Abstract

Mold growth is one of the first signs of too high moisture conditions in building structures. A numerical method has been developed at VTT to simulate numerically mold growth on wooden structures and to evaluate the growth using mold index levels that can have values between 0 and 6. It has been further developed to take into account less sensitive building materials. This simulation model can be used to predict the risk for mold growth and it can be applied as a post-processing tool for moisture simulation models. Now the mold index is considered to be applied in ASHRAE Standard 160 as improved moisture performance criteria. The workshop was organized to present the contents and use of the model.
