CO₂ tips

Track temperature and humidity, but decide when to ventilate using occupancy, CO₂, and moisture sources too. Keep the room cooler without sacrificing fresh air.

Even on warm days, people add CO2 and moisture indoors. Use short, targeted ventilation when the room starts to feel stale.

Shade sunny windows, but do not leave occupied rooms without air exchange all day. Ventilate according to air quality, occupancy and temperature, not a rigid windows-closed rule.
