For Thomas Marino, president of Advanced Technologies, Baton Rouge, La., “green” projects were nothing new. He had done projects that involved low-power, solar or other green elements. But when he ran into local attorney Joe Simmons at a trade show, the extremely environmentally conscious lawyer asked him to do the security and home automation for the custom home he was building. The home was new construction in a community of older homes and would feature as many green elements as possible, from the material in the countertops to the security and audio elements.
