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.

The role of gender in the case of fogging

Excessive use of candles and tea lights

Fogging is understood as ghosting black dust deposits, which can partly occur overnight in apartments. The oily, greasy deposits on walls and furniture can only be cleaned with great effort. Diploma chemist Martin Wesselmann from Hamburg sees a gender-specific problem group among those affected. In 62% of the households surveyed by Wesselmann lived women and in 33% couples or families. Only 5% were pure male households. The excessive use of candles and tea lights is the main cause of black dust. The gender-specific allocation of causes is based on 132 dwellings.

Wall heaters require a relatively small area

Wall heater combined with clay

Depending on the insulation quality of the house and the height of the flow temperature, a wall heating system needs between 20% and 35% of the living space. However, this is not the only difference to underfloor heating, which generally requires one hundred percent of the living space.
Underfloor heating systems react more slowly to climate changes, require higher flow temperatures and cause dust swirling. As a result of the smaller area requirement, the client saves installation material for wall heating systems, thus lowering the production costs. Wall heaters radiate radiant heat and can be combined with clay or lime. You will find several reasons to deal with this technique in more detail.

Which components affect our indoor climate

Hobo data Loggers

Dataloggers measure the room climate

Introduction – The climatology is one of the most difficult areas of science. Air, temperature and electric climate influence each other more or less – and these factors are in turn influenced indoors of building materials, construction and electrical installation. Although cooperating the individual components of indoor climate, it will be discussed for better presentation separately. Now read which components affect our indoor climate.
