That’s all I want to ask. It’s 2024, people. Shouldn’t all of our buildings have more skylights and windows at this point? Why am I still seeing buildings that have lights running during the day? Why are buildings still being built in ways where we need to rely on artificial light when the sun is shining?!? So much money and electricity could be saved.
Sunlight is proportional to the square of a building’s radius, but the light demand is proportional to the cube. This is assuming a relatively simple building design, of course, but that’s the basic answer. Just a matter of how the dimensionality scales as the building gets bigger.
