This paper presents a novel methodology that combines hybridrectangularinput-output Life Cycle analysis and energy simulation methods to comprehensively evaluate the energy, economic, environmental, and social benefits of Energy Efficiency (EE) solutions in residential buildings. Unlike conventional evaluations that focus primarily on operational energy savings, this approach examines 57,660 EE packages, encompassing envelope retrofitting and heating/cooling system upgrades, manufacturing, packaging, installation, maintenance, and operation life cycle phases. The analysis quantifies total energy and greenhouse gas savings, energy and greenhouse gas payback periods, job creation, gross value added, net present value, savings to investment ratio, impacts on family budget, and reduction in premature deaths. Findings demonstrate the superiority of this holistic approach, providing policymakers with enhanced insights for designing effective EE policies. The study also identifies region-specific optimal EE packages underlining the importance of integrating additional life cycle phases in the policy making process and emphasizing the importance of tailored regional strategies.
