Abstract

fetched live from OpenAlex

The development of reliable building energy models at the urban scale is crucial for analyzing and optimizing the energy efficiency of cities. The bottom-up physics-based approach has been widely employed in Urban Building Energy Models (UBEMs). However, the uncertainty of input parameters can impact the reliability of UBEM simulation outputs, and very limited studies considered the uncertainty when developing archetype models for UBEMs. While UBEMs typically rely on a traditional deterministic approach, incorporating probabilistic methods can significantly enhance simulation accuracy by accounting for uncertain variables. Probabilistic methods involve characterizing key uncertainties in input data using Probability Distribution Functions (PDFs). Yet, the effect of using different PDF types on UBEM results is not adequately understood, and the literature often assumes uniform distribution. In this study, UBEM is characterized based on three methods. The deterministic approach is used to serve as a baseline, and two different PDF types are used to examine how PDFs impact simulation results when uncertain parameters are present in UBEMs. Latin Hypercube Sampling (LHS) is employed to propagate uncertainty in input parameters in UBEM. The study is conducted on a case study area of the Marina district of Lusail City, Qatar, characterized by a hot and arid climate.

Full frame distilled prediction

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.
