Abstract To find whether Choson Greenhouse provides functions and thermal environment for planting or not, the thermal performance was measured and analyzed in the greenhouse. As measurement results, sunlight entered in the greenhouse, passing through the oiled Hanji cover. As it reached the soil of floor and wall surfaces, and it absorbed the sunlight’s energy. Once absorbed, some of the energy passed back into the atmosphere, but much of it remained trapped in indoor space by the greenhouse effect. We found that Choson Greenhouse keeps warm to grow plants with the rise in temperature, and the oiled Hahji is distinctly suitable for a role of thermal insulation, sunlight transmittance. Also, the thermal performance was compared a Hangi-covered greenhouse model with a vinyl-covered greenhouse model. The Hangi-covered greenhouse model was better for ventilation, thermal insulation and humidity control?? than the vinyl-covered greenhouse model. Therefore, Greenhouse in early Choson dynasty can be fairly evaluated as the extraordinary farming facility compared to nowadays greenhouses.
