Over the last years you see a lot of new greenhouse models on the market which should enable us to produce sustainable food without using extensively natural resources. In the photos below you see some concept currently tested or in full production in the horticultural produce sector. You have another concept, inform me I am [...]

Elkas (the electricity supplying greenhouse) shows how to convert solar energy into electricity. In designing energy generating greenhouses the emphasis still lies in systems that supply low-grade forms of energy (i.e. warmth). The electricity generating greenhouse is aimed at catching the radiation that is not being used for crop growth and converting it in high grade power.
The inteligent solution for this greenhouse is an integrated filter for rejecting near infrared radiation (NIR) and a solar energy delivery system. Cooled greenhouses are an important issue to cope with the combination of high global radiation and high outdoor temperatures. As a first measure, the spectral selective cover material, which prevents the entrance of NIR radiation, is investigated.
