Daylight & Ultraviolet Radiation |
|
|
All energies that move at the speed of light are collectively referred to as electromagnetic
radiation or "light."
Daylight Most humans thrive in daylight. Incorporating this daylight into our green homes even has an effect upon our psychological health and our soul. It is part of green building. The energy from the sun can either be harnessed for our use or be a cause of overheating in our homes. Unfortunately, it is most often a source of overheating in Dallas-Fort Worth. Ultraviolet Light Various types of light differ in their wavelength, frequency and energy; higher energy waves have higher frequencies and shorter wavelengths. Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light. It has a shorter wavelength than that of violet light, hence the "unltraviolet" name. It is also called "black light," as it is invisible to the human eye. We need some ultraviolet radiation each day as UVB induces the production of Vitamin D in the skin. Yet this light is a major source of material damage, both inside and outside of the home, and must have consideration in green building. Balancing Act Because of overheating from the sun and the damage of UV light, there is a thin line for a green builder to balance in North Central Texas. Green building balances between having enough daylight to save electricity & soul, harnessing that energy for our benefit, and protecting our homes from overheating most of the year and protecting humans and homes from the harmful effect of UV radiation.
