Type: The name of the surface type.
U-Value: The heat transfer coefficient of the surface.
ASHRAE Type: The surface type as defined in the 1997 ASHRAE Fundamentals Handbook. This value is used to determine the rate of solar heat transfer through the surface. See the ASHRAE Glass Zone, Roof, & Wall Types and Roof, Wall, and Glass Zone Type Tables articles in the knowledge base for more information.
Color: The color of the surface. The CLTD method recommends that you select Dark and not adjust the surface load based upon the color.
| • | Light: The surface is a light color. The cooling load will be reduced by 50% when this color is selected. |
| • | Dark: The surface is a dark color. The cooling load will be taken directly from the CLTD table with no scaling. |
