Light granite scored best in the measurements during the 6 months of testing. Granite is a highly attractive durable and easy to care for stone that will transform your home for the better.

Incorporates both solar reflectance and thermal emissivity in a single value. Level 1 granite has a very simple design and the colors are standard. Black and red rock granite albedo 0 19 3 white rock plagioclase albedo 0 49 and 4 gold and white rock chert iron impurities albedo 0 55 levinson 2001. You are practically guaranteed to find something that you like when looking for granite countertops or other home fixtures.

The measure for this is the albedo which also provides information about how much a surface warms up. The albedo of dark coloured wet and very rough soils ranges between 0 05 and 0 15 while the albedo of light coloured dry and smooth soils varies between 0 35 and 0 40 dobos 2006. This low grade granite is usually imported from china and sold through granite liquidators big box stores or cut into tile. Sri measures the roof s ability to reject solar heat defined such that a standard black reflectance 0 05 emittance 0 90 is 0 and a standard white reflectance 0 80 emittance 0 90 is 100.

This stone comes in a seemingly endless amount of granite colors and styles for you to choose from. Table 1 the approximated ranges of albedo of natural surfaces natural surface types approximated albedo blackbody 0 forest 0 05 0 2 grassland and cropland 0 1 0 25 dark colored soil surfaces 0 1 0 2 dry sandy soil 0 25 0 45 dry clay soil 0 15 0 35 sand 0 2 0 4 mean albedo of the earth 0 36 granite 0 3 0 35 glacial ice 0 3 0 4. As increasing the albedo is a strategy to improve thermal comfort santamouris et al 2012 wang and akbari 2016a the amount of albedo has changed to 0 7. The current situation pavement is composed of granite with albedo of 0 4.

The amount of incoming radiation which is reflected from the earth albedo has an important bearing on the earth s response to climate change. The albedo from the latin for white of the planet is an important feedback mechanism as extra ice can increase cooling or reduced ice can lead to warming. The albedo of different surfaces. Gray type i ii portland cement left albedo 0 32 and white type i portland cement.
