fuktloggar

Fuktloggar are records of moisture conditions collected over time to monitor humidity and moisture-related risk in buildings, storage facilities, or materials. They are typically created with data loggers or hygrometers that continuously measure relative humidity and temperature, and sometimes surface moisture or wood moisture content. The resulting time series is used to assess drying after water intrusion, identify leaks, prevent mold growth, and inform ventilation or dehumidification strategies.

Data loggers are placed at strategic locations such as basements, exterior walls, near plumbing, or inside walls and cavities. Depending on the setup, devices log data at intervals from a few minutes to hours, and store it locally or transmit it to a computer or cloud service. Analysts review trends, compare indoor humidity to outdoor conditions, and look for sustained high humidity, rapid spikes, or drying trends.

Fuktloggar are useful in construction and renovation to verify moisture conditions during and after building; in property management and real estate to support due diligence by documenting moisture exposure; and in archives, food, or pharmaceutical storage to ensure conditions meet preservation or safety requirements.

Interpreting logs requires understanding normal seasonal variation, sensor accuracy, and placement bias. Limitations include calibration drift, sensor aging, data gaps, and the fact that humidity is only one aspect of moisture risk; some assessments may require material moisture content measurements or mold inspections.

Best practices emphasize accurate placement, regular calibration, long monitoring periods to capture seasonal changes, documentation of weather conditions, and clear reporting of thresholds and actions taken.
