Estudio sobre los parámetros higrotermicos en la rehabilitación de casas cueva

Abstract

There are about 25.000 cave dwellings between the provinces of Almeria and Granada, lot of them to rehabilitate according to studies of local government, taking part in traditional architecture [1] in this area. Those constructions, some which are millenary, are being a guide for new projects and architectonic models as a consequence of climate change and energetic crisis of those years.

But, are they really bioclimatic buildings? Is it worthy to rehabilitate?. The excavated or troglodyted architecture is a kind of architecture which has passed to considerate cave-dwellings [2] from sub-standard housing to housing of the future (image nº1), as Mª Eugenia Urdinales Viedma of the University of Granada defines in her article. This type of buildings uses, partly, natural resources of surroundings of the chosen place to build as it is just consolidated ground. It takes advantage of its thermal inertia to obtain indoor thermal comfort. According to owners, they do not need fountains and energetic systems to maintain it. However, appropriated programmes of simulate do not exist to able to demonstrate its condition of bioclimatic dwellings, the use of equipment to monitor and the obtainment of suitable parameters, specially of moisture and temperature, are being necessary to demonstrate the thermal comfort as current housings. In this way, the rehabilitation of them is a starting point.
