ZINEG - THE LOW ENERGY GREENHOUSE: AN INNOVATIVE GREENHOUSE WITH NEW CLIMATE CONTROL STRATEGIES SUPPORTED BY PHYTOMONITORING DATA
Increasing cost and decreasing availability of fossil fuels as well as problems caused be the use of these energy sources resulted in a revision of the energy supply for greenhouses. In a cooperation between several universities and research institutes in Germany (ZINEG) the use of fossil fuels and thereby the emission of (fossil) CO2 is planned to be reduced as much as possible by the use of new greenhouse techniques and strategies in a system orientated approach. In Hannover the Lehr- and Versuchsanstalt Ahlem and the Leibniz Universität Hannover are in cooperation and an experimental greenhouse (960 m2) with maximum thermal insulation, a mainly closed method of operation, using solar energy and integration strategies for potted plants has been constructed. Main targets of this project are the reduction of the carbon dioxide emissions resulting from plant production in greenhouses as well as a reduction of the necessary energy input. One important tool to achieve the aims are energy saving climate control strategies (CCS), such as integration strategies over preferably long periods. These CCS show high unused potential even at little expense. One limiting factor complicating the use of CCS is the limited knowledge of the integration potential of the cultivated plants or plant species. Missing information can be obtained by collecting data concerning the reaction of plants due to a change in climate conditions in the greenhouse. Therefore phytosignals (leaf temperature, net assimilation and transpiration rate) are measured and mathematically calculated online with phytomonitoring systems. These data are being analyzed afterwards. The influence of the climate conditions related to the plant reactions can be examined and used for optimization.
