Electrical equipment in the modern office uses local power adapters to convert alternating current (AC) to direct current (DC). This is not efficient and it releases energy as heat into the workplace, the fluctuation of temperatures within the space adds to the energy cost of the workplace as more cooling is required. DC distribution systems offer offices the opportunity to reduce energy and minimise CO2 emissions. A possible £13 million electricity reduction can be made in London office market alone..

The use of Direct Current in contemporary office space offers potential environmental benefits and energy savings.
