在供能形式上，考虑到场景不确定性，方案中以光伏作为主要能源来源，采用水势能+化石能+生物能+风能方式多能互补，弹性供能，实现零能耗的同时能够反哺能源。
Regarding the form of energy supply, taking into account the uncertainty of the scenario, the plan uses photovoltaics as the main energy source, adopting water potential energy + fossil energy + biological energy + wind energy, which complement each other and provide flexible energy supply, which can return energy while achieving zero energy consumption.
建筑从供电到用电器均使用直流电，实现真正意义上的全直流建筑。全直流建筑设计不仅能够降低10%的能源消耗，在插座等用电末端还能将电压控制在人体安全电压内，实现用电安全，风险可控。
The building uses DC power from the power supply to the electrical appliances, realizing a true full DC building. The full DC building design can not only reduce energy consumption by 10%, but also control the voltage at the end of power consumption such as sockets within the safe voltage of the human body, so as to achieve safe electricity use and controllable risks.
