[TRNSYS-users] Electricity load scheduling for a household.

[David BRADLEY]

Elias,
  There are two components in the TESS Utility library that will choose 
a random number. Type578 gets a random number from a normal 
distribution. Type577 generates a random number from a "uniform" 
distribution.
Best,
  David
