To reduce energy consumption, it is crucial to retrofit existing buildings as 65% of them will still be in use by 2050. However, evaluating their thermal performance for prioritizing retrofits can be cost-prohibitive on a large scale. This study proposes a data-driven framework that uses smart thermostat data to target buildings for retrofits. Validation of the framework was done using real-time measurements from 60,000 homes across North America. The results can be used to prioritize buildings for retrofits when limited information is available.
At least 65% of existing residential buildings will still be in use by 2050, thus retrofitting existing buildings is critical to reducing energy consumption. However, prioritizing building retrofits typically requires a thorough evaluation of their thermal performance, which can be cost-prohibitive, especially on a large scale. To this end, this study presents a data-driven framework to target buildings for retrofits using smart thermostat data. To validate the framework, it was applied to 60,000 homes across North America using four years of real-time measurements. First, grey-box modelling approaches were used to estimate the thermal time constant for each home. Homes were then clustered according to their estimated values and for each cluster, the priority of retrofit was ranked. Finally, a classification model was developed to predict the priority of retrofit. Using a large sample size, the results can be used to prioritize buildings for retrofits when limited information is available.
