Abstract

In this study, thermal performance comparison of green roofs and shingle roofs is carried out based on experimental and theoretical analyses with the purpose of focusing on urban sustainability in residential areas. Roof systems were built at three slope angles: 1˚, 20˚, and 40˚. Differences in the average temperature of the undersides of the roof decks were measured and compared between green roof models and shingle roof models at these different slope angles. Experimental data was recorded for three summer months to compare the cooling load difference of both roof types. A case study was conducted on a residential single-story unit in Santiago, Chile. Results showed that a residential green roof system can yield significant energy savings in the summer season due to enhanced thermal insulation. This would lead to a noticeable reduction in carbon footprints for urban areas, contributing to a more sustainable environment.
