Separate search groups with parentheses and booleans.
Forest floor spectral properties are an important driver of top of canopy toc bidirectional reflectance factor brf.
Especially the rear area of the room which isfurthest away from the window benefits enormously from bright surfaces because most of the light will be reflected off the floor walls and ceiling before it reaches deep into the room.
In fact in an existing space with a large area of dark surfaces can improve light levels and visual comfort almost immediately by simply repainting those surfaces a lighter color to improve reflectance and thereby improve coefficient of utilization an expression of efficiency of a luminaire in a given application and an important factor in.
