Whole-Building Diagnostician
The Whole-Building Diagnostician (WBD) is a modular diagnostic software system that provides detection and diagnosis of common problems associated with the operation of heating, ventilating, and air-conditioning (HVAC) systems and equipment in buildings. The WBD tracks overall building energy use, monitors the performance of air-handling units, and detects problems with outside-air control. Its development is part of the commercial buildings research program of the U.S. Department of Energy's Office of Energy Efficiency, and Renewable Energy Building Technologies Program.
