Abstract

This paper aims at advancing on the validation of indicators for sustainabilityevaluation of concrete building structures from an integrated life cycle perspective. A case studyapproach investigates (i) the feasibility of comparing sustainability performance of differentconcrete slab systems; and (ii) the similarity between environmental indicators trends for atypical floor and the corresponding whole superstructure. Thirty‐one vertical buildings areanalyzed, five of which are commercial and twenty‐six residential buildings, using eitherprestressed or reinforced concrete slabs with or without beams exposed to a marineenvironment. SimaPro 7.3 supports calculation of the environmental indicators. Service lifeestimation is used to ensure functional equivalence and to form a basis for life cycle costing.Analytic Hierarchy Process was used to establish relative importance among indicators. PCF slabsshowed best functional‐technical and economic results, while no particular trend amongprestressed and reinforced concrete slabs was observed concerning environmental results.
