Sustainability is a concept created by the environmental scientists in the 1980s and has a significant impact on building design. At first glance, sustainability can be understood as the uninterrupted continuation of the benefits as they were designed throughout the life of the buildings. In addition, it can be considered as the ability of the building to continue its function without disrupting the design purpose in the event of facing natural disasters such as earthquakes. The importance of the concept of sustainability is more remarkable especially in geographies where the seismicity is high. By making use of seismic isolation as an earthquake-resistant design method, post-earthquake sustainability can be easily realized as it allows to practically achieve the uninterrupted performance level after a major earthquake. Aside from earthquake resilience, a sustainable building design should also consider other aspects such as effective energy use, effective water management, and effective heating and cooling and aim to reduce the burden of these systems in terms of costs by using natural resources in the most efficient way. Green roof systems are among the main elements of sustainable building design, which absorbs rainwater, creates a habitat, provides insulation, and decreases the stress of the people around the roof by providing a landscape, and helps to lower urban air temperatures. Within the scope of this study, as a sustainable building example that takes both earthquake and environmental issues into account, a benchmark base-isolated building with a green roof system is described and its seismic performance under a historical near-fault earthquake record is compared to its fixed-base counterpart. Nonlinear time history analyses are carried out to obtain main structural response parameters including inter-story drifts, floor accelerations, and story shears which directly relates to sustainability. Comparisons are carried out in terms of the aforementioned structural response parameters.
