Building recommissioning is essential in the aging building stock to maintain ecient and comfortable operation as equipment ages and portions of the building are re-purposed for uses other than what was originally intended. Model-based recommissioning provides a way to evaluate payback and incentives for equipment replacement, and the response of the building to optimized operational strategies - without disturbing the comfort or productivity of current occupants. Accurate models are needed for these investigations, which must be calibrated to available sensor data. In this work, cheap wireless temperature transmitters are installed in a 40 year old building to gain information about the performance of the building's envelope for model calibration purposes. The goal is to have a calibrated energy model that is sucient for control system optimization. To perform this task, a detailed model is built and parameters of this model are calibrated by using feedback control to identify components of zone heat balances. Uncertainty and sensitivity analysis along with optimization are used to calibrate parameters so that heat transfer through the envelope is captured accurately
