SIOM: Systems integration for international greenhouse horticulture

The Netherlands is the global market leader in greenhouse horticulture. The glass greenhouse with its technical installations has become an important export product. With the use of the System Integration and Optimisation Model (SIOM), the Dutch greenhouse construction industry is gaining a major lead in the world market. 

What makes SIOM unique? 

The SIOM tool has an extensive database with specific components and systems for greenhouse horticulture, such as greenhouse construction, heating, ventilation, cooling and irrigation. Within SIOM you can compare different design variants of the greenhouse with each other. Based on the location, SIOM provides information on local sources such as sunshine hours, precipitation, groundwater and energy. Janssen: "A greenhouse is a combination of many technologies that you can combine to your heart's content. In every place in the world you have to choose a different combination. SIOM provides insight into this and provides valuable information about payback times and operating results and efficiency. These aspects are highly relevant to investors in order to achieve the highest possible return at the lowest possible cost." 

Helping to alleviate food problems 

Food supply is a global issue with major challenges, now and certainly in the future. Clear trends are urbanisation and local-for-local, where people are increasingly producing and consuming food at the source (in this case, the city). "Being able to build suitable greenhouses at any conceivable location will certainly contribute to this. With the help of SIOM it can also be calculated whether it is more efficient and/or more sustainable to grow locally or to opt for food transport," adds Janssen. 

Future dream 

In the coming years SIOM will be further developed and refined in cooperation with Stichting Hortivation. Janssen: "The licensees themselves will take care of filling in and refining the data. Now, for example, there is only standard glass in the database, but soon there will be every conceivable type of glass in the database that can be compared with each other. In the future, users will also be able to use the performance of the built greenhouses to refine the SIOM models, so that future greenhouses will benefit from experiences in a certain area. Because the licensees constantly supplement SIOM with data, the suppliers work together to optimize their sector."
