. The analysis shows 75% of CCIs are multi-dimensional, but, five SDG11 classes show the lowest coverage in the heatmap of CCIs probability distribution across SDG11 classes, indicating a need to revise SDG11 classes and the social indicators of CCIs. The findings offer urban planners and stakeholders a practical list of CCIs to evaluate sustainability and CE level in cities.Artículo Biocompuesto de fibra de bananeira, cáscara de amendoim de Manabí (Ecuador) y poliestireno expandido reciclado(Universidad del Bío-Bío, 2024) Echevarría Maggi, Eddie Efrén; Flores Alés, Vicente; Martín del Río, Juan Jesús; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas II (ETSIE)Esta investigación consiste en el desarrollo de un biocompuesto polimérico termoplástico en una matriz que se obtiene de la disolución del poliestireno expandido (EPS) reciclado, reforzado con fibra del pseudotallo de plátano y cáscara de cacahuete. Se elaboraron 6 modelos con los materiales, de los cuales el que obtuvo el mejor resultado fue la última dosificación, con un contenido del 63% de EPS diluido, 25% de fibra de plátano en tiras (40 mm) y 12% de cáscara de cacahuete triturado (1 a 3 mm). En la prueba de flexión alcanzó un MOR de 12 N/mm2 y un MOE de 55 N/mm2; la resistencia a la compresión fue de 8,60 N/mm2; 10% de absorción de humedad; y en el ensayo de conductividad térmica tuvo un valor de 0,095 W/m‧k que le otorga la propiedad de material aislante. Los valores alcanzados cumplen con las normas ecuatorianas INEN 3110 para tableros de partículas. Este trabajo evidencia la capacidad de los materiales utilizados para la manufactura de diversos componentes ligeros, resistentes y aislantes que se pueden emplear en las edificaciones.Artículo Datación radiocarbónica y constructiva del palacio civil del Pla de Nadal (Riba-roja de Túria, València)(Universitat de València, 2025-04-04) Macias Solé, Josep Maria; Alejandre Sánchez, Francisco Javier; Ribera Lacomba, Albert Vicent; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas II (ETSIE)El palacio del Pla de Nadal (Riba-roja de Túria, València) es uno de los edificios emblemáticos de la arquitectura civil de la Hispania tardoantigua. A pesar de la excepcionalidad de su decoración arquitectónica y de dos epígrafes, que hacen referencia a un tal Tebdemir/Teudinir, no existe unanimidad total en torno a la identidad del promotor y el contexto histórico de la obra, que oscilaba entre los siglos VII y IX. En este debate, presentamos una datación radiocarbónica de la fase constructiva inicial, elaborada a partir de cinco muestras de mortero constructivo. Ello permite establecer una cronología coincidente con la actividad del dux prouinciae Teodomiro, también conocido como Teodomiro de Orihuela. La sèrie de dataciones radiocarbónicas realizadas y su posterior modelado permiten indicar que la primera mitad del siglo VIII es el intervalo estadísticamente mas probable para la construcción del Pla de Nadal.Artículo A fuzzy logic approach to preventive conservation of cultural heritage churches in Popayan, Colombia(Taylor & Francis Inc, 2021) Chávez de Diego, María José; Prieto, Andrés J.; Turbay, Isabel; Ortiz, Rocío; Macías Bernal, Juan Manuel; Universidad de Sevilla. Departamento de Matemática Aplicada I (ETSII); Universidad de Sevilla. Departamento de Construcciones Arquitectónicas II (ETSIE)From a decision-maker’s perspective, the management of cultural heritage is a challenging task because of different objectives pursued, the public/private nature of heritage constructions studied, the wide variety of associated values (artistic, historical, cultural, economic) and diverse interests of different stakeholders. Careful consideration of environmental, social and economic factors is crucial in order to predict the functional service life of heritage constructions. This study outlines a new fuzzy system approach based on expert knowledge, which focuses on the serviceability of heritage buildings using a Mamdani fuzzy model. The method input considers 10 intrinsic variables directly related to the vulnerability of buildings and 9 external hazards, classified according to static-structural features and environmental hazards, which are considered useful for defining emergency programs in historical centres in South America (Colombia). The automation of inspection programs similar to the one described here may reduce the consumption of natural resources and benefit a more rational management of future maintenance actions. In general terms, this type of fuzzy logic model approach is designed to serve as an indicator for the future evolution of the functionality of buildings. This research contributes to the study of new service life models applied to heritage buildings in South America.Artículo Sistemas de certificación en clima templado(Universidad Nacional del Litoral, 2017-12) Mercader-Moyano, Pilar; Claro Ponce, José Carlos; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas I (ETSA); Universidad de Sevilla. Departamento de Construcciones Arquitectónicas II (ETSIE); Universidad de Sevilla. TEP172: Arquitectura: Diseño y TécnicaEl objetivo de este trabajo es dar a conocer el campo normativo y herramientas vigentes que permiten certificar la eficiencia energética de edificios en España, dentro de los países en Clima Templado, los documentos reconocidos para su realización; así como la vinculación de los mismos con Directivas europeas encaminadas a cumplir los compromisos fijados por la Convención Marco de las Naciones Unidas sobre el Cambio Climático. La comparativa entre las diferentes herramientas y con otros países de climas templados, permitirá identificar sus virtudes e inconvenientes, a fin de obtener conclusiones sobre las mejoras que podrían plantearse, desde el proceso de certificación y materia de eficiencia energética hasta las normativas que las regulan.Artículo The incorporation of recycled aggregate concrete as a strategy to enhance the circular performance of residential building structures in Spain(MDPI, 2025-03-17) Vásquez Cabrera, Alicia Isolina; Montes Delgado, María