Reaearch projekt: raum/klima/putz

In the project „raum/klima/putz” four institutes of KIT examine specifications of a moisture-regulating indoor plaster. In respect of a changing climate in Baden-Württemberg this plaster is supposed to improve the indoor room conditions by ab- and desorption of moisture in a passive way (i.e. without active air-conditioning). Under the project management of the Institute for Meteorology and Climate Research the Institute of Concrete Structures and Building Materials, the MPA Karlsruhe and the Building Science Group (fbta) work together in the project.

fbta is responsible for the investigation of the indoor climate and its impact on the comfort of the user. The perception of comfort of test persons is examined under summer conditions with raised air humidity is examined in the test facility LOBSTER and current standards on comfort are compared with the results. Further, computer simulations will be performed, which include adapted weather data files, internal moisture sources, ventilation behaviour by the occupant and physical parameters of different plaster materials to generate profiles of air temperature and moisture with hourly resolution. Those profiles will then be evaluated according to the specified comfort limits.

The project „room/climate/plaster” with a duration of 3 years is funded by the Baden-Württemberg Foundation and started March 2015.
