Double-Glazed Green Façade Thermal Measurements from Subtropical Field Study

70 days of 5-minute interval measurements compare three double-glazed facade configurations in Nantong, China. The dataset includes raw temperature, heat flux, and environmental parameters like solar irradiance and humidity. Francis Deng Clement collected the data during June-August 2024 for a study supported by the Natural Science Foundation of Jiangsu Province.

Use Cases

• Model heat flux reduction using temperature measurements at multiple cavity elevations and solar irradiance data.
• Compare peak indoor air temperature reduction between the standard, louvered, and green facade configurations.
• Analyze the correlation between environmental parameters like relative humidity, air velocity, and facade thermal performance.
• Calculate daily cooling energy savings from the integrated vertical greenery system using the provided energy calculation files.
• Validate statistical models of facade performance under subtropical climate conditions using the raw measurement time-series.

Strengths

• High-resolution 5-minute sampling interval over a 70-day field study.
• Measurements from calibrated instruments following GUM methodology, including Type T thermocouples and a Kipp & Zonen pyranometer.
• Direct comparison of three distinct facade configurations under identical subtropical climate conditions.

Limitations

• The dataset is very small at 6.2 KB, indicating limited scope and likely a summarized or processed subset of raw data.
• Data is from a single location and one summer season, limiting generalizability to other climates or building types.
• Free-floating conditions with no active HVAC may not represent typical occupied building performance.
