Abstract: In a previous paper a method was proposed to find exact analytic solutions
of open string field theory describing lower dimensional lumps, by incorporating in string
field theory an exact renormalization group flow generated by a relevant operator in a
worldsheet CFT. In this paper we compute the energy of one such solution, which is
expected to represent a D24 brane. We show, both numerically and analytically, that its value corresponds to the theoretically expected one
