Turn technical infrastructure into living architecture.
CO2Wall transforms technical rooms, HVAC enclosures, pump rooms and utility structures into integrated living environments. By combining climate-resilient vegetation, engineered airflow, precision irrigation and intelligent monitoring, essential infrastructure becomes quieter, cooler and visually aligned with the architecture around it.
MORE THAN A TECHNICAL ENCLOSURE
CO2Wall Technical & HVAC Solutions transform technical rooms, pump stations and HVAC installations into performance-enhancing living infrastructure. The vegetated enclosure helps absorb equipment noise, cool and filter surrounding air and reduce thermal stress — while integrating essential infrastructure naturally into the architecture.
Acoustic performance
The layered CO2Wall structure and dense vegetation help absorb and diffuse noise generated by HVAC units, pumps and technical equipment, creating a quieter environment around the installation without compromising required airflow.
Up to 40% lower energy use
By cooling the environment around the equipment and improving incoming air conditions, CO2Wall can reduce the energy required for operation. When walls and upper surfaces are integrated as one complete living enclosure, energy consumption can be reduced by up to 40%, depending on project configuration and operating conditions.
Lower maintenance · Longer lifetime
Cleaner air and reduced thermal stress help protect components from dust, heat and harsh external conditions. This can contribute to up to 30% lower maintenance costs and up to 60% longer equipment lifetime, depending on the installation and operating environment.
Cleaner air & indoor environment
For HVAC applications, the living surfaces help filter airborne particles and improve conditions around air-intake zones. This can support cleaner supply air and contribute to a healthier, more comfortable indoor environment for the people inside the building.
CO2WALL TECHNICAL & HVAC ENGINEERING
A living enclosure engineered around the equipment inside.
CO2Wall Technical & HVAC Solutions combine structure, vegetation, precision irrigation, engineered airflow and intelligent monitoring in one integrated enclosure. Every system is configured around equipment clearances, air-intake and discharge requirements, service access and local climate conditions — improving the surrounding operating environment without compromising technical performance.
Engineered airflow & cooling
The enclosure is designed around the required airflow of the equipment inside. CO2Wall vegetation helps cool and filter the surrounding air before it reaches intake zones, reducing heat load and supporting more efficient operation. Fully integrated wall-and-roof configurations can contribute to up to 40% lower energy use, depending on project conditions.
Acoustic buffering
Dense vegetation and the layered CO2Wall structure help absorb and diffuse equipment noise from HVAC units, pumps and technical installations, reducing disturbance to surrounding residential, hospitality and public environments.
Service access remains protected
Doors, maintenance zones, ventilation openings and technical clearances are incorporated into the design from the beginning. Individual CO2Wall elements can be accessed or removed where required, allowing maintenance without rebuilding the enclosure.
Protection & longer equipment life
A cooler, cleaner operating environment helps reduce exposure to excessive heat, dust and harsh external conditions. Depending on the installation, this can contribute to up to 30% lower maintenance costs and up to 60% longer equipment lifetime.

SYSTEM CONFIGURATION
ONE PLATFORM · MULTIPLE TECHNICAL ENCLOSURE CONFIGURATIONS
Every CO2Wall Technical & HVAC Solution is configured around the equipment, airflow requirements and environmental conditions of the project. Living wall elements, engineered intake and exhaust paths, precision irrigation, sensing and intelligent control work together as one integrated enclosure system.
Living enclosure integration
The CO2Wall system transforms technical rooms, HVAC compounds and utility enclosures into living architectural elements. The green exterior helps integrate essential infrastructure into landscapes, residential developments and premium public environments.
Engineered intake and exhaust airflow
Each enclosure is designed around the operational airflow needs of the equipment inside. Ambient air is drawn through the enclosure while warm exhaust air is discharged upward, helping prevent recirculation and supporting efficient heat rejection.
Filtered and cooled intake air
CO2Wall vegetation helps filter airborne particles and cool the surrounding air before it reaches intake zones. This can improve operating conditions, reduce thermal stress and support more efficient technical performance.
Accessible service and equipment protection
Doors, service zones and maintenance access remain fully integrated into the enclosure design. At the same time, the living envelope helps shield equipment from heat, UV exposure and harsh external conditions.
IRIXON intelligence
Monitoring, irrigation control, alerts, analytics and software updates keep the green ceiling visible, adaptable and continuously optimised throughout its operational life..
Transforming technical infrastructure into living performance.
TECHNICAL HVAC PERFORMANCE
A living enclosure that improves efficiency, protection and workplace comfort
CO2Wall transforms technical rooms, HVAC enclosures and rooftop service compounds into active living infrastructure. By combining dense vegetation, filtered and cooled intake air, precision irrigation and intelligent monitoring, the system helps reduce energy demand, lower maintenance needs and extend the lifespan of the equipment inside.
Acoustic buffering
CO2Wall cladding helps absorb and dampen installation noise, reducing sound impact on the surrounding environment and creating a quieter, more comfortable setting around technical areas.
Lower energy use
Because intake air is naturally filtered and cooled by the CO2Wall system, HVAC and technical installations can operate more efficiently. When top surfaces are also integrated, energy use can be reduced by up to 40%.
Lower maintenance & longer lifespan
Cleaner operating conditions and reduced heat stress help lower maintenance requirements by up to 30% and can extend the service life of technical equipment by up to 60%.
Healthier building environment
In HVAC applications, cleaner and more oxygen-rich air contributes to a healthier and more productive indoor climate for the people working and living in the building.
Protect the equipment outside. Improve the environment inside.
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 technical integration.
Every CO2Wall Technical & HVAC Solution is engineered around the equipment before installation begins. Dimensions, airflow requirements, service access, planting zones, irrigation and monitoring are coordinated in advance so the living enclosure can be installed efficiently without compromising the operation or accessibility of the technical systems inside.
Pre-engineered configuration
Equipment layout, intake and exhaust zones, maintenance clearances, doors, CO2Wall modules and irrigation routes are coordinated before mobilisation.
Modular installation
The living enclosure is built from modular CO2Wall elements, allowing phased installation and straightforward replacement of individual components where required.
Integration with technical services
CO2Wall is coordinated with HVAC units, pumps, electrical cabinets, pipework, ventilation openings and other technical infrastructure so all systems continue to operate as intended.
Commissioning & handover
After installation, irrigation, sensors, monitoring and system interfaces are tested and commissioned before the complete enclosure is handed over for operation.
Designed around the equipment. Engineered to improve the environment around it.
LONG-TERM OPERATION
Accessible, serviceable and designed to protect performance.
Technical infrastructure must remain accessible throughout its operational life. CO2Wall is therefore engineered so vegetation, irrigation and monitoring can be maintained independently while doors, airflow zones and service areas remain available for inspection and maintenance.
Planned maintenance
Scheduled horticultural and technical inspections maintain healthy vegetation, reliable irrigation and consistent environmental performance.
Unrestricted service access
Doors, maintenance zones and technical clearances remain accessible so HVAC and other equipment can be serviced without dismantling the complete living enclosure.
Replaceable & upgradeable components
Plants, CO2Wall modules, irrigation components, sensors and control equipment can be serviced or replaced individually as requirements or technology evolve.
Remote visibility
IRIXON provides insight into irrigation, sensor data and system status, supporting efficient operation and early identification of abnormalities.
