Modern people spend up to 90% of time indoors. Indoor air quality is therefore of key importance for our well-being, health, and the quality of life. Air temperature, room surface temperature, airflow, and air humidity have a significant impact on indoor climate.
Modern buildings are often designed as low-energy or passive houses. That is why they are becoming more and more air-tight, providing optimal thermal protection and reducing the need for additional heating. This also partially prevents excessive heat gain in the summer, of course, when the sun protection of the windows is optimally realised. In previous decades, summers have become hotter in our geographic area, resulting in unpleasantly overheated interiors, which cannot be cooled down by simple ventilation. Overheating is critical, especially if the construction is made entirely of lightweight assembled structures without the use of massive building materials that can accumulate heat.
Ideally there should be a different but stable temperature in the each room of the apartment

Strong fluctuations in humidity and temperature, too little airborne ions, air currents and an increased amount of fine pollution particles can lead to a damage of the respiratory tract, impaired lung function and cardiovascular diseases.
Molds, bacteria, viruses, parasites and allergens in the air. Allergens come into play with house dust, mold spores, animal epithelia, building materials or plants. They can cause nose and eye inflammation, runny nose and asthma.
Smells, solvents, formaldehyde, CO2, VOC and smoke. Unpleasant smells can come from furniture and floor finishes, drainpipes or from the outside. It disturbs the personal well-being and even causes stress.
