  • Many concrete results have been achieved since we started the Next generation greenhouse cultivation phenomenon in 2003. What is Next generation greenhouse cultivation, or 'Het nieuwe telen'as it is called in Dutch? In a nutshell, it is more or less taking a different approach to humidity in the glasshouse. Taking a different look at the relationship between the installations and the crop changes the view of the climate. This can lead to savings that are between 25% and 30%!

    "Priva has conducted a great deal of research into and has gained practical experience with The New Horticulture", says Jorrit Budding, Product Manager at Priva. "Our concept, which is based on Next generation greenhouse cultivation techniques, is called the Priva ClimateOptimizer. Where the Next generation greenhouse cultivation concept has seven steps, Priva has gone back to basics."

    The four steps of the Priva ClimateOptimizer concept

    The ClimateOptimizer concept has four steps. These steps deliver the greatest savings while the investments required for this are relatively transparent. All steps can be implemented individually, but the real savings can chiefly be found in a combination of these four steps. The aim of the ClimateOptimizer concept is to achieve considerable energy savings while the production remains the same at least; in many cases the production actually increases.

    The Priva ClimateOptimizer concept consists of the following four steps:

    1. By growing together with nature- using free solar heat - you work using average 24-hour period temperatures where the temperature is kept within a specified bandwidth. Temperature integration saves you around 5% of your energy costs.

    2. Intensive insulation with (additional) energy screens is good for a saving of around 15%.

    3. Using controlled air movement (i.e. a uniform glasshouse climate) reduces the risk of diseases. This improves the quality of your crop. The 5% energy saving that this achieves is the result of air movement using air tubes and fans, which means you will require less use of minimum water temperature.

    4. Reducing humidity using controlled supply of (dry) outside air delivers an energy saving of some 10%.

  • Air movement is an important building block in this concept. Depending on the requirement of your crop you can choose between various types of systems such as vertical fans or air circulation using air tubes.

    energy savings in the horticulture sector

    "At Themato - one of the first semi-closed growers - they achieve higher production with fewer plants per square meter", Budding continues. "The Priva ClimateOptimizer concept is not just a matter of adding a couple of buttons; the growers learn to look at their cultivation in a different way. So, not only at the individual components, but at the entire process. Everything that you do in a glasshouse influences the climate and vice versa."

    Investing in stages

    The Priva ClimateOptimizer concept is eminently suited to staged investments. From small to large, whatever cultivation and investment capacity you have, you can achieve energy savings immediately. Not a bad thing: after all, in horticulture every penny counts.

    In addition to making better use of the available energy, the Priva ClimateOptimizer concept also has a positive influence on suppressing disease. That could result in an increase in production, as well as a saving on crop protection products; the CO2 concentrations can be higher too because the losses from over-controlling the air vents are limited.
