Thermal performance analyzing of hollow microspheres coatings for building energy efficiency

abstract

English

The main objective of this study resides in investigating the optical properties and thermodynamic aspects of coatings that are based upon hollow ceramic microspheres (HCM), as compared predominantly with the standard façade coatings. Both laboratory and full scale tests were conducted in order to analyze non-steady state heat transfer monitoring through samples. Similarly all external radiation impacts on highly insolated and weakly isolated walls were involved in experimental surveys. Testing periods represented clear sky conditions in a mild climate zone. The results of spectral analysis demonstrate that within the infrared region, however, both in the near and the longwave one, compared coatings can be assessed as having almost identical reflective properties. As regards in a visible region, both have very negligible differences. On the full scale tests level, the final results allow formulating a conclusion that the coatings based upon ceramic microspheres can contribute to positive energetic effect due to reducing cooling loads at the low level as in comparison of the standard façade coatings of an identical colour shade, which in other words does not represent significant benefit in current standards of building envelopes for building energy efficiency of mild climate zone, as it was demonstrated on highly insolated and weakly isolated vertical components.
