NOVELTY - An energy saving glass comprises mutually parallel first surface (1) and second surface (2), in which energy saving glass the glass mass (101) contains a solar radiation energy absorbing agent present in a layer (103) of the glass mass which is close to the first surface, in which layer the concentration of the radiation energy absorbing agent decreases when proceeding from the first surface deeper into the glass mass, such that the absorbing agent is present at the depth of at least 0.1-100 micrometres as measured from the first surface of the glass.    USE - As energy saving glass; as a window glass of a building; in glass production line (float line) in which the glass is heated, such as tempering or bending line; in a line that is separated relative to the glass production line and in which the glass is heated (claimed).    ADVANTAGE - The energy saving glass is suitable for reducing energy consumption in areas in which cooling the buildings (air conditioning) causes considerable energy consumption, and in areas in which both heating and cooling are used in buildings; and can be used in locations where the window comprises a single glass pane. The solar energy absorbs into a layer as thin as possible on the surface of the glass facing the outdoor air. The method allows in the sampe process the production of low emissivity coating on the opposite surface of the glass.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for making the energy saving glass, in which solar radiation energy absorbing agent is arranged into the glass mass at an increased temperature of the glass mass, layer (104) of particulates is grown on first surface of the glass, which particulates comprise at least one element or compound of the elements and diffuse and/or dissolve into the surface layer of the glass, so that at least one element dissolving from the particulates modifies the surface layer of the glass such that a solar radiation energy absorbing layer is formed on the surface.    DESCRIPTION OF DRAWING(S) - The figure shows cross section of the energy saving glass.    First surface (1)    Second surface (2)    Glass mass (101)    Surface layers (103,104)    Low emissivity coating. (105)
