Ponencia Optimización energética: acercando la práctica profesional a distintos niveles educativos(Universitat Politècnica de Catalunya, 2023) López Lovillo, Remedios María; Aguilar Carrasco, María Teresa; Díaz-Borrego Algaba, Julia; Romero Gómez, María Isabel; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas I (ETSA)Este estudio aborda la preocupante desconexión entre la formación académica en arquitectura y la creciente necesidad de integrar la sostenibilidad y la eficiencia energética en la práctica profesional. Dada la importancia cada vez mayor de la eficiencia energética y la certificación en edificios, esta desconexión se ha convertido en un desafío significativo. El artículo propone una metodología educativa que simula la experiencia profesional, abordando la eficiencia energética, de forma interdisciplinar, desde el diseño inicial hasta la certificación. Esta metodología se aplicó en varios niveles educativos y demostró ser efectiva para capacitar a los estudiantes en la comprensión de conceptos de eficiencia energética y su aplicación práctica. Los resultados indican que esta innovadora metodología puede ayudar a cerrar la brecha entre la educación y la práctica profesional en arquitectura y preparar a los futuros arquitectos para abordar la sostenibilidad y la eficiencia energética de manera efectiva en sus proyectos y carreras.Ponencia Methodology for the characterization of building envelope: Virgen del Carmen Group at Valencia(Escuela Técnica Superior de Arquitectura de Valencia, 2023) Roa Fernández, Jorge; Galán-Marín, Carmen; Rivera-Gómez, Carlos; Palomares Figueres, María Teresa; Sola Caraballo, Javier de; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas I (ETSA)This communication is developed within the activities of the project funded by the Valencian Regional Government “The heritage consideration of the social Modern Movement’s public housing. The Virgen del Carmen group, revitalization, and energetic updating (MOMOvivso). In this project, a Modern Movement heritage social housing research is proposed to progress in the preservation of this architecture. Accordingly, a methodological model is made and applied to Valencia’s 614 housing estate, placed in the suburb zone named “El Cabañal”. This residential complex was designed by the architects Fernando M. García-Ordóñez and Juan M. Dexeus Beatty, and it was built between 1958 and 1962. It was developed under the new social housing regulatory framework, which considers different configurations, as well as new constructive techniques, aimed at standardizing the quality of their systems and components and improving the dwelling’s indoor comfort.The present communication is a summary of the analysis process leading to ideation of a comprehensive methodology for the buildings envelope characterization which has been performed under the referred regulatory framework and applied to different types of buildings. For this purpose, three action lines have been proposed: analysis of documentation and contemporary regulations, an inspection report with the visits carried out, and the envelope non-destructive testing.Ponencia Pedestrians’ urban thermal comfort: A machine learning assessment through transect walks(Cal-Tek srl, 2024) Rodríguez-Gallego, José Antonio; Diz Mellado, Eduardo María; Chacón Rebollo, Tomás; Galán-Marín, Carmen; Rivera-Gómez, Carlos; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas I (ETSA)As the effect of climate change increases, combined with the urban exodus, the relevance of thermal comfort becomes more and more evident, becoming an urgent need for all. This research presents a methodology for data collection of personal, microclimatic, and morphological variables relevant to the evaluation of thermal comfort in an urban environment. A dataset was collected and processed for a total of 200 surveys in 6 different transect walks in Seville, Spain, half of them in the historical city centre and the other half outside of it. Following the visualization of the data, a descriptive analysis of the main variables was carried out, showing the differences between the UTCI index and the real perceived thermal comfort, as well as the improvement associated to vegetation and spatiality. Additionally, the relevance of both air temperature and radiation on perceived thermal comfort was stated, showing how these two variables are intertwined regarding personal preferences. After this analysis, 3 reliable machine learning algorithms were used to predict the expected comfort: Random Forest, XGBoost and