	This building technique can potentially used for [[greenhouse]] construction. This has been done and looks really good: see examples [http://ndbs.be.washington.edu/projects/2005sp/index.html here] and [http://longwoodgardens.org/history/1966-1976 here]. Such a "Lamella Greenhouse" may have somewhat lower solar gain than conventional greenhouses (due to the size of the wood panels, which may block some light), but would still be acceptable. Humidity might be a problem for the wood panels. This could be remedied with a double barrier (one transparent foil on the inside, one on the outside). This would have the advantage of providing extra insulation but would also raise the cost. ~~This~~ might be a good option for cold climates. It ~~seems like~~ a ~~good~~ alternative to [[3D Printed Multiwall Greenhouse Glazing]]. The Lamella Greenhouse could ~~also~~ be combined with the [[Walipini]] idea (i.e. earth sheltered greenhouse) as well as some kind of nighttime blanket for extra insulation (compare to: [[Chinese Greenhouse]]).

	A lamella roof, also known as the "Zollinger roof" (after [https://en.wikipedia.org/wiki/Friedrich_Zollinger Friedrich Zollinger]), is a vaulted roof made up of simple, single prefabricated standard segments as a way to span large spaces. The individual pieces are joined together with bolts and/or plates to form a rhomboid pattern~~. These elements were mostly in timber~~. Wooden sheathing covers the structure on the outside~~. Sometimes very similar roofs were built with steel (see paper linked below about buildings by Hugo Junkers)~~. The lamella roof was patented in 1910 and became popular between the World Wars, especially in Germany when metal for construction was in short supply. Some of these structures are now almost 100 years old and many of them remain in very good condition. In the 1950s, this concept was adapted to the construction of large dome structures by architect Gustel Kiewitt in the U.S.		A lamella roof, also known as the "Zollinger roof" (after [https://en.wikipedia.org/wiki/Friedrich_Zollinger Friedrich Zollinger]), is a vaulted roof made up of simple, single prefabricated standard segments (mostly in timber) as a way to span large spaces.
