TL;DR: In this article, the authors used Modelica-based simulation to compare the efficiency of DC building power distribution with an equivalent alternating current (AC) distribution, and showed that using DC distribution can be considerably more efficient: a medium sized office building with DC distribution has an expected baseline of 12% savings, but may also save up to 18%.

TL;DR: This analysis shows that DC systems can be cost-effective in all scenarios that include large capacities of battery storage and onsite solar, whereas for systems without storage, DC distribution is generally not cost- effective.

TL;DR: How typical building loads can benefit from DC input is identified, including bath fans, refrigerators, wall adapters, task lights, and zone lighting, and the development of several prototypes that demonstrate efficiency savings with DC are detailed.

TL;DR: In this paper, the authors used Modelica-based simulation to compare the efficiency of DC building power distribution with an equivalent alternating current (AC) distribution and showed that using DC distribution can be considerably more efficient than AC: a medium office building with DC distribution has an expected baseline of 11% savings, but may save up to 17%.

TL;DR: The Metacapacitors project aims to improve efficiency, functionality and form factor of offline power converters suitable for LED solid-state lighting, with a view to developing an attractive technology platform for load management and power conversion across a broad range of applications as mentioned in this paper.
