disclosed, nor represents that its use would not infringe privately owned rights. The
models described in this report are intended to demonstrate the potential thermal and
air flow patterns of possible energy improvements for the new facilities. Due to the
limitation of the Computational Dynamics Analysis including differences of physical
models and the real world, boundary conditions, and numerical errors, the
conclusions of this report do not guarantee actual thermal and air flow profiles or
system performances.
