Method and system for controlling a selected electrical load in a building

In a system including a plurality of energy dissipating loads a method for controlling from a location remote from a load of said plurality of loads the amount of electrical energy applied to said load wherein load control information is transmitted between said remote location and said load by way of a plurality of electrical energy transmission lines including a neutral conductor, a ground conductor and a line conductor, comprising the steps of:

• (a) determining load control information representative of said energy applied to said load;
• (b) applying said load control information to said energy transmission lines at an impressing end of said energy transmission lines for transmission to a receiving end of said energy transmission lines wherein said load control information is impressed between said neutral conductor and said ground conductor of said energy transmission lines to provide impressed load control information;
• (c) receiving said impressed load control information at said receiving end of said energy transmission lines by obtaining said load control information from between said neutral conductor and said ground conductor to provide received load control information;
• and
• (d) controlling said energy of said load in accordance with said received load control information.
