PC Server & Networking

The data are stored on a simple flat-file system. Data from each sensor are collected and stored on the data acquisition system in text format. The data are archived nightly in binary format on the PC server at the demonstration building.

The graphical analysis software is located on the PC, allowing the on-site operator direct access to real-time and historical data. The more sophisticated browsing and statistical analysis tools are of greater use to remote expert users. The project research team has access to the data and visualization software, allowing them to analyze building performance remotely and test the automated diagnostics system.
