Upgrade & Modernize

Building Systems Upgrades

Technology continues to evolve - as do cyber-security defenses, and IT compatibility requirements, and customers’ productivity expectations.  Trane, as a leading BAS Controls provider, remains current with latest technology trends by innovating to deliver our customers secure, compatible, and feature-rich systems.



Building Systems Upgrades

By the time a typical building is a few years old, its systems are already falling behind. Trane can maintain a high performing building by keeping building automation, HVAC, lighting and central plants up to date with the latest BAS innovations.

Upgrade Your Controls

The old "if it works, don’t fix it" logic went out with the twentieth century. Technology is advancing at lightning speed, presenting new ways to manage systems easier and make buildings better.

Energy Performance

Advanced assessment tools to help you monitor, manage and improve energy consumption—real time—for sustained energy efficiency.

HVAC Modernization

Connected building strategies, next-gen refrigerants, high-efficiency HVAC equipment, and affordable renewable energy and energy storage solutions to support electric load flexibility: it’s all happening today, and it’s how we’re making buildings significantly better.


Switching to newer LEDs? That’s one way to save. We’re also integrating lighting with HVAC controls, diffusing light more effectively—and leveraging the system to collect valuable business data for you.

Central Plant and District Cooling

Advancements in digital analytics and distributed energy resource applications like cogeneration, back up-power, photovoltaic systems and energy storage are helping central plant and district cooling operators to build and grow in a modular fashion, reduce operating costs, enable grid flexibility and be more sustainable.
