What is energy saving building materials, green building materials?

Energy-saving building material is a kind of material used to reduce building energy consumption, mainly including: hollow coated glass plastic energy-saving window, which can prevent ultraviolet radiation, isolate outdoor noise and maintain indoor heat in winter; exterior wall insulation system materials, used to reduce energy consumption in buildings and eliminate heat island effect; interior wall tile veneer ring. Materials are used to avoid pollution and reduce indoor cooling and heating energy loss. The buildings that use these materials can achieve the effect of "cool in winter and cool in summer", which is both energy saving and comfortable. In the case of such a shortage of energy, the promotion of energy-saving building materials should be of great practical significance.
