Vincent van der Lans:
"A cubic meter of gas saved, is a cubic meter earned”"
"In our company in Rilland, we’re currently conducting research on the Next Generation Semi-closed greenhouse. We have set aside and adjusted a department of 4,000 m2. This department is equipped with an air conditioning system allowing the greenhouse to be dehumidified with windows closed. There are two trunks installed per frame and outside of we have a facility for the system and a heat pump. The ventilation capacity is 10m3 / (m2. hour) and the cooling capacity is 40 Watt/m2.
We planted in the first week of December and we’ve been harvesting for about three weeks now. So far, I don’t see any real difference in crop or yield. But it’s too soon to tell. We don’t have the numbers yet.
Feije de Zwart of Wageningen UR Greenhouse Horticulture monitors the cultivation and the energy consumption and gives advice where necessary. Cultivation in the Next Generation Semi-closed greenhouse is then compared to the other departments in the company. In the course of the year we hope to have some solid conclusions.
The goal of the Next Generation Semi-closed greenhouse is to save up to 10 cubic meters of gas compared to the standard cultivation. That might be a bit ambitious, so I’m curious where this is heading. But I would say that a cubic meter of gas saved, is a cubic meter earned.”
