Abstract	Machine learning has become an important analytical approach for identifying relationships among explanatory variables and predicting outcomes across complex datasets. Conventional predictive models frequently emphasize statistical associations that improve forecasting accuracy without establishing whether the identified relationships represent causal influences. Consequently, variables receiving substantial predictive importance may not necessarily produce changes in the outcome when modified through an intervention. Causal machine learning combines principles of causal inference with flexible computational modeling to investigate treatment effects, confounding structures, and differences in intervention responses across observational units. The present paper develops a hypothetical methodological framework for examining causal machine learning approaches used to identify factors influencing predictive outcomes. The proposed investigation considers propensity-score adjustment, inverse probability weighting, doubly robust estimation, Bayesian outcome modeling, and honest causal tree methods. A fictional residential energy-efficiency dataset containing 6,000 buildings is introduced to illustrate differences between statistical prediction and causal effect estimation. Building age, baseline electricity consumption, floor area, occupancy, and weather conditions are considered potential explanatory characteristics. The proposed methodology incorporates causal question formulation, treatment definition, directed acyclic graph specification, confounder assessment, propensity modeling, treatment-effect estimation, and sensitivity analysis. Two illustrative analytical tables demonstrate the influence of unequal treatment-group composition on observed electricity consumption comparisons. The constructed example distinguishes unadjusted associations from age-standardized contrasts while emphasizing that neither automatically establishes causality. The methodological discussion examines unmeasured confounding, treatment-selection bias, overlap violations, model misspecification, heterogeneous treatment effects, and uncertainty in causal interpretation. Particular attention is given to the differences among predictive feature importance, conditional association, and intervention-related effects. All numerical values are hypothetical and do not represent completed computational experiments or verified causal findings.
