Abstract
For the world exhibition Floriade 2002 in The Netherlands a greenhouse design is developed by IMAG together with General Electric Plastics, Bergen op Zoom with polycarbonate double-web sheets with a zigzag-shaped surface.
Intensive research was completed to develop the special zigzag shape of the plastic sheets resulting in an enhanced light transmittance and energy saving of approximately 20% over the whole year.
The optimal dimensions for the sheets with respect to light transmittance, strength and insulation is a pattern of 50 mm for the zigzag shape, a thickness of 25 mm and the inclination of the pattern is 50°. The transmittance for diffuse light of the entire greenhouse with the double-web sheets is 78.8%.
