In spite of everything, because there is a correspondingly large impact on healthy construction and this then raises the question of what creates, how can healthy living planning be implemented? Which factors play a role in this?

The fact that the relevance, the importance of healthy living planning and healthy living design has increased significantly in recent years, has almost a small paradox as a background. We now have technologies to energetically equip our buildings in such a way that they barely consume any energy. Ideally, even be able to produce energy.

But we can only achieve the whole thing if our facades, our room envelopes, become ever denser. Old buildings, not just over the windows, often had a certain amount of air exchange, as there were crevices and cracks. Accordingly, there was always a certain exchange of air quality with the prevailing outdoor air quality.

As a result of energy optimization, the building envelopes become denser. This logically means that the interior, the lock and, accordingly, the materials used here have a completely different effect, because the otherwise regular exchange of air no longer takes place in this way. So on the one hand, the more we build in an energy-optimized way, the more important it is to actively, consciously consider healthy living, as the right materials are used accordingly.

The main goal of planning with a focus on healthy living is to protect against hazardous substances and avoid polluting building and finishing materials. Protection against hazardous substances is classic depending on the building, it is of course a big difference whether you plan and build an apartment or an office space, a restaurant, a factory, where hazardous substances are often handled. However, hazardous substances play a role even in residential buildings.

In Germany, for example, we have loads coming from the soil in quite a few places, be it from contaminated sites, or even from natural radiation radon, etc. Accordingly, it is important to protect future users from this. In the end, when avoiding polluting building and finishing materials, it is quite simply put, I define the choice of materials as meaning that wherever there is nothing harmful in the materials, nothing harmful can come out accordingly.

How do we achieve this and what is correspondingly important? Because we now work with lots and lots of composite materials. When I look around here on the table now, with the first small selection of materials, I have a material that is on the table as solid material. The rest is actually all composite materials, i.e. consists of a wide variety of individual components, a wide variety of raw materials. It is therefore important that there is a full declaration that all basic components used are listed, verifiably and verifiably documented.
