[Taxacom] Compactus and gain in storage space

[Rabeler, Richard]

Doug gives a very good explanation of how one might approximate such a gain.

When we installed a compactor at the University of Michigan Herbarium quite a few years back, we gained 75% measured in the # of additional standard cabinets that could now be placed in that space.  In our case, 16 standard aisles were replaced with 4.

This is easy to calculate: the primary function of a compactor system
is to eliminate the aisles between storage units. If you plan to
retain the same storage units, then the space you will gain is almost
exactly equal to the space occupied by the aisles you will lose (if
installing a single continuous bank of compactor units, then you'll
keep only one aisle from the original N, and lose N-1). Only a few
inches are needed between adjacent closed compactor units. The wider
the aisles relative to the storage space, and the more of them in the
original floor plan, the bigger the percentage gain in space. Since
those are variables depending on the kind of storage units, and
quirks of architecture, there is no good "rough" number one can use
to generalize, though I can't imagine it would ever equal or exceed
double (i.e., 100% increase) the original capacity (that would
require that *over* half the original floor space was empty aisles).
Figures that high are generally only possible when either additional
floor space is included in the compactor "footprint" or when the
storage units themselves are replaced with more space-efficient units.
