Life Cycle Analysis: Buildings -2013

2013

Abstract

A lifecycle analysis for four case studies was carried out: an auditorium, a residential building, a hospital and an office building. For every case two scenarios were modeled: one conventional, which consists on the construction and operation of a building under the most common standards among its kind, and one efficient, consisting on adapting (or restructuring) existing buildings and operation with outstanding technologies for their efficiency. For each building and scenario we analyzed the potential environmental impacts associated with the extraction, manufacturing and transportation of materials, construction of the building and their occupation during fifty years. Significant differences were found between scenarios in which we recognized that adapting buildings has important environmental benefits on all stages of its life cycle. Depending on the category of impact analyzed and the type of building, we observed that adapting buildings may reduce impacts by 32% or up to 94%. In the study we also identified the main flows on which there is little national data available and those where further research should be delved into.
