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.

Abstract: A system and method for managing a database of buyers includes a server configured to store a buyers database having data related to a plurality of buyers. For each of the plurality of buyers, the data includes buyer identification information for the buyer, purchasing criteria of the buyer, and buyer agent information associated with the buyer. The server is further configured to retrieve and store in the buyers database supplemental information about each buyer based upon the buyer identification information. The server receives a first query of the buyers database from a first remote device, the first query returning first query results which includes the purchasing criteria and buyer agent information for each buyer included in the first query results. The server transmits the first query results to the first remote device.
