 ====== Ventilation ======
-The health and comfort of the inhabitants are the most important objectives of a Passive House design. Excellent indoor air quality is indispensable. But this can only be achieved if stale air is exchanged with fresh outdoor air at regular intervals. This can definitely not be done by just opening windows twice a day. Ventilation will work accurately only if stale air is removed constantly from the kitchen, bathrooms, and all other rooms with air pollution. Fresh air has to be supplied to the living room, children’s room, sleeping rooms, and workrooms to substitute the removed air. The system will supply exactly as much fresh air as is needed for comfort and for good indoor air quality; only outdoor air will be supplied – no recirculated air. This will lead to a high level of indoor air quality. Read more about:

 [{{ :picopen:hausgrafik_lueftung_daemmung_2023_en.jpg?nolink&300x305|The basic principle of Passive House ventilation moist, stale air is extracted from the kitchen and the bathrooms(extract air) while fresh air (supply air) flows into the living areas.}}]
 ==== Ventilation Units ====
-The ventilation units provide clean, pollen-free and dust-free air while eliminating excess moisture and odours. In the winter, heat from the warm, stale air(extract air) isn't transferred to the cold, incoming, outdoor air, thus reducing heat losses considerably. In the summer, the system can work to a certain extent in reverse, pre-cooling the fresh air that is supplied to the building. Depending on the efficiency of the heat exchanger, over 90 percent of the heat can be transferred, allowing the supply air to come in at nearly room temperature. The basic principle of Passive House ventilation: moist, stale air is extracted from the kitchen and the bathrooms (extract air) while fresh air (supply air) flows into the liviing area. As a resut, the hallways are automatically ventilated. As a general rule, the ventilation system should be designed to provide 30m<sup>3</sup>   of fresh air per person per hour. For a living space of 30m<sup>2</sup>   per person, this equates to a supply air volume of 1 m<sup>3</sup>   /(m<sup>2</sup>   h). The maximum temperature to which this supply air can be heated is limited to 50**°**so as to avoid odour problems resulting from burnt dust particles. The resulting maxi, um heating load amounts to 10W/m2, which can easily be met via the supply air.
+The ventilation units provide clean, pollen-free and dust-free air while eliminating excess moisture and odours. In the winter,the fresh supply air is preheated  and can thus be brought into the building at a temperature of 16°C and the heat can remain in the building. On hot summer days, on the other hand, the supply air is cooled (almost) to room air temperature by the heat recovery. The high-quality ventilation unit ensures that the supply and exhaust air ducts in the heat exchanger are leak proof, so that fresh and used air is never mixed. The high-quality ventilation unit saves much more energy through the prevention of heat losses than they use to run.  Check [[https://passipedia.org/certification/passive_house_suitable_components|Component certificate criteria]] and[[https://database.passivehouse.com/en/components/list/group_2?| certified ventilation units ]]to see all the high-efficient components.

 ==== Air flow rate ====
-The appropriate air flow rate in the ventilation system is to ensure the proper functioning of the system and to achieve comfortable indoor conditions. It is essential that not only the planned volume flow rates are achieved in individual parts or rooms of the building, but also that a balanced mass flow between the exhaust and extract air is ensured.
