Modern building projects are being asked to deliver more than just comfort. They need to support energy-performance targets, integrate cleanly with building management systems (BMS), meet evolving safety and cybersecurity expectations, and remain maintainable for years after handover.
The pressure is not abstract. The International Energy Agency notes that building operations account for 30% of global final energy consumption and 26% of global energy-related emissions. In Europe, the European Commission said buildings represent around 40% of energy consumed in the EU.
For engineers, consultants, and specifiers, this means HVAC equipment choices are no longer just technical details. They influence operating cost, carbon performance, grid demand, and the ability of a building to prove its performance once it is in operation.
At the same time, project teams are under pressure to reduce complexity. A drive that saves energy but needs extra components, custom integration work, or difficult commissioning can create risk elsewhere in the project. The practical challenge is to specify HVAC drives that improve performance without making design, installation, or lifecycle support harder.
What a modern HVAC drive should help solve
A variable speed drive is often treated as a motor-control component. In a modern HVAC design, it has a broader role. It should help equipment follow actual demand, exchange useful operating data with the BMS, simplify electrical design, and make startup and troubleshooting easier for the people responsible for commissioning and service.
This matters especially for fans and pumps, where small speed reductions can create large energy benefits. Well known fact, that pumps, fans, and compressors in variable-flow applications are particularly suitable for variable speed drives because of their high savings potential, especially where power rises cubically with rotational speed. In simple terms: when the system does not need full flow, slowing the motor can reduce energy use far more effectively than throttling or bypassing flow.
Integration is just as important. Building operators need visibility into alarms, runtime, energy use, and equipment status. Controls engineers need predictable communication with the BMS. Open building protocols matter here because ISO 16484-5 defines the BACnet data communication protocol for building automation and control systems, including equipment used to monitor and control HVAC&R and other building systems. When drives support these protocols natively, project teams can reduce gateways, workarounds, and late-stage integration surprises.
Why HVAC drive selection matters
For projects that need this balance of efficiency, connectivity, and practical engineering support, Schneider Electric’s Altivar™ HVAC Drive family brings together two complementary ranges: ATH200 for compact HVAC equipment and ATH600 for larger or more advanced HVAC applications.
The drives combine functions that often affect cabinet design, wiring, compliance, and integration work:
- EMC filtering
- Motor thermal protection
- Native Modbus and BACnet communication
- Certified safety features
This helps reduce external components, simplify wiring, and create cleaner, more competitive designs. Wall and cabinet mounting options, plus IP20, IP21, and IP55 variants, give designers flexibility when space, environment, or installation method becomes a constraint.
The range also reflects real HVAC operating conditions. The family is designed to operate from -15°C to 60°C and address practical requirements around harmonics, safety, refrigerants, and environmental robustness. With THDi below 48% compliant with IEC 61000-3-12, EMC category C2 or C3, Safe Torque Off certified to SIL3 and Performance Level e, A2L certification, and A3 readiness up to 18.5 kW, the range helps reduce compromises in modern building specifications. ATH200 also includes cybersecurity foundations, while ATH600 adds certified SL1 cybersecurity.
Application flexibility is another design advantage. The family covers fans, pumps, compressors, chillers, heat pumps, air handling units, and cooling towers. ATH600 supports multiple motor technologies, including asynchronous motors, permanent magnet motors, SynRM, and BLDC. That gives designers more room to balance efficiency, acoustics, performance, availability, and system architecture without locking the project into a narrow equipment choice too early.
From energy intent to measurable performance
Energy performance remains one of the strongest reasons to select a variable speed drive. By adapting motor supply to actual load, the Altivar HVAC Drives can deliver system-level energy savings of up to 70%, depending on the application. ATH600 also adds online autotuning to support performance optimization.
Both drives provide access to operating data such as voltage, current, power, energy, speed, torque, operating time, mains voltage, and alarms. This helps move energy efficiency from a design assumption to something that can be monitored, adjusted, and improved during operation. For facility teams, visibility can support better maintenance decisions and faster diagnosis when equipment behavior changes.
Making BMS integration easier
Integration into the BMS is one of the areas where drive selection can either simplify a project or create friction. The Altivar HVAC family includes embedded Modbus and BACnet MS/TP, with BACnet/IP available via communication module. This helps control engineers connect drives into the building’s automation architecture with fewer gateways or custom workarounds.
ATH600 goes further with architecture examples, simulation mode, and dedicated integration support for EcoStruxure™ Building Operation via a smart widget. Offline engineering has also been improved, with automatic visibility of supported objects and easier access to diagnostics and documentation. For project teams, this can mean faster engineering and commissioning. For operators, it can mean better visibility and simpler troubleshooting once the building is live.
Reducing engineering, commissioning, and service risk
Altivar HVAC drives are supported by Schneider tools such as SoMove, Motor Control Configurator, Motor Management Design, Machine Expert HVAC, Automation Device Maintenance, EcoStruxure Building Operation, and Power Monitoring Expert.
For designers, these tools can support selection, configuration, and documentation earlier in the project. Meanwhile, commissioning and service teams can help standardize setup, reduce manual effort, and improve diagnostics and lifecycle support.
ATH600 also brings practical startup and service functions such as macro-based configuration, simplified commissioning menus, duplicated configuration, embedded troubleshooting with time-stamped events, warning descriptions, QR-code access to documentation, and upgrade support.
A drive family that reduces design risk
HVAC drives help solve problems facing modern building projects:
- Reducing energy waste
- Integrating more easily with the BMS
- Supporting demanding site conditions
- Simplifying commissioning
- Giving operators useful data throughout the lifecycle of the building
Seen through that lens, the Altivar HVAC Drive family is more than a product refresh. It gives specifiers and designers a practical way to connect energy performance, open integration, resilience, and lifecycle support in one drive architecture. When those elements are addressed early in the specification, it becomes easier to reduce engineering effort, improve technical performance, and lower lifecycle risk.
