Thermal behavior of masonry building fence to brazilian climate zone 2

ABSTRACT

This work aims to evaluate a case study of thermal behavior of ceramic and concrete block masonry fences for Brazilian climate zone two. In-place measurements of outside and inside temperature were carried out to obtain the influence of the fences built with ceramic or concrete block. The buildings are localized in the same position at the city of São Leopoldo-RS. The measurements were taken in two periods in winter and summer, using temperature recorders placed on the second floor and rooftop. There were analyzed the influences of three variables on thermal behavior: type of block, solar orientation and the thermal gains of the roof. As a conclusion of this research, it was observed a small difference in the internal temperature for both building in winter and summer, indicating a little influence of the type of the block on the thermical behavior of the fences. The highest temperatures and the lower thermal damping occurred in winter for the walls with higher solar incidence to north and, for summer, for the blind south wall, emphasizing the importance of the solar radiation incidence for the opaque fences. It was obtained in winter and summer a high temperature and a wider thermal range for the roof.
