LCA on case study – concrete : FA 1 Environmentally friendly concrete : SP Insulating and energy preserving concrete

The aim of this study, using LCA, is to 1) Assess CO₂ emissions and embedded energy of a passive house roof construction, and 2) Identify the concrete with the lowest emissions and energy use The goal of this analysis was to find out, by applying the LCA methodology, the embedded energy and GHG emissions of 1 m2 concrete roof. Further focus has been to look at consequences attached to the use of different types of cement in the concrete. The three different types of cement analysed is Portland-cement taken from the Ecoinvent database, Standard cement from Norcem and Low Carbon cement from Norcem. The results show that concrete based on the low carbon concrete has the lowest embedded energy and GHG emissions. Kari Sørnes and Torhildur Kristjansdottir at SINTEF have contributed to the work presented in this report through the VISES(...) project. In COIN 2011 we have limited the study to a cradle-to-gate study. Maintenance, service life and end of life will be treated in COIN 2012.
