CO2WALL INTELLI TUNNEL
Adaptive Light · AI Traffic Awareness · Autonomous Cleaning · Circular Water
CO2Wall Intelli Tunnel transforms tunnels, underpasses and underground mobility spaces into intelligent living environments. Dynamic daylight, sensor-driven traffic awareness, AI-controlled cleaning, precision irrigation and circular water management work together through Irixon — creating a safer, quieter and more natural mobility experience
MORE THAN A TUNNEL
Intelli Tunnel transforms conventional underground infrastructure into an adaptive living environment. By integrating dynamic daylight, intelligent sensing, AI-driven operations and CO2Wall living surfaces, the tunnel continuously responds to traffic, people and environmental conditions — creating a more natural, efficient and intelligent mobility experience.
Adaptive daylight
Intelligent lighting continuously follows outdoor light conditions, including intensity and colour temperature. This creates a smoother visual transition between outside and underground environments and reduces the abrupt change between daylight and conventional tunnel lighting.
Intelligent traffic awareness
Integrated sensors detect the presence and movement of vehicles and people while AI analyses traffic intensity and usage patterns. Information can be shared with the traffic control centre or used by Irixon to initiate predefined actions automatically.
Autonomous operations
Irixon connects lighting, irrigation, cleaning, sensors and optional lane or emergency management within one intelligent ecosystem. AI can determine the right moment for maintenance or cleaning and automatically pause operations when approaching traffic or people are detected.
Living & circular infrastructure
CO2Wall living surfaces provide acoustic absorption, environmental filtration and a powerful biophilic experience. Run-off and cleaning water can be collected, filtered and reused, turning conventional tunnel infrastructure into a more circular and resource-efficient system..
CO2WALL INTELLI TUNNEL ENGINEERING
One intelligent ecosystem engineered around the tunnel.
Intelli Tunnel integrates living CO2Wall surfaces, adaptive lighting, sensors, irrigation, cleaning, water management and traffic intelligence into one connected infrastructure system. Controlled through Irixon, every component can respond dynamically to traffic, people and environmental conditions — transforming conventional underground infrastructure into an adaptive, self-managing environment
Adaptive daylight engineering
Dynamic lighting continuously responds to outdoor light conditions, adjusting intensity and colour temperature throughout the day. This creates a more natural transition between daylight and the underground environment while allowing lighting to respond intelligently to actual tunnel use.
Integrated sensing & traffic intelligence
A distributed sensor network detects vehicles, people, movement and traffic intensity throughout the tunnel. Irixon combines this information into one real-time operational layer that can support traffic control centres or automatically activate predefined responses.
Autonomous cleaning & maintenance
AI can determine suitable cleaning periods based on tunnel activity and operating conditions. If a vehicle or person approaches an active cleaning zone, the process can automatically pause and safely resume once the area is clear.
Circular water & living infrastructure
Precision irrigation supports the living CO2Wall surfaces while collected run-off and cleaning water can be filtered and reused within the system. Water, vegetation and technical infrastructure therefore operate as part of one increasingly circular ecosystem.
Turn underground infrastructure into an intelligent living ecosystem.
SYSTEM CONFIGURATION

ONE PLATFORM · MULTIPLE INTELLIGENT TUNNEL FUNCTIONS
Every CO2Wall Intelli Tunnel is configured around the tunnel architecture, traffic profile and operational requirements of the project. Living wall elements, adaptive daylight, precision irrigation, sensing, AI-driven cleaning and intelligent control work together as one integrated underground infrastructure system.
Adaptive daylight ceiling
The Intelli Tunnel ceiling is designed to bring calibrated artificial daylight into the underground environment. Light intensity and colour temperature can continuously align with outdoor conditions, helping create a smoother visual transition between outside and inside.
Living CO2Wall tunnel walls
CO2Wall living wall zones transform tunnel and underpass interiors into greener, more pleasant environments. The planted surfaces contribute to acoustic absorption, air filtering and a more natural user experience throughout the tunnel.
Precision root-zone irrigation
Each planted zone is equipped with integrated drip irrigation, delivering water directly to the root area in controlled quantities. This ensures efficient water use, stable plant performance and reliable long-term operation in demanding underground environments.
Sensors & traffic awareness
Integrated sensors can detect vehicles, pedestrians, movement, operational activity and environmental conditions throughout the tunnel. This data supports real-time monitoring and enables responsive actions by the control platform or traffic management systems.
Autonomous cleaning & maintenance
The Intelli Tunnel system can include AI-managed cleaning of the tunnel walls and operational zones. Cleaning can be scheduled automatically at the right moment and can pause immediately when approaching traffic or people are detected.

The adaptive daylight ceiling helps create a brighter and more natural underground atmosphere. By aligning light intensity and colour temperature with outdoor conditions, the transition between outside and inside becomes smoother and more pleasant.
Improved air & environmental quality
CO2Wall living surfaces contribute to a healthier perceived environment by supporting air filtration, biophilic quality and a more comfortable underground experience for drivers and passengers.
Premium underground experience
The combination of greenery, natural-looking materials, intelligent lighting and integrated technology transforms the parking garage from a purely technical space into a high-quality architectural environment that adds value to the overall property experience.

