SMA Kebangsaan is a modern school that continues to innovate but still pays attention to efforts to provide sustainable energy. This is done through Sustainable Energy projects in various aspects. One of them is through changing or improving the lighting in the room. A heating and cooling system that is more environmentally friendly, as well as building management that minimizes the best possible use of energy. The construction of new buildings in the future will also be designed in such a way as to reduce greenhouse gas emissions. In addition, policy reforms to facilitate responsible energy use and production are also continuously socialized to the entire academic community of SMA Kebangsaan.
