Your facility has a watt-hour meter that you can read and
record manually.

For single devices or wall outlets, the simplest measurement
is probably a kill-a-watt or one of its clones.This will
record energy consumed since a last buttom-press or application
of input power.

First order approximation for real datalogging is a record
of current, stored on a portable PC. Multimeters with PC
interface are becoming fairly inexpensive, to make this
measurement - software to record and manipulate data may be
slightly buggy or poorly supported.

Haven't seen a really cheap datalogger, but haven't looked
lately. These will also mant to interface to a PC for
data recording analysis and display.
