Today one out of six Europeans – or the equivalent of Germany’s population – reports living in unhealthy buildings, i.e. buildings that have damp (leaking roof or damp floor, walls or foundation), a lack of daylight, inadequate heating during the winter or overheating problems. In some countries, that number is as high as one out of three.
Unfortunately, it’s clear that living in unhealthy buildings has negative health effects. More than 1½ times as many people who live in unhealthy buildings have poor health compared to those who live in healthy buildings (see figure at left). This demonstrates a clear correlation between unhealthy buildings and people who have rated the parameter self-perceived health as ‘poor’.
