Save energy by providing proper ventilation

The rise in VOC measurement values in indoor spaces is usually unpredictable, since around 85% of all room air deterioration is caused by the persons in the room. The remaining emissions are generated by the building materials or furnishings.

This uncertainty makes air exchange at a static ventilation rate anything but ideal.

If the ventilation rate...

• ...is set based on the VOC peak value, the excess air quantity exchanged on average gives off too much energy to the environment.
• ...is set to a low, energy-saving value, the permissible VOC limit will be exceeded at peak load times.
• ...is set to an average, the two drawbacks just named will be added together.

Only by monitoring the air quality can a need-based air exchange be accomplished: Then just the right amount of ventilation will be provided when it is needed.

Especially if the building does not have a ventilation system the Web-Graph Air Quality with its light indicator built into the sensor or using its alarm functions can help to prevent random ventilation and thereby contribute to energy cost savings.
