Field Measurement of Surface Temperature at Building Faade with Louver Blinds

Abstract:

A field measurement was conducted on to a real building for temperature distribution at its faade and louver blinds in this paper. Halfhourly surface temperature distribution of louver blinds, louvered faade and unlouvered faade were performed by this measurement. From this data, a conclusion on maximum temperature difference (about 10 ℃) between louver blinds and louvered faade was reached. Besides, the surface temperature at louvered facade was compared with that at an unlouvered one. Based on the measurement above, the effect of louver blinds on convective and longwave radiative heat transfer at building faade was briefly analyzed, and the importance to correctly describe these two process was pointed out.
