Mechanical Ventilation to Improve on the Energy Certification Scale

Fortunately, environmental care is increasingly considered in the construction sector. Many measures are being taken to make homes more efficient. In the following lines, we want to show you how mechanical ventilation can be used to improve on the energy certification scale.

• Why is mechanical ventilation important to improve on the energy certification scale?

All homes must have a ventilation system, whether mechanical or hybrid. It can never be natural ventilation. Ventilation has two different purposes:

• To eliminate humidity and CO2 from the home.
• To eliminate volatile organic compounds and other pollutants present anywhere in the home.

The fact that a home loses or gains heat influences the need for heating or cooling, respectively. The more heat is lost in winter, the more heating is needed. The more heat infiltrates in summer, the more cooling will be needed.

Of course, the more energy-efficient the home is, the better rating it will receive on the energy efficiency scale. Therefore, having a mechanical ventilation system is key to achieve that good rating.

• What does a mechanical ventilation system consist of?

In addition, it also filters the air coming from outside, resulting in less dust inside the home. Not to forget that it regulates humidity. For all of the above, a more comfortable indoor air quality is achieved.

For example, a mechanical ventilation system can transform the 13 degrees of outside air that crosses with the air exiting from the interior into about 21 degrees, making the air that enters the home at 20 degrees. This action would cause a consumption of around 17 W. No heating has been used to convert the 13 degrees from outside to 21 inside. This exchange process will only represent a few euros a month, depending on energy prices at that moment, but it surely won't reach even 5 euros. While using another type of heating would have raised that figure to at least over 50 euros.

In addition, it is an eco-friendly system and therefore cares for the environment, undoubtedly, a factor that must be considered when carrying out any type of construction.