a Multilayer Perceptron. This was achieved with the R language, obtaining results of 0.6 accuracy for thermal comfort prediction in all cases, showing therefore the complexity of the problem.Ponencia Uso del BIM para el desarrollo de una infraestructura de datos para estimar la huella de carbono que generan los edificios a lo largo de su ciclo de vida en España(Universitat Politècnica de València, 2024) García Martínez, Antonio; Soust-Verdaguer, Bernardette; Rey Álvarez, Belén; Máximo Cubero, Germán Sicre; Alba Dorado, José Antonio; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas I (ETSA); Universidad de Sevilla. Departamento de Expresión Gráfica y ArquitectónicaPonencia La cobertura de yacimientos a ras de suelo, desde una visión sostenible(Universidade de Lisboa, 2024) Ordóñez Martín, Manuel Arturo; Gómez de Cózar, Juan Carlos; Benitez Bodes, Rosa María; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas I (ETSA)La disciplina de la conservación preventiva es clara en lo que respecta a las medidas de protección de yacimientos a ras de suelo (enterramientos, mosaicos, estructuras emergentes…) en lo relativo a las necesidades de conservación efectiva de las mismas. Dicha protección pasa en cualquier caso por la necesidad de cobertura de estas, con el fin de minimizar procesos de degradación debidos al ambiente al que quedan expuestos (desecación, radiación solar, heladicidad, condensación, cambios bruscos de variables higrométricas…), acercando al yacimiento in situ en lo posible, a las condiciones aportadas por una vitrina museológica. Encontramos en la bibliografía desde la década de los 80 del siglo XX, análisis tanto teóricos como relativos a experiencias de coberturas proyectadas o ejecutadas, que nos permiten reflexionar sobre la idoneidad y efectividad de la gran diversidad de sistemas abordados desde disciplinas diversas. Se reflexionará sobre parámetros como la necesidad de protección física ante agentes climáticos, la compatibilidad geométrica y material de la cobertura a la realidad del yacimiento, su protección térmica efectiva, e incluso sobre la necesidad de monitorizar las variables incidentes en los procesos de alteración. Pero será con el inicio del siglo XXI, cuando se aborde con mayor profundidad técnica y científica la idoneidad de los actuales sistemas de cobertura de excavaciones con una visión pluridisciplinar, gracias en gran parte al desarrollo de sistemas de monitorización, simulación y parametrización, tanto en actuaciones de cobertura permanente como temporal. El diseño de coberturas se entiende entonces desde el ámbito de la sostenibilidad, siendo necesario el diseño de coberturas de estructuras ligeras con escaso impacto físico y fácil mantenimiento con buen rendimiento en cuanto a control climático del espacio cubierto. Se detecta que, en muchos casos, las estrategias seguidas no han atenuado suficientemente, e incluso empeorado, los procesos físicos y químicos de alteración. Actualmente, el desarrollo de herramientas de parametrización a partir de algoritmos matemáticos permite el desarrollo de metodologías de diseño de coberturas capaces de optimizar las propiedades mecánicas de las estructuras, desde parámetros de flexibilidad y adaptabilidad al espacio objeto de protección, con un mínimo impacto físico en el mismo. Dentro de la línea de investigación desarrollada por el equipo autor del trabajo que aquí se expone, se está desarrollando una metodología global donde adicionalmente a la optimización estructural del modelo de cobertura, se prevé desarrollar sistemas de análisis del control de la totalidad de variables psicrométricas del espacio cubierto, empleando envolventes de doble capa y su simulación mediante herramientas de análisis de dinámica de fluidos, con el fin de aportar con el sistema desarrollado, un control efectivo de las variables de alteración. Presentamos en esta ponencia, los avances realizados en lo relativo a desarrollo y optimización de sistemas estructurales innovadores de materialidad diversa para coberturas ligeras de yacimientos a ras de suelo, abordándolos desde visiones como optimización material, adaptabilidad física y arquitectónica e incluso sostenibilidad mediante análisis de ciclo de vida de los mismos.Ponencia La cooperación internacional de la Junta de Andalucía: una revisión sistemática y puesta en valor desde el prisma iberoamericano(Universitat Politècnica de Catalunya, 2025) López de Asiain Alberich, María; Rey Pérez, Julia; Oliveira, Silvana Rodrigues de; Herrera-Limones, Rafael; Universidad de Sevilla.

