- Evaluation of the energy consumption and overheating of homes in Miami, Guayaquil and Tenerife(2023) Avilés-Rodríguez, S. (Sebastián); Monge-Barrio, A. (Aurora)Year after year, global warming is elevating temperatures all over the world, causing indoor overheating environments that are inhabitable, and increasing energy demand in housing. Given this global concern, the aim of the study was to evaluate the thermal behavior of the house in the cities of Miami, Guayaquil and Tenerife, by a comparison assisted with a simulation for their indoor overheating hours and cooling demand, considering their climates, energy efficiency codes, and construction systems. These were: Miami, with two models (M1 with timber frame as the thermal envelope and M2 with a concrete block system), Guayaquil, with two models (G1 with the limitations for a dwelling with cooling system and G2 without it), and Tenerife with only one model. As a result, was found that Miami is the case with the higher consumption, which has a higher energy demand in a house of timber wall system than in a house of concrete block system, due to the thermal inertia. Despite that both models have the same usage time for the cooling system, meaning that more power was needed to reach the thermal comfort. Then, Guayaquil and Tenerife, are the cases that follows, with less consumption. While, according to the UNE EN 16798 methodology, in the indoor overheating hour evaluation in a year, Miami has the higher cases with a 31.43% of its hours in overheating for the timber frame system and a 22.88% for the concrete block system, followed by two cases in Guayaquil, with 4.2%, other with none, and also Tenerife with 2.43%. Nevertheless, the study showed that energy consumption is not necessarily related to the indoor overheating hours that a house could have. Given that, in the case of Guayaquil, where it doesn’t have any indoor overheating hour in all year, while Tenerife, with a similar energy consumption, has 2.43% of its hours in overheating. Due to the different parameters that the UNE follows in comparison with the cooling setpoints given by the CTE-DB-HE all over the year for the respective cases, because of their long warm seasons. Therefore, the study analyses the limits establish by the Spanish normative in relation to overheating, showing an overestimation assessment if the results with the UNE methodology are compared.
- Viabilidad de un cerramiento de madera contralaminada(2020-06) Rodríguez-González, J.R. (José Ramón); Cabrero-Ballarín, J.M. (José Manuel)La aparición de un nuevo sistema de construcción mediante paneles de madera contralaminada (CLT) ha supuesto un gran avance con respecto al resto de productos madereros, dotando al material de mayores prestaciones en relación con su estabilidad dimensional, resistencia, reacción al fuego y humedad. El desarrollo del CLT coincide con el auge de la construcción modular y la evolución del CNC, que permite una mayor exactitud y precisión de corte sobre el panel lo que supone la reducción de residuos y la optimización del material. Muchas son las ventajas que lo diferencian de otros materiales en ámbitos como la ecología, o la simplicidad y rapidez del proceso constructivo; aunque la actitud conservadora en la industria de la construcción y el desconocimiento técnico del material ralentiza y dificulta el desarrollo del sistema; haciéndole depender de otros materiales que requieren mayor tiempo de ejecución (como el hormigón o el acero) o son más contaminantes, impidiendo que puedan ser reciclados en su totalidad. Por este motivo, en el siguiente documento, se pretende destacar las novedades que el sistema aporta a la construcción analizando tanto su composición como su funcionamiento estructural, y planteando las distintas ventajas e inconvenientes que el material supone en relación con la ecología, metodología de construcción, planeamiento, etc. Dada su reciente incorporación en la arquitectura, el CLT compite con materiales mucho más consolidados como lo son el hormigón o el ladrillo, donde existe mayor dominio y con los que se es posible alcanzar mayores competencias constructivas y estructurales. Por tanto, se hace hincapié en conocer cuáles son las exigencias que pueden existir sobre un panel contralaminado colocado como cerramiento en un edificio, y las distintas soluciones utilizadas para resolverlas; estableciendo así una comparativa con el resto de materiales del mercado con el objetivo de comprobar la viabilidad real del sistema CLT a día de hoy.
- Reciprocal frame structure design with parametric tools(2020-06) Roig-Rendón, L. (Laura); Cabrero-Ballarín, J.M. (José Manuel); Hudert, M.M. (Markus Mathias)Nowadays, computational and digital design play an important role surrounding architecture practice, to the point its almost dependable on. Technological advancements have allowed computers to be an integral design tool for architects, as have parametric design tools which have allowed designers to quickly explore many ideas within a given set of parameters and quickly adjust them to visualise different results. These advances have allowed architects to push boundaries of geometrically more complex structures and, with the use of specialised programming softwares, any parametric model can be defined. The initial subject being studied for this research was structural design with parametric tools. After thorough research to give focus to this broad subject, and after various third-parties showed interest in contributing to the development of this project, we narrowed down the main focus: Develop, with a programming language, an optimised digital design-to-production tool for a timber reciprocal frame structure. We aimed the development of this project towards the its exhibition in the 2o Forum of Timber Constructions but, due to the unexpected Covid-19 pandemic, the congress got postponed, as did the proposal and construction for its final design. Due to this, this dissertation results in an extensive research and explanation for developing said tool and focuses mainly on explaining the development of the script and its possibilities to adapt to any surface geometry, which will further be the main tool used when proposing a final design for the next Forum.
