CO2WALL GREEN CEILINGS
Turn overhead space into living infrastructure.
CO2Wall transforms ceilings, canopies and overhead structures into intelligent living green systems that combine circular engineering, climate-specific planting, precision irrigation and AI-driven monitoring — creating immersive green environments without sacrificing architectural quality.
MORE THAN A GREEN CEILING
A CO2Wall green ceiling transforms an overhead surface into an active part of the indoor environment. Beyond creating a distinctive and luxurious atmosphere, vegetation contributes to acoustic comfort, indoor climate and the way people experience a space — combining architecture, nature and technology in one integrated system.
Immersive atmosphere
Living vegetation creates an unexpected architectural experience, adding depth, exclusivity and a strong natural identity to retail, hospitality, workplaces and public spaces
Acoustic comfort
Vegetation and the layered CO2Wall structure help absorb and diffuse unwanted sound, reducing reverberation while also helping to dampen noise from ducts and technical installations above.
Healthier indoor climate
Plants support a more pleasant indoor environment through evapotranspiration, contributing to natural cooling, humidity balance and improved perceived air quality
Biophilic & commercial value
People are naturally drawn to nature-rich environments. Spaces that feel greener and more comfortable can encourage longer visits, stronger destination appeal and greater value for retail and hospitality environments.
CO2WALL SMART CEILING ENGINEERING
A living ceiling engineered as part of the architecture above it.
CO2Wall Green Ceilings are engineered as modular overhead living systems that integrate structure, planting, precision irrigation and monitoring into one solution. The system can be configured around existing ceiling geometry, technical services and maintenance requirements — allowing nature to become part of the architecture without compromising functionality or accessibility.
Lightweight overhead engineering
The CO2Wall system uses a lightweight modular support structure designed specifically for overhead applications, limiting unnecessary structural load while creating a secure foundation for dense living vegetation.
Controlled overhead irrigation
Integrated precision irrigation delivers water directly to the planting zones in controlled quantities, reducing unnecessary water movement while supporting consistent plant performance across the ceiling.
Technical services remain accessible
The ceiling can be engineered around ventilation ducts, lighting, sensors and other building services, with access zones incorporated where inspection or maintenance is required.
Curves, shapes & transitions
The modular system can follow architectural curves, accommodate roof slopes of up to 60% and transition seamlessly into CO2Wall façade systems.

SYSTEM CONFIGURATION
ONE PLATFORM · MULTIPLE CEILING CONFIGURATIONS
Every CO2Wall Green Ceiling is configured around the architecture, ceiling structure and environmental conditions of the project. Modular planting elements, precision irrigation, sensing and intelligent control work together as one integrated overhead greening system.
Suspended ceiling integration
The CO2Wall system is engineered as a suspended living ceiling solution, integrated into overhead architectural spaces. Depending on the project, the system can be configured around ceiling geometry, technical services and maintenance requirements while preserving a clean architectural appearance
Modular CO2Wall planting elements
Closed modular planting elements form continuous planted rows across the ceiling structure. Their modular construction allows efficient installation, individual replacement and adaptation to straight lines, curves and transitions.
Precision root-zone irrigation
Each planting row is equipped with integrated drip irrigation, delivering water directly into the root zone. Project-specific irrigation lines support efficient water use, stable plant performance and reliable long-term operation.
Sensors & connected devices
Environmental and operational sensors can monitor moisture, temperature, irrigation activity and other project-specific parameters across the ceiling installation.
IRIXON intelligence
Monitoring, irrigation control, alerts, analytics and software updates keep the green ceiling visible, adaptable and continuously optimised throughout its operational life..

GREEN CEILING PERFORMANCE
A living ceiling that enhances comfort, atmosphere and indoor performance
A CO2Wall green ceiling creates an active environmental layer within the built space. By combining vegetation, precision irrigation and integrated overhead engineering, the system contributes to acoustic comfort, natural cooling, perceived air quality and a more distinctive spatial experience.
Acoustic buffering
Vegetation and the layered CO2Wall ceiling structure help absorb and diffuse unwanted sound, reducing reverberation and contributing to a calmer indoor environment.
Natural cooling effect
Through evapotranspiration, vegetation supports a cooler and more pleasant microclimate, helping reduce heat build-up in covered and indoor spaces
Improved indoor experience
A living ceiling enhances the visual identity of a space and creates a more natural, comfortable and memorable environment for visitors, guests and occupants.
Biophilic performance
Nature-rich environments are associated with improved wellbeing, longer dwell time and a more positive perception of the space, adding value to retail, hospitality and public environments

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 ceiling installation.
Every CO2Wall Green Ceiling is prepared project-specifically before installation. Ceiling geometry, module layout, irrigation routing, suspension points and planting plans are coordinated in advance so installation can be carried out efficiently while integrating smoothly with the architectural and technical requirements of the space.
Pre-engineered configuration
System dimensions, module positions, suspension points and irrigation zones are prepared before mobilisation to support an efficient and coordinated installation process.
Modular installation
CO2Wall ceiling elements are installed in organised rows, allowing efficient phased installation and straightforward replacement of individual components where required.
Integration with technical services
The system can be coordinated with lighting, ducts, ceilings and other building services so the living ceiling becomes part of the overall architectural and technical design.
Commissioning & handover
After installation, irrigation, sensors and controls are commissioned and the complete ceiling system is handed over ready for operation

LONG-TERM OPERATION
Accessible, serviceable and designed for decades of use.
Long-term ceiling performance depends on more than healthy planting. CO2Wall is designed so vegetation, irrigation and technical components can be maintained efficiently while preserving the visual quality and performance of the living ceiling over time.
Planned maintenance
Regular horticultural inspections and maintenance help maintain healthy planting, visual coverage and long-term system performance
Accessible technical components
Irrigation lines, sensors and serviceable components can be accessed in a controlled way for inspection, maintenance and adjustment.
