Johnson Controls

Johnson Controls International plc (NYSE: JCI) stands as the world's preeminent authority in smart, healthy, and sustainable buildings, serving customers across more than 150 countries with a team of 100,000 experts. Founded in 1885 when Professor Warren Johnson invented the first electric room thermostat, the company has evolved from a temperature control innovator into a comprehensive building technology powerhouse with nearly 140 years of engineering excellence and innovation.

Headquartered in Cork, Ireland, with significant operations in Milwaukee, Wisconsin, Johnson Controls delivers the world's largest portfolio of building technology, software, and service solutions with annual revenue of $27.4 billion (fiscal 2024). The company's transformation accelerated following major strategic moves, including the 2016 merger with Tyco International and the 2019 divestiture of its automotive business, positioning it as a pure-play building solutions provider.

At the heart of Johnson Controls' offering is OpenBlue, an AI-powered smart building ecosystem that connects HVAC, fire, security, and control systems on a single platform. Recognized as an IoT digital platform leader by Verdantix, OpenBlue delivers measurable outcomes: up to 30% reduction in energy spend, 20% reduction in maintenance costs, and 10% improvement in space utilization. The platform's AI capabilities, significantly expanded in 2024, enable autonomous building controls and generative AI applications that automatically optimize setpoints and analyze energy usage based on real-time weather data.

Johnson Controls serves a diverse customer base spanning commercial real estate, data centers, healthcare facilities, educational institutions, and industrial complexes. The company's product portfolio includes residential and commercial HVAC equipment under brands like YORK (celebrating its 150th anniversary in 2025), industrial refrigeration systems, building automation through the Metasys platform, security systems, and fire detection and suppression solutions. With a building solutions backlog of $13.1 billion and North American orders growing 18% in fiscal Q1 2025, the company demonstrates strong momentum in capturing demand for smarter, more sustainable buildings.

The company's commitment to sustainability extends beyond its products to its own operations. The Cork headquarters at One Albert Quay, a 170,000 square-foot facility housing employees from 27 nationalities, features an OpenBlue Innovation Centre focused on developing next-generation sustainability solutions. Johnson Controls was named to Fortune's 2025 Change the World list for its breakthrough data center cooling innovations, specifically the YORK YVAM Air-Cooled Magnetic Bearing Chiller, which addresses the critical challenge of thermal management in AI-driven data centers.
