More specifically, this means that a ventilation measure is required if a defined minimum volume flow for moisture protection can no longer be ensured by the volume flow given by infiltration on average during a heating period. In practice, this leads to preventing mould infestation and moisture damage.

Factors influencing the comfort zone

Nasty smells in the room air

Nasty smells in the indoor air are caused by so-called 'volatile organic compounds' (VOC). The air people breathe in contains various compounds such as alkanes, alkenes, terpenes, esters, naphthalene and many others. These compounds can be further classified according to their boiling range: Some substances are highly volatile, others are slightly volatile whilst some are hardly volatile. This is similar to moist rooms: Moisture can occur in solid form (as ice), in liquid form (condensed) or in gaseous state (in the air). Consequently, the fact that nasty smells have a negative effect on our well-being is obvious.

Temperature and humidity (climate)

The humidity level of a room is mainly influenced by everlyday life activities, such as washing, cooking and showering. Especially in the cold season, this fact is often visible at windows. But did you know that each person in a room emits approx. 30 - 40 g of water per hour, even during light activity? The higher the temperature of a room, the more water we humans emit. Even indoor plants release plenty of moisture. For example, a rubber tree with a height of 1 m produces approx. 4.4 g of moisture per hour. Rooms, flats and offices, are sensible comfort zones for people, combining the prevailing room temperature and the relative humidity of the air. 

Temperature and humidity measurement directly on the brickwork and in cellars - just in case you are facing mould infestation

A climatic status recording, i.e. temperature and humidity measurement in case of bad odours, mould formation or damage due to humidity is absolutely necessary. If the values were recorded over a period of several days, specific conclusions can be drawn about the ventilation behaviour of the people in the room or building concerned.

Mould prevention and dehumidification of cellars and basements

Inadequate ventilation leads to mould growth. In order to avoid this, there are compact and intelligent solutions providing for an optimum feel-good climate. Our devices work fully automatically, user-independently and thus significantly contribute to the protection of the building concerned and its environment. In this context, ZILA uses the technological approach of comparing the absolute humidity indoors and outdoors. For this purpose, the measured parameters temperature and relative humidity are measured by means of climate sensors, which record both values in one sensor. From this, the absolute humidity can be derived. If the absolute humidity outdoors is lower than indoors, ventilation is recommended in order to dehumidify the room air. Furthermore, we recommend  CO₂ concentration measurement. For mould prevention and basement dehumidification, ZILA also offers innovative products and solutions.

Our product range includes:

• Climate and ventilation controls for dehumidification and ventilation of cellars/basements, flats, offices, classrooms and conference rooms.
• Solutions with special climate requirements
• Ventilation control with CO₂ sensor technology to detect hazards for machines and plants
