| This work examines the relationship between building material longevity, maintenance and life cycle environmental impact. Models for material and system maintenance and replacement over the life of a building have not been widely used in building life cycle assessment studies. This work has developed service life models for buildings that feature life cycle impact assessment metrics. The results of such building life cycle assessment analyses are anticipated to produce variation in accordance with the different service life intervals, and cumulative maintenance activities over time. A total of thirty-six roof and wall combinations have been modeled, using five alternative service life models. The results have been characterized with respect to Global Warming Potential, Atmospheric Ecotoxicity and Atmospheric Acidification as defined by the Tool for Reduction and Assessment of Chemical and other Environmental Impacts (TRACI). |