Departamento de Construcciones Arquitectónicas I (ETSA)Ponencia Mapping the acoustics of Ripon cathedral(RWTH Aachen University, 2019) Alvarez Morales, Lidia; López, Mariana; Alvarez-Corbacho, Ángel; Bustamante, Pedro; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas I (ETSA); Ochmann, Martin; Vorländer, Michael; Fels, JaninaCathedrals are amongst the most significant buildings of European cultural heritage and are of great significance for the study of intangible heritage. This paper presents a detailed acoustic study of Ripon Cathedral, an English medieval cathedral whose history goes back to the 7th Century. Experimental and simulation techniques have been applied in order to develop a better understanding and preservation of the acoustic environment of Ripon cathedral. This research addresses the acoustical conflict inherent to this kind of spaces: its extreme reverberation builds a unique environment for vocal and instrumental music, specially organ music, but at the same time those same characteristics are a challenge for the intelligibility of the spoken word, which is crucial to the delivery of sermons. Acoustic maps have been created based on the diverse uses of the space, the history of the building, and its architectural features. Such maps have been used to analyse the acoustic characteristics throughout the cathedral’s interior space. This work is part of the ECfunded Marie-Sklodowska- Curie Fellowship ‘Cathedral AcousticsOtro Herramientas de ayuda al diseño inteligente de edificios de bajo impacto ambiental en España(2024-10-29) Llatas, Carmen; Soust-Verdaguer, Bernardette; Gutiérrez Moreno, José Antonio; Fernández Gálvez, María Dolores; Castro, Luis; Cagigas Muñiz, Daniel; Universidad de Sevilla.

TEP986: Digital Architecture for Sustainability Lab (DatUS-Lab)La Comunidad Científica proporciona evidencias del relevante papel que juega el sector de la construcción en el cambio climático, generando cerca del 40% de las emisiones de gases de efecto invernadero. Ante esta situación, la sociedad demanda edificios de menor impacto. Por ello, en España la descarbonización del sector de la edificación es un objetivo prioritario para mitigar los efectos adversos del cambio climático y lograr la transición ecológica. Para 2030, los edificios deberían reducir drásticamente su carbono embebido en un 40%. El papel del diseñador es clave. Sin embargo, una principal limitación para lograr este objetivo es la falta de herramientas automatizadas e integradas en la fase de diseño que permitan informar de cuáles son los elementos constructivos de bajo impacto. Este estudio presenta dos herramientas llevadas a cabo en la Universidad de Sevilla por el equipo de investigación TEP-986 datUS-Lab (Digital Architecture for Sustainability), en el marco de dos proyectos de investigación estatales: un catálogo de elementos constructivos de baja huella de carbono implementado en la metodología BIM (BIM-ZEN), y una herramienta de simulación del impacto de elementos constructivos en modelos de edificios (DECIDE). Ambas están basadas en la metodología de Análisis de la Sostenibilidad del Ciclo de Vida y emplean técnicas de Machine Learning para la identificación y selección de procesos optimizados. Se presentan sus bases y fundamentos. Con todo ello, se pretende contribuir a la transición ecológica y digital.Ponencia Unlocking the potential of material and building passports in the transition to a circular economy in buildings: a critical review(Springer, 2024) Gómez Gil, Marta; Askar, Rand; Karanafti, Aikaterina; Trubina, Nika; Blázquez de Pineda, María Teresa; Güngör, Bengü; Bragança, Luís; Leindecker, Gerald; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas I (ETSA); Universidad de Sevilla. TEP999: Habitae Habitabilidad, Acondicionamiento y Energía en ArquitecturaThe transition towards a Circular Economy (CE) stands as a pivotal strategy in reshaping our prevailing consumption patterns towards more sustainable resource management. Within this context, the European Union places a strong emphasis on elevating recycling and renovation rates while reducing dependence on primary resources, with a particular focus on the construction industry. Material and Building Passports have emerged as potential tools to facilitate this transition. They play a multifaceted role in CE, serving to raise awareness of the building’s