This paper evaluates the predictive power of building energy performance certificates on ex-post home heat loss. Improving the insulative capacity of residential properties is a policy priority in many markets, with building energy performance certificates providing the indicative benchmark. We...

This paper evaluates the extent with which Energy Performance Certificates (EPCs) reflect observed energy used for heating. We use high-frequency smart thermostat panel data in combination with building characteristics and hourly weather information. We exploit variations in boiler operation in...
