Different Times, Different Risks
The classic building pollutants such as asbestos, PCB and lead pipes are largely excluded in buildings after 1990. That is the good news. One exception from the transitional period remains: old, biopersistent MMF insulation (mineral wool) was in use until around 2000 and is still possible for construction years between 1990 and around 2000. The remaining challenges of modern buildings lie elsewhere: in the ever more airtight construction methods that trap pollutants from building materials in the indoor air, and in the natural radon risk which is independent of construction year.
For perspective: the risks are significantly lower than with older buildings. There are, however, situations where a measurement is worthwhile.
What to Watch Out for in New Builds
VOC (Volatile organic compounds)
Paints, varnishes, adhesives, floor coverings and furniture off-gas volatile organic compounds. In airtight new builds, these can accumulate and cause headaches, fatigue and mucous membrane irritation; this symptom pattern is known as sick building syndrome.
Formaldehyde
Formaldehyde is the most common individual pollutant in indoor spaces. Sources are chipboard, OSB panels, insulation materials and furniture. Modern products emit less than in the past, but even low concentrations can cause symptoms in sensitive individuals.
Radon
Radon is a naturally occurring radioactive gas from the ground. It enters buildings through cracks and joints, regardless of construction year. In Austria there are radon precaution areas (Radonvorsorgegebiete). New builds can also be affected if the ground slab is not perfectly sealed.
Radon Testing →Mould
Energy-efficient construction with thermal bridges and inadequate ventilation can lead to mould growth. Mould is a biological pollutant that can cause respiratory diseases and allergies. Proper ventilation is essential.
When is a measurement worthwhile?
- Persistent new-build smell: If the typical "new build smell" has not faded after more than 3 months
- Health complaints: Headaches, fatigue, irritated eyes or airways
- Radon precaution area: Radon measurement recommended regardless of construction age
- After renovation: New floor coverings, paints or furniture in large quantities
- Before purchase: Even for new builds, a radon check can be worthwhile
In most cases, a simple VOC indoor air measurement or radon measurement is sufficient; a comprehensive pollutant check as for older buildings is not necessary.
Frequently Asked Questions About New Builds
The classic building pollutants (asbestos, PCB, lead) are largely excluded; old, biopersistent MMF insulation was, however, in use until around 2000 and is still possible for construction years up to around 2000. Beyond that, VOC from building materials can affect indoor air quality, and radon is a geological issue independent of construction year.
The typical smell comes from volatile organic compounds (VOC) off-gassing from paints, varnishes and building materials. In most cases, the concentration decreases significantly within a few months. If symptoms persist, an indoor air measurement is worthwhile.
If your building is in a radon precaution area: yes, definitely. Radon can enter from the ground regardless of construction age. New builds can also be affected.
If there is a persistent new-build smell (more than 3 months), headaches, fatigue or mucous membrane irritation, if the building is in a radon precaution area, or after renovations with many new materials.
Clarity before you decide
New builds are not automatically pollutant-free. Especially if you live in a radon precaution area or notice persistent smells, a VOC or radon measurement gives you certainty. We will tell you the price after the free initial consultation.
