HumidityWhy relative humidity alone does not tell the complete story
Relative humidity changes with temperature, so two percentages at different temperatures cannot show on their own which air contains more moisture.

Humidity
Moisture and ventilationHow indoor and outdoor vapour pressure can improve ventilation advice
Vapour pressure makes indoor and outdoor moisture more comparable, helping indicate whether a short period of ventilation is likely to support drying.

Condensation evidenceWhat dew point means inside a property
Dew point connects air temperature and moisture, helping explain when a cooler surface may be more likely to collect condensation.
Read the guide →Damp and mould evidenceHow environmental monitoring supports mould investigations
Monitoring adds time, room and outdoor context to a mould investigation without treating sensor readings as a diagnosis.

Workplace environmentsWhat short-term workplace environmental monitoring can reveal
A time-bound workplace assessment can compare CO₂, temperature, humidity and outdoor conditions through occupied and unoccupied periods.
Read the guide →Workplace ventilationWhy one workplace room can have much higher CO₂ than another
Room use, occupancy, ventilation paths and recovery time can make workplace CO₂ patterns differ substantially between neighbouring spaces.

Evidence and limitationsWhat environmental sensors can—and cannot—diagnose
Environmental sensors reveal patterns and changes over time, but readings alone do not diagnose a building defect, mould source or ventilation failure.

Heat-up and cool-down behaviour answer different questions—and neither should be interpreted alone.
