Using Numerical Stochastic Perturbation Theory within three-dimensional pureSU(3) gauge theory, we estimate the last unknown renormalization constant thatis needed for converting the vacuum energy density of this model from latticeregularization to the MSbar scheme. Making use of a previous non-perturbativelattice measurement of the plaquette expectation value in three dimensions,this allows us to approximate the first non-perturbative coefficient thatappears in the weak-coupling expansion of hot QCD pressure.Comment: 16 pages. v2: published versio
