Automation
Can ventilation adjust automatically to CO2 or humidity?
Short answer
Yes. Demand-controlled systems raise the airflow when CO2 or humidity rises and lower it when the room is empty. Milieu Centraal mentions a € 400 subsidy from 2026 combined with insulation (NL).
Explanation
Sensors measure per room or centrally. The system then chooses between settings by itself. That way you get enough fresh air when needed, with less energy and noise when possible. The CO2 references for workplaces (900 or 1200 ppm) are a useful benchmark.
Rules of thumb
- NL: € 400 subsidy from 2026 when combined with insulation (according to Milieu Centraal). [SW-S30]
- Manual system D: setting 1 when away, setting 2 when present, setting 3 for cooking and showering. [SW-S31]
- Reference for workplaces BE: < 900 ppm, or < 1200 ppm with extra measures. [SW-S18]
Pitfalls
- Sensors must stay calibrated and clean; check them at each service. [SW-S31]
By region
- Netherlands
- Subsidy according to Milieu Centraal (reference date 2026-09-27). [SW-S30]
