Air tightness measurements with blower door measurement method

In well-insulated buildings, up to 60 % of heating energy can be lost through gaps and cracks in the building envelope. Energy-efficient construction can therefore only be achieved with a high degree of airtightness of the building envelope. In addition, this prevents structural damage due to condensation as well as the penetration of drafts, noise or odors.

GI Good indoor climate

The GI GUTES INNENRAUMKLIMA® label offers building owners security with regard to the indoor climate in new buildings and conversions as well as in existing buildings. To obtain the label, qualified measuring institutes check that the highest standards of indoor air quality are met.

Neophytes in the Valais Alps

Neophytes are alien plant species that were introduced after 1500 and have become established in the wild. These include popular garden plants such as the vinegar tree, the summer lilac or the cherry laurel. Invasive species spread so rapidly that they displace other native species that are characteristic of the habitat in question, which can lead to a decline in biodiversity.

Rynetel wildlife transfer

Wildlife corridors are part of the ecological infrastructure. The AG6 wildlife corridor in the Rohr-Rupperswil forest area is one of the most important in Switzerland. The wildlife overpasses aim to create a trouble-free network of paths for wild animals across cantonal borders.

Ecosens AG processes PFAS contaminated sites

Investigation and remediation of suspected sites with the emerging pollutant group PFAS (per- and polyfluorinated alkyl compounds). The substances in the PFAS (per- and polyfluorinated alkyl compounds) group are chemically, biologically and thermally very stable due to their structure.
