Gravitational waves (GW) from coalescing stellar-mass black hole binaries(BBH) are expected to be detected by the Advanced Laser InterferometerGravitational-wave Observatory and Advanced Virgo. Detection searches operateby matched-filtering the detector data using a bank of waveform templates.Traditionally, template banks for BBH are constructed from intermediaryanalytical waveform models which are calibrated against numerical relativitysimulations and which can be aluated for any choice of BBH parameters. Thispaper explores an alternative to the traditional approach, namely theconstruction of template banks directly from numerical BBH simulations. Usingnon-spinning BBH systems as an example, we demonstrate which regions of themass-parameter plane can be covered with existing numerical BBH waveforms. Weestimate the required number and required length of BBH simulations to coverthe entire non-spinning BBH parameter plane up to mass-ratio 10, thusillustrating that our approach can be used to guide parameter placement offuture numerical simulations. We derive error bounds which are independent ofanalytical waveform models; therefore, our formalism can be used toindependently test the accuracy of such waveform models. The resulting templatebanks are suitable for advanced LIGO searches.
