Ventilated Attic Hygrothermal Performance in Nordic Climate, 2021-2022 Field Study

Tampere University researchers collected field data from six test buildings during 2021 and 2022. The dataset contains temperature and relative humidity measurements at 10-minute intervals inside ventilated attics. It also includes carbon dioxide concentration data used as a tracer gas for air change rate measurements.

Use Cases

• Model validation for hygrothermal simulation software based on field-measured temperature and humidity data.
• Analyzing attic ventilation effectiveness based on tracer gas air change rate measurements.
• Studying moisture risk and condensation potential in Nordic building attics based on relative humidity time-series.
• Calibrating building energy models using high-resolution (10-minute) environmental sensor data.

Strengths

• Data originates from a controlled field study at a university's test buildings.
• Measurements were taken at a high temporal resolution of 10-minute intervals.
• Covers a two-year period (2021-2022), capturing seasonal variations.
• Includes data from six distinct attics, allowing for comparative analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale ML tasks.
• Geographic scope is limited to the specific test site of Tampere University.
