Thanks for an interesting summary of the issues surrounding borrowed light. This is a complex area that involves both planning and building regulations and as such simple solutions are not likely. Some points based on my research:
• Daily access to natural light is necessary to rest individual circadian regulation, the process that regulated the sleep/wake cycle. Artificial light is on a different spectral wavelength and is not effective for this task,
• Borrowing light requires larger windows in the primary room – this introduces compliance considerations under the BCA energy efficiency rules,
• More important than borrowed natural light in the question of borrowed ventilation and health. Where natural ventilation is not available (such as an openable window) and poorly designed mechanical ventilation is provided as a substitute, CO2 levels can easily exceed 2000ppm, which can potentially affect health.
Thanks again for an interesting article, but unfortunately I don’t think the review will examine the issues in the depth necessary to ensure good outcomes

GET OUT OF MY LIFE, YOU BASTARDS!

Whether I can see or not within my own dwelling, or even whether I'm healthy or sick, is none of your business - STAY OUT!

Judging by an inside look at the new apartment blocks (aka ant hills) going up here in Tichmond/Abbotsgord in Melbourne all I see is the latest addition to the next generation of slum buildings.The only thing that will stop them degenerating into slums is they are so shodily built that they will either be torn down or have a very major interior makeover within the next 10 years.

Q: Should natural light in apartments be more tightly regulated?

A: Yes

As far as I am concerned all bedrooms should have direct natural ventilation and natural light from outside the building. It is enough of a concession that many bedrooms do not have any allowance for cross ventilation.

We need to look beyond the immediate cost (and profit) of apartments to consider the quality of life and wellness of the occupants. Remembering too that bedrooms often serve dual roles as work and study centres.

You should worry, the light in my cave has never been worse, but only since the bats moved in and repeatedly put out the fire, with their continuing fly in fly out policy; and the sheer volume of steaming guano they seem to be continually adding to it, with every exit or entry.

You should see the callouses I've built up on my hands, rubbing two sticks together; well, I had run out of boy scouts, who ran off screaming into the night.

Well they were frightened off by the influx of bats, and knot even a dozen Swiss army knives tied to sticks with scout scarves, would discourage the bat invasion? Although one promising Don did "bat" a few for six!

Fortunately, the bats haven't yet discovered the nearby church or more importantly its belfry; otherwise the missus would be in a state of permanent bewilderment?

It's hard enough to have to listen to her almost permanent rendition of, my silver bells, as she drags in another log for the fire, without its literal accompaniment by the real thing.

On the plus side, the additional slightly scorched guano; has allowed me to triple the crop of non light dependent magic mushies, which by the way, makes the otherwise odious burnt bat stew a little more moorish.

Incidentally, the charcoal content seems to have taken care of a slight case of Mazuma's revenge/delly belly?

A dimmer switch on the solar furnace perhaps?

Well it would take care of climate change!?
