Driven by the proliferation of DC energy sources and end-use devices (e.g., photovoltaics, battery storage, solid-state lighting, consumer electronics), power distribution in buildings has recently emerged as a path to improved efficiency, resilience, cost savings transitioning building sector. Despite these important benefits, there are several technological market barriers impeding development distribution, which have kept this technology at demonstration phase. This paper identifies specific cases for is viable today. We evaluate their readiness, well cost, resiliency benefits while addressing implementation barriers. The starts with review, followed comprehensive assessment, we analyze field deployments characteristics. also conduct survey professionals through on-site visits phone interviews summarize lessons learned recommendations. In addition, includes novel efficiency analysis, quantify from different categories. Based on our findings, present adoption pathways that can be implemented today, each pathway identify challenges offer recommendations research community.
