DC Design and Scoping Tool
Fully capture effects of converter losses and
device part-load ratios
Provide a fair comparison between AC and DC design alternatives
Leverage whole-building energy modeling tools to calculate HVAC impacts
Ensure accuracy via thorough experimental validation
DC Technical Potential Savings in 2030U.S. buildings primary energy (electricity): 40 Quadrillion BTUElectricity delivered through power electronics: 80%Estimated savings per converter: 3%
