The aim of this research is to investigate the viability of designing urban rooftop soundscapes. The prerequisite is to reduce the sound propagation from road traffic by introducing living architectural rooftops with various components of sound attenuating technologies. The final goal is to turn unused rooftop space into a livable urban green space, where soundscape is balanced, and sound energy is reduced to the limits recommended by the World Health Organization (WHO). The first part of this research is to identify the potential of living architectural technologies to attenuate noise from road traffic. More than 33 measurements are performed of living architecture design tools, such as green roofs, berms at edge, living wall barriers and overhangs, to investigate the behavior of sound attenuation in an anechoic chamber and in ODEON, a computer simulation software. The second part of this research is to use the findings on the proposed design tools for an architectural case study, a flat-roof five-storey building located on East Hastings Street. The use of a combination of green roof, berm, overhang, guard and living wall can reduced urban traffic noise from 70 dBA on the roof to 55 dBA, creating additional acoustically healthy habitable space in the urban environment.
