At the moment, synthetic materials have a special right to be used in building waterproofing, sanitary, electrical and heating installations. For example, there are long-standing functional wooden gutters and water ducts, foundations in the water and soil areas, and even wood fireplaces, but in the current construction practice, these variants are available for today’s buildings and installations for reasons of liability, availability in the trade And the lack of experience in the application almost no importance.
However, high energy consumption is generally required for the production of synthetic materials. For the construction of plants and buildings with such building materials and installations, the total energy balance expended for this purpose is ultimately higher than the actually expected savings due to the respective function of the component. For example, one should take account of batteries, solar panels or highly effective insulations, which in turn only function when films, adhesives and seals are used for energy-intensive industrial production. Not only in the view of the skyline of Frankfurt- “Mainhatten” is the fact that in our modern buildings complex air-conditioning and ventilation systems are unavoidable as technical solutions in order to be able to use these plants and buildings at all.
The advantages of “modern building materials” are, on the one hand, clear with the availability, application experience, convenience and assembly cost savings. On the other hand: when using natural products, the energy required for the production of plants and buildings is primarily owed to transport and mechanical processing. Subsequent modification and elimination of components of this type is less intense than in the case of synthetically produced components, which are made available for energy use after the use or have to be deposited / unpopulated – without the possibility of an impact. You leave the energy circuit; The production energy, once spent, becomes a loss item; The eco-balance for these substances deteriorates.
However, as the construction techniques are constantly changing, the components made of synthetic materials and composites are not really future-proof. As a result, relays, switches, power cables, wastewater pipes, electronic controls require either complex recycling processes and special treatments or generate considerable landfill or disposal costs. Nevertheless, they are worried about the future. Many people are talking about a “styrofoam dummy” in the construction sector, because later generations have to exploit it.
