Research on the Application of Passive Energy-Saving Technology in the Reconstruction of Existing Buildings

This paper puts forward the necessity of active adoption of passive energy saving technology in buildingreconstruction in our country firstly, and then combining practical projects, and the ecological reconstruction theory of Existing Buildings, analyzes and concludes five commonly used passive energy-saving technologies-environment improvement, passive solar power, energy-saving reconstruction of maintenance structure, natural lighting and ventilation and Energy strategy, trying to establish primary methods to apply passive energy-saving technologies to reconstruction of buildings so as to make better use of passive energy-saving technologies in practice.
