ABSTRACT

Building life-cycle assessments should consider both sustainability and hazard vulnerability. This paper presents an innovative building life-cycle assessment framework quantifying environmental metrics and economic indicators of building performance, while accounting for potential risk of hazard events. The framework outlines interactions between building design and modeling, structural and environmental analysis, and life-cycle analysis. A lifecycle assessment of a commercial building in California, designed with and without a green roof, illustrates this methodology. Nonlinear analysis under earthquake ground motions assesses the seismic vulnerability of the structures through probabilistic loss estimation of required repairs. Environmental analysis quantifies building impacts in terms of fossil fuel consumption and climate change potential. The case study findings offer insight into the effects of seismic hazard performance on building environmental impact.
