Thermal performance effect of hollow ceramic micro-spheres coating assessed by dynamic outdoor testing in the summer season

Popis výsledku v původním jazyce

The paper presents the results of a comparative study investigating the thermal performance of coatings containing hollow ceramic microspheres, as regards their impact upon the energy balance of buildings during the summer period. This research has been inspired by the intention to reduce the costs of heating and cooling of buildings by using appropriate combinations of various surface coating modifications and verifying their features guaranteed by manufacturers. There are both expectations and doubts that have not yet been properly investigated in many cases. At the present day the building industries are already aware of more precise evaluation and measurement methods that are not yet commonly used in the area of building physics. We decided to investigate the thermal performance of the external building coatings by way of the Twin-Box method that is suitable for outdoor dynamic testing. Samples were prepared, and namely the coating of micro-spheres base to be compared and a standard facing for reference. The measured data testify to the difference of spectral reflectance properties as well as thermal performance effects made up app. 5% in comparison of the standard façade coatings of an identical color shade. The samples were monitored by dynamic outdoor testing especially under clear sky daytime conditions. The spectral reflectance properties in the region of visible and shortwave radiation were assessed by spectroscopy methods. Both used methods were finally confronted.