performance, functioning as digital repositories of extensive data, and acting as consulting instruments for stakeholders involved in renovation actions, energy management, and building operation. However, a universally accepted definition of these tools remains elusive, and diverse interpretations persist. To contribute to a deeper understanding of these tools, this study embarks on a comprehensive review, tracing their evolutionary journey and delving into the potentialities and synergies they offer in fostering circularity throughout the life cycle of buildings. It also examines the barriers hindering their full-scale development and adoption, including the lack of standardization and legislative measures, financial constraints, issues of stakeholder involvement and responsibility, as well as challenges associated with data accessibility.Ponencia Material and building passports as supportive tools for enhancing circularity in buildings(Springer, 2025) Leindecker, Gerald; Askar, Rand; Güngör, Bengü; Blázquez de Pineda, María Teresa; Turbina, Nika; Gómez Gil, Marta; Karanafti, Aikaterina; Bragança, Luís; De Wolf, Catherine; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas I (ETSA); Universidad de Sevilla. TEP999: Habitae Habitabilidad, Acondicionamiento y Energía en ArquitecturaThe twin transition driven by European agendas emphasises the dual benefits of integrating digital technologies with green sustainability concepts. In the built environment and construction sector, this integration is exemplified by leveraging digitalisation to enhance circularity in construction processes. This chapter explores this synergy by focusing on the development and application of Material and Building Passports (MPs and BPs). It discusses how these passports are digitally utilised to optimise circularity aspects of buildings and construction materials. The chapter delineates the evolution of MPs and BPs, clarifying their various definitions, variants, and potential applications to support the sector's twin transition. Additionally, it examines numerous initiatives and pilot projects aimed at defining the passports, including their requirements and conditions, and the standardisation efforts to ensure their widespread adoption through a unified content structure. The roles of MPs and BPs across different lifecycle stages are elaborated, with a particular emphasis on the enhanced functionalities enabled by Building Information Modelling (BIM). Moreover, the chapter identifies several barriers impeding the full adoption of these passports, such as legislative and standardisation challenges, information security concerns, lack of collaboration, and issues with information accessibility and sharing. It concludes by suggesting future research directions to further refine the passports for optimised use by construction industry stakeholders.Ponencia Propuesta metodológica simplificada para la aplicación del Análisis de Ciclo de Vida (ACV) en tipologías de viviendas unifamiliares(Ayuntamiento de Málaga, 2016-10-05) Soust-Verdaguer, Bernardette; Llatas, Carmen; García Martínez, Antonio; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas I (ETSA); Consejería de Fomento, Articulación del Territorio y Vivienda; Universidad de Sevilla. TEP986: Digital Architecture for Sustainability Lab (Datus-Lab)El sector de la edificación constituye uno de los que mayores impactos generan en relación a las emisiones de CO2 y el consumo de recursos. Al tiempo que el sector residencial y en particular, la tipología de vivienda unifamiliar supone en su conjunto la que más más emisiones de CO2 genera. En ese sentido se hace necesaria cada vez más la utilización de nuevas herramientas que contribuyan al desarrollo de edificios que generen menos impacto en el medioambiente, desde fases iniciales del diseño. Por otra parte, la metodología de Análisis de Ciclo de Vida, es reconocida como la más completa, al tiempo que aún encierra prejuicios sobre su complejidad y esfuerzo en la recolección de datos. La literatura de referencia reconoce caminos hacia su simplificación, mediante entre otros la integración del BIM como formato de entrada de información para la aplicación de la metodología. El objetivo de esta comunicación es el desarrollo de una propuesta metodológica para llevar adelante la evaluación ambiental de viviendas unifamiliares basada en el Análisis de Ciclo