The surface color values L*a*b* of wooden facades of a building, exposed to a local natural environment, were sampled periodically for a period of 32 months in order to model the effects of different exposure conditions to the discoloration. However the discoloration by factors like UV, water and molds had been studied respectively, the discoloration of wooden facades associated with some building details under natural conditions is not enough studied. This study on the gradual intensity of discoloration in consideration of the distance to ledges and pavements and of the facade orientations provides realistic data needed for the color changing simulation of wooden facades. |
