stephan8410 Jan 2011 15:04We will start building in April and have chosen 24cm (9.5 inches) hollow brick blocks with 12cm (5 inches) external thermal insulation. I would like to know if a ventilation system is really necessary to prevent mold growth in the long term and to ensure good indoor air quality. Unfortunately, even expert opinions differ on this matter.
Hello
A lot has already been written here about ventilation, controlled residential ventilation, and heat recovery ventilation (HRV). Just try searching.
Best regards

As already mentioned in another (green) forum:
Now I would like to know whether a ventilation system is really necessary to prevent mold growth in the long term and to ensure good indoor air quality.
Ultimately, only you can provide a comprehensive answer to this question.
In case of doubt, you can derive the necessary activities you need to be involved in from the ventilation concept provided by your contractor, which must be prepared according to DIN 1946-6. You should ask them about it!!!
You can find plenty of background information online for further reading.
Unfortunately, even expert opinions differ on this subject.

Hello Stephan,
In principle, modern houses are built increasingly airtight to achieve the desired energy savings. What is the use of an insulation panel if its connections are not properly sealed? None!
However, airtightness brings new challenges. The air inside rooms gets used up through daily activities and needs to be exchanged regularly. Additionally, humidity rises due to our breathing, cooking, pets, or plants, which in the past would have more or less dissipated through leaks.
As a result of this development, there is a fundamental need to handle modern properties differently. The "user manual" has practically changed, and occupants must follow certain rules to prevent problems such as mold growth!
This is where controlled residential ventilation systems come into play. Generally, these are not absolutely necessary if you follow the "rules" and ventilate regularly. Of course, this means money is lost in the form of energy through open windows, but at the same time, air quality and indoor comfort are maintained.
Like everything, controlled residential ventilation has advantages and, of course, some disadvantages worth discussing.
Advantages include, besides energy savings:
- automatic supply of fresh air
- no drafts
- prevention of mold growth
- noise protection, and
- pollen-free indoor air for allergy sufferers
Disadvantages may be:
- additional costs for the equipment
- not suitable for fresh air enthusiasts
- no specific subsidies
Ultimately, you need to decide whether a controlled residential ventilation system makes sense for you. It is essential to involve your energy consultant and planner, who will develop your concept based on your requirements and user behavior, legal regulations, and any applicable funding guidelines.