de Vida (ACV), incorporando simplificaciones al procedimiento. Los resultados confirman la viabilidad del desarrollo de la metodología que pueda ser aplicada por técnicos de la edificación, durante las fases de diseño y proyecto. Se finaliza con un conjunto de conclusiones y recomendaciones sobre la metodología desarrollada.Ponencia Simplificaciones aplicadas al análisis del ciclo de vida de viviendas(Ayuntamiento de Málaga, 2015-10-07) Soust-Verdaguer, Bernardette; Llatas, Carmen; García Martínez, Antonio; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas I (ETSA); Consejería de Fomento, Infraestructuras y Ordenación del Territorio de la Junta de Andalucía; Universidad de Sevilla. TEP986. Digital Architecture for Sustainability Lab (Datus-Lab)A nivel mundial se reconoce la existencia de más de 600 métodos y herramientas para la evaluación ambiental de los edificios. La aplicación del Análisis del Ciclo de Vida como (ACV) herramienta de evaluación constituye una las más completas. De acuerdo a lo definido por el marco normativo ISO 14040 su aplicación se basa en 4 etapas, la definición de los alcances y objetivos del sistema, la elaboración del inventario del ciclo de vida, la elaboración de impactos del ciclo de vida y finalmente la interpretación de los datos obtenidos. Su aplicación en el sector de la edificación encierra prejuicios sobre su complejidad y dificultad, esto hace que se haga necesaria la incorporación de simplificaciones al procedimiento atendiendo a sus impactos y repercusiones en la representatividad de los resultados obtenidos. Este trabajo persigue a través de una revisión bibliográfica de trabajos desarrollados en los estos últimos años, identificar y analizar simplificaciones posibles. Se identifican las etapas en cuales han sido desarrolladas, se definen sus propósitos y consecuencias en los resultados obtenidos. Los resultados obtenidos muestran la disparidad de criterios y herramientas utilizadas durante la incorporación de simplificaciones aplicación de la metodología. Las mayores simplificaciones limitan la aplicación del análisis a las fases de producción de materiales y consumo energético en fase de uso.Ponencia Digital technologies and material passports for circularity in buildings: an in-depth analysis of current practices and emerging trends(Springer, 2024) Trubina, Nika; Leindecker, Gerald; Askar, Rand; Karanafti, Aikaterina; Gómez Gil, Marta; Blázquez de Pineda, María Teresa; Güngör, Bengü; Bragança, Luís; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas I (ETSA); European UnionThe construction industry is undergoing a significant transformation driven by digitalization and an unwavering commitment to implementing circular economy (CE) principles and sustainability into its core practices. Emerging digital technologies (DTs), such as Material Passports (MPs), Building Information Modelling (BIM) Artificial Intelligence (AI) and Scanning technologies, Blockchain technology (BCT), the Internet of Things (IoT) stand out as pivotal tools capable of expediting the transition towards CE implementation in buildings. This study highlights the significant potential of six DTs to support CE application throughout the building lifecycle. Furthermore, it delves into the potential synergies among these diverse DTs, highlighting the additional benefits that collaboration can bring across different lifecycle stages of a building project. Particular emphasis is placed on the integration of MPs with other DTs, showing promise in assessing resource availability, volumes, and flows. This integration optimizes waste reduction and recycling plans, contributing to more precise selective and smart deconstruction planning. The combined use of DTs offers substantial benefits to stakeholders, enabling them to make informed decisions regarding maintenance and understand the current quality of specific materials. Through these means, the study aims to provide a comprehensive overview of the array of DTs propelling circular building practices. It also explores emerging trends in this dynamic field, scrutinizing the effectiveness of adopting these technologies throughout the building life cycle stages, and anticipating potential challenges these technologies may face.Ponencia An overview of CFD simulation plug-ins within the BIM environment for urban microclimate analysis(CAL-TEK, 2024) Campos