Publication number: 20170105363Abstract: A solar light type glass greenhouse includes a greenhouse unit. The greenhouse unit includes an under-eaves part including north, south, east and west lowersurface parts; and a ceiling part including a sloping roof on a north side, and south, east and west uppersurface parts. The sloping roof slopes by a sloping angle ? so that a south side is inclined upward when viewed from east. The sloping angle ? satisfies relations 15°<?<67°, and 63.6°-LAT???69.6°-LAT, where LAT is a latitude of an installation place. The sloping roof includes an eave extending to south beyond the south uppersurface part. A length of the eave is HS×sin(90°-?S)/sin(?S-?) or more, where ?S is a culmination altitude of the sun in the summer solstice, and HS is a sum of vertical lengths of the south lowersurface part and the south uppersurface part. The sloping roof includes a glass member having a heat reflective function.Type: ApplicationFiled: December 23, 2016Publication date: April 20, 2017Applicant: Asahi Glass Company, LimitedInventors: Naruaki TOMITA, Takehiro KOSE, Katsuyoshi NAKAYAMA, Shigetoshi MORI, Meiwen CHANG, Toshihiko HAYASHI
