Americas also provides energy efficiency solutions and technical services, including inspection, scheduled maintenance, and repair and replacement of mechanical and control systems, as well as data-driven "smart building" solutions, to the Americas marketplace.
•EMEA, which designs, manufactures sells, installs and services HVAC, controls, building management, refrigeration, integrated electronic security systems, integrated fire detection and suppression systems, and digital (software) solutions for commercial, residential security (Global Subscriber business), industrial, data center, institutional, governmental, and marine customers and provides technical services, including data-driven “smart building” solutions, to markets in Europe, the Middle East and Africa.
