Growing up we had a skylight in our living room, but I never really understood how fantastic skylights were until I moved to the Southwest. Many homes here take advantage of skylights and it makes an amazing difference in the brightness of one's home and they are a big electricity saver too.
I first really noticed this when we moved into our home and our garage had a skylight in it. That means that you never need to turn the light on in the garage when you go in there during the day if the garage door is down. It's already light. I'm sort of surprised by this every time I walk into our garage because I have been so used to having to turn a light on in all the other garages I've had.
In the townhouse we lived in for a short time before we moved into our house there were skylights over the vanities in the bathrooms and it was wonderful to have that natural light when getting ready and looking in the mirrors. Another room where there are rarely windows and where you never needed to flip on the lights thanks to the skylights.
In this house we also have skylights in our family room and dining/living room and they make such a difference in the amount of light in those spaces. Albuquerque has an average of 310 days of sunshine a year, so we really get a great advantage to enjoying more natural light in our home and need less electrical lighting during daylight hours. The skylights have also really helped out our houseplants who seem so healthy and happy with the all natural light they get.
Skylights are not that expensive to install although I would suggest having a professional do it because it affects roofing and there can be problems with leaks if not installed properly. There are different versions that can be opened for additional ventilation too. Ours are opaque plastic bubbles, so they don't open but we have so many doors and windows in our house that can be opened that we really don't need that feature. But I sure do love our skylights, all the extra light they bring in just makes our home a happier place - and who does not want to save on lighting costs! Skylights are something I have learned to appreciate because of living in the southwest where they are plentiful. They are Big Like #7 this week.
