Embodied vs. operational energy and carbon in retail building shells: a case study in Portugal
(1) Background: The embodied energy of building materials is a significant contributor to climate change, in tandem with the energy use intensity (EUI). Yet, studies on the material impacts of European retail buildings, namely with relation to EUI, are missing. Hence, this study set out to: (i) evaluate the embodied energy and carbon emissions for a European retail building; (ii) quantify the material flow in terms of mass; (iii) compare the embodied aspects to the operational EUI and carbon use intensity (CUI); (iv) assess building materials with higher impacts; and (v) investigate strategies to mitigate materials’ impacts. (2) Methods: A Portuguese retail building was selected as a case study. A simplified LCA method was followed (cradle-to-gate), analysing the shell building materials in terms of primary energy demand and global warming potential. (3) Results: the embodied energy represented 32% of total lifecycle energy while the embodied carbon represented 94%. EUI was 1×kWh/m 2 /y while CUI was 21 kg CO 2 eq/m 2 /y. The embodied energy was 4248 kWh/m 2 , and the embodied carbon was 1689 kg CO 2 eq/m 2 . Cement mortar, steel, concrete, and extruded polystyrene were the most intensive materials. (4) Conclusions: The embodied impacts of the analysed store could decrease by choosing stone wool sandwich panels for the facades instead of extruded polystyrene panels and roof systems with metal sheet coverings instead of bitumen materials. ; This research was funded by FCT—Fundação para a Ciência e Tecnologia (grant number PD/BD/127852/2016) under the Doctoral Program EcoCoRe—Eco-Construction and Rehabilitation. Support from CERIS and Instituto Superior Técnico is also acknowledged.
