Estimating the environmental impact of greenhouse vegetable production

Greenhouse gas (GHG) emissions of vegetable production in a greenhouse can be now estimated with Hortinergy.

Hortinergy models the Greenhouse Gas (GHG) Emissions in g CO2/m² or g CO2/kg product.

This will allow growers to estimate greenhouse gas emissions by taking account different parameters:

  • Embodied energy of the greenhouse structure
  • Heating and cooling
  • Liquid CO2
  • Electricity
  • Nutriments
  • Substrate
  • Transport

The above example compares 3 heating techniques for tomato production under a Venlo greenhouse:

  • Gas boiler with CO2 collector in a classic greenhouse,
  • Renewable energy with injection of liquid CO2 in a classic greenhouse,
  • Renewable energy with injection of liquid CO2 in a semi-closed greenhouse.

Energy is the main source of greenhouse gas emissions (GHG). If the greenhouse is heated with renewable energy, the liquid CO2 becomes the most important source. The embodied energy required to manufacture the greenhouse (amortized over the greenhouse life) may be greater than the total amount of other inputs.

Hortinergy offers a simple and fast way to estimate greenhouse gas (GHG) emissions using approved scientific methods, developed by CTIFL.

Design and model your greenhouse with Hortinergy
With the Hortinergy, you can design and model on-line any type of greenhouse all over the world. Hortinergy includes specific parameters of greenhouses:

  • Types of greenhouse, transparent covers, screens
  • Different crops (tomato, cucumber, strawberry, cannabis…) and their evapotranspiration
  • Climate setpoints similar to those of a climate computer (temperature, humidity, light…)
  • Different equipment (semi-closed greenhouse, buffer tank, lighting…)

This decision-making tool lets you:

  • Model the climate inside greenhouses and simulate energy consumption
  • Analyse the results according to your requirements
  • Compare scenarios thanks to an online interface

It can be used for preliminary construction project, renovation or a new cultivation method.
