Investigating building pollutants in the Pestalozzi school, Stans


In view of the plans to refurbish or renovate the Pestalozzi school, HOLINGER Luzern investigated the building structure and tested the indoor air. The main focus was asbestos, formaldehyde, naphthalene and polycyclic aromatic hydrocarbons (PAH). The indoor air quality measurements have shown the presence of contamination at below risk levels.

The sources of pollutants will be professionally removed during renovations. However, it will not be possible to remove all traces of PAHs, because components of neighbouring buildings also exhibit a degree of contamination. Nonetheless, to ensure that the indoor air is totally clean after work is completed, one classroom is to be completely renovated over the next few months and retested against control measurements.

HOLINGER has aided communications, drafting press releases, assisting at info events for those affected by the project and dealing with queries from the media requiring technical expertise.
