In this paper, we give a proof of certain finiteness results about split Kac-Moody groups over a local non-archimedian field. Our results generalize those of "An affine Gindikin-Karpelevich formula" of Alexander Braverman, Howard Garland, David Kazh-dan and Manish Patnaik. We do not require our groups to be affine. We use the hovel I associated to this situation, which is the analogue of the Bruhat-Tits building for a reductive group.
