Hanover:
Greenhouse with maximum insulation, closed mode of operation, solar energy use and integration strategies for potted plants.
At the site of Hanover-Ahlem, the focus of the work is set on a greenhouse complex with maximum thermal insulation for the cultivation of potted plants. Other tests involve solar energy use with day-night storage, climate and storage management. The investigation focuses on light and radiation transmittance of greenhouse envelope as well as the energy consumption for energetic evaluation. The horticultural investigations of various potted crops include new approaches to integration and control strategies associated with the determination of the integration and compensation potential of the different cultures.
Systems orientated approach for energiesaving:
1. double glazing 20mm (4/12/4), with Argon, (Groglass) with anti reflex coated glass in the roof and 4-layer acrylic "Steg-Vierfachplatte" in the side-walls
2. tripple thermal screen with different materials: light material (day time thermal screen) material with Al-strips black-out system
3. use of solar energy (day to night storage)
4. energy saving climate control strategies, temperature integration for long time intervalls
5. adapted cropping programs
crop related research with pot plants
1. compensation potential of different crops (temperature integration)
2. influence of energy saving methods on yield and quality of crops
3. phytomonitoring to get a feed-back from the crop (speaking plant approach)
Experimental greenhouses:
2 compartments à 480 m2 + conection greenhouse
