Overview
Our comprehensive HVAC design approach prioritizes comfort, efficiency, building performance, and environmental responsibility, providing all essential system components in one convenient package.
Improved Efficiency
Energy recovery, economizers, and enhanced controls improve efficiency vs traditional VAV. Control sequences match ASHRAE® Guideline 36 (or better).
Environmentally Responsible
Designed to reduce energy consumption, use low-GWP refrigerants, and can be all-electric, eliminating the need for fossil fuels to heat your building.
Simplified Retrofits
Trane Air-Fi® Wireless System, retrofit VAV dampers (RIRO), and pre-packaged controls reduce installation cost, time and inconvenience to building occupants.
Trane® Intelligent VAV Systems combine advanced technology with enhanced controls.
At the core of our system are system control strategies pre-packaged with Tracer™ SC+ system and equipment controllers. Real time dashboards provide essential information about system operation and efficiency.

| Intelligent Variable Air Systems | Building size | Installation or application | Lifecycle Costs | Design Flexibility |
| Chilled-Water Applications | Medium to large buildings | Tied to a central chilled water plant that supplies chilled water to multiple VAV air handlers. | High efficiency solution lowers overall life cycle cost. Additional components needed for hydronic system can increase installation cost. | Greatest flexibility with a variety of energy recovery and other air handler components. |
| Rooftop DX Applications | Small to mid-size | If a central chilled water plant is not feasible, packaged rooftop can be applied to provide the cooling source and air handler for a standalone VAV system. | Trane IntelliPak rooftops meet and exceed regulatory requirements for efficiency. Lower installation cost with packaged system. | Using packaged components can reduce initial costs but may limit design flexibility, making it difficult to meet certain system requirements. |
| Water-Cooled Self Contained Applications | Mid-large office building | Typical installation with a multi-story building. Floor by floor self-contained VAV air handler with a central cooling tower. | Trane’s water cooled, self-contained units meet and exceed efficiency requirements. For high-rise office buildings this offers the lowest install cost solution. | Designed to be compact to reduce footprint. Waterside economizing options enhance efficiency while packaged components limit flexibility. |
Trane Design Assist: We’re making it easy to support your heat pump designs with a free, web-based self-service tool providing comprehensive documentation like overall project layouts, flow diagrams, sequence of operations, points list, and project guide specifications.
Trane TRACE™: Trane has the expertise to help you determine which type of system is right for you. TRACE™ energy modeling program can help compare the two systems based on your institution’s needs.
System Applications
Multiple precision components work together for efficient chilled-water applications for large buildings and DX applications for small- to mid-size buildings.
FAQs
An Intelligent VAV system is a variable air volume system that uses proven products that have been updated to meet the latest efficiency standards and to enhance IAQ, while efficiently managing temperature, ventilation and humidity across different zones within a building.
A typical VAV system consists of a rooftop unit, water-cooled self-contained unit, or an air handling unit that services several individually controlled thermal zones. Each zone has a VAV terminal unit that varies the quantity of conditioned air delivered to maintain a desired zone temperature. System-level controls are used to control the operation of the entire system.
The key difference between VAV and VRF systems is that a VAV uses air and ductwork for temperature control, while VRF uses refrigerant and refrigerant piping for climate management.
