When buildings make you ill

Healthy indoor air

Healthy indoor air is crucial for health and well-being - at home and at work. We spend up to 90% of the day indoors. Emissions from furnishings, cleaning agents or building materials can have an impact on indoor air quality.

Specific measurements can determine whether so-called "indoor toxins" such as volatile organic compounds (VOCs), formaldehyde or biological germs can cause health problems. We are happy to advise and support you with the relevant clarifications and accompany remediation work.

Radon is a naturally occurring radioactive gas and is found throughout Switzerland. If it enters buildings and accumulates in living spaces, high levels of exposure are possible - with harmful consequences for health.

Measurements in schools and kindergartens are obligatory under the Radiation Protection Ordinance, as are measurements at workplaces exposed to radon (e.g. underground buildings, water supply systems, etc.). Radon exposure should also be known at other workplaces or in living spaces. Building owners are obliged to consider the radon problem when renovating and constructing new buildings and to take precautionary structural radon protection measures. The radon concentration can be measured easily and inexpensively using Dosimeter measure.

Our radon specialists will advise you on the choice of a suitable measurement strategy and on protection and remediation measures.