Rosa, Lucía; Rivera-Gómez, Carlos; Galán-Marín, Carmen; Lizana Moral, Francisco Jesús; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas I (ETSA); Bruzzone, Agostino G.; Zacharewicz, Gregory; Cimino, Antonio; Universidad de Sevilla. TEP206: Sath Sostenibilidad en Arquitectura, Tecnología y Patrimonio: Materialidad y Sistemas ConstructivosDespite the vast array of building simulation tools available, there is a scarcity of microclimate-sensitive decision-support tools for urban planning early-stage design, where crucial decisions shaping microclimate and comfort conditions are made. Within the collaborative work environment of Building Information Modelling (BIM), researchers are innovating methods and software like Computational Fluid Dynamics (CFD) simulation tools to enhance and integrate outdoor environmental research in the design process. Incorporating CFD methods via plug-ins into architectural design software may represent a significant advancement in interoperability. However, the reliability, computational complexity, and accuracy of BIM-CFD integration remain unclear. To address the knowledge gap, this paper aims to conduct an in-depth study and comparison of the applicability of some CFD plug-ins for urban microclimate analysis in BIM projects. This systematic approach aims to build a comprehensive framework of BIM-CFD interoperability via plug-ins, identifying limitations and opportunities for integrating microclimate analysis into BIM design. Significant challenges are detected, particularly in data loss during model transfers and the limited scope of current CFD application methods. This review identifies the need for future research to explore multiobjective simulations and the integration of CFD feedback to optimise design, inform decision-making and optimise resources from the early design stages.Ponencia Building parameter influence on overheating and undercooling risks in the Mediterranean social housing stock of southern Spain(EDP Sciences, 2024) Calama-González, Carmen María; Suárez, Rafael; Escandón Ramírez, Rocío; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas I (ETSA); Universidad de Sevilla. Departamento de Estructuras de Edificación e Ingeniería del Terreno; Junta de Andalucía; European Commission. Fondo Social Europeo (FSO); Universidad de Sevilla. TEP130: Arquitectura, Patrimonio y Sostenibilidad: Acústica, Iluminación, Óptica y EnergíaIn recent years, there has been a notable rise in temperatures, along with an escalation of heatwaves as a consequence of global warming. This phenomenon conspicuously impacts summer and winter, leading to modifications in the building energy balance, such as higher overheating risks, increased cooling energy consumption or decreased heating demand. Consequently, evaluating the risks associated with overheating and undercooling discomfort in the existing stock becomes of great significance, prior to the implementation of retrofit strategies. In this line, a parameterized and validated building stock simulation model has been constructed, defined from the most representative building archetype, allowing the evaluation of overheating and undercooling risks in the existing social housing stock in southern Spain. To do so, monitored data from a case study and extensive information of a public building database have been considered. The most influential parameters on adaptive overheating and undercooling discomfort have been defined through sensitivity analysis. The study highlights the importance of window configuration and air-related parameters on overheating and undercooling, being also worth noting the relevance of ventilation schedules, even more than ventilation rates. These findings are crucial for defining energy retrofit solutions aimed at minimizing the effects of global warming, while taking into consideration undercooling conditions.Ponencia Developing a data infrastructure to obtain reference values, baselines, and benchmarks for the Whole Life Carbon implementation in buildings in Spain: INDICATE project(IOP Publishing, 2024) Soust-Verdaguer, Bernardette; García Martínez, Antonio; Rey Álvarez, Belén; De Diego, B.; De la Fuente, A.; Fernández Gálvez, María Dolores; Castro Torres, Luis ; Röck, Martin; García González, L.; Julián García, M.; Fernández, P.; Sicre Álvarez, Germán; Cubero Cruz, M.; Alba Dorado, José Antonio; Universidad de Sevilla.

