   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.
