WebThe amount of energy reflected by a surface is called albedo. Dark colors have an albedo close to zero, meaning little or no energy is reflected. Pale colors have an albedo close to 100%, meaning nearly all the energy is reflected. Forests, for example, have an albedo of about 15%, which means that 15% of the sunlight that hit a forest is ...

A cool roof is designed to reflect more sunlight than a conventional roof, absorbing less solar energy. This lowers the temperature of the building just as wearing light-colored clothing keeps you cool on a sunny day. Conventional roofs can reach temperatures of 150°F or more on a sunny summer afternoon, sun. hudson news trade show 2018
