Abstract

In order to continue to give play to the investment benefit of existing buildings, relevant technical specifications were studied and value analysis and technical feasibility justified for extending the service life of existing buildings on the basis of systemic analysis and assessment of the full life cycle of buildings and their initial construction cost, service maintenance cost, demolishing recovery cost, residue treatment cost and the energy consumption and CO2 discharge, with the conclusion that this practice is necessary and feasible. For the subsequent work, research orientation and suggestions on improving the associated laws and regulations and technical standards were proposed.