A premium parking experience shaped by nature, light and intelligence.

PLANT STRATEGY
Planting designed for climate, performance and identity.
CO2Wall planting strategies are never generic.
Each project is developed around climate conditions, solar exposure, irrigation behaviour, maintenance requirements and the architectural ambition of the location.
INTRO SECTION
Planting is part of the system, not added afterwards.
At CO2Wall, planting is engineered as part of the total living-infrastructure solution. Species selection, visual composition, growth behaviour and water demand are aligned with the system design from the beginning, helping every façade perform as well as it looks.
Climate-specific selection
Plant palettes are adapted to local climate conditions, sun exposure, orientation and environmental stress factors.
Performance-based design
Planting is selected not only for appearance, but also for coverage, durability, cooling effect and long-term stability.
Visual composition
Patterns, textures, tones and species mix are designed to support the architectural identity of the project.
Operational suitability
Growth rate, maintenance behaviour, replacement strategy and irrigation compatibility are considered from the start.
PLANT STRATEGY IN PRACTICE
From species selection to living composition.
CO2Wall translates project requirements into structured planting strategies that combine performance, biodiversity and visual quality. Depending on the project, planting can be calm and uniform, dynamic and expressive, or shaped into a recognisable visual identity.
Coverage & density
Planting strategies are developed to create the desired visual density while preserving healthy growth conditions.
Colour & texture
Leaf size, tone variation and textural contrast are used to give each installation its own character.
Growth behaviour
Species are selected for how they establish, mature and respond over time in the intended conditions.
Project identity
Planting can support a restrained architectural appearance or become a defining visual feature of the location.
Every plant has a role. Together they form one living system.
DIGITAL PLANT DESIGN

Designed with precision before installation begins.
CO2Wall uses its dedicated plant-design platform to define exactly where each plant species is positioned within the living wall — whether the project covers 1 m² or 100,000 m². This gives full control over patterning, plant distribution, quantities and execution quality before installation starts.
Exact species positioning
Every section can be mapped in detail, ensuring the right plant is placed in the right location.
Scalable planning
The same design logic can be applied consistently across small features, large façades and full portfolios.
Execution certainty
Planting plans support production, logistics, installation and replacement with greater precision.
Visual control
Design intent, density, colour balance and patterning can be tested and refined before delivery.
From concept to exact plant position, digitally planned, physically realised.
BIODIVERSITY & RESILIENCE
Planting should support more than appearance alone.
A well-designed living wall can contribute to healthier urban ecosystems by creating habitat, introducing vegetative diversity and supporting climate resilience. CO2Wall planting strategies aim to balance architectural quality with ecological value.
Flora diversity
Mixed species strategies can create richer and more resilient living surfaces.
Fauna support
Planting can help provide shelter and ecological value for insects and urban biodiversity.
Adaptability
Species mixes can be adjusted to local environmental conditions and project priorities.
Long-term resilience
A diverse and well-considered planting strategy supports durability over time.
The best planting strategy is never only beautiful. It is beautiful because it is engineered to thrive.
INSTALLATION & DELIVERY
Engineered for efficient tunnel integration.
Every Intelli Tunnel is engineered project-specifically before installation. Tunnel geometry, CO2Wall zones, adaptive lighting, irrigation, sensors, cleaning systems and technical interfaces are coordinated in advance so installation can be carried out efficiently while minimising disruption to tunnel operations.
Pre-engineered configuration
System dimensions, module positions, lighting zones, sensor locations, irrigation routing and control architecture are prepared before mobilisation, allowing the complete ecosystem to arrive on site as a coordinated solution.
Modular installation
CO2Wall elements and technical components are installed in modular sections. This supports phased installation, efficient replacement and project-specific installation strategies for both new-build and existing tunnel infrastructure.
Integration with technical services
Intelli Tunnel can be coordinated with lighting, ventilation, traffic management, emergency systems, cameras, signage and other tunnel infrastructure so that living and technical systems operate as one integrated environment.
Commissioning & handover
After installation, irrigation, adaptive lighting, sensors, cleaning functions and Irixon controls are tested and commissioned. The complete system is then handed over ready for monitored operation.
Designed overhead. Installed to transform the space below.
LONG-TERM OPERATION
Accessible, serviceable and designed for decades of operation.
Long-term Intelli Tunnel performance depends on more than healthy vegetation. CO2Wall is designed so planting, irrigation, lighting, sensors and intelligent control systems remain accessible, maintainable and upgradeable throughout the operational life of the tunnel.
Planned maintenance
Plant health, irrigation, lighting and technical systems can be inspected and maintained through planned service cycles designed around tunnel usage and operational requirements.
Accessible technical components
Irrigation lines, sensors, lighting components and serviceable system elements remain accessible for inspection, adjustment and maintenance without dismantling the complete installation.
