Your path to a smart building

Modernize Your Building With Controls Systems Upgrades

We’ll help you create a plan to upgrade your legacy control systems affordably.

Upgrade Your System
Account Manager Customer Meeting

The world runs on data, and that includes buildings. A modern building control system upgrade boosts energy efficiency, cuts operational costs and ensures ongoing occupant comfort, setting you on the path to achieving a smart building.

Plus, it’s a big step forward in sustainability, helping you tackle decarbonization from all sides. We’ll help you upgrade your existing controls with a migration plan that makes sense for your building, business and budget.


Reasons to Upgrade

  • Higher energy efficiency

    Run your HVAC system as much as you need and no more. Controls support optimal building performance.

  • Enhanced occupant comfort

    Avoid calls from occupants when spaces are too hot or too cold. Building automation can put more control in the hands of those in the building.

  • Increased security

    Cybersecurity requires an always alert mindset. Modern controls are regularly reviewed and updated to protect your building assets.

  • Longer equipment life

    Advanced controls manage equipment operation for the highest efficiency with the lowest operating impact, saving wear and tear on mechanical components.

  • Greater sustainability

    Buildings that know better, do better. Understanding where your energy is being used (or possibly wasted) is the first step in making choices that can reduce your overall carbon impact.


Frequently Asked Questions

Many buildings operate on legacy control systems every day—but doing so can mean compromising on the benefits modern controls can offer.

New controls can help you increase your energy efficiency, boost your team’s productivity and enhance your cybersecurity. They also will allow you to take advantage of data-driven services that can even further amplify the savings you’ll see.

Additionally, finding technicians familiar with older systems is getting tougher, which means support may not be available when you need it most. Plus, newer systems increase cybersecurity and maintain compliance as energy standards become more rigorous.

We can work to phase your controls (and equipment) upgrades to help with a seamless transition. We’ll work with you to evaluate your entire system and then work to sequence your update accordingly.

For example, new HVAC equipment might be incompatible with outdated controls, so installing a new chiller, air handler or other unit could disrupt operations if it doesn’t integrate properly. We’ll offer you solutions like starting with a system-level controller that can reach both your new equipment and your old equipment or leveraging Air-Fi Wireless to tie in old equipment that could have otherwise been stranded.

We can present you with an affordable path to an updated building automation system, helping you avoid the pitfalls of an outdated system while gaining the benefits of a smart building. Your system will be secure and equipped to deliver powerful data insights to drive unmatched energy efficiency and sustainability in your operations.

You don’t have to do everything at once—starting small is an effective path forward. We’ll assess what you have now and recommend improvements that can progressively fund each step toward a smart building. Trane can help identify where you could see significant energy savings—dollars you can allocate toward future improvements. With a plan supported by operational expenses, you could avoid relying on capital expenses to fund your building automation upgrade.

In several ways. Advanced HVAC controls and building automation enhance energy efficiency, helping to reduce a building’s indirect emissions. Symbio® unit controllers enable the electrification of heat, which cuts direct emissions. They also support renewable energy initiatives, such as automating thermal energy storage tanks. Finally, advanced controls improve refrigerant management by detecting and preventing losses and leaks, contributing to environmental protection.
