Johnson Controls has completed a landmark project to power the southern hemisphere’s tallest building with green technology, reducing energy use by up to 30 per cent.

Thamrin Nine is a flagship multi-purpose complex in central Jakarta’s central business district that spans commercial, hospitality and retail spaces. The project, which helps reduce energy use by up to 30 per cent, recently achieved BCA (Building & Construction Authority) Green Mark Platinum certification, recognising its environmental performance.

As part of the project, Johnson Controls provided chiller plant design and implementation, engineering services and building automation systems for two of Thamrin Nine’s skyscrapers – the Autograph Tower, the tallest building in the Southern Hemisphere at 382.9 metres, and the Luminary Tower. With building systems fully deployed across both towers, Johnson Controls will continue supporting the development through ongoing service and maintenance to ensure long-term efficiency and comfort, and enhance equipment lifespan.

Johnson Controls designed, supplied and installed a suite of integrated building technology tailored to the complex’s high-performance needs. Thamrin Nine marks the company’s first chiller plant optimisation project in Indonesia, which aims to make cooling systems work smarter through technologies and improved operations. Through turnkey project management that covered design, implementation and integration across systems, Johnson Controls was able to deliver significant energy and cost savings. These included:

• A 3100-ton York cooling system for Autograph Tower, designed to meet the Green Mark Platinum certification target of below 0.58kW/TR. The system helps reduce energy use by up to 30 per cent, supporting lower operating costs while maintaining comfort across the building.
• Three 300 TR high-efficiency York chillers integrated with an energy management system (EMS) optimising cooling performance and reducing energy demand in the Luminary Tower, which houses three hospitality properties.
• Tailored air handling units (AHUs) and fan coil units (FCUs) for diverse commercial, retail, residential and hospitality zones.
• Analytics and real-time monitoring based on Metasys building management system, enabling facility teams to detect and resolve issues before downtime occurs and improving reliability and reducing maintenance costs.

“This project is a defining milestone for urban development in Jakarta,” said Michael Wiener, design director at Thamrin Nine. “Our goal was to change the way people live, work and play in Jakarta, delivering an integrated destination that combines scale, choice, convenience and sustainability. Johnson Controls has been the ideal partner to help us achieve that vision, and we appreciate their continued support in maintaining performance at the highest standards.”

Wibawa Jati Kusuma, general manager for Malaysia and Indonesia at Johnson Controls (johnsoncontrols.com), added: “Our partnership with Thamrin Nine exemplifies how future-forward engineering and digital optimisation can deliver not just iconic buildings, but greener, smarter cities. By integrating advanced building technologies, we’re creating healthier, more sustainable indoor environments that reduce operational costs, lower carbon emissions and enhance occupant well-being. With ongoing service and support, we’re committed to helping Thamrin Nine maintain optimised performance and set the pace for sustainable urban development in Indonesia.”

These technologies and approaches support Indonesia’s net-zero emissions by 2060 vision, demonstrating how global expertise can address local environmental difficulties at scale.
