The energy-saving sun-light greenhouse is the most successful and unique facility in protected horticulture in China. This type greenhouse is very different from normal pipehouse or glasshouse in the structures, in which there are three-side non-transparent walls. The energy resource of the greenhouse comes mainly from the solar radiation that is the reason why they were named as sunlight greenhouse. Because the wall's powerful thermal reservation, very fruit vegetables such as cucumbers, tomatoes can be planted in the sun-light greenhouses without heating or only with little heating in the winter in north China. In this paper the development, basic structures and environmental characteristics of the sunlight greenhouse are introduced.
