While the reduction of operational energy and associated emissions has been the focus of the building design community in recent decades, focus must now begiven to reducing the upfront or embodied energy and emissions of buildings. Embodied energy and emissions are those associated with the extraction,manufacturing, transportation, and end-of-life of building materials and assemblies. The present study evaluates, using life cycle assessment, the “cradle-togate”embodied energy and embodied carbon of the Office and Apartment ASHRAE 90.1-2016 DOE Prototype Buildings. Results from this analysisshow that on average, the office prototype buildings consumed 938 MJ/m2 (82.6 kBtu/ft2) of embodied energy and emitted 77.0 kg CO2e/m2(15.7 lbCO2e/ft2) of embodied carbon. The apartment prototype buildings consumed 1168 MJ/m2 (103 kBtu/ft2) of embodied energy and emitted 102 kgCO2e/m2 (20.9 lb CO2e/ft2) of embodied carbon on average. This study serves as a first step towards establishing reference building models for embodiedcarbon so that the building design community can realize a zero-carbon built environment by 2050.
