We are becoming more and more aware of the consequences of global warming. We know that we ourselves can do something to counteract this. We can, for example, travel less often by car, eat less meat and use energy more efficiently. The government has helped us with the latter. For example, there is a subsidy available for taking energy-saving measures for housing. Since then, modern homes have been insulated so well that no heat can be lost through cracks and holes. However, when the house is properly insulated, no heat can be lost through cracks and holes. The downside is that no fresh air enters the house this way. However, we do need ventilation to stay healthy. On the other hand, we also want to make sure that the environment doesn't suffer even more. In this blog we answer the question whether ventilation is environmentally friendly.
Ventilation systems A, B and C ensure that heat is lost in the house, like simply opening a window does. The advantage of the ventilation systems over opening a window is that the air actually gets ventilated. This keeps us and our home healthy. Do you want to know exactly when a room needs ventilation?

When you ventilate, colder air enters the house. However, this air is drier than the air inside (even when it rains). Ventilation ensures that your home heats up faster, so you don't have to use the heating system as much. The reason for this is that moist air warms up less quickly than dry air. Humid air is created by daily activities such as showering and cooking. Besides the fact that a house heats up more difficultly, damp air also causes mould and is harmful to your health.
However, air that is too dry is not pleasant either. Especially in winter, the air outside is very dry. Read about the consequences of too low humidity here. A MVHR system with enthalpy ensures that, besides heat, also moisture is recovered from the air. The enthalpy exchanger therefore maintains the humidity in the air, whereas a humidifier actually adds moisture. The ideal humidity in the house is between 40 and 60%. This humidity level can also be measured with some CO2 meters.
The solution to reduce costs and be environmentally friendly
A MVHR system meets all requirements. This system ensures that the house is properly ventilated, that as little heat as possible is lost and you save on costs. If you want to live even more energy-efficient, you can choose ventilation. This way, the system only ventilates more when the CO2 level in these rooms requires it.
