This thesis aims to illustrate how environmental impact can be reduced, through the use of lean concrete. It also illustrates how environmental data can be applied to a house through implementation with BIM. In this study a unique concrete structure developed by Swedish Cement and Concrete Research Institute is assessed for environmental impact, by calculating the carbon dioxide equivalents using LCA methodology. The construction is a sandwich element where the concrete is made up of three layers. Two external high-strength layers and a middle layer of low-strength concrete. The result is compared with three different concrete recipes. The environmental data obtained is then integrated with a building model in the BIM tool Autodesk Revit, using an own developed method. The purpose is to perform a sensitivity analysis in which the bearing walls are replaced with these concrete recipes. By performing a sensitivity analysis the effect the concrete has on an entire building can be seen. The result shows that there are major differences between the concretes. By only replacing the bearing interior walls to greener alternatives of the same material the climate impact is reduced by 10% of the building's overall climate impact. This study also shows that the resource efficient concrete has a lower climate impact than a standard concrete of the same strength class. The advantage is that this type wall construction can be made thicker without getting a significantly higher climate impact.
