Finished attics and bonus rooms typically appraise at 100% of the value of the rest of your living space while basements typically do not.

Bright light regulates the suprachiasmatic nucleus clock. Known by most as our bodies internal clock. This clock keeps our bodies set to the correct time.

Electric lighting accounts for one-fifth of the total electrical energy used in the U.S.

Students perform significantly better in environments that are lit with natural, rather than artificial, light. The study, one of the largest of its kind, tracked test scores for 22,000 students in California, Colorado and Washington. Researchers report that learning rates were 26 percent higher in reading and 20 percent higher in math in rooms with the most natural light.

20% of our population suffer varying degrees of Seasonal Affective Disorder (SAD). Individuals with SAD may experience emotional depression, a drop in physical energy, an increased appetite, and an increased need for sleep. Lack of sufficient daylight is directly linked to SAD.

As you age, the lenses of your eyes thicken and the pupils shrink in size, causing your eye to adapt much more slowly to changing light conditions. Researchers McFarland and Fisher reported that to accommodate the adaptation of the aging eye, the amount of light required for visual acuity doubled for each 13 years after the age of 20. It is clear that softer, natural light equals better vision.

American homeowners said if they had a choice of accessories for the ultimate dream bathroom, No. 1 on the list would be a skylight to bathe the bathroom with more natural light.

That studies comparing natural daylighting to conventional electric lighting show that students who attended elementary schools where natural daylighting is used have better attendance, better dental records and grew more - 3/4” more over a 2 year period.

That people need vitamin D for calcium to be absorbed by the body to strengthen teeth and bones and other tissue to maintain a healthy skeleton throughout life. Two sources of vitamin D are diet and sunlight. In healthy human bodies, 80% of vitamin D is developed through exposure to natural light. A vitamin D deficiency could result in the brittle-bone disease osteoporosis, which affects mostly women. Skylights and milk - a winning combination!

That "Sick House" symptoms develop because the house literally can't breathe. As a result, it gets congested with internal pollutants or Volatile Organic Compounds (VOCs). Common sources of pollutants (VOCs) in the home are adhesives, upholstery, carpets, furnace exhausts, fireplaces, pressed wood cabinets & cupboards. VELUX venting skylights allow your house to breath!

Often described as that pleasant, "new smell," VOCs can be harmful. Short-term exposure to VOCs can cause headaches, nausea and irritate eyes, throat and nose. New houses are insulated and sealed so well that no fresh air enters in. Moisture builds up but can't escape and that makes a perfect breeding ground for mold.
