Abstract

fetched live from OpenAlex

Building energy simulation models are useful for optimizing building systems, detecting and diagnosing faults, and making retrofit decisions. However, these models need to be calibrated with building data to accurately represent building systems. Bayesian calibration approaches have been developed to address the uncertainties in building behavior, but most of them are designed for monthly or yearly operational data. In this study, we propose a novel framework for Bayesian calibration of building energy models using sub-hourly building operational data. The framework employs parametric modeling methods for surrogate modeling and model inadequacy representation to improve computational efficiency and enable calibration with large time series datasets. In addition, it uses variational inference for the estimation of the posterior distribution over uncertain parameters. Our simulation study shows that the proposed Bayesian calibration framework provides reliable and cost-effective calibration of a building energy simulation model with a large time series dataset. With the proposed framework, it is expected that users can have well-calibrated detailed building models that can be used for whole building level problems (e.g., M&V, retrofit) as well as subsystem level control and maintenance with a proper level of risk assessment.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
