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.
Because more windows would probably use more energy than having a more insulated building with lights.
Dual pane windows?
Depending on the area you might want to have triple pane windows instead, otherwise there is too much heat lost during winter. Double or triple pane windows don’t protect from the sun’s heat thought, so you would need additional shielding/dimming from that, which in turn will make it darker in your building. Hence I guess it’ll only work for buildings with lots of window space compared to the floor space, i.e., single family homes or other small buildings.
Not to mention cloudy days, or short days in winter, so the building would have to be fully wired for lights anyway. And dimmable for when they only need to supplement a cloudy day.
Natural light is one of those things that seem super obvious, until you spend pretty much any time actually thinking about it.
It’s not a thing because it doesn’t make sense to be a thing, not because no one thought of it.
