Abstract
⺠We model a 48,000 ft2 commercial building lighting system with AC and DC circuits. ⺠At 2012 efficacies and costs, LEDs are lowest levelized annual cost (LAC) option. ⺠DC LEDs can lead from an LAC increase of 5% to a decrease of 15% (vs. AC LEDs). ⺠Grid-connected DC LEDs with PV can lower LACs by 2-21% (vs. PV-AC LEDs). ⺠PV-DC LEDs may match the LAC of grid-powered AC fluorescents by â¼2013.
