| Abstract：In the context of promoting the construction of carbon-neutral urban blocks and the digital intelligence
era，the use of machine learning algorithms to achieve rapid prediction of building carbon emissions in urban
blocks and the interpretation of the impact mechanisms behind them could assist architects in making intelligent
decisions at the pre-design stage of a scheme. Aiming at the problem of insufficient explanatory nature of ma-
chine learning prediction models，this paper aims to develop a paradigm for analysing the non-linear relationship
between multi-scale design elements and building carbon emissions of office blocks based on parameterisation
and SHAP methods. A parametric model was established based on the Wuhan office block case study，and six en-
semble learning algorithms were used to construct a building carbon emission prediction model for office block，
among which the gradient boosting algorithm had the best performance. This model is used as an example to
interpret the non-linear relationship between multi-scale design elements and building carbon emissions in office
blocks，identify key design parameters that affect building carbon emissions，and interpret the influencing mecha-
nisms behind them，so as to assist architects in making intelligent decisions on design solutions. |
