Abstract: The virtual simulation technology is applied to energy saving building to solve the problem of public's energy awareness is weak and inadequate knowledge of energy conservation. Taking the "Tian Di Hui Cheng" residential area in Zhengzhou as study subject, according to the Zhengzhou climate conditions and base location of residential area for energy saving design, using the SketchUP software complete energy-saving design show, 3dsmax in modeling, rendering and animation production, VRP software used in virtual reality production, so that the general public could "personally on the scene" understanding of energy-saving building, be helpful for energy saving principle, energy saving knowledge publicity and popularization.
