Sustainable Building Glossary

Dew point: Place where interstitial condensation occurs.

Diffusion: Movement of the vapour molecules. Between zones with different water vapour partial pressure, vapour molecules move because of the Fick‘s law: e.g. the cold outdoor climate in winter and the warm indoor climate/environment are dominated by different water vapour pressures. The resulting movement takes place in direction to the lower concentration.
