Why and when to ventilate?

As we spend about 90% of our lives indoors, the indoor climate is extremely important for our well-being, therefore it can be clearly said that we ventilate for health and comfort of building occupants. Buildings — the same as humans — need to also breathe to make sure that fresh air comes in and dirty air goes out.

The building needs to provide a suitable environment for people and their activities: such as living, working, educating, playing, entertaining and physical activities. Ventilation is one of the systems that keeps our indoor environment habitable, keeping the air fresh and healthy indoors.
