A system for and method of modeling thermal performance characteristics of HVAC components in a building uses the building power or other meter to measure power consumed by the components. The models are used to test the components, preferably during off hours, to ensure proper and efficient operation. Preferably, the testing software is written in a high-level interpretive language that is independent of the HVAC component being modeled. The models are adaptively maintained by periodically ensuring that their measured output matches the predicted output. When the two do not match, the model parameters are updated. These models can also be used to generate reports comparing costs and cost savings for different temperature and other environmental settings within selected zones in the building.

A television receiver includes circuitry that quickly derives a channel map for a DTV receiver. The apparatus includes tuner that is controlled by a processor in the television receiver to periodically test each channel frequency to determine the strength of the signal at that frequency. If the signal strength exceeds a threshold value, the channel map is updated to indicate that a channel exists at that frequency. The processor monitors the signal recovered by the tuner during normal television viewing for valid program information. If the processor does not detect valid program information for a channel in the program map, the threshold value used by the processor to build the channel map is raised. If the processor detects valid program information then information on the estimated noise level in the received DTV signal is used to update the threshold value. In one embodiment of the invention, the television receiver includes both a main tuner and an auxiliary tuner. The auxiliary tuner is controlled to periodically scan the television channel frequencies to update the channel map, even when the main tuner is being used by a viewer who is watching television.
