Transcript of OPTIMISE THE CLIMATE OF YOUR GREENHOUSE PROJECT
Hortinergy – Climate modelling and analysis models and analyses the climate of a
greenhouse anywhere worldwide to quantify and optimise both inputs and climate
This decision-making tool lets you:• Model the climate inside the greenhouses anywhere worldwide
• Analyze the results according to your requirements
• Compare scenarios thanks to an online interface
Really useful for:• preliminary construction project
• renovation
• new cultivation method
Brand new inputs related to climate control and plants:
• Shade and blackout climate screens can be regulated and modelled
• Ventilation, humidification, dehumidification:
- Closed and semi-closed greenhouses
- Pad and fan
- Natural ventilation including insectproof net for vents
• Assimilation light (LED, HPS...)
Main output: climate inside the greenhouse on an hourly basis:
• Temperature
• Relative humidity / Humidity deficit
• Solar radiation and PAR including assimilation lighting
• CO2 concentration
A comprehensive analysis based on hourly climate modelling:
• PAR reaching canopy and assimilation light required to reach DLI (Day Light Integral)
• Horizontal temperature gradient with pad & fan
• Match light/temperature during production cycle
• Estimation of Greenhouse Gas Emitted (g CO2/m²) …

Hortinergy calculates the solar radiation reaching the canopy intothe greenhouse
Ratio temperature to radiation
This ratio indicates the way plants grow and develop. It is the ratio
between daily average temperature and daily solar radiation
