Formerly the IBM tower, this 41-story office facility began a long-term capital plan to retrofit the building automation system in 1994. With 24 elevators, over 1,000,000 square feet, and a large public atrium on the ground level, the building demanded an automated system needing as little user-input as possible. In collaboration with Cosentini Associates, TEC Systems proposed and installed a fully integrated system engineered to the American Auto-Matrix (AAM) building-controls standard. At one point the largest AAM installation in the world, the project was further complemented with Echelon’s LonPoint modular system, and open and interoperable control device. Spread throughout the structure to manage every aspect of building functionality, the system is fully monitored and maintained by just 4 user workstations. That’s user-friendly.
