I've discovered a social phenomenon in Israel, where people doing as much as possible to get rid of natural lighting and turning on artificial lighting indoors during the day. If by covering the windows with curtains, or by closing the windows shutters, or by other means. Look at these pictures: 1. https://www.lighting-gallery.net/gallery/displayimage.php?pos=-1461692. https://www.lighting-gallery.net/gallery/displayimage.php?pos=-172013These pictures are of exactly the same place of the dental clinic of Neve-Ram, which belongs to A.D.N.M company. However, in the first picture, they have blue ceiling that pass sunlight and daylight to the area, and in the second picture, they have a drop ceiling with LED lighting. This means that they installed this drop ceiling to get rid of daylight and sunlight, which are available for free and don't consumes artificial manufactured energy in favor of LED lighting which consumes artificial manufactured energy. This place is only one of lots of places here in Israel, where people trying to get rid of natural lighting in favor of artificial lighting. Are there another countries that people trying to get rid of natural lighting in favor of artificial lighting?

HID, LPS, and preheat fluorescents forever!!!!!!

At my high school, there were some painted windows that blocked out natural sunlight in favor of artificial lighting. I personally thought that it was a colossal waste of electrical energy.

In these cases the desire is not that much to get rid of natural daylight, but to not allow the solar heat to enter the building so generate excess load to the air conditioning. Spending electricity on artificial light may seem odd when there is plenty of sunlight, but mainly with the present light technology efficiency it cost less energy to operate artificial lights and make the building closed and so better insulated than to allow the sunlight in and then spend a lot of energy to remove the heat that creeps in along the sunlight. At least these days achieving that energy consumption level is today way cheaper by blocking all the natural radiation (both heat and light) to get in than to design some fancy filters allowing the light to enter but still blocking the heat. And saying that I'm not sure if it is even possible with present technology at all.

In some buildings, there are even some daylighting systems that help to bring natural daylight into the building to minimize the need for artificial lighting.

Resolutely crack down on inferior LED lighting!!

This problem is also very obvious in China: for example, some shopping malls can use glass roofs to absorb natural light, and install small lights on top of glass roofs to illuminate at night. However, most shopping malls use suspended ceilings to directly close the top, and instead use large-area soft LED panels. This is indeed an issue that cannot be ignored.

Why I asking the question... Because recently, the tutors of my hostel, began to close the shutters of the windows in my hostel, and turn on lamps during the day. When I ask them to turn off lamps and open the shutters, the refuse and asks me to go to my location in my hostel.

In some buildings, there are even some daylighting systems that help to bring natural daylight into the building to minimize the need for artificial lighting.
Bu the general problem with most of these is, they bring in the heat as well. So mainly in dry hot climates dealing with the extra heat costs more energy than the artificial lighting needs. There is no question about the natural light being vastly superior and even the system being more resilient towards shorter energy outages (the building thermal inertia can cover losing the cooling for a few hours without any extra equipment for that, but losing the main light for even few minutes means you have to close and evacuate), but these are not always the priorities for the building design. The build and running costs are and those are way lower in those hot climates without the daylight harvesting systems. The same is valid for the shutters: Opening them allows the daylight in, but as well the heat. Of course in colder climates, where you have to heat up the building, the situation is completely different.

No danger of excess heat getting in here, this part of the world never gets very warm, even in the height of summer

Scotland is very close to the arctic circle, and I bet you have white nights (Civil twilight at midnight) in the summer.

This is not a good practice. This is not only a waste of electricity, but also the light generally can not completely restore natural light, eye protection is much worse than natural light

As Medved has stated in a warm country like Israel, it's cheaper to use artificial lighting over running air conditioning.
