Zero Point Energy

    I have a layman's understanding of the subject of ZPE, but one thing i can't wrap my head around is one claim hear a lot in many of the articles i'm reading; that the ZPE field is throughout all of space. With my understanding of quantum mechanics, and study of the particle in the box, as well as the harmonic oscillator, I understand the fact that a particle must always have an inherent energy, and that energy can never be zero. My question is basically, why must the vacuum have an energy as well? A vacuum is the absence of any matter, so why must it be expected to have an energy?
