Abstract:

Corrugated zinc roofs in residential buildings in humid tropical areas often create high temperatures in the dry season and noise in the rainy season. This research is a comparative experiment that analyzes the difference in thermal and acoustic performance between two spaces with different types of roofs, i.e., conventional corrugated zinc roofs, and corrugated zinc roofs with green roof systems. The results showed that the difference in temperature fluctuations on green roofs was recorded at 4.40°C lower than conventional roofs, which reached 9.00°C. Meanwhile, the difference in relative humidity fluctuations was recorded as 7.31% lower on green roofs. The lowest noise level during rain was also recorded on green roofs, which was 48.85 dBA, indicating that the noise level is still within the tolerable range for acoustic comfort in residential buildings in urban areas. In comparison, conventional roofs show the lowest noise levels of 55.15 dBA. Therefore, green roofs can be an alternative roofing material that supports the creation of comfortable spaces in humid tropical regions.
