Annual Data Visualization: A Cyclic Contour Plot

[武政孝治]

Hi.

I frequently use VI-Suite and consider it an extremely powerful tool for constructing performance analyses. I presented on the usefulness of VI-Suite at this year's Architectural Institute of Japan conference held at Kyushu University.

VI-Suite can display annual room temperature fluctuations using HeatMap. However, I find it difficult to interpret the overall trend, so I use a contour plot creation script written in Python. The contour plot I created this time processes both time (0-24 hours) and month (January-December) as “cyclical data.”

This allows the daily cycle and annual cycle to connect smoothly, enabling representation as a continuous, uninterrupted graph. Additionally, contours are created every 2°C, and the color map is generated every 1°C.

Changes in peak and bottom room temperature times by season are immediately apparent. The “undulations” and patterns of temperature changes throughout the year become visually easier to understand. The provided script is designed to read the standard 8760-hour single-column data handled by VI-Suite.

We hope this will be added as an additional visualization option alongside the existing heatmap.

Regard.

Hi.

Thanks for the Python script. This looks good so I'll see if I can integrate this with the VI-Suite.
