Automatic assisted calibration tool for coupling building automation system trend data with commissioning

Abstract A very large number of measurement points are required to calibrate building energy models for the purpose of ongoing commissioning in HVAC systems. Building automation systems (BASs), common in many commercial and institutional buildings, can provide a large fraction of the required data. To reduce the time for BAS trend data analysis and export, a proof-of-concept prototype, called the Automatic Assisted Calibration Tool (AACT) was developed. The tool is a first step toward developing software that can automatically couple trend data for use in ongoing commissioning and calibrating building energy models. The AACT was tested using a case study institutional building, which proved its capacity to extract useful data and calculate indices of energy performance.
