After completing the twist of a greenhouse , the constructor might riposte to see how things go or for sustenance or service reasons , but undertaking are rarely monitored soundly unless it ’s at the introduction of an innovation that requires collecting more virtual data . In that case , the builder does monitor the greenhouse closely over a longer period of time . At TNO , effort are being made to develop a way to monitor more greenhouses , referred to as ' Greenhouse Performance Monitoring ' or ' Kas Prestatie Monitoring ' in Dutch . Rick Gitzels worked this out as a trainee at TNO . Two greenhouse constructors have quiz this out already .
For large bridges , amongst others , TNO already keeps supervise the building . In greenhouse horticulture , this is n’t common practice yet . In drill , it ’s the cultivator who keeps track manually . Since more and more greenhouse constituent are connect to the internet , automatonlike removed monitoring becomes potential .
" Sensors and data from nursery are plenty , so that ’s not an issue , " Rick pointed out while he was still a trainee . Currently , he operate in horticulture elsewhere . " We aspire to gain insight in greenhouse performance , for example , by monitoring the homogeneousness of the mood inwardly of the greenhouse , which could indicate whether the vent shut well or not ( topically ) . This is not only interesting for the constructor but also for cultivator , underwriter , and investors . This stands out to us , but even more so to participants of the organisation Stichting Hortivation . This involves an increase telephone number of Dutch glasshouse builder and nowadays also technological party . "
A lot of work?Greenhouse builder that learn TNO ’s plans for the first time were surprised . " They pointed out to us that it takes a lot of work to gather up all that data and create uniformness , that being their reason for not put that effort into all greenhouses , " recalls Egon Janssen , Senior Business Developer at TNO . " However , we point towards the KIS , where greenhouse technology is talk about in a single linguistic process . This makes glasshouse monitoring substantially easy . "
Two greenhouse constructors are currently getting conversant with Kas Prestatie Monitoring , as TNO has devised . One of those constructor is Maurice Kassenbouw . Rick : " By continuing to monitor the greenhouse , they are able-bodied to validate their design and its performance . For example , does the glasshouse heating arrangement run into the initial calculations , or are they showing an excess or performing under capacity ? By comparing various nursery department with the Greenhouse Performance Monitoring , potential defects become visible earlier , as well . For representative , identifying tardiness in installation . The greenhouse builder , in routine , can reapply these learnings in new projects with standardized circumstances . "
Full pictureICT specializer Fer van der Beele is closely involved with the labor at Maurice Kassenbouw . This gloam , the glasshouse constructor had its first experience with a Dutch cucumber agriculturalist equip with the constructor ’s Air & Energy System . Eight sensors were suspended in the glasshouse , in places where the clime was most challenging , according to the grower .
From the beginning of November , the examination continued in the project ' Kas Als Energiebron Hogedraad Komkommer ' ( greenhouse as an vigour rootage high - telegram cucumber ) . " We are very enthusiastic . Our goal is to connect as much technical information as possible to the records of the nursery . That shows the full video , enabling one to better locate possible blemish , for example , in greenhouse climate , and its exact suit . "
Measuring on two layersIn the follow - up test at Botany , it became potential to assess on two layer , a wish from the builder and cucumber agriculturist . " Sensors are place in both the middle of the plant and its head . In half a year , we intend to see the first results . "
The glasshouse at Botany , built by Maurise Kassenbouw , is mark fresh . The in - home developed energy - efficient Air & Energy System is set up , too . The system is also used by various cucumber growers in the south of The Netherlands . " From the moment the system of rules was used , we immediately saw a remainder in the received data . "

First steps takenThe end of the test cultivation is to deal with vigour as efficiently as possible . The Air & Energy System with energy - efficient fans and heat convalescence is excellent for this , says Fer . " That ’s because it maneuver continuously base on momentaneous needs . The system ’s setting are such that the limits of culture can be pushed . "
nursery Performance Monitoring also enables the nursery builder to liken glasshouse . " This path , we are able to see which glasshouse performs well . Currently , we miss these perceptivity . " The greenhouse detergent builder join the labor of TNO too soon .
In the past , the detergent builder took the first steps by himself , propelled by the interest of raiser and the glasshouse detergent builder in monitor the climate data of the Air & Energy greenhouses . " Back then , we worked on our own with sensors to conduct mensuration . At the fourth dimension , this seemed to attend the interest of the grower foremost since he has a actual affinity with the data . Otherwise , it does n’t really come to life , and you do n’t move on . We are convinced that this will be the future . If not now , then tomorrow . "

The amount in the orange plane indicate the number of alert . The amounts in the red planes bespeak the bit of alarms . get across here toenlarge .
Dangers?The question is whether greenhouse builder , in their relationship with the glasshouse owner , are hold back for all those detailed insights on their greenhouse .
Are they not afraid of claim or warrant issues ? Egon flips this around : " On the contrary . It becomes clean where the erroneous belief could rest . Is this the construction ? Or is it cause by the grower ’s behavior ? Or perhaps the circumstances ? Greenhouse Performance Monitoring allows you to explicate things , trace them and see from them . " Fer knows that Maurice Kassenbouw has considered the aforementioned risks . " We build eminent - quality greenhouses but go on to look for likely additions and betterment . To do so , you need to dare to measure out and gain newfangled insights . "
Egon also flips ' the peril ' of possible opposing interests between the nursery builder and proprietor around when we present him with the example of an inhomogeneous greenhouse climate . " The temperature remainder can have many causes : poor designs , faulty installations , but also faulty setting or poor maintenance is possible . nursery Performance Monitoring permit distant and faster insights into the origins of malfunctions . If the homogeneity of the greenhouse clime declines , you could cross out causes by looking at the data . There is n’t data on everything , such as a broken window , but retain an eye on the data takes you quite far already . Furthermore , the implementation of contrived intelligence help . Comparing situations is possible at a faster speed , as well as determining correlations , which allows for indications of issues such as a malfunctioning fan or warming tube . "
OptimizingMaurice Kassenbouw has already sold sensors to client and is consider how the new insights and measuring can be placed on the market commercially . Another choice is lease sensor , say Fer . " The sensors will be placed in the grower ’s glasshouse for a sure menstruum . The grower can even still buy the sensors later on . A letting reduces the investment funds and alleviate ingress . "
Independent of the eventual shape , the builder wants to optimise together with the cultivator . " Even if we localize a second nursery next to the late greenhouse of the grower , they will never be one hundred pct alike . Especially the first year agriculturalist are singular about how they can cultivate best in their young greenhouse . With sensors and the insights derived from them , we can find answers to this doubt in tandem with the grower . The goal is to eventually finetune everything . "
The end goal of Greenhouse Performance Monitoring is to optimise both the design and the performance of the greenhouses . " More and more greenhouses are outfit with sensing element as such that makes Greenhouse Performance Monitoring possible , even in nursery at a peachy distance from The Netherlands , " concludes Rick .
Personal dashboardAdditionally , Fer emphasizes the grandness of the KIS . " Within KIS , it is wanton to connect data point from various party . When lots of technical political party do this , this generates a much more complete moving-picture show of the technical instalment . This was reinforced by the grower that we worked with . He believed there are still too many islands with data point . "
Fer , an ICT world himself , is n’t afraid of ending up with too much data in a single dashboard . " you’re able to easily structure your personal fascia to your own preference so that all relevant data becomes seeable to you at a coup d’oeil . what is more , you’re able to specify in with child point for which misplay you would wish a notice . The results are incontrovertible and surprising and pave the way of life for a better clime , cultivation scheme , energy policies , horticultural glasshouse , and accessory . "
