The north glazing is not shaded and permits indirect natural light to enter
(Torcellini et al. , 2010).
7.4.2.3 Daylighting and Electric Lighting
The daylighting window is equipped with a light-reflecting device, the
“Lightlouver™.” Incoming transmitted solar radiation is reflected toward
the ceiling, and then diffusely reflected again deeper into the space, onto the
workplane(asshownin Figure7.50 ).Thishasthesecondarybenefitthatthe
occupants adjacent to the window are protected from direct solar radiation
for nearly the entire year. Thus, movable shading devices (e.g., blinds) were
not installed. The view window portion is equipped with exterior shading,
