  The purpose of this paper is to resolve a question regarding efficiency of a
lightning protection system (LPS) for buildings based on the collection volume
method (CVM) . The paper has two components. The first, following suggestions
of other authors [Abidin and Ibrahim 2004], takes advantage of count data from
installed devices, and independent installation-site inspections to develop our
statistical analysis. The second component investigates the validity of the
underlying theory by introducing a novel methodology of fractional Poisson
processes, which are able to reproduce the burstiness of lightning strikes, an
essential feature of stochastic time dependence of incidence of lightning
strikes. The standard Poisson processes used in the past efforts in this area
cannot do that.
