. From the experimental characterization of the hygrothermal properties of straw-clay mixtures to the numerical assessment of their buffering potential. Building and Environment, Elsevier, 2016, 97, pp.69 -81. 10.1016/j.buildenv.2015 1 From the experimental characterization of the hygrothermal properties of straw-clay mixtures to the numerical assessment of their buffering potential ABSTRACTThe development of innovative materials has to respond to both environmental and energy concerns. Bio-based materials are relevant because they are made from renewable raw materials and are carbon neutral. Similarly, unprocessed earth has a very low embodied energy. In this paper, the basic hygrothermal properties of straw-clay samples provided by two French companies were determined. Mixes with densities lower than 450 kg.m -3 would be suitable for use as self-insulating material in current construction. In addition, the material showed a high sorption capacity and very high water vapour permeability. The measurements were then implemented in a numerical model in order to simulate the hygric response of a small room. The straw-clay mixture was found to have a moisture buffering effect of the same magnitude as walls made of hemp concrete and largely higher than conventional walls. The influence of various indoor finishing materials was investigated through additional simulations.

“…Granüllü malzeme serbest veya sıva ile karıştırılarak kullanılabilir. Ayrıca hafif beton üretimi için de kullanılır [82]. Bu malzemelerin ısı iletim katsayısı oldukça yüksektir (0,08-0,20 W/m.K), ancak yüksek yoğunlukta (290-750 kg/m 3 ) düşük ısıl yayınım katsayısı seviyelerinin elde edilebilir.…”

“…La máxima lluvia batiente I' SΘ (l/m 2 año) que se recibe sobre la fachada antes de que la misma comience a secarse, se determina mediante la relación [4], considerando en el sumatorio, únicamente los m registros horarios contenidos dentro de cada uno de estos periodos de humedecimiento, en los que la dirección D del viento impulsa una cantidad de agua no nula sobre la fachada de orientación Θ. De nuevo, como coeficiente de ajuste k, se emplea un valor igual a 2/9 (s/m).…”

Revisión y mejora de la caracterización del grado de impermeabilidad requerido por el CTE DB-HS1 para fachadas de edificación. Informes de la Construcción, 67(537) RESUMENEl Código Técnico de la Edificación aprobado en 2006, asigna por primera vez en España diferentes requisitos básicos para los cerramientos verticales de edificación, destinados a limitar el riesgo de presencia inadecuada de humedad en el interior de los edificios. La solicitación por humedad, estimada mediante diversos parámetros climáticos, permite ajustar la exigencia de estos requisitos para cada emplazamiento y fachada. Sin embargo, estos parámetros presentan actualmente posibilidades de mejora que pueden dar lugar a una asignación más adecuada del grado de impermeabilidad y con ello, de los requisitos de diseño necesarios. Este artículo revisa estos parámetros climáticos, presenta otros utilizados internacionalmente para el mismo propósito y caracteriza en el territorio español los factores que determinan la solicitación por humedad, haciendo posible mejorar la prestacionalidad de los requisitos básicos impuestos para las fachadas de los edificios.Palabras clave: Lluvia batiente; presión eólica; estanqueidad; Código Técnico de la Edificación; diseño de fachadas.
