HORCONEX has developed the Activenlo® greenhouse in accordance with the guidelines of ‘The Next Generation in Greenhouse Cultivation or ‘Het Nieuwe Telen’ programme, a Dutch initiative for stimulating climate-neutral and economically viable greenhouses. This advanced design focuses on ‘active dehumidification’ in the Venlo greenhouse. The primary objective of this concept is to maintain productivity at at least the same level while consuming much less energy. Energy savings of as much as 20% are possible simply by using the Activenlo® greenhouse on its own.
Since the introduction of The Next Generation in Greenhouse Cultivation or "Het Nieuwe Telen" in 2003, a Dutch initiative for stimulating climate-neutral and economically viable greenhouses, many developments have been introduced in the greenhouse horticulture sector. In the past, the greenhouse heating system was turned on in the morning and the windows were opened to activate the plants. While this method is effective, a significant amount of heat is lost through the open windows resulting in (unnecessarily) high energy consumption. The Next Generation in Greenhouse Cultivation has taught us to look at climate control in a different way. More efficient dehumidification of the greenhouse not only significantly reduces costs, it is also an environmentally responsible way of operating your business.
In the case of an Activenlo® greenhouse, a specially developed ventilation system provides active dehumidification. The outer walls of the greenhouse incorporate a chamber which draws in (dry) outside air. The air that is drawn in from the outside is mixed in the chamber with air from the greenhouse to bring it up to the right temperature. Mixing humid air with dry air reduces the amount of energy required to dehumidify the air. Furthermore, the ventilation system in the greenhouse creates a much more homogeneous climate. This also reduces dew formation on the crops and results in less crop disease (e.g. mildew).
The use of additional installation can reduce energy consumption even further. For example, a reduction in energy consumption of as much as 40% can be achieved by insulating the Activenlo® greenhouse more effectively using a double screen. This doubles the savings in the area of energy costs! Performance statistics like these make further investigation on your part worth your while. Based on your input, HORCONEX can calculate the savings potential that an optimum combination has for you.
In addition to saving energy, a more stable greenhouse climate and less crop disease, the Activenlo® greenhouse offers a further major benefit. Investments that you make in innovative energy systems, which reduce CO2 emissions and energy consumption, may qualify for government subsidies. For more information on this subject, please contact us