Victoria de; Llatas, Carmen; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas II (ETSIE); Universidad de Sevilla. Departamento de Construcciones Arquitectónicas I (ETSA); Agencia Estatal de Investigación. España; European UnionThe construction industry increasingly relies on concrete to meet growing urban population demands. However, concrete has a high carbon footprint, which contradicts the Sustainable Development Goals and the Circular Economy policies promoted by the European Commission. The use of Recycled Aggregate Concrete (RAC) is a cost-effective circularity strategy to mitigate environmental impacts. Several countries have integrated RAC into their standards and have achieved promising circularity results. Spain is committed to enhancing resource productivity and using circular materials through practices established during the design phase. Although the residential sector plays a significant role within the construction industry, the potential for circularity of RAC in such residential building structures remains unexplored. The present study aimed to fill this gap by assessing the circularity of four scenarios in a multi-family building using a circularity assessment method for residential building structures: the CARES Framework. The results revealed that RAC, following the Structural Code requirements, can enhance the circularity performance at the material level by up to 42.82%, at the element level by 21.68%, and at the system level by 10.81%. These results demonstrated that circularity declines as the assessment levels increase, which underscores the essential integration of circular materials with adaptability and disassembly criteria.Artículo Weather-driven cycling: developing a predictive model for urban bicycle usage based on five key weather factors(MDPI, 2025-02-11) Falah, Nahid; Falah, Nadia; Solís-Guzmán, Jaime; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas II (ETSIE); Universidad de Sevilla. TEP172: Arquitectura: Diseño y TécnicaWeather conditions significantly influence urban cycling, shaping both its frequency and intensity. This study develops a predictive model to evaluate the impact of five key meteorological factors, namely temperature, humidity, precipitation, wind speed, and daylight duration, on urban cycling trends. Using non-linear regression analysis, the research examines cycling data from 2017 to 2019 in Hamburg, Germany, comparing predicted values for 2019 with actual data to assess model accuracy. The statistical analyses reveal strong correlations between weather parameters and cycling activity, highlighting each factor’s unique influence. The model achieved high accuracy, with R2 values of 0.942 and 0.924 for 2017 and 2019, respectively. To further validate its robustness, the model is applied to data from 2021 and 2023—years not included in its initial development—yielding R2 values of 0.893 and 0.919. These results underscore the model’s reliability and adaptability across different timeframes. This study not only confirms the critical influence of weather on urban cycling patterns, but also provides a scalable framework for broader urban planning applications. Beyond the immediate findings, this research proposes expanding the model to incorporate urban factors, such as land use, population density, and socioeconomic conditions, offering a comprehensive tool for urban planners and policymakers to enhance sustainable transportation systems.Artículo Predictive stressors for the burnout syndrome in firefighters. A systematic review(Elsevier, 2025-06) García Iglesias, Juan Jesús; Bermejo Ramírez, Ana María; Goniewicz, Krzysztof; Fernández Carrasco, Francisco Javier; Gómez Salgado, Carlos; Camacho Vega, Juan Carlos; Gómez Salgado, Juan; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas II (ETSIE)Firefighters are exposed to situations where decision making is constant and affects not only the lives of those they serve, but also their own. The aim of this study was to identify stress-related factors that may predispose to the development of burnout in firefighters. A systematic review following the PRISMA 2020 statement was carried out in the Web of Science, Science Direct, Scopus, and Pubmed databases. The literature search was conducted in August 2024. The methodological quality was assessed using the critical appraisal tools for studies of the Joanna Briggs Institute. A total of 34 studies were included in this review. Among the risk factors identified as being associated with burnout were years of service, low levels of self-compassion, language barriers, alcohol consumption, age, proactive and negative coping styles, work stress, perceived stress, compassion fatigue, previous mental health history, performance in an external environment, family responsibilities, satisfaction with standard of living, feelings of loneliness, sleep disturbance, and work uniform. In this population, protective factors against the development of burnout included proactive coping, physical activity, perceived social support, self-concept clarity, and resilience. A number of risk and protective factors have been identified as predisposing the emergence of the burnout syndrome. These stressors have the potential to impact the worker, resulting in occupational illnesses and injuries, poor compliance with safety measures, and the onset of sleep disorders. Such consequences may have serious implications for the worker’s physical and mental health, as well as the health and integrity of third parties.Artículo ALHAMAT: analysing materiality of the Alhambra to elucidate the Nasrid dynasty's power in the Emirate of Granada(Cambridge University Press, 2025) Cardell Fernández, Carolina; García Contreras, Guillermo; Koffler Urbano, Teresa; Ríos Jiménez, Juan Manuel; García Porras, Alberto; Alejandre Sánchez, Francisco Javier; Sánchez Mesa, Domingo; Torre Espinosa, Mario de la; Mattei, Luca; Rodríguez Sánchez, David; Cano Padilla, Emilio; Losilla Martínez, Nicolás; Cardell Fernández, Esther; Nieto Liñán, José Miguel; Martínez Ávila, Fernando; Universidad de Sevilla.
