A simple, inexpensive method to make use of solar power would be natural day lighting, so that you utilize sunlight rather than electric lights throughout the hours of sunlight. You can do this with windows, traditional skylights, along with a relatively recent kind of tubular skylight. Natural daylighting might appear to be good sense and hardly something you'd need to arrange for, but that is incorrect.
To get probably the most take advantage of daylighting, care must be directed at building geometry, window and skylight locations, and also the arrangement of furniture and internal spaces within rooms. For instance, if you really are a morning individual who loves to read the paper in the kitchen, it might make sense to create the home using the kitchen on the east side of the house where it'll get plenty of morning light. If you have kids who'll be playing in the family room after school, locating that room on the west side of the house allows it to profit from afternoon light.
On the contrary, if family members will rarely be home throughout the daytime, perhaps it does not make as much sense to cope with daylighting design; focus your efforts elsewhere.
In making effective utilization of natural daylight, bear in mind that design conflicts will come up. For instance, skylights or roof windows could be well suited for daylighting, however they may also result in significant heat gain throughout the summermonths, particularly whenmounted on south-facing roofs; they are able to thus significantly increase ac costs or reduce comfort.
If you intend to include skylights in your house design, think about which kind of glazing they ought to have. High-performance, low-solar-heatgain glazings can be found that will lessen the energy penalty of skylights significantly. Clerestory windows work very well for both daylighting and passive solar. They are vertical windows extending up in the roofline that bring sunlight deeply right into a house, plus they are particularly wellsuited to flat-roof house designs, that are more common in the western US.
The most recent development in residential daylighting may be the introduction of tubular skylights. They are round skylights installed on a roof and attached to living area with large-diameter reflective tubes. The tubes can extend through attics, providing light to bathrooms, hallways, or bedrooms below - even if six feet or more of attic separate the rooftop in the ceiling.
Since most tubes are under 16 inches in diameter, they are able to conveniently fit between roof trusses or rafters, to allow them to be installed without making structural modifications, out of the box often required when larger skylights are installed. In the room below, you simply begin to see the diffuser; it's just like a ceiling fitting. Some tubular skylights more effectively control heat loss than the others.
