Modern energy-efficient greenhouses are built on a large scale with glass with anti-reflection treatments to get more sunlight into the greenhouse and thus more solar energy to save fossil fuels and more sunlight for more production. Uncertainty in how a new greenhouse will perform in the next 10 years after construction will lead to reluctance to invest in energy-saving measures and innovation in general. By removing this uncertainty, the sector will be able to invest more confidently in modern energy-efficient greenhouses. After all, if the glass is cleaned incorrectly and part of the light transmission is lost, this has direct consequences for production. The project shows which cleaning agents are safe for AR glasses and which are effective against contamination by chemical or microbiological dirt typically found on greenhouses.
