Supporting Engineers who are designing the future. 

Trane Commercial Building Systems

Pre-engineered for efficient and cost-effective electrified solutions

Comprehensive Chilled Water Systems

Comprehensive chilled-water systems employ best practices in chiller plant design that align with current industry guidance for achieving high performance cooling, heating, and ventilation, all while reducing first cost.

Comprehensive Chiller-Heater Systems

Trane® Comprehensive Chiller-Heater systems, featuring electric heat pumps, provide cost-effective, energy-efficient, reliable cooling and heating, while reducing carbon emissions. We offer multiple options and variations, so that more buildings in more places can maintain year-round comfort while working to reach their decarbonization goals.

CoolSense® Integrated Outdoor Air Systems

The CoolSense® pre-packaged HVAC design system combines a dedicated outdoor-air system (DOAS) with chilled-water sensible-cooling terminal units to deliver a flexible, energy-efficient solution that enhances comfortable spaces and simplifies maintenance.

Intelligent VAV Systems

Trane Intelligent VAV systems simplify the design and implementation of systems that HVAC designers typically consider complicated and time-consuming. With new technologies and optimized controls, these systems are 20% to 30% more efficient than traditional multiple-zone VAV systems.

Thermal Battery Systems

Trane Thermal Battery™ systems are premier HVAC plants that provide a distributed resource for our changing grid. Their ability to store thermal energy enables your building to reliably modify HVAC operations to optimize for carbon reduction or energy cost savings.

Variable Refrigerant Flow (VRF) Systems

Regardless of the capacity, energy efficiency, functionality or performance-monitoring requirements, our VRF Systems Solutions, featuring Trane® / Mitsubishi Electric VRF Technology, are designed to exceed the comfort and sustainability goals established for commercial building projects.

Zoned Rooftop Systems

Ideal for small buildings, Trane® Zoned Rooftop Systems provide cost-effective options to increase comfort and energy efficiency, while simplifying operation and maintenance. These packaged systems make advanced functionality affordable and easy for non-technical users to operate.
