• Heated greenhouse

: The first description of a heated greenhouse is from the Sanga Yorok, a treatise on husbandry compiled by a royal physician of the Joseon dynasty of Korea during the 1450s, in its chapter on cultivating vegetables during winter. The treatise contains detailed instructions on constructing a greenhouse that is capable of cultivating vegetables, forcing flowers, and ripening fruit within an artificially heated environment, by utilizing ondol, the traditional Korean underfloor heating system, to maintain heat and humidity; cob walls to insulate heat; and semi-transparent oiled hanji windows to permit light penetration for plant growth and provide protection from the outside environment. The Annals of the Joseon Dynasty confirm that greenhouse-like structures incorporating ondol were constructed to provide heat for mandarin orange trees during the winter of 1438.{{cite journal|last1=Yoon|first1=Sang Jun|last2=Woudstra|first2=Jan|title=Advanced Horticultural Techniques in Korea: The Earliest Documented Greenhouses|journal=Garden History|date=1 January 2007|volume=35|issue=1|pages=68–84|doi=10.2307/25472355|jstor=25472355|doi-access=free}}
