Research: Embodied CO2 of structural frames
This paper discusses a study undertaken by Arup on behalf of The Concrete Centre to investigate the embodied CO2 in typical structural frames for non-residential buildings. The study used the designed and measured schemes produced for the cost model studies published by The Concrete Centre in 2007-2008. The study explored the variations in embodied CO2 predictions. Two sources of variation were considered: the method of the analysis and the speciifcation. The study found that, within the uncertainties of the available data, there was little difference between the embodied CO2 of the different types of structural frames, but that once the frame type had been chosen, there was a significant opportunity for the structural engineer to reduce the embodied CO2 of the final structure by careful specification.
