Energy saving in a greenhouse with insulated glass requires a significant investment. In the search for a cheaper alternative, a consortium of companies comprising VDH Plastic Greenhouses, Van der Valk Horti Systems, AGC Chemicals Europe and Boal Systems developed a Glass-Film greenhouse cover in the summer of 2014, and is better known as the 2SaveEnergy concept. The combination of clear glass with a diffuse ETFE film and a double screen positioned just a few centimeters apart, resulted in low energy consumption and good tomato production in the 2015 cultivation year. The Next Generation Cultivation principles were adhered to as much as possible. Compared to standard practice, energy consumption was over 50% lower with at least equal production.
