The Three Innovations of the 3-Climates Greenhouse


3-Climates Thermofoil

Our thermoreflective coating helps ETFE foils block up to 45% of infrared (IR) rays significantly reducing heat absorption, while still allowing 85% of UV light to penetrate - enhancing photosynthesis.

Thermodynamic Architecture

Our three-layered ETFE design is designed to filter 78% of IR rays from reaching the plants. With a drivable system ensuring both energy and light efficiency, the thermoresponsive architecture keeps plants continuously in an optimal microclimate — ensuring maximum crop yields.

Smart Control

Developed in collaboration with the Fraunhofer Institute, our Smart Control System utilizes a real-time 3D twin to continuously monitor and adjust greenhouse conditions proactively.

THE BREAKTHROUGH OF THERMOREFLECTIVE 3-CLIMATES ETFE FOIL

At the heart of our greenhouse technology is our proprietary ETFE foil, enhanced with an advanced thermoreflective coating - developed in collaboration with the Center for Applied Energy Research (CAE), Germany.  This specialized coating represents years of applied research and engineering refinement. 

Our 3-Climates ETFE Foil blocks up to 45 % of infrared (IR) radiation, whereas conventional ETFE can only block around 6%. 

At the same time, it achieves 91 % light transmission, outperforming glass while still filtering unwanted infrared heat and preserving the full photosynthetic spectrum. 

Unlike conventional polyethylene (PE) films — which degrade under UV exposure and require replacement every 1 to 5 years — our coated ETFE foil delivers an exceptional lifespan of over 20 years, ensuring long-term performance, optical clarity, and sustainability.

 
 

 

 

3 CLIMATES DESIGN
AND SMART CONTROL

Our 3-Climates ETFE Foil is engineered with a three-layer thermal architecture that automatically creates and balances three independent climate zones within the greenhouse.
It reflects up to 78 % of incoming heat, maintaining ideal growing conditions
while lowering cooling energy demand.

  • TOP LAYER
    89% of the full light spectrum penetrates the greenhouse, with only 55% of IR radiation passing through.
  • MIDDLE LAYER
    The 3-C Foil reflects IR rays once again, reinforcing the effect of the top layer. This keeps the greenhouse cool while allowing photosynthetically active radiation (PAR) to pass through, enhancing photosynthesis.
  • BOTTOM LAYER
    During peak sun exposure, this layer activates as additional insulation, blocking over 78% of IR rays, allowing only 22% to pass through, while still permitting PAR to promote plant growth. This also helps protect leaf temperature and healthy growth.

SMART CONTROL SYSTEM

Advanced sensors continuously monitor environmental parameters such as temperature, light intensity, and humidity. The system utilizes the digital twin to analyze this data in real-time, enabling automatic adjustments to each ETFE layer proactively. This ensures that optimal conditions are maintained before any adverse changes occur, maximizing energy efficiency, enhancing crop yields, and promoting sustainable agricultural practices.

Superior Light Transmission
Flavour That Stands Out

Our thermoreflective 3-Climates ETFE foil features exceptional UV light transmission that enhances photosynthesis efficiency. This increased photosynthetic activity leads to higher sugar levels in plants, producing fruits and vegetables with richer, more natural flavors—comparable to those grown under open sunlight. By precisely balancing cooling performance with optimal light diffusion, our system maintains ideal climate conditions while ensuring plants receive the full spectrum needed for healthy growth. The result is a premium harvest that meets the highest standards of flavor, nutrition, and quality.

WHY IS THIS A REVOLUTION?

The Three Climates House is not only designed for extreme wheater Conditions in the desert. It is designed for the ever more increasing extreme wheater conditions all around the world. Opting for the Three Climates House ensures significant economic savings through enhanced energy efficiency and increased crop yields, maximizing your return on investment. Here are some additional benefits and advantages:

  • light-optimised and energy-efficient
  • durable and self-cleaning thanks to the lotus effect
  • shorter cultivation times thanks to better use of sunlight and minimisation of pesticides
  • Energy optimisation through coatings that reflect heat radiation without causing significant light loss
  • Outdoor conditions in the light spectrum of up to 94%
  • Healthy growth and optimised flavour

The Six Innovations of the Solagrow Greenhouse


Movable Bifacial PV Modules

Dual-sided solar panels track the sun, generating energy while shading the crops. In summer they close for maximum power, in cooler periods they open wider — balancing light and energy all year.

Thermoreflective ETFE Foil

Our thermoreflective ETFE foil reflects up to 45 % of infrared heat while allowing UV light to pass through — promoting faster growth, richer flavor, and healthier plants.

Solar-Powered Cooling

Excess heat is managed by high-efficiency cooling systems powered by the PV modules, maintaining an ideal microclimate even above 45 °C.


CO₂ Enrichment

A controlled CO₂ injection boosts photosynthesis, compensating for the shading of the panels and increasing both yield and crop quality.

AI-Driven Smart Control

An AI-based control system monitors light, temperature, humidity, and CO₂ in real time. It predicts changes early and adjusts the climate automatically — ensuring perfect balance with zero human error

Closed-Loop Water Recovery

Condensation and drainage water are collected, filtered, and reused — reducing freshwater use by up to 60 % and ensuring full resource efficiency.

 
 

 

 

SOLAGROW DESIGN
AND MOVABLE PV CONTROL

Our SOLAGROW system ombines movable bifacial PV modules with a thermoreflective ETFE roof to balance sunlight, shade, and energy production in real time. The panels track the sun, generating clean electricity for cooling and automation while ensuring optimal light for plant growth — creating a perfectly balanced climate, even under extreme conditions.

  • SUN MODE
    When solar radiation peaks, the PV modules tilt to create shade and harvest maximum energy. This reduces heat inside the greenhouse and powers all cooling systems directly from the sun.
  • CLOUD MODE
    On cloudy or cooler days, the panels open wider to allow more light to reach the plants — ensuring continuous growth and photosynthesis, even with reduced sunlight.
  • BALANCE MODE
    Throughout the day, AI-driven control continuously adjusts each module’s position to maintain the ideal balance between energy production and plant illumination. The result: energy self-sufficiency, stable temperatures, and a consistent light environment for year-round cultivation.
