El proyecto de innovación docente Crossworks se entiende como un crisol de trabajo donde se reunen todas las asignaturas del primer curso de Grado en Architecture, en un intento de provocar relaciones transversales entre ellas que mejore el rendimiento del alumno en las ciencias básicas y le otorgue una visión integradora y global de la arquitectura. El proyecto se ha estructurado en varias fases, una en aula, después la visita “in situ” al edificio objeto de análisis, y posteriormente la realización de talleres con una temática común pero trabajados desde asignaturas aparentemente distantes como Matemáticas e Historia del Arte, o Física y Dibujo Arquitectónico. Los resultados han sido altamente esperanzadores, no solo en el rendimiento académico de los alumnos, sino en la cohesión del grupo y la integración de las distintas culturas participantes.

Achieving European climate neutrality by 2050 requires further efforts not only from the industry and society, but also from policymakers. The use of high-efficiency cogeneration facilities will help to reduce both primary energy consumption and CO2 emissions because of the increase in overall efficiency. Fuel cell-based cogeneration technologies are relevant solutions to these points for small- and microscale units. In this research, an innovative and new fuel cell-based cogeneration plant is studied, and its performance is compared with other cogeneration technologies to evaluate the potential reduction degree in energy consumption and CO2 emissions. Four energy consumption profile datasets have been generated from real consumption data of different dwellings located in the Mediterranean coast of Spain to perform numerical simulations in different energy scenarios according to the fuel used in the cogeneration. Results show that the fuel cell-based cogeneration systems reduce primary energy consumption and CO2 emissions in buildings, to a degree that depends on the heat-to-power ratio of the consumer. Primary energy consumption varies from 40% to 90% of the original primary energy consumption, when hydrogen is produced from natural gas reforming process, and from 5% to 40% of the original primary energy consumption if the cogeneration is fueled with hydrogen obtained from renewable energy sources. Similar reduction degrees are achieved in CO2 emissions.
