Advanced Ergonomic Technologies Ltd

Pioneering Underfloor Air Conditioning Since 1993.

AET delivers smarter, more sustainable, and highly adaptable underfloor air conditioning solutions. We’re not just a manufacturer, we’re innovators driving the future of smarter workspaces.

What is Underfloor Air Conditioning?

A smarter way to heat and cool modern spaces.

UfAC uses the raised floor void as a plenum for delivering conditioned air via floor-level Fantile™ units.

Air is drawn back through high or low-level returns, filtered and recirculated for continuous comfort.

It’s flexible, efficient, and designed to adapt to your building.

The flexibility of our underfloor system supports rapid layout changes, minimises disruption during refurbishments, and aligns with modern sustainability and efficiency goals.

Every building has its own set of design challenges, ranging from structural limitations and architectural complexity to specific performance and sustainability requirements.

At AET, we recognise that a one-size-fits-all approach is ineffective in the modern built environment. That’s why our underfloor air conditioning systems are designed with versatility at their core.

We offer a comprehensive range of standardised system configurations that are proven, reliable, and easy to implement. In addition, our engineering team specialises in developing bespoke hybrid solutions tailored to the unique demands of each project.

Whether retrofitting a heritage building, optimising a high-density office, or supporting agile workspaces, we work closely with our clients to ensure the system design aligns with both functional

Maximising space efficiency through smart design.

AET Flexible Space systems offer a smarter approach to HVAC by eliminating the need for traditional ceiling-based services. This design innovation can reduce overall building height by 10–18%, reducing structural volume and associated construction costs. Alternatively, in new builds, this space-saving can be repurposed to add additional floors within the same overall building envelope, potentially increasing usable area and development value without expanding the footprint.

In refurbishment and retrofit projects, removing bulky ceiling services allows for significantly increased floor-to-ceiling heights, creating more open, modern interior environments. This not only improves occupant comfort and aesthetics but also helps to meet or exceed BCO (British Council for Offices) standards, even in buildings with tight spatial or planning constraints.

Whether enhancing spatial efficiency in new developments or unlocking potential in existing structures, AET’s underfloor air conditioning solutions support better building outcomes, functionally, financially, and architecturally.

Designed for ultimate flexibility.

AET Flexible Space systems are engineered to provide exceptional adaptability for modern work environments. Our innovative Fantile™ units operate without the need for hard ducting, allowing them to be easily relocated or reconfigured within minutes. This streamlined design eliminates the complexity and expense typically associated with modifying traditional HVAC systems.

Whether during initial fit-out or post-occupancy, Fantiles™ enable rapid, low-cost adjustments to office layouts, supporting the dynamic needs of evolving businesses. This flexibility not only reduces downtime and disruption but also extends the lifecycle of the building’s mechanical systems by accommodating changes in space usage without major renovations.

By combining ease of reconfiguration with high-performance climate control, AET Flexible Space systems empower organisations to create workspaces that can grow and change with them, maximising operational efficiency and occupant comfort.

At AET, sustainability is engineered into every system we deliver. Our Flexible Space underfloor air conditioning solutions are designed to achieve significant carbon savings without sacrificing comfort, performance, or adaptability.

By eliminating the need for extensive ductwork and overhead services, our systems reduce material usage, streamline transportation, and shorten installation times. This results in an 18% reduction in Upfront Carbon and a 16% reduction in Whole Life Embodied Carbon compared to traditional HVAC systems.

The benefits don’t stop at construction. In operation, our systems deliver ongoing energy efficiency, with up to 52% energy savings for refrigerant-based systems and up to 19% for water-based solutions.

These savings support lower emissions, reduced running costs, and alignment with key environmental standards and certifications.

AET’s Flexible Space systems are future-ready, offering smart climate control that adapts as buildings evolve, all while helping to meet sustainability targets and regulatory demands.

Better for people. Better for buildings. Better for the planet.
