Propensity Score Matching

Do certified buildings actually save energy — or do they just happen to be newer and larger? PS-Matching isolates the true causal effect by pairing certified and non-certified buildings with similar observable characteristics. Adjust the caliper and watch how the matched sample changes.

Maximum distance allowed between matched pairs. Wider = more matches, less precise.

Each certified building is matched to its nearest non-certified neighbour within the caliper.
