Effect of Covers Terraces on Humidity Inside Buildings: Case Study in the City of Rabat

Abstract

Covers terraces are becoming increasingly widespread, given their advantages in terms of regulating the building's climate and the speed at which rainwater runs off. The first article in this research consisted in selecting plantations capable of withstanding the conditions of terraces, while the second article dealt with the effect of terrace coverings on the temperature inside buildings. Although sedums are the most widely used plant species for covering building terraces and have shown the best resilience and adaptability for green roofs, additional ecosystem services can be provided by native plants, suggesting future research to optimize plant composition and cover for sustainable green roofs. This research compares the effect of terrace coverings of different thicknesses on humidity inside buildings. This research compares the effect of terrace covers with different thicknesses (5 cm and 10 cm), on humidity inside buildings during the four seasons. The results show that the 10 cm thick terrace cover has a humidity-increases effect during the warm period (+ 3,01%). The 5 cm thick terrace cover has a humidity-reducing effect during the cold period (-0,2%). Also, the maximum relative humidity of the 10 cm thick cover decreased by 9.48%, and the maximum relative humidity of the 5 cm thick cover decreased by 13.25%.
