The overall goal of the “Low Energy Greenhouse” joint project (ZINEG) is to reduce the use of fossil fuel-based heating in greenhouse plant production in order to cut CO2 emissions to almost zero. This ambitious goal can only be achieved if horticultural techniques are coupled with technical innovations such as innovative roofing systems, multi-layered thermal screens, closed greenhouse systems, energy-saving climate strategies, specially-adapted cultivation programmes, etc. The focus in Hanover-Ahlem is to develop a greenhouse facility with the greatest heat insulation for the cultivation of potted plants. The utilisation of solar power that is stored day and night as well as climate and storage management is also important. Research is carried out on translucency, the transmissibility of radiation, and energy consumption for the purpose of energy evaluations. The horticultural studies on the cultivation of different kinds of potted plants take a new approach with regard to integration and control strategies associated with the integration and compensation potential of the various crops.

Building design
The greenhouse construction comprises a hot-dip galvanized steel supporting structure with trussed frames complying with DIN 11535/1055. It is a Venlo greenhouse construction and features two different sections and one connecting area. In order to reach the target of growing plants with the lowest possible use of energy, the roof cladding consists of argon-filled insulated glazing with an anti-reflective coating. The side walls feature quadruple skin sheets. A triple thermal screen system made of various materials was installed at the same height of the greenhouse’s eaves. This helps to save energy, protect the potted plants and keeps them shaded if required. Additional technical amenities are, e.g., an assimilation lighting unit, a heat pump, two buffer tanks, trolleys with ebb and flow trays and convector fans to heat the greenhouse facility.
