Pay attention to the dew point

Mold experts use a dew point calculator

The focus is on room air temperature and relative humidity

Visible mold growth in the apartment always causes discomfort for those affected. After all, no one wants to have the unloved co-inhabitant in their neighborhood. To analyze the causes, it is essential to take a look at the physical relationships in the building. The focus is on room air temperature and relative humidity as well as on the surface temperatures of the surrounding surfaces. Mold always grows when it finds enough food and sufficient moisture in its environment. The fungus is not choosy about its “food”. A little house dust is enough, as it can be found in every apartment. In the most frequent cases of damage, condensed water vapor from the air in the room is responsible for the influx of moisture. Mold experts use the dew point calculator to determine cause and effect.

Molds endanger people with weakened immune systems

The fungus Aspergillus fumigatus blocks messenger substances in the immune system

For healthy people, mold spores in the indoor air are normally no problem, since the pathogens are successfully controlled by the immune system. For certain groups, however, caution is required. The guideline of the Scientific Medical Societies (AWMF) includes people with a weakened immune system due to chemotherapy, stem cell transplants or HIV infections. Other risk groups include people with cystic fibrosis and bronchial asthma. The German Robert Koch Institute (RKI) divides the symptoms of immunosuppression into three groups and speaks of moderate, severe and very severe immunosuppression. In a recent study, scientists from the Friedrich Schiller University in Jena (Germany) have now found out in what way the mold can turn off the immune system.

Disastrous “low-budget” mold treatment

Recently made in the press a report circulating that many mold remediation are not conducted properly. “Three quarters of the architect, building surveyor, construction and renovation contractor and lawyers assume that 70 percent of the renovations are flawed,” reported the director of the Institute Peridomus Dr. Gerhard Führer from Himmelstadt/Germany. Even if there should be ten or twenty percent fewer cases, the incidence of improper renovations would be a disaster for the affected residents. So-called “brush renovations” mean nothing else than that the moisture damage was simply painted over. The new tenant sees the problem not at first attempt and the landlord has his first sleep.
