How do paint colors effect your home
When summer comes around , can color reduce the energy consumption in your home?
Consider this: Would you be cooler wearing a light colored shirt or a dark colored shirt on a hot sunny day? If your science teacher or parents didn't convince you, the scientific fact is that white reflects the radiant energy rays of the sun and black absorbs them.
The same principle has a significant impact on a house. The hotter the roof, the hotter the rooms below. Light colored roofing or reflective coatings are like a light colored shirt for your house because they reflect radiant energy.
Even a light grey hue is better than a blue or green.The colors used inside a residence or workplace can also save on energy costs. The Environmental Protection Agency reports that electric lighting accounts for 25% of the electricity used in the U.S.A.
The same principle, the lighter the color the higher the reflectivity can be applied. Dark walls absorb more light and reflect less. Consequently, far more lighting is required for rooms with dark walls than those with light walls. In addition to the walls, it is a good idea to keep the ceiling light and bright for good reflectance.
Some major paint manufacturers can tell you the Light Reflectance Value (LRV) of any color paint chip. White reflects 80% of the light, black 5%. Therefore, the higher the LRV number of the paint color, the less artificial light you will need.
Caution: Don't go overboard. An extremely high lighting level combined with very light walls is bad if it creates glare, or too much brightness on the wall. This causes excessive stimulation and irritation of the eyes. Eye fatigue will follow.
