Smart greenhouses are built to achieve one primary goal:maximum crop performance with minimum resource input. While sensors, software, and automation platforms often receive the most attention, the effectiveness of a smart greenhouse ultimately depends on how well it can physically manage heat, light, and humidity.
This is where climate screens become indispensable.
Climate screens are not just accessories or optional upgrades. In modern commercial greenhouses, they are fundamental climate-regulating tools that allow smart control systems to function effectively. Without climate screens, even the most advanced control software struggles to prevent heat loss, overheating, and climate instability.
This article provides a comprehensive explanation of how climate screens work in smart greenhouses, the different types available, how they are controlled, and why they are among the most cost-effective investments for improving energy efficiency, crop quality, and return on investment (ROI).
Climate screens are movable textile installed inside the greenhouse, usually beneath the roof structure. They can be opened, closed, or positioned partially to regulate the internal environment.
Unlike fixed shading materials or manual curtains, climate screens in smart greenhouses are:
Automatically controlled
Continuously adjustable
Integrated with climate control software
Their main functions include:
Reducing heat loss
Controlling solar radiation
Improving climate uniformity
Supporting humidity management
Enhancing energy efficiency
In a smart greenhouse, climate screens respond dynamically to sensor data rather than fixed schedules or manual decisions.
In smart greenhouses, climate screens serve as the physical execution layer of the control system.
While sensors and software determine what needs to happen, climate screens are the tools that make those decisions effective by directly influencing the greenhouse environment.
They work in close coordination with:
Heating systems
Ventilation systems
Cooling systems
CO₂ enrichment systems
This coordination allows the greenhouse to maintain optimal growing conditions while minimizing energy use and operational costs.
Thermal screens are designed primarily to reduce heat loss, especially during night-time and cold periods.
High insulation performance
Often aluminized or reflective
Installed horizontally or as retractable layers
Automatically close at night
Reduce heat loss through the roof
Lower heating demand
Thermal screens can reduce night-time heat loss by 20–50%, making them one of the fastest payback components in a greenhouse project.
Shading screens control solar radiation intensity entering the greenhouse.
Available in different shading percentages
Transparent, semi-transparent, or reflective
Designed for daytime operation
Prevent overheating during peak radiation
Reduce cooling and ventilation demand
Protect crops from light stress
Automated shading ensures crops receive sufficient light without excessive heat accumulation.
Many modern climate screens combine energy-saving and shading functions.
These screens:
Provide insulation at night
Control radiation during the day
Reduce the need for multiple screen layers
They are particularly useful in regions with large day–night temperature differences.
Diffuse screens scatter incoming sunlight, improving light distribution within the crop canopy.
Benefits include:
Reduced hot spots
More uniform light penetration
Improved photosynthesis efficiency
Diffuse screens support both energy efficiency and crop quality by minimizing localized overheating.
Climate screens are controlled using real-time data from multiple sensors, including:
Indoor temperature sensors
Outdoor temperature sensors
Solar radiation sensors
Humidity sensors
Wind and rain sensors
Instead of simply opening or closing, screens often operate at partial positions, allowing precise climate adjustment.
In smart greenhouses, climate screens never operate alone. They are synchronized with other systems to avoid conflicting actions.
Examples include:
Closing thermal screens while reducing heating output
Partially opening screens to allow ventilation without heat loss
Combining shading with natural ventilation to reduce cooling energy
This integrated approach is key to achieving maximum energy efficiency.
Heat loss through the greenhouse roof represents one of the largest energy losses.
Thermal climate screens:
Create an insulating air layer
Reduce upward heat movement
Stabilize night temperatures
As a result, heating systems operate less frequently and more efficiently.
Shading screens reduce the amount of solar heat entering the greenhouse during hot periods.
This leads to:
Lower internal temperatures
Reduced need for forced cooling
More effective use of natural ventilation
Cooling energy savings are especially important in warm and high-radiation climates.
Frequent temperature fluctuations increase energy use and stress crops.
Climate screens:
Smooth temperature changes
Reduce extreme peaks and drops
Maintain more uniform growing conditions
Stable climates reduce emergency heating and cooling events, improving overall efficiency.
Humidity control is a critical challenge in energy-efficient greenhouses.
High humidity increases disease risk, but traditional solutions often rely on excessive ventilation, which wastes heat.
Smart climate screen strategies allow:
Controlled air circulation
Reduced condensation
Efficient dehumidification
By retaining warm air while managing moisture, climate screens support both plant health and energy efficiency.
Glass greenhouses offer excellent light transmission but also experience high heat loss.
Climate screens are essential because they:
Reduce energy consumption by 30–45%
Improve night insulation
Stabilize temperature distribution
Most commercial Venlo greenhouses use two or more screen layers for optimal performance.
Polycarbonate structures provide better inherent insulation.
When combined with climate screens:
Heating costs are reduced by 25–40%
Climate uniformity improves
Energy efficiency increases significantly
Although plastic film greenhouses have lower baseline energy use, climate screens still provide major benefits.
They:
Reduce night-time heat loss
Control overheating during sunny days
Extend the growing season
Energy savings of 15–30% are common with proper automation.
Climate screens influence not only energy use but also crop growth and quality.
Benefits include:
Reduced plant stress
Improved light uniformity
More consistent temperatures
Higher yield stability
For high-value crops such as tomatoes, cucumbers, berries, and flowers, even small improvements in climate control lead to measurable economic gains.
Thermal screens fully closed
Heating output optimized
Stable minimum temperatures maintained
Shading screens adjusted dynamically
Partial opening for light balance
Coordination with ventilation
Gradual screen movement at sunrise and sunset
Avoidance of sudden climate shifts
Improved crop comfort
Climate screens are often among the highest-ROI investments in greenhouse automation.
Typical results include:
Energy savings of 20–50%
Payback periods of 1–3 years
Improved yield consistency and quality
In many projects, climate screens alone justify the investment in smart greenhouse control systems.
Manual or poorly automated operation
Incorrect screen material selection
Insufficient sensor coverage
Poor commissioning and calibration
Ignoring crop-specific climate needs
Proper design, installation, and control strategy are critical to achieving expected results.
Energy-efficient climate screen systems help:
Reduce greenhouse gas emissions
Meet sustainability standards
Qualify for green financing or subsidies
Sustainability and profitability increasingly go hand in hand in modern greenhouse projects.
Climate screens are particularly valuable when:
Energy costs are high
Climate conditions are extreme
Crops are sensitive to temperature and light
Year-round production is required
For most commercial smart greenhouses, climate screens are no longer optional—they are essential infrastructure.
Climate screens are a cornerstone of smart greenhouse design. By enabling precise control of heat, light, and humidity, they significantly reduce energy consumption, improve climate stability, and enhance crop performance.
When fully integrated with smart control systems, climate screens transform greenhouse management from reactive operation to predictive, energy-optimized production.
