Different Times, Different Risks
Buildings after 1990 are free of asbestos, PCB, lead pipes and most classic building pollutants. That is the good news. The 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.
No need to panic — the risks are significantly lower than with older buildings. But there are 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 — the so-called sick building syndrome.
VOC Measurement →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.
Formaldehyde Measurement →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 104 radon protection zones. 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 3+ months
- Health complaints: Headaches, fatigue, irritated eyes or airways
- Radon protection zone: 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 — no comprehensive pollutant check as required for older buildings.
Frequently Asked Questions About New Builds
The classic building pollutants (asbestos, PCB, lead) are effectively excluded. But 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 one of the 104 radon protection zones: 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 protection zone, or after renovations with many new materials.
Clarity for little cost
New builds are not automatically pollutant-free. A VOC measurement or a radon measurement gives you certainty — quote after a free initial consultation. Especially if you live in a radon protection zone or notice persistent smells.
