Abstract

Driven by the 'dual carbon' goals, energy efficiency renovation of existing residential buildings has become a critical measure for achieving sustainable development in the construction sector. This paper explores various technical pathways for energy efficiency renovation, including building envelope, heating and cooling systems, and renewable energy applications. Using scientific methods, the economic, environmental, and social benefits of energy efficiency renovation are quantitatively assessed, clarifying the energy-saving potential and cost-benefit relationships of different technology combinations. The research findings provide comprehensive technical guidance and decision-making support for the energy efficiency renovation of existing residential buildings, aiding the green and low-carbon transformation of the construction industry and playing a significant role in promoting efficient energy use and environmental protection.
