Based on the market evaluation, the three
solutions of energy technology selected in
the project will be simulated in the Almería
region (Southeast Mediterranean coast of
Spain) and with regards of two
representative crops (tomato and
cucumber).
Farming system in Almeria, represents the largest concentration of greenhouses in Europe and one of the
key intensive agriculture poles in the world. It performs a case study with water recovery and energy
efficiency in greenhouses.
The Almería case study represents an ideal example of the challenges of the Mediterranean intensive
agriculture, particularly in the important challenge areas of water and energy efficiency. The case study in
Almería will be supported by the network of farmers’ associations that the University of Almería is linked to,
namely, the Association of Exporters and the Irrigation Users Community.
According with the described impact, the studies take into consideration the energy performance and the
related costs as well as the improvement in the productivity and reduction of water consumption, pesticides
and fertilisers.
Energy performance of the three solutions considered in the project for the climatic conditions of Almería will
be analysed using Computational Fluid Dynamics (CFD) simulations. The CFD model provides information of
the effect of different solutions on inside air temperature, humidity, velocity, CO2 concentration and in plant
photosynthesis. Two of the most representative crops cultivated in greenhouses of Almería will be
considered, tomato and cucumber. In the same way, two greenhouse types will be modelled with CFD, roof
pitched Almería-type greenhouses and curved roof multi-spans greenhouses.
An economic analysis of production cost of the application of the different solutions will be carried out based
on the technical-economic data collected through a survey through direct interviews with farmers of
Almería. This analysis takes into consideration all the costs of tomato and cucumber production (inputs
required for crop, labor and investment) and the income of farmers (production and price of sale).
