Analysis Application Research of an Improved Value Coefficient Method in the Scheme Optimization of the Existing Building Energy Saving Reconstruction

The paper aims to provide a new way for energy saving reconstruction scheme optimization.In order to seek the most reasonable and scientific energy saving reconstruction scheme for the existing buildings.The writers introduce an improved value coefficient method.In the method,the triangular fuzzy number is employed to determine the weights of the function sub-indexes.The paper also proposes that the cost coefficient should adopt the annual value of the life cycle cost.And then the writers establish a corresponding analysis model and offer a detailed elaboration on its application based on a project case of existing building energy saving reconstruction.
