| Popis: | In the cultivation of amaryllis cut flowers the current energy consumption is around 25 to 30 m³/m² per year. Research into reducing energy consumption using a second energy screen and an energy-efficient climate control strategy was carried out in Bleiswijk, The Netherlands. When the air in the greenhouse became too humid, the vents above the closed screens were opened. If this did not have the required effect the upper energy screen was slightly opened and if this was not enough both energy screens were opened. The normally applied minimum pipe temperature setting was eliminated. Together with growers and a crop advisor the climate and energy consumption were monitored and adjusted if necessary. After correction for differences in weather conditions and heating setpoint 2,6 m³ of natural gas per m2 (13 was saved compared to the energy consumption in the same greenhouse with only one energy screen and standard climate control in the preceding year. No adverse effects on the crop and the shelf life of cut flowers has been noticed. |
