Measurements of Indoor Air Quality for DBNB Certification

The project

Location: Basel
Halter AG
Phases: Implementation
Period: 2020


In Stücki Park in Basel, Haus G ('Block G') was built and certified to the specifications of the SGNI (Swiss Sustainable Building Council). The Swiss certification system of the SGNI is based on the criteria of the internationally applied DGNB (German Sustainable Building Council) standard.

To successfully obtain certification once the construction work is complete, ambient air measurements must be conducted. This monitors the ambient air for contamination due to emissions from materials and construction. These measurements must be conducted by a certified measurement body.

Ecosens AG has held a corresponding S-Cert AG certification since 2014.
