  1. All models examined the experimental stimuli’s effect on total daily household energy usage (kWh) during the 4-week intervention period. In all four columns, we report regression coefficients with Driscoll and Kraay standard errors. Errors were not clustered, given that the randomization was performed at the apartment level. The estimations in columns 1 and 3 are on the sample of days where the daily maximum temperatures are below the mean and median daily maximum temperature during the same period, respectively. And the estimations in columns 2 and 4 are on the sample of days where the daily maximum temperatures exceed the mean and median daily maximum temperature during the same period, respectively. The third row shows the difference in ATEs between the two treatment groups: the group that received a standard social norm message and the group that received an enhanced social norm message. Standard errors in parentheses; p value < 0.10*; p value < 0.05**; p value < 0.01***.
