| description |
The large amount of Spanish earth built heritage that already requires urgent rehabilitation, the emergence of new sustainability criteria that pushes up contemporary earth architecture and the need of compliance with the standard for the reintroduction in the Spanish construction system of the earth building techniques, oblies to review the data and the methodology for the parameterization of the earth wall’s thermal behaviour. It’s necessary the homologation of the earthen buildings to the current building regulations and the formulation of new protocols adapted to the peculiarity of their dynamic behaviour. The lack of research related to quantification of the thermal behaviour of this type of building solutions casts doubts about their conformability. The objective of the present research is to characterize the thermal behaviour of a north rammed earth façade of a contemporary building taking into account both the heat flow from the inside ambient towards the inside of the wall and the heat flow from the wall towards the outside ambient. Methodology is based on monitoring the ambient surface temperatures and the heat flow under certain conditions (in compliance with the standardized in situ monitoring tests of the thermal behaviour of building envelopes) to obtain the U values. It is characterized the dynamic behaviour of the wall. The results characterize the dynamic behaviour of the wall, reveal its positive vulnerability to the outside temperature and determine the inefficiency of the regulation’s methodology in case of walls with thermal inertia. Despite this, the data obtained improves significantly the values that are reflected in the current Spanish building regulations and those that appear in reference bibliographies. |

La gran cantidad de patrimonio construido en tierra en España, que precisa de una rehabilitación urgente, la aparición de nuevos criterios de sostenibilidad que empujan la construcción contemporánea en tierra, y la necesidad del cumplimiento de la norma para la reintroducción de las técnicas de construcción en tierra en el escenario de la construcción española, obligan a revisar los datos y la metodología para la parametrización del comportamiento térmico de los muros de tierra. Es precisa la homologación de los sistemas en la normativa vigente, y la formulación de nuevos protocolos de cuantificación adaptados a la peculiaridad del comportamiento dinámico de este tipo de construcciones. La falta de estudios relativos a la cuantificación efectiva del comportamiento térmico de estos sistemas constructivos, alimenta las dudas sobre su confortabilidad. El objetivo de esta investigación es caracterizar el comportamiento térmico de un muro de tapia calicostrada (un sistema tradicional en la zona de estudio) de la fachada norte de un edificio de vivienda de reciente construcción, teniendo en cuenta tanto los valores de flujo desde el interior de la vivienda hacia el interior del muro, como los de flujo desde el muro hacia el exterior. La metodología se basa en la monitorización de la temperatura ambiente y superficial, y en el flujo de calor en unas condiciones determinadas, en cumplimiento de los ensayos estandarizados de monitorización in situ del comportamiento térmico de los cerramientos, para la obtención de los valores U del cerramiento. Se caracteriza el comportamiento dinámico del muro. Los resultados revelan la vulnerabilidad de la transmitancia respecto a la temperatura exterior, y la ineficacia de la metodología para muros de gran inercia térmica. A pesar de ello, los datos obtenidos mejoran significativamente los valores que se reflejan en la normativa vigente de edificación española, y los aparecidos en bibliografías de referencia.
