Help with sampling!!!

Hello guys!

I intend to use Grasshopper  to do parametric simulations to model energy performance using the plug in DIVA (that runs Energyplus).  However, my universe of models is too large, so I was wondering if there is any way to use ANY Sampling method, so grasshopper doens't need to produce every model and I can run the energy simulation just for the sampled models.

I don't want to use Galápagos, since my goal is not to obtain the model with the best performance, but to obtain a universe of models that represent my entirely set.

Does anybody know if it is possible, or if there is any plugin that is able to do that?

Thank you very much!!!
