Honeywell International Inc. once again delivered solid results in the second quarter of 2025, with particularly impressive performance in the building automation segment thanks to technology-driven growth. Revenue and profit figures significantly exceeded analysts’ expectations, with a particular focus on integrated automation solutions, digitally connected building technology and energy-efficient systems.
Technology-driven growth in building automation
The building automation segment achieved revenue of $1.83 billion, representing an increase of +16.2% compared to the previous year.
This clearly exceeded the analyst consensus of 1.75 billion US dollars. Segment profit was 479 million US dollars, significantly above the average analyst estimate of 459 million US dollars. Honeywell is benefiting in particular from the growing demand for scalable, IoT-based solutions for building automation.
These include:
- Intelligent HVAC control systems with predictive maintenance
- Building monitoring systems with AI-supported anomaly detection
- Cloud-based integration platforms for multi-building management
- Energy optimisation and CO₂ monitoring solutions in the context of ESG
These systems support both new construction and retrofit projects in existing properties – a decisive factor in the highly competitive market environment.
Segment development in technical comparison
| Business Segment | Revenue Q2/25 | YoY Development | Analyst Forecast | Segment Profit |
|---|---|---|---|---|
| Building Automation | $1.83 billion | +16.2% | $1.75 billion | $479 million |
| Industrial Automation | $2.38 billion | -5% | $2.24 billion | $456 million |
| Aerospace Technologies | $4.31 billion | +10.7% | $4.33 billion | $1.1 billion |
| Energy & Sustainability Solutions | $1.84 billion | +14.5% | $1.67 billion | $443 million |
Building Automation is not only showing strong growth, but is also highly profitable – particularly thanks to modular system architectures, real-time edge computing and increasing standardisation (e.g. BACnet, KNX, Modbus, MQTT).
Technological focus areas & strategic implications
This development illustrates Honeywell’s focus on interoperable system solutions to maximise energy efficiency, automation and data transparency in buildings. Particularly relevant in the context of technical developments are:
- Forge platform: Cloud-based analytics and control across all buildings
- Cybersecure Building Networks: Integrative security solutions for OT and IT levels
- Digital twin concepts: Virtual real-time mapping of complex building infrastructures
- Interfaces to EMS/BMS systems: Simplification of integration into existing environments
In addition, Honeywell is an active driver of standardisation work in the field of intelligent building automation and participates in international initiatives such as ASHRAE, IEC 63252 and Open Smart Building Alliance.
Conclusion for specialist planners and system integrators
The second quarter of 2025 underscores Honeywell’s role as a technology leader in building technologies. The combination of end-to-end system integration, high compatibility with common industry standards and a focus on ESG-compliant efficiency solutions makes the portfolio highly attractive to technical decision-makers in planning, operation and modernisation.
Against the backdrop of growing regulatory requirements in Europe, North America and Asia, the importance of holistic, data-driven building automation is likely to increase further – with Honeywell as one of the key players in the industry.
