Lighting strategies

user-1044545 | Posted in Green Building Techniques on

i could not find this on any other forum and hopefully my post is relevant

Is there a way to get natural sunlight into a dark room? I have a 1st floor living room in an attached house (attached from both sides) and this room runs north south and has some windows on the south-facing side. Could I use some technique to light up the whole room using these windows? I see a technique listed here but it needs direct access to the roof

    If you want natural light in the center of your house, you're going to need a skylight -- either a conventional skylight or one of the newer tubular skylights -- and that means, of course, you need access to the roof.

    Here are two articles on tubular skylights:

    Instead of running the tubes from the roof, can I instead point it somehow on the south-side facing windows?

    Q. "Instead of running the tubes from the roof, can I instead point it somehow on the south-side facing windows?"

    A. No. That wouldn't really work, and such an installation would be contrary to the manufacturer's installation instructions. Of course, if you have $10,000 (plus a little more for installation costs), you could install a fiber-optic lighting system: Fiber Optics for Daylighting.

    I would suggest working with watcha got. What is outside that south facing glass? What color are your walls? Ceiling? Floor?

    I have wood ceilings and it is amazing how much dimmer it is than a house with white ceilings.
