colour (of surfaces)

When walls or exposed roofs (either flat or pitched) are selected then the colour (and hence reflectance values) may also be defined by clicking on the Define Colour buttons in both the Wall Details and the Ceiling Details forms. Scientifically, varying reflectance as a function of surface colour is described under the phenomenon known as albedo factor.

Please make no mistake. Contracts have been won or lost and installations have failed because of poor understanding of reflectance and Albedo factors!

Is colour important?
