Abstract: Aspects of the subject technology relate to an energy audit device configured for identifying one or more sources of thermal energy loss. In some implementation, the audit device includes one or more processors, a memory coupled to the processors, a location module coupled to the processors, and one or more environmental sensors. In practice, the processors can be configured to perform various operations including: receiving a first set of environmental measurements, receiving a second set of environmental measurements, and identifying one or more thermal energy leaks at a building location based on the first and second sets of environmental measurements.
