A model of hard-core bosons on a three-dimensional (3D) lattice has been studied using both quantum Monte Carlo and classical Monte Carlo techniques. We have calculated the transition temperature for Bose-Einstein condensation, the zero-temperature penetration depth and the specific-heat critical amplitude, and have explored the hyperuniversal scaling relationship between these quantities pertaining to the expected 3D {ital XY} critical point. As a conclusion we draw a phenomenological analogy between the model studied and extreme type-II superconductors. {copyright} {ital 1996 The American Physical Society.}
