Balanced ventilation systems (BVS)

Increasingly well insulated buildings with increasingly well sealed shells lead to humidity and odors no longer being able to permeate through the joints. Added to this, is the fact that fresh air cannot enter the house unhindered. This is where a balanced ventilation system (BVS) comes in: These ventilation-supported systems ensure an air exchange by introducing fresh air into the rooms and transporting used air, pollutants and odors away. This increases well-being and prevents moisture damage and mold:

Indoor ventilation maintenance – here’s how it’s done

Testo IAQ Multifunction Meters and Probes support you in all phases of a BVS: From the planning phase through the optimum adjustment, up to regular monitoring of the performance – intuitively, precisely, and taking legal conformity into consideration. Testo IAQ Multifunction Meters can of course be used not only for centralized, but also for decentralized indoor ventilation.
