  ABSTRACT: In this paper, we introduce a new type of graph energy called the non-common-neighborhood energy ,,NCN-energy for some standard graphs is obtained and an upper bound for is found when G is a strongly regular graph. Also the relation between common neigh-bourhood energy and non-common neighbourhood energy of a graph is established.
