Last yr , Lycopersicon esculentum were growing in a test under Geysir glass . This year it ’s aubergines that are being originate in the WUR tryout at Beliswijk . The event so far , combine the Geysir glass with muscularity screens and dehumidification , show a 25 % lower energy consumption compared to a standard Methedrine with energy - saving screens and dehumidification . " raiser always had to choose between high transmittal or more insulation . This glass reach both available " , says Mohammad Shayesteh , director of Agculture , developer of the Geysir methamphetamine hydrochloride .
Geysir is clear ice-cream float glass plow with a depleted - emissivity ( low - E ) coating on the outside of the glasshouse , reflecting far - infrared hotness back into the greenhouse . The glass is then vacuum coated with two AR coatings , protecting the chalk from corroding . " This means we have the high light transmission of humiliated iron glass , combined with better insulations thanks to the low emissivity program , " Mohammad explains , adding that the ice offers growers great potential drop to lower their vigour utilization . " Thanks to the higher insulant , growers can enjoy less cover hr in winter time , when the Light Within is low , which will increase their productivity . The lights can remain off during these times , which will also save on electrical energy consumption . All of this is in favor of growers producing more product in the wintertime time when the prices of produce are high . " Whitewashing the depleted - E coating disables the low emissivity aspect of the glass and warmth retainment procedure , so there is no fear of pin heat in summertime . However , over the last class ’s Lycopersicon esculentum trial at WUR , even without applying a whitewash , the glass did not result in higher inside temperature compare to normal drinking glass . This means that during the summer , raiser can have the same situation as normal shabu , and in winter , sentence can enjoy the extra 25 % vim saving without any shock on craw productiveness .
As Agculture is expect their first order in the fresh future , Mohammad is assured more growers will postdate once the first labor is sign . " In addition to Northern Europe , we also see a slew of interest from Canada and the North of the US , as they have cold winters and comparatively hot summers . A central challenge is the fear of frozen glass due to the very cold temperatures ahead of time in the morning and condensate . One of the proposition for these climates is the glass temperature is always above the dew decimal point . Thanks to the coating on the exterior of the glass chew over the warmth , the heat operate through the glass twice , meaning it ’s always 2 to 3 grade warmer than normal glass type . This causes less inside condensation and avoids outside freezing compass point . And if you are deal with snow , it will melt much faster . "

Tax welfare in Canada and NetherlandsIn the Netherlands , there are also taxation benefit in spot for growers choose for Geysir Methedrine . " to reach the 30 percentage reduced discharge by 2030 , as agreed upon in the Climate plan , many greenhouse need to take action . Re - glazing with our type of glass can aid growers get there . Taking the number of greenhouses into explanation , annually , we would have to re - glaze at least 500 hectare per year . How many of them have done it ? Zero . The industry is far behind these destination and needs to start acting " , enjoin Mohammad . A boost for this in the Netherlands could be the EIA subsidy , which allow for a 45,5 percent of tax reduction of tax income for growers . Canadian growers , on the other hand , might prefer for discount from zip companies . " the support in BC could be up to 75 percent of the task , up to 1 mln computer-aided design . And in addition to their heating benefits , growers will also profit from a lower CO2 emission , and thus less CO2 tax . "
These numbers also appeal to investor , he says , as it matches their sustainability goal . " For investors , function as sustainable as potential is a must because of their finish and obligations , but the horticultural diligence as a whole has to take it into score . It might be a more expensive ware , but the payback time is shorter than anticipate , and the sustainable benefit are more than substantive . We consider this is the mode to go for anyone looking a slight morsel to the mid or long - term . "
