Abstract: Using British data on over 7 million residential property sales, we find that the simplified energy efficiency (EE) information leads to important market effects. UK legislation requires the use of an energy label that shows an EE rating score (1–100) mapped into arbitrary color-coded rating bands (A–G). Applying a regression discontinuity design, we document significant price discontinuities at rating band thresholds, indicating heuristic thinking in the market. These price discontinuities influence market behavior as sellers are more likely to make EE investments if their property is just below a threshold. We discuss policy considerations and avenues for future research.
