From the Input Output Reference, how about those outputs?
1.9.44.13 Surface Window Transmitted Beam Solar Radiation Rate [W]
1.9.44.14 Surface Window Transmitted Beam Solar Radiation Energy [J]
The solar radiation transmitted by an exterior window whose source is beam solar incident on the outside
of the window. For a bare window, this transmitted radiation consists of beam radiation passing through
the glass (assumed transparent) and diffuse radiation from beam reflected from the outside window reveal,
if present. For a window with a shade, this transmitted radiation is totally diffuse (shades are assumed
to be perfect diffusers). For a window with a blind, this transmitted radiation consists of beam radiation
that passes between the slats and diffuse radiation from beam-to-diffuse reflection from the slats. For a
window with a screen, this value consists of direct beam radiation that is transmitted through the screen
(gaps between the screen material) and diffuse radiation from beam-to-diffuse reflection from the screen
material.
For each zone time step,
Surface Window Transmitted Beam Solar Radiation Rate = Surface Window Transmitted Beam To
Beam Solar Radiation Rate + Surface Window Transmitted Beam To Diffuse Solar Radiation Rate
Surface Window Transmitted Beam Solar Radiation Energy = Surface Window Transmitted Beam To
Beam Solar Radiation Energy + Surface Window Transmitted Beam To Diffuse Solar Radiation Energy
