• Scalability: It’s ideal for applications ranging from small to medium-sized systems, and its expandability makes it a good choice for gradual upgrades in legacy buildings. 

This controller excels at integrating existing systems with new smart building technology, ensuring that older infrastructures can be modernised with minimal disruption. The JACE 8000 is also equipped to handle intelligent HVAC systems, making it a great fit for optimising building energy consumption and supporting energy-efficient buildings. 

JACE 9000: The Future of Building Automation 

The JACE 9000 takes the capabilities of the JACE 8000 to the next level, offering enhanced performance and future-proofing for IoT building automation systems. With a quad-core processor and double the storage and RAM compared to the JACE 8000, the JACE 9000 is built to support larger, more complex integrations. 

Key features include: 

• Quad-Core Processor for faster boot times and quicker system loads 

• Enhanced Security: Secure boot, HSM authentication, and encrypted communications for robust protection 

• Scalable Licensing: From 100 to 10,000+ data points, with easy upgrades as your system grows 

• Modular Design: Can expand with up to four additional ports, including LonWorks, RS232, and RS485 

Ideal for smart building technology and intelligent HVAC systems, the JACE 9000 ensures that your building is ready for future advancements in automation. It’s designed to manage large-scale, data-driven environments, providing more power for demanding applications and integrating seamlessly with modern systems. 

The JACE 9000 is also an excellent choice for legacy building modernisation, enabling incremental upgrades while maintaining compatibility with older equipment. This makes it the perfect option for properties looking to evolve into energy-efficient buildings without starting from scratch. 

Legacy System Modernisation and Smart Buildings 

When choosing between the JACE 8000 and JACE 9000, one of the most important considerations is how they support both legacy building modernisation and new smart building technology. While the JACE 8000 offers compatibility with older systems, the JACE 9000 is better equipped to handle the complexities of modern smart buildings. 

For properties seeking to improve their energy-efficient buildings, the JACE 9000 provides more processing power and future-proof compatibility, allowing for more sophisticated building management systems. This ensures that as your system grows, it can handle increased data loads and support the integration of advanced technologies. 

The JACE 9000 is designed to be adaptable to both legacy infrastructures and cutting-edge systems, making it ideal for phased upgrades that introduce smart building technology without disrupting existing operations. 

As the JACE 8000 approaches End of Life—with support ending in December 2025 for Europe and December 2026 globally—now is the time to upgrade to a platform built for tomorrow’s demands. The JACE 9000 delivers the same trusted connectivity but with significantly faster performance, enhanced security, and forward compatibility, making it an intelligent choice for building owners, facility managers, and integrators. 

By choosing the JACE 9000, you’re not just replacing hardware—you’re future-proofing your building management system for a more connected, efficient, and scalable tomorrow. 

Conclusion  

Both the JACE 8000 and JACE 9000 offer reliable solutions for IoT building automation systems. While the JACE 8000 serves well for smaller or existing building management systems requiring incremental upgrades, the JACE 9000 provides the enhanced scalability, speed, and security necessary to support larger, more complex smart building environments.  

Choosing the JACE 9000 means investing in a future-proof platform designed to accommodate growth and innovation. It allows building owners, facility managers, and integrators to seamlessly integrate new technologies while maintaining compatibility with existing systems. This makes the JACE 9000 the smart choice for those looking to create connected, efficient, and scalable building management systems that can adapt to tomorrow’s challenges.
