Indoor air quality is getting a lot of attention these days and most of us would agree that the air we breathe is important. But have you ever thought about why it is important? Here are 5 facts about indoor air quality that explains why it is important with a good indoor climate.
Good indoor air quality makes you smarter
Well maybe not exactly, but according to several reports, including Health, Wellbeing & Productivity in Offices, improved indoor air quality can increase productivity with around 10 %. Other studies shows that school children’s results can improve by as much as 13 % if their classrooms have a good indoor climate. So while fresh air might not make you smarter, it helps you reach your full potential.
We spend up to 90 % of our time indoors
This might seem as big number but if you work at an office for 8 hours a day and sleep 8 hours a night that’s 67 % already. Add the time for cooking, eating and socializing and 90 % isn’t that farfetched. So to say that indoor air quality is important is no exaggeration. Source
The indoor air can be up to 50 times more polluted than the outdoor air
A lot of things have been written about the pollution of our outdoor air, and rightly so. Our environment should have top priority. However, we seldom speak about the pollution indoors. Studies have shown that due to chemicals, machinery, fabrics and building materials used in our homes the indoor air can be 2-50 times more polluted than the outdoor air.
We consume a lot of air
We know that what we put into our systems have effects on our bodies, good or bad. It’s a clear trend that we are more aware of the things we drink and eat. But have you ever considered how much air you consume on a daily basis? The general rule is that every day we consume 1 kilo of food, 3 kilos of water and 30 kilos of air.
Have you changed your air today?
According to Survey on Minimum Ventilation Rate of Residential Buildings in Fifteen Countries the most common Air Change per Hour (ACH) is 0,5. This means that half of the indoor air should be replaced by fresh air every hour, or in other words that all air should be replaced 12 times per day. This is for the health of both building and people. Stale air can lead to condensation and mold in the building and to tiredness, headaches and trouble concentrating for the people in it. In the old days this wasn’t a big problem but now with our increasing focus on building well isolated air tight buildings to keep energy consumption down it’s almost impossible to reach this air exchange rate without a well-functioning ventilation system.
