Research on organization system of promoting energy efficiency retrofit of existing residential buildings in northern heating areas

Based on the analytic hierarchy process (AHP), discusses the responsibilities and obligations of the central and local governments, enterprises, building owners, users and other relevant subjects in the course of promoting energy efficiency retrofit. Establishes the route selection of the energy efficiency organization system of existing buildings in China based on cities, which provides the systematic solution for exploiting each subjects’ strength and advantages, integrating resources, forming organization system with sound structure, complemental supporting policy, smooth implementing, advanced technology and strict assessment. It definitely has practical reference value for promoting existing building energy efficiency work.
