By merging single-site typical medium theory with density-functional theory, we introduce a self-consistent framework for electronic-structure calculations of materials with substitutional disorder which takes into account Anderson localization. The scheme and details of the implementation are presented and applied to the hypothetical alloy Li c Be 1−c , and the results are compared with those obtained with the coherent potential approximation. Furthermore, we demonstrate that Anderson
