Cs0.32WO3 plays a significant role in energy-saving building. Generally, Cs0.32WO3 nano particles are prepared into transparent heat insulation coating with good shielding performance in the near infrared region and ultraviolet region. And the environmentally friendly coating is mainly applied to the glasses of buildings to achieve the purpose of energy saving and CO2 reduction.

But do you know why energy-saving building is important nowadays? The construction industry is one of the priority action areas in the world for a transition to a resource-efficient and low carbon economy. In fact, in 2012, buildings globally accounted for 32% of final energy consumption and for one-third of direct and indirect CO2 and particulate matter emissions. Such high energy consumption in buildings is attributable mainly to low thermo-hygrometric performance of the building envelope (poor thermal insulation, low thermal inertia, the presence of thermal bridges, ineffective screening systems, air leaking, etc.), low efficiency of HVAC and lighting systems as well as a still low utilization of renewable energy sources. So, shielding heat radiation in the sunlight is one way to reduce energy consumption, and Cs0.32WO3 is well known as a heat shielding material.
