Buildings account for 36% of global electricity consumption, and the proportion is even higher in more developed countries. Among building energy consumption, air conditioning accounts for approximately 39%, and lighting accounts for 25%, highlighting the tremendous potential for energy-saving improvements in these areas.
Buildings are also responsible for 37% of global carbon emissions. Enhancing building energy efficiency not only reduces global electricity consumption but also lowers carbon emissions.
