Indoor air quality and ventilation challenges during heating season

As heating seasons begin, experts warn against the common mistake of keeping windows closed to conserve heat, which can lead to poor indoor air quality and excessive moisture buildup. While closing windows prevents heat loss, it also traps CO2, dust, pollen, and humidity generated by cooking, showering, and breathing.

High humidity levels can cause condensation on cold surfaces like windows and walls, potentially leading to mold growth. To mitigate these issues, short and intense ventilation is recommended over keeping windows open for long periods.

Technological solutions like the I-Vent decentralized heat recovery system are designed to address these challenges. Such systems allow for continuous air exchange by extracting stale, moist, and CO2-heavy air while bringing in filtered fresh air. By utilizing heat recovery, these systems retain thermal energy that would otherwise be lost, maintaining a comfortable indoor microclimate without the need for open windows.
