Performance assessment of thermal bridge elements into a full scale experimental study of a building façade

In this paper, an experimental and numerical approach to the characterization of thermal bridges is presented. The need for this characterization was found within an experimental study in a 2 floor high facade. This facade was constructed with 3 concrete elements which were placed in it to produce a similar thermal bridge effect to the one created by floor slabs traditional building construction in Spain. Commonly applied thermal assessments perform one-dimensional heat transfer analysis over planar elements such as the facades studied in this experiment. However, it is well known that thermal bridges are locations in buildings where one-dimensional heat transfer analysis cannot be applied. This problem was approached by creating a numerical 2D thermal model which was calibrated against experimental data from several temperature and heat flux sensors which were located at specific points in the thermal bridge elements.Government of the Basque Countr

Poster STUDY ON THE EFFECT OF SOL-GEL PARAMETERS ON THE SIZE AND MORPHOLOGY OF SILICA MICROCAPSULES CONTAINING DIFFERENT ORGANIC COMPOUNDS

Microcapsules can be considered as small containers filled of active compounds that depending on the final application can contain a very wide range of different materials. In the last years the importance of silica microcapsules has grown considerably due to their great chemical resistance, thermal stability, biocompatibility and environmental-friendliness. 1 Silica microcapsules with diameters in the range of nano, micro, and in some cases almost in the millimetre scale containing different organic compounds have been synthesized combining the sol-gel chemistry with the oil in water microemulsion technology. 2 In the current study we have observed that variations in the pH of the reaction during the hydrolysis step, modifications in the silica/water ratio, or even the nature of the encapsulated organic compound, have dramatic effects in the type of shell obtained, the morphology and also in the particle size distribution.
