The physics behind white roofing is quite simple. Solar energy delivers both light and heat, and the heat from sunlight is readily absorbed by dark colors. Lighter colors, such as white, reflect back a sizable fraction of the radiation, helping to keep a building cooler. They also re-emit some of the heat they absorb.
White Roof Studies
Many conducted studies, organizations, and experts back the energy efficient benefits of white roofing systems.
A 2009 study by the Lawrence Berkeley National Laboratory’s Heat Island Group found that retrofitting 80% of air-conditioned buildings in the United States with white roofs would save $735 million annually in reduced energy bills. According to the Lawrence Berkeley National Laboratory Heat Island Group in Berkeley Switching to a white roof can actually reduce energy use by about 20 percent in the hot, summer months.
“Studies show that white roofs reduce air conditioning costs by 20 percent or more”
“Whitening the world's rooftops and roads would have the same effect on global warming as removing all the world's cars for 11 years”. - Energy Secretary Steven Chu
Standard in the Industry
In the United States, white roofs have become the standard for their energy efficient principles. Large corporations such as Wal-Mart have taken advantage of the benefits of white roofs. More than 75 percent of the chain’s outlets in the United States now have white roofs. More and more corporations are enjoying the benefits of installing white roofs, and the trend is steadily increasing.
