Thought in the Optimization of Energy-saving Reconstruction for Existing Buildings

Energy-saving reconstruction for the existing buildings has great significance in energy-saving and protecting environment.The energy-saving targets and energy-saving reconstruction measures were proposed according to structural types and residual service life.And the software of energy-saving design was used to calculate the indices of energy-saving reconstruction.The optimal scheme was chosen by the comparative analysis on the total energy-saving ratio and the cost of energy-saving reconstruction,which proves that the optimization of energy-saving reconstruction for the existing buildings is a new way to go for building energy-saving.
