The Goodwin Hall Smart Building uses 200+ accelerometers and Operational Modal Analysis to track modal parameters over the life of the building. The objectives of this research are:
- Refine methods for automated moda analysis
- Understand the impact of environmental parameters (wind, temperature, occupancy) on the response of the structure.

We have developed a public, open-source MATLAB library for Operational Modal Analysis. Access it here.
