Increasing Brightness in Alleyways

Caption

This is a simulation of the illuminance of an alleyway at noon at two different times of year, autumn (top) and winter (bottom). The new light-directing panel increases the amount of light that reaches the alleyway, as indicated by the higher amounts of red and yellow in the right-hand images ('with panel') compared to the left-hand images ('without panel').
