Inspired by this question we ask the following question:



Is there a complete classification of all unital $C^*$ algebra $A$ for which the following subalgebra $B$ is a von Neumann algebra? Is there a terminology for such kind of $C^*$ algebras?



$$B=text{The unital $C^*$ sub algebra generated by all projections of $A$} $$



Of course every von neumann algebra satisfies this property.
