What Is the ASHRAE Duct Fitting Database?

Impact on Energy Efficiency and Sustainability

The relevance of the DFDB extends beyond mere convenience; it is a critical component of global energy efficiency efforts. The HVAC industry is under immense pressure to reduce carbon footprints. Oversizing ductwork or miscalculating pressure drops leads to "parasitic loads"—energy consumed by fans and blowers that does not contribute usefully to the building's environment.
