Indoor climate and personal ventilation
A lot has happened in indoor climate in homes, offices and schools. We now know exactly what good indoor climate is. Or, to put it another way, we can predict how many people will be happy with the indoor climate in a room. And that way, we also know what needs to be changed to get even more approval for the indoor climate.
When assessing the indoor climate of a room, you look at the following:
- Temperature
- Air movement (draughts)
- Light (how much daylight)
- Sound (both internally and from the outside)
- Air humidity
- The air's purity (CO2 level)
It's hard to please everyone
The way to measure how good the indoor climate is, is to see how many people are dissatisfied. The more dissatisfied people there are, the worse the indoor climate. If only 10% are dissatisfied, the indoor climate can be designated "good". Usually it's impossible to create an indoor climate which everyone is happy with, as we all have our preferences and everyone dresses differently.