HUM799: Estrategias de Conocimiento PatrimonialCurrently, there is an urgent need to implement whole life carbon emissions reduction measures in Mediterranean regions. In the Spanish context, although there are several initiatives there is no national harmonised LCA method or national database of construction products with associated environmental data. This paper presents a summary of the methodology, preliminary results and lessons learnt from the INDICATE project Spain, whose focus on accelerating the data infrastructure for implementing WLC metrics in the building sector in Spain. It aims to provide a scientific-technical support to develop data of the national building stock harmonised with Level(s) framework and develop a robust national data infrastructure to conduct the WLC assessment, as well as providing agreed outcomes including reference values, baselines and benchmarks, contributing to the integration of the WLC in policy makers' decisions, existing regulations, and market innovation, involving key actors from representative regions in Spain and creating a multi-stakeholder network. The method is based on three main pillars: co-creation, development of new data, and collection of real LCA data. Several areas for future action have been identified, including the application of data science and technologies such as AI for the analysis of synthetic and real cases and the address of specific data gaps.Ponencia Assessing overheating and undercooling risks in existing public secondary schools in Mediterranean climate(IOP Publishing, 2024) Calama-González, Carmen María; Escandón Ramírez, Rocío; Llanos-Jiménez, Jesús; Suárez, Rafael; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas I (ETSA); Universidad de Sevilla. Departamento de Estructuras de Edificación e Ingeniería del Terreno; Junta de Andalucía; Ministerio de Ciencia, Innovación y Universidades (MICINN). España; Universidad de Sevilla. TEP130: Arquitectura, Patrimonio y Sostenibilidad: Acústica, Iluminación, Óptica y EnergíaDuring the last years, there has been a significant increase in temperatures, as well as in the intensity and duration of heatwaves due to climate change, which noticeably affects summer, but also winter conditions. Thus, assessing overheating and undercooling risks in the existing stock is of the utmost importance, especially in highly occupied educational buildings with natural ventilation systems. These risks do not only affect students' thermal comfort but their health and academic performance. Besides, COVID-19 has highlighted the energy vulnerability of schools and the complexity to adopt adequate strategies to enhance indoor environmental quality. To assess overheating and undercooling risks in educational buildings in southern Spain, a parameterized and validated building simulation model has been constructed from a representative school using monitored data. Through sensitivity analysis techniques, the most critical variables on adaptive thermal comfort in summer and winter have been determined. The study highlights the difficulty of guaranteeing a balance between indoor air quality and thermal comfort, since not only infiltration and ventilation rate have a key impact on thermal comfort, but also and more importantly ventilation schedules. These conclusions are vital to propose retrofit strategies to mitigate climate change while tackling undercooling, using parameterized building-archetype models, which allow to simulate other representative case studies in the area.Ponencia Architecture in Conservation Areas: Humboldt Hotel, Caracas, Venezuela(Universidad Politécnica de Valencia, 2024) Suzzarini-Flores, Andrés-Alejandro; Ponce Ortiz de Insagurbe, María Mercedes; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas I (ETSA); Viñals, María José; López González, ConcepciónThe following study provides the latest environmental strategies to reduce the building’s energy consumption and mitigate the environmental impact that the Humboldt Hotel will have during the life cycle of the building. As a result, a compilation of historical data from official sources is provided, as well as a technical investigation through Revit Insight and Designbuilder programs to evaluate the energy performance of the building and provide a timely and assertive action plan.Ponencia Measuring the correlation between carbon embodied emissions, economic and social impacts of building