抄録	Urban Building Energy Modelling (UBEM) application has become a powerful tool for stakeholders to understand the impacts of the building sector and its role in contributing to climate policies through the simulation of future scenarios. Current UBEM validation has not been explicitly tailored to these applications despite the growing demand from model ‘consumers’, such as policy makers, who may not be aware of UBEM limitations. A model agnostic temperature–time framework was developed and applied to three municipalities in Japan. This identified the influence of temperature-related bias in energy demand estimates by examining the distribution of error across the temperature–time domain as well as comparing the temperature elasticity of modelled energy consumption. All municipalities recorded Coefficient of Variance Root Mean Square Error (CVRMSE) <30 % for both weekday and weekend conditions while only 4 municipal-day type pairs met the Normalized Mean Bias Error (NMBE) criteria of being within ±10 %. Despite meeting these conventional standards, no municipality was able to pass all the temperature–time criteria proposed in the framework highlighting a gap in conventional metrics due to the persistence of temperature–time biases. Notably, no city, and only 1 % of districts, were able to simulate cooling elasticity effectively. The stringent nature of the proposed temperature–time framework suggests it presents an aspirational target for ‘future-proof’ UBEM and a means for increased model transparency.
