Powering the HVAC transition: how xylem is enabling the next generation of low-carbon buildings
Europe’s buildings are entering a decisive decade. “The European building sector is undergoing a structural transformation driven by the EU Green Deal” says András Kovács, Senior product manager, Circulators. The revised Energy Performance of Buildings Directive and the Fit for fifty-five package are also accelerating the shift toward climate neutrality, the pressure to electrify heating and modernise HVAC systems has never been greater. Smart controls and low-temperature networks are rapidly becoming the new standard, and the industry is racing to keep up.
Xylem is helping lead this transformation. Through a portfolio built around high efficiency, intelligent control and system-level optimisation, Lowara is enabling installers, consultants and building owners to deliver the next generation of sustainable, electrified buildings.
High-efficiency technology built for modern demands
As energy performance requirements tighten, the need for ultra-efficient pumping solutions is growing fast. Xylem’s ecocirc S, M and L circulators meet this challenge head-on. Their permanent-magnet motors and advanced hydraulic design significantly reduce electricity consumption in residential and light-commercial applications, while Environmental Product Declarations provide transparent lifecycle data to support green building certifications.
For larger commercial buildings, the ecocirc XL range extends this high-efficiency approach. Supported by a Product Sustainability Report aligned with Product Category Rules, it gives consultants and investors the data they need to quantify environmental impact and design systems that meet the demands of modern low-temperature heating.
Intelligent systems that unlock hidden efficiency
As buildings transition to modernised district heating, system performance, not just component performance, becomes the real differentiator. Xylem’s hydrovar® X paired with IE5 ultra-premium-efficiency motors are engineered exactly for this shift.
The combination delivers:
- Maximum motor efficiency at partial load
- Reduced energy losses compared to IE3/IE4 motors
- Adaptive, demand-based pressure and flow control
- Simplified retrofit integration across a wide power and voltage range
This system-level approach improves real-world performance, reduces commissioning time, and shortens payback periods. Instead of incremental gains it unlocks the full efficiency potential of the hydraulic system.
Making energy renovation easier, faster and more accessible
Despite strong policy momentum, building owners still hesitate to modernise. Upfront cost concerns, fragmented legacy systems, a shortage of skilled technicians and complex incentive schemes often slow progress.
Xylem is addressing these barriers through simplification. Retrofit-ready solutions, intuitive commissioning interfaces, and integrated digital controls reduce time on site and minimise risk for installers. Clear Total Cost of Ownership communication and transparent sustainability documentation help decision-makers move forward with confidence.
The principle is simple: the easier it is to modernise, the faster decarbonisation happens.
Proven energy savings that deliver immediate impact
Modernising pumping systems continues to deliver some of the most cost-effective energy savings available in buildings today. Replacing fixed-speed pumps or older IE1/IE2 motors with modern ECM circulators typically reduces pump electricity consumption by 30–60%. When combined with intelligent variable-speed drives and optimised control strategies, additional savings are achieved through improved part-load performance and better hydraulic balancing.
These upgrades also improve reliability, reduce noise, and enable digital monitoring to create long-term operational value beyond energy savings alone.
Digitalisation: the new foundation of HVAC performance
Digital intelligence is now central to HVAC system performance. Modern buildings require systems that can adapt dynamically to load variations and renewable energy inputs. Intelligent controls enable Δp-variable regulation, real-time optimisation, predictive maintenance, and seamless integration with building management systems.
This digital shift extends far beyond traditional buildings. Xylem’s Watering the New Economy whitepaper highlights how the rapid growth of AI and data centres are reshaping global water-energy dynamics. Efficient cooling loops, high-efficiency pumps, and advanced control algorithms are becoming essential to support the digital economy’s expansion; especially in water-stressed regions.
Digitalisation turns theoretical efficiency into measurable performance.
Closing the skills gap through smarter design
Europe’s renovation wave is creating unprecedented demand for skilled HVAC technicians. To support this transition, Xylem is investing in technical training programmes, digital simulation tools, application engineering support, and simplified commissioning interfaces.
By reducing system complexity, Xylem lowers the barrier to correct installation and empowers technicians to deliver high-quality, future-ready systems.
A clear roadmap for 2026 and beyond
Looking ahead, Xylem sees three structural forces shaping the HVAC market: electrification of heating, acceleration of energy renovation and the rapid expansion of AI-driven digital infrastructure. Xylem, Lowara’s strategy is built around efficiency beyond compliance, portfolio simplification, and digital integration as standard. A major milestone was the launch of the hydrovar® X+ Smart Controller in 2026. Designed to unlock hidden system efficiency, it enables adaptive, demand-based operation while dramatically reducing commissioning time. Applicable to high-performance pumping systems without power limitations, it delivers:
- Faster modernisation with lower intervention costs
- Reduced setup complexity
- Improved lifecycle energy performance
Rather than competing on component price, it elevates total system performance.
Supporting the transition to net zero and the digital economy
Cooling applications for data centres are growing rapidly, and the challenge is clear: meet rising demand without increasing freshwater withdrawals. Xylem’s solutions focus on optimising reuse, improving network efficiency, and enabling intelligent control. The path to Net Zero buildings and the growth of the digital economy share the same foundation: resilient and efficient water and energy systems. Xylem’s roadmap supports both, helping the industry move confidently into a low-carbon, digitally connected future.
