As an energy auditor, Sam visits buildings to look for master vents and conduct a forensic investigation of worn-out nameplates. He then scours the utility bills and analyzes the potential utility savings based on operational or equipment changes, enticing people to reduce energy consumption with the lure of saving money. Much of his work has supported National Grid customers through their Energy Efficiency Program, and he has had the satisfaction of, among other things, seeing a large pharmaceuticals-manufacturing facility implement his efficiency recommendations.
