Abstract
First of all, both the construction of energy-efficient buildings and green buildings are analyzed on the existing buildings to put forward reconstruction strategies for energy conservation and green building. Optimizing air conditioning, natural ventilation, reducing noise, lighting and other measures are carried out in the case to improve building health comfort degree. For the security of energy-saving renovation of historical buildings, the application of insulation materials is put forward in the case to solve the contradiction between energy- saving renovation of historical buildings and fire prevention. Through the comparison of tested data before and after the reconstruction, the effect of green reconstruction is objectively evaluated to provide reference for the application of technology of green reconstruction of domestic existing buildings.
