Year-round automated greenhouses

When a year-round industrial greenhouse is needed

This solution is chosen for a continuous cycle, winter production, contract supplies and the growing of vegetables, herbs, flowers, seedlings and planting material. A winter industrial greenhouse is required when a seasonal structure cannot maintain the set temperature, humidity and light conditions. The production schedule, the number of zones and the available energy resources are taken into account.

What makes a greenhouse a year-round one

Year-round operation is ensured by a coordinated engineering system. Separate systems without a common design calculation will not provide a stable microclimate.

Heating and the thermal circuit

Based on the heat loss calculation, the heat source, the pipework layout, the number of circuits and the distribution of capacity between zones are determined. Turnkey heated greenhouses are equipped with regard to the type of fuel and to redundancy. If a turnkey heated greenhouse is required, the capacity is determined once the input data has been received.

Ventilation, cooling and humidity control

Greenhouses with ventilation are fitted with vents, drives, fans and sensors. Greenhouses with automatic ventilation regulate air exchange according to temperature, humidity, wind and precipitation. Cooling and humidity control are added where necessary.

Supplementary lighting and light regime control

Greenhouses with lighting require a lighting design calculation. It determines the type and placement of the luminaires, the photoperiod and the load on the power supply. The capacity depends on the crop and on the available daylight.

Irrigation, fertigation and drainage

Greenhouses with automatic irrigation are equipped with pumps, filters, tanks and fertiliser dosing units. The composition of the fertigation and drainage systems depends on the crop, the substrate and the growing technology.

Automation and supervisory control

Automated greenhouses combine sensors, controllers and actuators. The climate computer runs scenarios, raises alarms and keeps a log. Greenhouses with intelligent control may include remote monitoring and SCADA, but still require staff involvement.

Levels of automation of a greenhouse complex

Greenhouses with automatic climate control are equipped according to the number of zones and the redundancy requirements.

To select the equipment package, send us the crop, the area, the region and details of the utilities.

How a year-round greenhouse differs from a closed-loop greenhouse

A year-round greenhouse may use ordinary air exchange without full air tightness. Turnkey closed-loop greenhouses belong to a narrower class of 4th and 5th generation solutions with in-depth control of the air environment.

Which structures are suitable for year-round operation

The choice depends on the crop, the area, the climate and the service life. Industrial film greenhouses can operate all year round with a properly calculated thermal circuit. Venlo glass industrial greenhouses are used for large intensive projects. The format is chosen according to the loads, the energy consumption and the requirements of the crop.

What the cost of a year-round heated greenhouse depends on

The budget is calculated once the structure, the heat load, the engineering systems and the installation conditions have been determined.

How energy efficiency and reliability are built in

Losses are reduced by screens, sealing, zoning and sensor-based control. Reliability is increased by backup pumps, power and communication sources, emergency alarms and service access.

What data is required for the calculation

• crop, area, region and operating schedule
• heat source, electrical capacity and water
• growing technology, supplementary lighting and drainage
• number of zones, level of automation and redundancy
• project deadlines
