In recent years, energy efficiency and energy saving strategies have become priorities for energy policy in most countries, and green energy saving buildings has attracted more attention in the worldwide. The use of passive energy saving natural ventilation strategy can improve the effect of building energy saving and improve the internal microenvironment of the building. This paper introduces and analyzes the passive preheating natural ventilation double skin facade (DSF) comprehensively. The influence of the structural parameters of the double skin facade in cold season ventilation on the preheating ventilation effect is discussed on the basis of the discussion and experiment of an actual double skin facade office building. Further, the energy-saving effect of the passive preheating natural ventilation double skin facade is simulated and verified. The effect of structural parameters of DSF in cold season on the thermal performance is summarized. These corresponding results could provide some reference for the buildings in the similar climate regions.
