| Abstract: |
| The humidity of room air is a necessary influence of design under the aspects of thermal behavior, technology and conservation.
The moisture absorption in the walls through sorptive materials or dehumidification on the cold window surface by dew point condensation is low because of the new thermal characteristics of these components.
The moisture load of a room briefly or also continuously, caused by technological processes or the users can't be compensated.
Today, the walls are used like a floor heating system. New developments refer to the fact that in the near future the wall will be used like a chilled ceiling system.
The authors would like to show the danger of downward air streams and the condensation of water caused by chilled walls.
The distribution of temperature, velocity and humidity of room air, calculated with a three-dimensional mathematical program, is shown. It becomes clear, that it is necessary to realize an integral process of design by co-working of architects, users and engineers to avoid problems of humidity and to give the guarantee of thermal comfort.
