As the construction industry accelerates toward Net Zero goals, specifiers are under growing pressure to deliver HVAC solutions that are not only effective and compliant but also environmentally sustainable. In 2025, the spotlight is firmly on technologies that reduce carbon emissions, enhance energy efficiency, and contribute to long-term ESG (Environmental, Social, Governance) goals. For large-scale facilities like warehouses, manufacturing plants, and logistics centres, the challenge lies in striking a balance between comfort, control, and compliance.
Here’s an overview of the key decarbonisation HVAC technologies every specifier should consider this year.
Air rotation heat pumps are revolutionising climate control for large-volume spaces. These systems combine an external heat pump with an internal air rotation unit, delivering both heating and cooling with minimal building penetrations. They address issues like stratification and zoning, making them particularly effective for warehouses and racked environments. To understand more about Air Rotation explore our blog here:
Benefits:
Chiller systems using VRF/VRV technology provide efficient year-round heating and cooling, especially in buildings with varied thermal zones. With heat recovery capabilities and centralised control, they’re well-suited for commercial and industrial environments focused on energy efficiency and precise climate management.
Benefits:
Radiant heating provides direct warmth to people and objects, making it ideal for large or poorly insulated spaces where heating the air is inefficient. It’s a smart choice for zonal or spot heating in warehouses, workshops, and production areas—offering fast comfort with reduced energy waste. Available in electric and gas options, each system is suited to different building sizes and operational needs.
Gas Fired Radiant Heaters
Gas-fired radiant systems are designed for large, open spaces that demand powerful, efficient heat. They’re ideal for high-ceilinged or draft-prone environments, delivering wide coverage and cost-effective operation at scale.
Electric Radiant Heaters
Electric radiant systems are best suited for smaller zones or targeted heating areas where instant, controllable warmth is needed. They offer a clean, silent, and low-maintenance solution—perfect for modern, energy-conscious environments.
These split systems pair outdoor condensers with high-mounted indoor units to deliver heating and cooling efficiently. Ideal for mid-sized commercial and industrial spaces, they offer low-carbon, R32 refrigerant-based performance with precise temperature control and space-saving design.
Benefits:
LTHW systems, especially when paired with Air Source Heat Pumps, offer a sustainable way to heat large buildings at lower water temperatures. They reduce energy use and emissions while providing consistent warmth, though they may require more units due to lower heat outputs.
Benefits:
Warm air heaters remain a versatile and scalable solution for large commercial and industrial spaces, offering rapid heat-up times and broad coverage. While traditionally gas-fired, 2025 brings advanced electric and hydrogen-ready models that align with the shift toward decarbonisation.
Benefits:
Ventilation is essential for maintaining indoor air quality, regulating temperature, and supporting occupant health in large buildings. Mechanical systems offer precise airflow and filtration control, while natural ventilation harnesses passive airflow to reduce energy consumption. When integrated into HVAC design early, both approaches help improve EPC ratings and align with modern building regulations and sustainability standards.

Mechanical Ventilation:
Beyond the core HVAC systems, there are several complementary technologies that can significantly enhance energy efficiency, reduce operational costs, and improve overall building performance. These solutions support smarter, more responsive climate control and are especially valuable in large-scale facilities where small inefficiencies quickly scale into major expenses.
Smart Controls: Enable zoning, scheduling, and remote monitoring for energy optimisation.
Destratification Fans: Prevent warm air from pooling at ceiling height, improving comfort and reducing waste.
Door Curtains: Maintain internal temperatures and prevent external air ingress in busy facilities.
Together, these ancillary components can improve heating performance by up to 30% while enhancing EPC scores and occupant wellbeing.
There is no one-size-fits-all HVAC solution for large-scale buildings. Choosing the right mix depends on building use, internal zoning, insulation, and regulatory targets. Whether it’s radiant heating for spot zones or integrated heat pump and ventilation systems for holistic control, the technologies of 2025 are ready to support your decarbonisation goals.
