Greenhouses designed for hot climate geographical zones and hot periods of a year in both hot and cold climate geographical zones. The greenhouses are made with a specific coated glass allowing a very high hemispherical transmittance, a very high PAR transmittance and a tunable hortiscatter, when requested. The glazing contains a selectively high NIR reflectance and a high emissivity of glass, to allow the heat to leave the greenhouse to avoid a high temperature increase in the greenhouse. The glass can perform longer due to its durability.