elements in Spain(IOP Publishing, 2024) Soust-Verdaguer, Bernardette; Castro. L.; Fernández Gálvez, María Dolores; Gutiérrez Moreno, José Antonio; Cagigas Muñiz, Daniel ; Palumbo, Elisabetta; Llatas, Carmen; Universidad de Sevilla. Departamento de Construcciones Arquitectónicas I (ETSA); Universidad de Sevilla. TEP986: Arquitectura y SostenibilidadBuildings produce significant environmental impacts, as well as economic and social impacts in society. The Life Cycle Sustainability Assessment (LCSA) is recognised as an appropriate method to assess their impact following a Triple Bottom Line (TBL) approach. In the European context, incoming regulations for building are beginning to consider the embodied environmental impact of new construction. However, the economic and social implications of those concerns have been scarcely explored. Implementing the LCSA on different building elements involves a great amount of data. Difficulties in data management and the weighting of different dimensions are also detected as methodological challenges. To reduce the effort in the LCSA implementation in the building design process the Building Information Modelling TBL (BIM_TBL) database includes a collection of the most frequently used building elements in Spain, which is integrated in BIM. This study presents the main results of data analysis of the BIM_TBL database to determine the correlation between the environmental, economic, and social impacts generated by different constructive solutions. To that end, a Knowledge Discovery Database (KDD) analysis was performed to support the multi-dimension integration in the design process. This study provides recommendations to integrate a multi-dimension approach in the building design process.Ponencia Comparison of 16 national methods in the life cycle assessment of carbon storage in wood products in a reference building(IOP Publishing, 2024) Ouellet-Plamondon, Claudiane M.; Balouktsi, Maria; Delem, Laetitia; Foliente, Greg; Francart, Nicolas; García Martínez, Antonio; Hoxha, Endrit; Lützkendorf, Thomas; Nygaard Rasmussen, Freja; Peuportier, Bruno; Butler, Jarred; Birgisdóttir, Harpa; Bragança, Luís; Dowdell, David; Dixit, Manish; Gomes, Vanessa; Gomes da Silva, Maristela; Gómez de Cózar, Juan Carlos; Kjendseth Wiik, Marianne; Llatas, Carmen; Mateus, Ricardo; Pulgrossi, Lizzie Monique; Röck, Martin; Saade, Marcella Ruschi Mendes; Passer, Alexander; Satola, Daniel; Seo, Seongwon; Soust-Verdaguer, Bernardette; Veselka, Josef; Volf, Martin; Zhang, Xiaojin; Frischknecht, Rolf; Universidad de Sevilla.

TEP986: Arquitectura y SostenibilidadWood and bio-based construction products are perceived as a way to use renewable resources, to save energy and to mitigate greenhouse gas (GHG)-emissions during production and to store carbon during the entire service life of the building. This article compares the carbon footprint per kilogram of wood products (softwood beams, plywood, oriented strand board panel, and fibre board) from the perspective of the life cycle assessment methodology for greenhouse gas (GHG) emissions of practitioners from 16 countries participating in the IEA Annex 72. These materials are used in PAL6 softwood structure multi-residential building. This article aims at comparing the carbon footprint accounting methods from 16 countries for PAL6 multi-residential building. Each national team applied the reference study period (RSP), life cycle modules covered, modelling rules, the geographical scope of inventory data as well as the LCA database according to its specific national method. The results show that there are three types of methodology to assess a building with biogenic content (0/0, -1/+1, -1/+1*). The results were more variable plywood, oriented strand board, and fibreboard than the softwood beams due to the variability in the wood transformation processes among the countries. A net negative carbon balance was obtained for the softwood beam for the countries using -1/+1* with a clear assumption of the fraction of the carbon permanently stored at the end-of-life (EoL). The carbon storage is only possible if it is secured at the EoL. Participating countries apply different definitions of permanence and EoL scenarios. Guideline on assessing, monitoring, and legally reporting carbon storage at the EoL are needed, based on concertation between standard, life cycle assessment, wood industry, and climate experts.
