Abstract: A method is provided for modelling irradiance levels in a solar light type glass greenhouse, the greenhouse including a plurality of glass panels having at least one glass panel type, and the greenhouse having an intended geographical location and intended orientation. The method includes: providing a three-dimensional structural model of the greenhouse, the structural model containing: modelled glass panels, modelled structural components, a modelled intended geographical location, and a modelled intended orientation; determining at least a first set of characteristics for the modelled glass panels and a second set of characteristics for the modelled structural components; providing a set of environmental data; using a rendering component to determine an irradiance map of the greenhouse based on the 3-dimensional structural model, the at least one first and second sets of characteristics, and the set of environmental data; and optimizing the irradiance maps based on a set of optimization criteria.

Abstract: The present invention discloses a glazing characterized through a high hemispherical light transmission together with an enhanced tuneable light diffusion, what we hereby call a highly transmitting glazing with optimized Hortiscatter. The glazing of the invention is particularly well suitable for a greenhouse.
