Quantile treatment effects on the treated (n = 490,994 hourly kWh observations, 118 apartments). We observe significant conservation effects in the health treatment group across all quantiles of electricity use, except for the lowest decile (most energy efficient observations). By contrast, by the end of the experiment, we observe no significant conservation effect with the monetary savings group and observe splurging behavior, particularly among the highest use quantiles. Significance levels are as follows: ***P < 0.01, **P < 0.05, *P < 0.1.
