I understand the bedrooms, but in the bathroom people ventilate anyway after showering, and in the kitchen too because of odors. Since my husband is a smoker, he goes out to the terrace every evening, which also ventilates the living and dining area...

• Bathroom – do you really ventilate long enough until all moisture is gone ... even at low outdoor temperatures?
• Kitchen – odors and fumes don’t just disappear. A cigarette – I’m a smoker myself – is quickly finished; are the fumes and odors eliminated in that time, and does your husband leave the balcony/kitchen door open in winter accordingly?
• Living room – every person releases about 10 liters (2.6 gallons) of water into the air, in your specific case into your living/dining area x 2 and without children. Do you believe this moisture can be cleared from the air just during your husband’s smoking breaks?
• Remaining construction moisture – even though nowadays bricks or blocks are usually glued together, the screed needs water... and quite a lot. Although the heating system should reasonably be started during the drying process of the screed, a residual moisture always remains in the house, which is intensified by the factors mentioned above. Do you think you have the time in the first year to ventilate at least 4 times daily for 10 minutes each time?
